A native of Gulfport, Mississippi, Williams said he has had the opportunity to work with and be mentored by “some truly exceptional” engineers, some with careers reaching back to the Apollo era.
“I cannot overstate the vast amount of practical knowledge and experience we have at NASA Stennis,” Williams said. “We know how to get things done, and if we do not know, I can guarantee we will figure it out.”
Williams is a senior mechanical design engineer and the structures subject matter expert for the NASA Stennis Engineering and Test Directorate.
He provides technical oversight related to engineering mechanics and machine design by reviewing analysis and design packages from NASA Stennis contractors and NASA engineers for ongoing projects.
Williams also supports projects by performing analysis and creating detailed models, drawings, and system level designs, mostly at the versatile four-stand E Test Complex, where NASA Stennis has 12 active test cells capable of various component, engine, and stage test activities to support the agency and commercial companies.
In support of NASA’s Artemis campaign of returning astronauts to the Moon, Williams also has reviewed structural and pipe stress analysis for the exploration upper stage project that will test a new SLS (Space Launch System) rocket stage to fly on future Artemis missions.
He performed similar review work for Green Run testing of the SLS core stage at NASA Stennis ahead of the successful launch of the Artemis I uncrewed mission around the Moon.
Overall, Williams has been a part of projects on every test stand throughout more than eight years with NASA and five years as a contractor. He has been tasked with solving challenging problems, both individually and as a part of teams.
There were times when he was not sure if he or the team would be able to solve the problem or address it effectively, but each time, the NASA Stennis team found a way.
“Over the span of my career, I have yet to be in a situation where the challenge was not met,” he said.
The opportunity to work with “pretty much all the major space companies in some capacity” is most interesting to Williams. “The best thing is that being a small organization within a relatively small center, there are always opportunities to develop new skills and capabilities to help fill a need or gap,” he said.
No matter the task, Williams looks forward to supporting space innovation while living up to, and maintaining, the standard of excellence associated with NASA for the benefit of all.

Skywatching Skywatching Home What’s Up What to See Tonight Meteor Showers Eclipses Moon Guide More Tips & Guides Skywatching FAQ Night Sky Network Eta Aquarids & Waiting for a Nova!
The first week of May brings the annual Eta Aquarid meteors, peaking on the 6th. And sometime in the next few months, astronomers predict a “new star” or nova explosion will become visible to the unaided eye.
Skywatching Highlights
All Month – Planet Visibility:
Venus: Appears very bright and low in the east in the hour before sunrise all month. Mars: Easy to find in the west in the first few hours of the night, all month long. Sets around midnight to 1 a.m. local time. Jupiter: Shines brightly in the west following sunset all month. Early in the month it sets about two hours after the Sun, but by late May it’s setting only an hour after sunset. Saturn: Begins the month next to Venus, low in the eastern sky before sunrise. Quickly separates from Saturn and rises higher in the sky each day before dawn. Daily Highlights
May 6 – Eta Aquarid Meteors – The peak of this annual shower is early on the morning of May 6th. The two or three nights before that are also decent opportunities to spy a few shooting stars. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. Seeing 10-20 meteors per hour is common for the Northern Hemisphere, while south of the equator, observers tend to see substantially more.
May 3 – Mars & Moon: The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening.
All month – Venus & Saturn: Low in the eastern sky each morning you’ll find bright Venus paired with much fainter Saturn. They start the month close together, but Saturn pulls away and rises higher over the course of the month.
All month – Mars & Jupiter: The planets to look for on May evenings are Mars and Jupiter. They’re visible for a couple of hours after sunset in the western sky.
All month – Corona Borealis: Practice finding this constellation in the eastern part of the sky during the first half of the night, so you have a point of comparison when the T CrB nova appears there, likely in the next few months.
Transcript
What’s Up for May? Four bright planets, morning and night, a chance of meteor showers, and waiting for a nova.
May Planet Viewing
For planet watching this month, you’ll find Mars and Jupiter in the west following sunset. Mars sticks around for several hours after it gets dark out, but Jupiter is setting by 9:30 or 10 p.m., and getting lower in the sky each day. The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening.

