On Tuesday, March 4, 2025, technicians at NASA’s Glenn Research Center in Cleveland help lower student experiments in the 2.2 Second Drop Tower. Credit: NASA/Jef Janis Nineteen teams of students from across the nation in grades 8-12 worked for months in classrooms, labs, basements, and garages for the opportunity to test their projects at NASA’s Glenn Research Center in Cleveland. This spring, the teams’ hard work was put to the test in the 2.2 Second Drop Tower facility at NASA Glenn.
The “2025 Drop Tower Challenge: Paddle Wheel” invited teams to design and build paddle wheels that rotate in water during free fall. The wheels could not rotate by mechanical means. A better understanding of fluid behavior in microgravity could improve spacecraft systems for cooling, life support, and propellants.
On Thursday, May 6, 2025, NASA Glenn Research Center technicians — left to right, John Doehne, Jason West, and Moses Brown — prepare the 2.2. Second Drop Tower for testing student experiments during the 2025 Drop Tower Challenge. Credit: NASA/Jef Janis Based on test performance, analyses, reports, the students’ approach to the challenge, and more, the following teams have been identified as the winners:
First Place: Arth Murarka, Umar Khan, Ishaan Joshi, Alden Al-Mehdi, Rohnin Qureshi, and Omy Gokul (advised by David Dutton), Bellarmine College Preparatory, San Jose, California Second Place: Emma Lai, Keaton Dean, and Oliver Lai (advised by Stephen Lai), Houston, Texas Third Place: Chloe Benner, Ananya Bhatt, and Surabhi Gupta (advised by SueEllen Thomas), Pennridge High School, Perkasie, Pennsylvania “We’re impressed with the variety of designs students submitted for testing in Glenn’s drop tower,” said Nancy Hall, co-lead for the 2025 Drop Tower Challenge. “The teams showed significant creativity and background research through their paddle wheel designs and analysis of results.”
Students from Bellarmine College Preparatory shared how they navigated through the process to earn first place. Using NASA guidelines and resources available to assist students with the challenge, the team submitted a research proposal, including two 3D designs. Learning their team was selected, they reviewed feedback from the NASA staff and set to work.

Credit: Courtesy of Bellarmine College Preparatory To start, students stressed that they conducted a large amount of research and testing of materials to use in their paddle wheels before deciding on the final design.
“I learned that something doesn’t need to be super expensive or complex to work,” said student Umar Khan. “We found that white board sheets or packing peanuts — just household items — can be effective [in the design].”
Student Arth Murarka added, “Our original design looks a lot different from the final.”
Bellarmine staff member and team advisor David Dutton helped the students get organized in the beginning of the process, but said they worked independently through much of the project.

Credit: NASA/Jef Janis Once the design was finalized, the team shipped their hardware to NASA Glenn. NASA technicians then tested how the paddle wheels performed in the drop tower, which is used for microgravity experiments.
Students said they studied concepts including capillary physics and fluid dynamics. They also learned how to write a research paper, which they said they will appreciate in the future.
The team dedicated a lot of time to the project, meeting daily and on weekends.
“We learned a lot of useful skills and had a lot of fun,” Murarka said. “It was definitely worth it.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
An international team of astronomers has uncovered new evidence to explain how pulsing remnants of exploded stars interact with surrounding matter deep in the cosmos, using observations from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) and other telescopes.
Scientists based in the U.S., Italy, and Spain, set their sights on a mysterious cosmic duo called PSR J1023+0038, or J1023 for short. The J1023 system is comprised of a rapidly rotating neutron star feeding off of its low-mass companion star, which has created an accretion disk around the neutron star. This neutron star is also a pulsar, emitting powerful twin beams of light from its opposing magnetic poles as it rotates, spinning like a lighthouse beacon.
The J1023 system is rare and valuable to study because the pulsar transitions clearly between its active state, in which it feeds off its companion star, and a more dormant state, when it emits detectable pulsations as radio waves. This makes it a “transitional millisecond pulsar.”

Credit: Marco Maria Messa, University of Milan/INAF-OAB; Maria Cristina Baglio, INAF-OAB “Transitional millisecond pulsars are cosmic laboratories, helping us understand how neutron stars evolve in binary systems,” said researcher Maria Cristina Baglio of the Italian National Institute of Astrophysics (INAF) Brera Observatory in Merate, Italy, and lead author of a paper in The Astrophysical Journal Letters illustrating the new findings.
