Almost a decade ago, then-grad student Kyle Helson contributed to early paperwork for NASA’s EXCITE mission. As a scientist at Goddard, Helson helped make this balloon-based telescope a reality: EXCITE launched successfully on Aug. 31.

Name: Kyle Helson
Title: Assistant Research Scientist
Organization: Observational Cosmology Lab (Code 665), via UMBC and the GESTAR II cooperative agreement with NASA Goddard

How did you know you wanted to work at NASA Goddard?

When I was finishing my physics Ph.D. at Brown University in 2016, I was talking to Ed Wollack and Dave Chuss at Goddard about the NASA postdoc program, and they suggested I apply. Luckily, I got the postdoc fellowship to come here to Goddard to work on cosmic microwave background detector testing and other related research.

I don’t think I would have realized or been interested in coming here had I not had that NASA Space Technology Research Fellowship when I was in grad school and gotten the opportunity to spend some time here and work with Ed and Dave.

What is the name of your team that you’re working with right now?

One of the projects I work on is the Exoplanet Climate Infrared TELescope (EXCITE). EXCITE is a scientific balloon-borne telescope that is designed to measure the spectra of hot, Jupiter-like exoplanet atmospheres in near-infrared light.

What is your role for that?

I do a little bit of everything. During grad school, I worked on the first few iterations of the proposal for EXCITE back in 2015 and 2016.

Over the past few years here at Goddard, I’ve been responsible for parts of a lot of the different subsystems like the cryogenic receiver, the gondola, the electronics, and integration and testing of the whole payload.

Last year, we went to Fort Sumner, New Mexico, for an engineering flight. Unfortunately, we were not able to fly for weather reasons. We went back last month, and I was again part of the field deployment team. We take the whole instrument, break it down, carefully ship it all out to New Mexico, put it back together, test it, and get it ready for a flight.

What is most interesting to you about your role here at Goddard?

What I like about working on a project like EXCITE is that we get to kind of do a little bit of everything.

We’ve been able to see the experiment from concept and design to actually getting built, tested and hopefully flown and then subsequent data analysis after the flight. What I think is really fun is being able be with an experiment for the entire life cycle.

How do you help support Goddard’s mission?

We’re studying exoplanets, which definitely fits within the scientific mission of Goddard. We’re also a collaboration between Goddard other academic institutions, like Arizona State, like Brown University, Cornell, and several other places, and so we’re also members of the larger scientific research community beyond NASA.

We also have a number of graduate students working on EXCITE. Ballooning is a good platform for training students and young researchers to learn how to build and design instruments, do data analysis, etc. One of the missions of NASA and Goddard is to train early career scientists like graduate students and post docs, and balloons provide a good platform for that as well.

Balloon missions like EXCITE also provide a good platform for technology advancement and demonstration in preparation for future satellite missions.

How did you know cosmology was what you wanted to pursue?

When I was a kid, I loved space. I wanted to be an astronaut when I was a kid. I even went to space camp.

The first time I ever got to see physics was a middle-school science class. That was the first time we ever learned physics or astronomy that was deeper than just identifying planets or constellations. We started to learn how we could use math to measure or predict experiments.

When I was in college, I remember talking to my undergraduate academic adviser, Glenn Starkman, and talking about what research I might like to do over the summer between sophomore and junior year of college. I wasn’t really sure what I wanted to do or what I was interested in, and he suggested I talk to some of the professors doing astrophysics and cosmology research and see if they had space for me in their lab.

I ended up finding a great opportunity working in a research lab in college — so it was working in the physics department in Case Western.
That’s where I first started learning about computer-aided design (CAD), and designing things in CAD, and that’s where I first learned how things get made in a machine shop, like on a mill, or a lathe. These skills have come in handy ever since, because I do a lot of design work in the lab. And I was lucky growing up that my dad was really hands-on and liked to fix things and build things and he taught me a lot of those skills as well.

Who has influenced you in your life?

My dad had a big influence. I think all the different people I’ve had the opportunity to learn from and work with who have been mentors along the way. My research advisers, professor John Ruhl in college, professor Greg Tucker in grad school, and Dr. Ed Wollack as a postdoc have all been very influential. Additionally, I have had the opportunity to work with a lot of very good post docs and research scientists during my career, Dr. Asad Aboobaker, Dr. Britt Reichborn-Kjennerud, Dr. Michele Limon, among others.