They begin the month appearing close together on the sky, and progressively pull farther apart as the month goes on. For several days in late May, early risers will enjoy a gathering of the Moon with Saturn and Venus in the eastern sky before dawn. Watch as the Moon passes the two planets while becoming an increasingly slimmer crescent. You’ll find the Moon hanging between Venus and Saturn on the 23rd.
Eta Aquarid Meteor Shower
Early May brings the annual Eta Aquarid meteor shower. These are meteors that originate from Comet Halley. Earth passes through the comet’s dust stream each May, and again in October. Eta Aquarids are fast moving, and a lot of them produce persistent dust trains that linger for seconds after the meteor’s initial streak.
This is one of the best annual showers in the Southern Hemisphere, but tends to be more subdued North of the Equator, where we typically see 10-20 meteors per hour. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. While the peak is early on the morning of May 6th, the two or three nights before that are also decent opportunities to spy a few shooting stars.
Waiting for a Nova

NASA/JPL-Caltech Astronomers have been waiting expectantly for light from a distant explosion to reach us here on Earth. An event called a nova is anticipated to occur sometime in the coming months. Some 3,000 light years away is a binary star system called T Coronae Borealis, or “T CrB.” It consists of a red giant star with a smaller white dwarf star orbiting closely around it. Now the giant’s outer atmosphere is all puffed up, and the dwarf star is close enough that its gravity continually captures some of the giant’s hydrogen. About every 80 years, the white dwarf has accumulated so much of the other star’s hydrogen, that it ignites a thermonuclear explosion. And that’s the nova.
T Coronae Borealis is located in the constellation Corona Borealis, or the “Northern Crown,” and it’s normally far too faint to see with the unaided eye. But it’s predicted the nova will be as bright as the constellation’s brightest star, which is about as bright as the North Star, Polaris. You’ll find Corona Borealis right in between the two bright stars Arcturus and Vega, and you can use the Big Dipper’s handle to point you to the right part of the sky. Try having a look for it on clear, dark nights before the nova, so you’ll have a comparison when a new star suddenly becomes visible there.

NASA/JPL-Caltech Now, you may have heard about this months ago, as astronomers started keeping watch for the nova midway through 2024, but it hasn’t happened yet. Predicting exactly when novas or any sort of stellar outburst will happen is tricky, but excitement began growing when astronomers observed the star to dim suddenly, much as it did right before its previous nova in 1946. When the nova finally does occur, it won’t stay bright for long, likely flaring in peak brightness for only a few days. And since it’s not predicted again for another 80 years, you might just want to join the watch for this super rare, naked eye stellar explosion in the sky!
Here are the phases of the Moon for May.

8 Min Read How to Contribute to Citizen Science with NASA
A number of NASA projects use mobile phone apps to put satellite data into the palm of your hand, and allow intrepid citizen scientists to upload data. Credits:
NASA A cell phone, a computer—and your curiosity—is all you need to become a NASA citizen scientist and contribute to projects about Earth, the solar system, and beyond.
Science is built from small grains of sand, and you can contribute yours from any corner of the world.
All you need is a cell phone or a computer with an internet connection to begin a scientific adventure. Can you imagine making a pioneering discovery in the cosmos? Want to help solve problems that could improve life on our planet? Or maybe you dream of helping solve an ancient mystery of the universe? All of this is possible through NASA’s Citizen Science program.
NASA defines citizen science, or participatory science, as “science projects that rely on volunteers,” said Dr. Marc Kuchner, an astrophysicist and the Citizen Science Officer in the agency’s Science Mission Directorate in Washington, D.C.
For decades, volunteers have been supporting NASA researchers in different fields and in a variety of ways, depending on the project. They help by taking measurements, sorting data from NASA missions, and deepening our understanding of the universe and our home planet. It all counts.
“That’s science for you: It’s collaborative,” said Kuchner, who oversees the more than 30 citizen science projects NASA offers. “I connect the public and scientists to get more NASA science done.”
NASA astrophysicist Marc Kuchner is a pioneer in participatory science and today serves as NASA’s Citizen Science program officer. In 2014, Kuchner created the Disk Detective project, which helps NASA scientists study how planets form. Kuchner has also been the principal investigator for some of the agency’s many citizen science projects, but today he oversees the portfolio and promotes volunteer participation around the world.

