On 12 March 2013, Galileo satellite GSAT0104, alongside its fellow In-Orbit Validation (IOV) satellites, made history by enabling the first position fix by Europe’s independent satellite navigation system Galileo. Now, after 12 years of service mostly in the area of Search and Rescue, GSAT0104 makes history again by becoming the first satellite in the Galileo constellation to be decommissioned.

What would you do if you suddenly felt an unseen presence, turned around—and found yourself face to face with a seven-foot-tall, insect-like entity? Since 2006, anglers along New Jersey’s Musconetcong River have reported startling encounters with just such a being: a towering, humanoid creature that closely resembles a praying mantis.
But these aren’t just fleeting sightings. Witnesses frequently describe deeply unsettling experiences: telepathic communication, a sense of their thoughts or memories being accessed, and profound physiological effects. Consistent patterns emerge—electronic devices glitch, the surrounding forest falls unnaturally silent, and a strange, low-frequency hum seems to vibrate through the air.
More intriguingly, these mantis-like figures aren’t limited to modern encounters. Strikingly similar forms appear in ancient art across the globe, from 8,000-year-old cave paintings to references in Egyptian iconography. Could these entities have been with us since the dawn of civilization?
Theories vary widely. Some suggest these beings are an advanced species of insectoid extraterrestrials, possibly master geneticists overseeing hybridization programs involving humanity. Others propose a more Earth-bound origin, perhaps they’re a secret lineage of evolved terrestrial insects, hiding in the shadows of time.
And then there’s the interdimensional hypothesis: that these creatures aren’t physical in the way we understand, but exist in a parallel state of reality, occasionally phasing into ours.
Some researchers have even speculated that geological fault lines, like those beneath the Musconetcong River, could serve as energetic gateways, allowing these entities to cross between dimensions.
One thing is clear: the Mantis beings are watching and they may have been here far longer than we’ve dared to imagine.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s coverage of the April 8, 2024, total solar eclipse has earned two nominations for the 46th Annual News & Documentary Emmy Awards.
The Academy of Television Arts & Sciences announced the nominations on May 1, recognizing NASA’s outstanding work in sharing this rare celestial event with audiences around the world. The winners are set to be unveiled at a ceremony in late June.
“Total solar eclipses demonstrate the special connection between our Earth, Moon, and Sun by impacting our senses during the breathtaking moments of total alignment that only occur at this time on Earth,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “NASA’s Eclipse coverage team perfectly encapsulated the awe-inspiring experience from start to finish for viewers around the world in this once-in-a-lifetime moment in American history. Congratulations to the entire NASA Eclipse coverage team for their two much-deserved Emmy award nominations!”
The two nominations include:
Outstanding Live News Special for the agency’s live broadcast coverage of the 2024 total solar eclipse. NASA’s live broadcast coverage of the 2024 total solar eclipse was the most ambitious live project ever attempted by the agency. The broadcast spanned three hours as the eclipse traveled 3,000 miles across seven states and two countries. From cities, parks, and stadiums, 11 hosts and correspondents provided on air commentary, interviews, and live coverage. Viewers tuned in from all over the world, including at watch parties in 9 locations, from the Austin Public Library to New York’s Times Square. An interactive “Eclipse Board” provided real time data analysis as the Moon’s shadow crossed North America. Live feeds from astronauts aboard the International Space Station and NASA’s WB-57 high-altitude research aircraft were brought in to provide rare and unique perspectives of the solar event.
In total, NASA received almost 40 million views across its own distribution. Externally, the main broadcast was picked up in 2,208 hits on 568 channels in 25 countries.
Outstanding Show Open or Title Sequence – News for the agency’s show open for the 2024 total solar eclipse. NASA’s show open for the 2024 total solar eclipse live broadcast explores the powerful connections between the Sun, humanity, and the rare moment when day turns to night. From witnessing the Sun’s atmosphere to feeling the dramatic drop in temperature, the video captures the psychological, emotional, and cultural impact of this celestial phenomenon.