The big question for scientists about this pulsar system was: Where do the X-rays originate? The answer would inform broader theories about particle acceleration, accretion physics, and the environments surrounding neutron stars across the universe.
The source surprised them: The X-rays came from the pulsar wind, a chaotic stew of gases, shock waves, magnetic fields, and particles accelerated near the speed of light, that hits the accretion disk.
To determine this, astronomers needed to measure the angle of polarization in both X-ray and optical light. Polarization is a measure of how organized light waves are. They looked at X-ray polarization with IXPE, the only telescope capable of making this measurement in space, and comparing it with optical polarization from the European Southern Observatory’s Very Large Telescope in Chile. IXPE launched in Dec. 2021 and has made many observations of pulsars, but J1023 was the first system of its kind that it explored.
NASA’s NICER (Neutron star Interior Composition Explorer) and Neil Gehrels Swift Observatory provided valuable observations of the system in high-energy light. Other telescopes contributing data included the Karl G. Jansky Very Large Array in Magdalena, New Mexico.
The result: scientists found the same angle of polarization across the different wavelengths.
“That finding is compelling evidence that a single, coherent physical mechanism underpins the light we observe,” said Francesco Coti Zelati of the Institute of Space Sciences in Barcelona, Spain, co-lead author of the findings.
This interpretation challenges the conventional wisdom about neutron star emissions of radiation in binary systems, the researchers said. Previous models had indicated that the X-rays come from the accretion disk, but this new study shows they originate with the pulsar wind.
“IXPE has observed many isolated pulsars and found that the pulsar wind powers the X-rays,” said NASA Marshall astrophysicist Philip Kaaret, principal investigator for IXPE at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These new observations show that the pulsar wind powers most of the energy output of the system.”
Astronomers continue to study transitional millisecond pulsars, assessing how observed physical mechanisms compare with those of other pulsars and pulsar wind nebulae. Insights from these observations could help refine theoretical models describing how pulsar winds generate radiation – and bring researchers one step closer, Baglio and Coti Zelati agreed, to fully understanding the physical mechanisms at work in these extraordinary cosmic systems.

Scientists predict one of the major surveys by NASA’s upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence of some of the universe’s first stars, which are thought to completely self-destruct without leaving any remnant behind.
This simulation showcases the dynamic universe as NASA’s Nancy Grace Roman Space Telescope could see it over the course of its five-year primary mission. The video sparkles with synthetic supernovae from observations of the OpenUniverse simulated universe taken every five days (similar to the expected cadence of Roman’s High-Latitude Time-Domain Survey, which OpenUniverse simulates in its entirety). On top of the static sky of stars in the Milky Way and other galaxies, more than a million exploding stars flare into visibility and then slowly fade away. To highlight the dynamic physics happening and for visibility at this scale, the true brightness of each transient event has been magnified by a factor of 10,000 and no background light has been added to the simulated images. The video begins with Roman’s full field of view, which represents a single pointing of Roman’s camera, and then zooms into one square.Credit: NASA’s Goddard Space Flight Center and M. Troxel Cosmic explosions offer clues to some of the biggest mysteries of the universe. One is the nature of dark energy, the mysterious pressure thought to be accelerating the universe’s expansion.
“Whether you want to explore dark energy, dying stars, galactic powerhouses, or probably even entirely new things we’ve never seen before, this survey will be a gold mine,” said Benjamin Rose, an assistant professor at Baylor University in Waco, Texas, who led a study about the results. The paper is published in The Astrophysical Journal.
Called the High-Latitude Time-Domain Survey, this observation program will scan the same large region of the cosmos every five days for two years. Scientists will stitch these observations together to create movies that uncover all sorts of cosmic fireworks.
Chief among them are exploding stars. The survey is largely geared toward finding a special class of supernova called type Ia. These stellar cataclysms allow scientists to measure cosmic distances and trace the universe’s expansion because they peak at about the same intrinsic brightness. Figuring out how fast the universe has ballooned during different cosmic epochs offers clues to dark energy.
This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.Credit: NASA, ESA, CSA, and STScI In the new study, scientists simulated Roman’s entire High-Latitude Time-Domain Survey. The results suggest Roman could see around 27,000 type Ia supernovae—about 10 times more than all previous surveys combined.