Citizen scientists can come from anywhere in the world—they do not have to be U.S. citizens or residents. Volunteers help NASA look for planets in other solar systems, called exoplanets; sort clouds in Earth’s sky; observe solar eclipses; or detect comets and asteroids. Some of those space rocks are even named after the volunteers who helped find them.
Mass participation is key in initiatives that require as many human eyes as possible. “There are science projects that you can’t do without the help of a big team,” Kuchner said. For example, projects that need large datasets from space telescopes—or “things that are physically big and you need people in different places looking from different angles,” he said.
One example is Aurorasaurus, which invites people to observe and classify northern and southern auroras. “We try to study them with satellites, but it really helps to have people on the ground taking photos from different places at different times,” he explained.
“Part of the way we serve our country and humankind is by sharing not just the pretty pictures from our satellites, but the entire experience of doing science,” Kuchner said.
More than 3 million people have participated in the program. Kuchner believes that shows how much people want to be part of what he calls the “roller coaster” of science. “They want to go on that adventure with us, and we are thrilled to have them.”
The dream of discovering
“You can help scientists who are now at NASA and other organizations around the world to discover interesting things,” said Faber Burgos, a citizen scientist and science communicator from Colombia. “Truth be told, I’ve always dreamed of making history.”
Colombian citizen scientist Faber Burgos studied Modern Languages at the Colombian School of Industrial Careers and has a university degree in Classical Archaeology. Today, he is dedicated to disseminating science content through his social media accounts, focusing on children. In 2020, he and his team launched a balloon probe into the stratosphere with a camera that captured the curvature of the Earth, with the aim of demonstrating that the Earth is round. The video of that feat exceeds 97 million views on his Facebook account, earning him a Guinness World Record.
Credit: Courtesy of Faber Burgos Burgos has been involved in two projects for the past four years: the International Astronomical Search Collaboration (IASC), which searches the sky for potentially dangerous asteroids, and Backyard Worlds: Planet 9. This project uses data from NASA’s now-completed Wide-field Infrared Survey Explorer (WISE) and its follow-up mission, NEOWISE, to search for brown dwarfs and a hypothetical ninth planet.
“There are really amazing participants in this project,” said Kuchner, who helped launch it in 2015. NASA’s WISE and NEOWISE missions detected about 2 billion sources in the sky. “So, the question is: Among those many sources, are any of them new unknowns?” he said.
The project has already found more than 4,000 brown dwarfs. These are Jupiter-sized objects—balls of gas that are too big to be planets, but too small to be stars. Volunteers have even helped discover a new type of brown dwarf.
Participants in the project are also hopeful they’ll find a hypothetical ninth planet, possibly Neptune-sized, in an orbit far beyond Pluto.
The Backyard Worlds: Planet 9 citizen science project asks volunteers to help search for new objects at the edge of our solar system. The assignment is to review images from NASA’s past WISE and NEOWISE missions in search of two types of astronomical objects: brown dwarfs(balls of gas the same size as Jupiter that have too little mass to be considered stars) and low-mass stars. Or, even, the hypothetical ninth planet of our Sun, known as Planet nine, or Planet X. The image shows an artist’s rendering of such a hypothetical world orbiting far from the Sun.
Credit: Caltech/R. Hurt (IPAC) Caltech/R. Hurt (IPAC) Burgos explained that analyzing the images is easy. “If it’s a moving object, it’s obviously going to be something of interest,” he said. “Usually, when you see these images, everything is still. But if there’s an object moving, you have to keep an eye on it.”
Once a citizen scientist marks the object across the full image sequence, they send the information to NASA scientists to evaluate.
“As a citizen scientist, I’m happy to do my bit and, hopefully, one day discover something very interesting,” he said. “That’s the beauty of NASA—it invites everyone to be a scientist. Here, it doesn’t matter what you are, but your desire to learn.”
The first step
To become a NASA citizen scientist, start by visiting the program’s website. There you’ll find a complete list of available projects with links to their respective sites. Some are available in Spanish and other languages. Many projects are also hosted on the Zooniverse platform, which has been available since 2006.
“Another cool way to get involved is to come to one of our live events,” said Kuchner. These are virtual events open to the public, where NASA scientists present their projects and invite people to participate. “Pick a project you like—and if it’s not fun, pick a different one,” he advised. “There are wonderful relationships to be had if you reach out to scientists and other participants.”
Another way for people to get involved in citizen science is to participate in the annual NASA International Space Apps Challenge, the largest global hackathon. This two-day event creates innovation through international collaboration, providing an opportunity for participants to use NASA’s free and open data and agency partners’ space-based data to tackle real-world problems on Earth and in space. The next NASA International Space Apps Challenge will be October 4-5, 2025.