Did you know some of the brightest sources of light in the sky come from the regions around black holes in the centers of galaxies? It sounds a little contradictory, but it’s true! They may not look bright to our eyes, but satellites have spotted oodles of them across the universe.
One of those satellites is NASA’s Fermi Gamma-ray Space Telescope. Fermi has found thousands of these kinds of galaxies since it launched in 2008, and there are many more out there!

Watch a cosmic gamma-ray fireworks show in this animation using just a year of data from the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope. Each object’s magenta circle grows as it brightens and shrinks as it dims. The yellow circle represents the Sun following its apparent annual path across the sky. The animation shows a subset of the LAT gamma-ray records available for more than 1,500 objects in a continually updated repository. Over 90% of these sources are a type of galaxy called a blazar, powered by the activity of a supermassive black hole. NASA’s Marshall Space Flight Center/Daniel Kocevski Black holes are regions of space that have so much gravity that nothing — not light, not particles, nada — can escape. Most galaxies have supermassive black holes at their centers, and these black holes are hundreds of thousands to billions of times the mass of our Sun. In active galactic nuclei (also called “AGN” for short, or just “active galaxies”) the central region is stuffed with gas and dust that’s constantly falling toward the black hole. As the gas and dust fall, they start to spin and form a disk. Because of the friction and other forces at work, the spinning disk starts to heat up.
This composite view of the active galaxy Markarian 573 combines X-ray data (blue) from NASA’s Chandra X-ray Observatory and radio observations (purple) from the Karl G. Jansky Very Large Array in New Mexico with a visible light image (gold) from the Hubble Space Telescope. Markarian 573 is an active galaxy that has two cones of emission streaming away from the supermassive black hole at its center. X-ray: NASA/CXC/SAO/A.Paggi et al; Optical: NASA/STScI; Radio: NSF/NRAO/VLA The disk’s heat gets emitted as light, but not just wavelengths of it that we can see with our eyes. We detect light from AGN across the entire electromagnetic spectrum, from the more familiar radio and optical waves through to the more exotic X-rays and gamma rays, which we need special telescopes to spot.
In the heart of an active galaxy, matter falling toward a supermassive black hole creates jets of particles traveling near the speed of light as shown in this artist’s concept. NASA/Goddard Space Flight Center Conceptual Image Lab About one in 10 AGN beam out jets of energetic particles, which are traveling almost as fast as light. Scientists are studying these jets to try to understand how black holes — which pull everything in with their huge amounts of gravity — somehow provide the energy needed to propel the particles in these jets.
This artist’s concept shows two views of the active galaxy TXS 0128+554, located around 500 million light-years away. Left: The galaxy’s central jets appear as they would if we viewed them both at the same angle. The black hole, embedded in a disk of dust and gas, launches a pair of particle jets traveling at nearly the speed of light. Scientists think gamma rays (magenta) detected by NASA’s Fermi Gamma-ray Space Telescope originate from the base of these jets. As the jets collide with material surrounding the galaxy, they form identical lobes seen at radio wavelengths (orange). The jets experienced two distinct bouts of activity, which created the gap between the lobes and the black hole. Right: The galaxy appears in its actual orientation, with its jets tipped out of our line of sight by about 50 degrees. NASA’s Goddard Space Flight Center Many of the ways we tell one type of AGN from another depend on how they’re oriented from our point of view. With radio galaxies, for example, we see the jets from the side as they’re beaming vast amounts of energy into space. Then there’s blazars, which are a type of AGN that have a jet that is pointed almost directly at Earth, which makes the AGN particularly bright.
Blazar 3C 279’s historic gamma-ray flare in 2015 can be seen in this image from the Large Area Telescope on NASA’s Fermi satellite. During the flare, the blazar outshone the Vela pulsar, usually the brightest object in the gamma-ray sky. NASA/DOE/Fermi LAT Collaboration Fermi has been searching the sky for gamma ray sources since 2008. More than half of the sources it has found have been blazars. Gamma rays are useful because they can tell us a lot about how particles accelerate and how they interact with their environment.
So why do we care about AGN? We know that some AGN formed early in the history of the universe. With their enormous power, they almost certainly affected how the universe changed over time. By discovering how AGN work, we can understand better how the universe came to be the way it is now.

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.