Beyond dramatically increasing our total sample of these supernovae, Roman will push the boundaries of how far back in time we can see them. While most of those detected so far occurred within approximately the last 8 billion years, Roman is expected to see vast numbers of them earlier in the universe’s history, including more than a thousand that exploded more than 10 billion years ago and potentially dozens from as far back as 11.5 billion years. That means Roman will almost certainly set a new record for the farthest type Ia supernova while profoundly expanding our view of the early universe and filling in a critical gap in our understanding of how the cosmos has evolved over time.
“Filling these data gaps could also fill in gaps in our understanding of dark energy,” Rose said. “Evidence is mounting that dark energy has changed over time, and Roman will help us understand that change by exploring cosmic history in ways other telescopes can’t.”
But type Ia supernovae will be hidden among a much bigger sample of exploding stars Roman will see once it begins science operations in 2027. The team estimates Roman will also spot about 60,000 core-collapse supernovae, which occur when a massive star runs out of fuel and collapses under its own weight.
That’s different from type Ia supernovae, which originate from binary star systems that contain at least one white dwarf — the small, hot core remnant of a Sun-like star — siphoning material from a companion star. Core-collapse supernovae aren’t as useful for dark energy studies as type Ias are, but their signals look similar from halfway across the cosmos.
“By seeing the way an object’s light changes over time and splitting it into spectra — individual colors with patterns that reveal information about the object that emitted the light—we can distinguish between all the different types of flashes Roman will see,” said Rebekah Hounsell, an assistant research scientist at the University of Maryland-Baltimore County working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and a co-author of the study.
“With the dataset we’ve created, scientists can train machine-learning algorithms to distinguish between different types of objects and sift through Roman’s downpour of data to find them,” Hounsell added. “While searching for type Ia supernovae, Roman is going to collect a lot of cosmic ‘bycatch’—other phenomena that aren’t useful to some scientists, but will be invaluable to others.”
Hidden Gems
Thanks to Roman’s large, deep view of space, scientists say the survey should also unearth extremely rare and elusive phenomena, including even scarcer stellar explosions and disintegrating stars.
Upon close approach to a black hole, intense gravity can shred a star in a so-called tidal disruption event. The stellar crumbs heat up as they swirl around the black hole, creating a glow astronomers can see from across vast stretches of space-time. Scientists think Roman’s survey will unveil 40 tidal disruption events, offering a chance to learn more about black hole physics.
The team also estimates Roman will find about 90 superluminous supernovae, which can be 100 times brighter than a typical supernova. They pack a punch, but scientists aren’t completely sure why. Finding more of them will help astronomers weigh different theories.
Even rarer and more powerful, Roman could also detect several kilonovae. These blasts occur when two neutron stars — extremely dense cores leftover from stars that exploded as supernovae — collide. To date, there has been only one definitive kilonova detection. The team estimates Roman could spot five more.
NASA’s Roman Space Telescope will survey the same areas of the sky every few days following its launch in May 2027. Researchers will mine these data to identify kilonovae – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.Credit: NASA, ESA, J. Olmsted (STScI) That would help astronomers learn much more about these mysterious events, potentially including their fate. As of now, scientists are unsure whether kilonovae result in a single neutron star, a black hole, or something else entirely.
Roman may even spot the detonations of some of the first stars that formed in the universe. These nuclear furnaces were giants, up to hundreds of times more massive than our Sun, and unsullied by heavy elements that hadn’t yet formed.
They were so massive that scientists think they exploded differently than modern massive stars do. Instead of reaching the point where a heavy star today would collapse, intense gamma rays inside the first stars may have turned into matter-antimatter pairs (electrons and positrons). That would drain the pressure holding the stars up until they collapsed, self-destructing in explosions so powerful they’re thought to leave nothing behind.
So far, astronomers have found about half a dozen candidates of these “pair-instability” supernovae, but none have been confirmed.
“I think Roman will make the first confirmed detection of a pair-instability supernova,” Rose said — in fact the study suggests Roman will find more than 10. “They’re incredibly far away and very rare, so you need a telescope that can survey a lot of the sky at a deep exposure level in near-infrared light, and that’s Roman.”
A future rendition of the simulation could include even more types of cosmic flashes, such as variable stars and active galaxies. Other telescopes may follow up on the rare phenomena and objects Roman discovers to view them in different wavelengths of light to study them in more detail.
“Roman’s going to find a whole bunch of weird and wonderful things out in space, including some we haven’t even thought of yet,” Hounsell said. “We’re definitely expecting the unexpected.”