People of all ages can be citizen scientists. Some projects are kid-friendly, such as Nemo-Net, an iPad game that invites participants to color coral reefs to help sort them. “I’d like to encourage young people to start there—or try a project with one of the older people in their life,” Kuchner said.
Citizen science can also take place in classrooms. In the Growing Beyond Earth project, teachers and students run experiments on how to grow plants in space for future missions. The IASC project also works with high schools to help students detect asteroids.

GLOBE Observer is another initiative with an international network of teachers and students. The platform offers a range of projects—many in Spanish—that invite people to collect data using their cell phones.
One of the most popular is the GLOBE Mosquito Habitat Mapper, which tracks the migration and spread of mosquitoes that carry diseases. “It’s a way to help save lives—tracking the vectors that transmit malaria and Zika, among others,” Kuchner said.
Other GLOBE projects explore everything from ground cover to cloud types. Some use astronomical phenomena visible to everyone. For example, during the 2024 total solar eclipse, participants measured air temperature using their phones and shared that data with NASA scientists.
The full experience of doing science
No prior studies are needed, but many volunteers go on to collaborate on—or even lead—scientific research. More than 500 NASA citizen scientists have co-authored scientific publications.
One of them is Hugo Durantini Luca, from Córdoba, Argentina, who has participated in 17 published articles, with more on the way. For years, he explored various science projects, looking for one where he could contribute more actively.
Durantini Luca participated in one of NASA’s first citizen science projects, launched in 2006: Stardust at home. Still ongoing, this project invites volunteers to participate in the search for evidence of interstellar dust on the aerogel and aluminum foil collectors returned by NASA’s Stardust mission, using an online virtual microscope.

In 2014, he discovered Disk Detective, a project that searches for disks around stars, where planets may form. By looking at images from the WISE and NEOWISE missions, participants can help understand how worlds are born and how solar systems evolve.
“And, incidentally, if we find planets or some sign of life, all the better,” said Durantini Luca.
Although that remains a dream, they have made other discoveries—like a new kind of stellar disk called the “Peter Pan Disk,” which appears young even though the star it surrounds is not.

In 2016, Durantini Luca got the chance to support Disk Detective with his own observations from the southern hemisphere. He traveled to El Leoncito Astronomical Complex (CASLEO), an observatory in San Juan, Argentina. There, he learned to use a spectrograph—an instrument that breaks down starlight to analyze its composition.
He treasures that experience. “Curiously, it was the first time in my life I used a telescope,” he said.

“Several of us are friends already—after so many years of bad jokes on calls,” said Durantini Luca.
“People send me pictures of how they met,” said Kuchner. He said the program has even changed how he does science. “It’s changed my life,” he said. “Science is already cool—and this makes it even cooler.”

Help Classify Galaxies Seen by NASA’s James Webb Space Telescope!
The Galaxy Zoo classification interface shows you an image from NASA’s Webb telescope and asks you questions about it. Image credit: Galaxy Zoo, Zooniverse. Inset galaxy: NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/Z. Levay/A. Pagan NASA needs your help identifying the shapes of thousands of galaxies in images taken by our James Webb Space Telescope with the Galaxy Zoo project. These classifications will help scientists answer questions about how the shapes of galaxies have changed over time, what caused these changes, and why. Thanks to the light collecting power of Webb, there are now over 500,000 images of galaxies on website of the Galaxy Zoo citizen science project—more images than scientists can classify by themselves.
“This is a great opportunity to see images from the newest space telescope,” said volunteer Christine Macmillan from Aberdeen, Scotland. “Galaxies at the edge of our universe are being seen for the first time, just as they are starting to form. Just sign up and answer simple questions about the shape of the galaxy that you are seeing. Anyone can do it, ages 10 and up!”
As we look at more distant objects in the universe, we see them as they were billions of years ago because light takes time to travel to us. With Webb, we can spot galaxies at greater distances than ever before. We’re seeing what some of the earliest galaxies ever detected look like, for the first time. The shapes of these galaxies tell us about how they were born, how and when they formed stars, and how they interacted with their neighbors. By looking at how more distant galaxies have different shapes than close galaxies, we can work out which processes were more common at different times in the universe’s history.
At Galaxy Zoo, you’ll first examine an image from the Webb telescope. Then you will be asked several questions, such as ‘Is the galaxy round?’, or ‘Are there signs of spiral arms?’. If you’re quick, you may even be the first person to see the galaxies you’re asked to classify.
“I’m amazed and honored to be one of the first people to actually see these images! What a privilege!” said volunteer Elisabeth Baeten from Leuven, Belgium.
Galaxy Zoo is a citizen science project with a long history of scientific impact. Galaxy Zoo volunteers have been exploring deep space since July 2007, starting with a million galaxies from a telescope in New Mexico called the Sloan Digital Sky Survey and then, moving on to images from space telescopes like NASA’s Hubble Space Telescope and ESA (European Space Agency)’s Euclid telescope. The project has revealed spectacular mergers, taught us about how the black holes at the center of galaxies affect their hosts, and provided insight into how features like spiral arms form and grow.
Now, in addition to adding new data from Webb, the science team has incorporated an AI algorithm called ZooBot, which will sift through the images first and label the ‘easier ones’ where there are many examples that already exist in previous images from the Hubble Space Telescope. When ZooBot is not confident on the classification of a galaxy, perhaps due to complex or faint structures, it will show it to users on Galaxy Zoo to get their human classifications, which will then help ZooBot learn more. Working together, humans and AI can accurately classify limitless numbers of galaxies. The Galaxy Zoo science team acknowledges support from the International Space Sciences Institute (ISSI), who provided funding for the team to get together and work on Galaxy Zoo. Join the project now.

This artist’s concept depicts a magnetar – a type of neutron star with a strong magnetic field – losing material into space. Shown as thin green lines, the magnetic field lines influence the movement of charged material around the magnetar. NASA/JPL-Caltech Since the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe?
“It’s a pretty fundamental question in terms of the origin of complex matter in the universe,” said Anirudh Patel, a doctoral student at Columbia University in New York. “It’s a fun puzzle that hasn’t actually been solved.”
Patel led a study using 20-year-old archival data from NASA and ESA telescopes that finds evidence for a surprising source of a large amount of these heavy elements: flares from highly magnetized neutron stars, called magnetars. The study is published in The Astrophysical Journal Letters.
Study authors estimate that magnetar giant flares could contribute up to 10% of the total abundance of elements heavier than iron in the galaxy. Since magnetars existed relatively early in the history of the universe, the first gold could have been made this way.
“It’s answering one of the questions of the century and solving a mystery using archival data that had been nearly forgotten,” said Eric Burns, study co-author and astrophysicist at Louisiana State University in Baton Rouge.
How could gold be made at a magnetar?
Neutron stars are the collapsed cores of stars that have exploded. They are so dense that one teaspoon of neutron star material, on Earth, would weigh as much as a billion tons. A magnetar is a neutron star with an extremely powerful magnetic field.
On rare occasions, magnetars release an enormous amount of high-energy radiation when they undergo “starquakes,” which, like earthquakes, fracture the neutron star’s crust. Starquakes may also be associated with powerful bursts of radiation called magnetar giant flares, which can even affect Earth’s atmosphere. Only three magnetar giant flares have been observed in the Milky Way and the nearby Large Magellanic Cloud, and seven outside.
Patel and colleagues, including his advisor Brian Metzger, professor at Columbia University and senior research scientist at the Flatiron Institute in New York, have been thinking about how radiation from giant flares could correspond to heavy elements forming there. This would happen through a “rapid process” of neutrons forging lighter atomic nuclei into heavier ones.
Protons define the element’s identity on the periodic table: hydrogen has one proton, helium has two, lithium has three, and so on. Atoms also have neutrons which do not affect identity, but do add mass. Sometimes when an atom captures an extra neutron the atom becomes unstable and a nuclear decay process happens that converts a neutron into a proton, moving the atom forward on the periodic table. This is how, for example, a gold atom could take on an extra neutron and then transform into mercury.
In the unique environment of a disrupted neutron star, in which the density of neutrons is extremely high, something even stranger happens: single atoms can rapidly capture so many neutrons that they undergo multiple decays, leading to the creation of a much heavier element like uranium.
When astronomers observed the collision of two neutron stars in 2017 using NASA telescopes and the Laser Interferomete Gravitational wave Observatory (LIGO), and numerous telescopes on the ground and in space that followed up the initial discovery, they confirmed that this event could have created gold, platinum, and other heavy elements. But neutron star mergers happen too late in the universe’s history to explain the earliest gold and other heavy elements. Recent research by co-authors of the new study — Jakub Cehula of Charles University in Prague, Todd Thompson of The Ohio State University, and Metzger — has found that magnetar flares can heat and eject neutron star crustal material at high speeds, making them a potential source.

At first, Metzger and colleagues thought that the signature from the creation and distribution of heavy elements at a magnetar would appear in the visible and ultraviolet light, and published their predictions. But Burns in Louisiana wondered if there could be a gamma-ray signal bright enough to be detected, too. He asked Metzger and Patel to check, and they found that there could be such a signature.
“At some point, we said, ‘OK, we should ask the observers if they had seen any,’” Metzger said.
Burns looked up the gamma ray data from the last giant flare that has been observed, which was in December 2004. He realized that while scientists had explained the beginning of the outburst, they had also identified a smaller signal from the magnetar, in data from ESA (European Space Agency)’s INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL), a recently retired mission with NASA contributions. “It was noted at the time, but nobody had any conception of what it could be,” Burns said.
Metzger remembers that Burns thought he and Patel were “pulling his leg” because the prediction from their team’s model so closely matched the mystery signal in the 2004 data. In other words, the gamma ray signal detected over 20 years ago corresponded to what it should look like when heavy elements are created and then distributed in a magnetar giant flare.
Patel was so excited, “I wasn’t thinking about anything else for the next week or two. It was the only thing on my mind,” he said.
Researchers supported their conclusion using data from two NASA heliophysics missions: the retired RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) and the ongoing NASA’s Wind satellite, which had also observed the magnetar giant flare. Other collaborators on the new study included Jared Goldberg at the Flatiron Institute.
Next steps in the magnetar gold rush
NASA’s forthcoming COSI (Compton Spectrometer and Imager) mission can follow up on these results. A wide-field gamma ray telescope, COSI is expected to launch in 2027 and will study energetic phenomena in the cosmos, such as magnetar giant flares. COSI will be able to identify individual elements created in these events, providing a new advancement in understanding the origin of the elements. It is one of many telescopes that can work together to look for “transient” changes across the universe.
Researchers will also follow up on other archival data to see if other secrets are hiding in observations of other magnetar giant flares.
“It very cool to think about how some of the stuff in my phone or my laptop was forged in this extreme explosion of the course of our galaxy’s history,” Patel said.