Throughout a career, there are tons of other people on the way from whom you pick up little things here and there that stick with you. You look back and you realize five years later you still do this one thing a certain way because someone helped you and taught you this skill or technique.

Where is a place you’d like to travel to?

Since I was lucky enough to go to Antarctica in graduate school, I figured that is the hardest continent to travel to, so now I have a mission to go to every continent. I’ve been to North America, I’ve been to South America, I’ve been to Asia, Europe, and Australia and New Zealand, but I’ve never been to Africa.

What are your hobbies, or what do you enjoy doing?

I’m a competitive track cyclist. I started racing bikes in collegiate racing as a grad student at Brown. Many summers I’ve spent many weekends driving and flying all over the U.S. to race in the biggest track cycling events in the country.

What would be your three-word-memoir?

Curious, compassionate, cat-dad.

      4 Min Read NASA Finds ‘Sideways’ Black Hole Using Legacy Data, New Techniques
      Image showing the structure of galaxy NGC 5084, with data from the Chandra X-ray Observatory overlaid on a visible-light image of the galaxy. Chandra’s data, shown in purple, revealed four plumes of hot gas emanating from a supermassive black hole rotating “tipped over” at the galaxy’s core. Credits: X-ray: NASA/CXC, A. S. Borlaff, P. Marcum et al.; Optical full image: M. Pugh, B. Diaz; Image Processing: NASA/USRA/L. Proudfit NASA researchers have discovered a perplexing case of a black hole that appears to be “tipped over,” rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways secret of its central black hole lay hidden in old data archives. The discovery was made possible by new image analysis techniques developed at NASA’s Ames Research Center in California’s Silicon Valley to take a fresh look at archival data from the agency’s Chandra X-ray Observatory.
      Using the new methods, astronomers at Ames unexpectedly found four long plumes of plasma – hot, charged gas – emanating from NGC 5084. One pair of plumes extends above and below the plane of the galaxy. A surprising second pair, forming an “X” shape with the first, lies in the galaxy plane itself. Hot gas plumes are not often spotted in galaxies, and typically only one or two are present.
      The method revealing such unexpected characteristics for galaxy NGC 5084 was developed by Ames research scientist Alejandro Serrano Borlaff and colleagues to detect low-brightness X-ray emissions in data from the world’s most powerful X-ray telescope. What they saw in the Chandra data seemed so strange that they immediately looked to confirm it, digging into the data archives of other telescopes and requesting new observations from two powerful ground-based observatories.

A dark, vertical line near the center shows the curve of a dusty disk orbiting the core, whose presence suggests a supermassive black hole within. The disk and black hole share the same orientation, fully tipped over from the horizontal orientation of the galaxy.NASA/STScI, M. A. Malkan, B. Boizelle, A.S. Borlaff. HST WFPC2, WFC3/IR/UVIS.  The surprising second set of plumes was a strong clue this galaxy housed a supermassive black hole, but there could have been other explanations. Archived data from NASA’s Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile then revealed another quirk of NGC 5084: a small, dusty, inner disk turning about the center of the galaxy. This, too, suggested the presence of a black hole there, and, surprisingly, it rotates at a 90-degree angle to the rotation of the galaxy overall; the disk and black hole are, in a sense, lying on their sides.
      The follow-up analyses of NGC 5084 allowed the researchers to examine the same galaxy using a broad swath of the electromagnetic spectrum – from visible light, seen by Hubble, to longer wavelengths observed by ALMA and the Expanded Very Large Array of the National Radio Astronomy Observatory near Socorro, New Mexico.
      “It was like seeing a crime scene with multiple types of light,” said Borlaff, who is also the first author on the paper reporting the discovery. “Putting all the pictures together revealed that NGC 5084 has changed a lot in its recent past.”

      “Detecting two pairs of X-ray plumes in one galaxy is exceptional,” added Pamela Marcum, an astrophysicist at Ames and co-author on the discovery. “The combination of their unusual, cross-shaped structure and the ‘tipped-over,’ dusty disk gives us unique insights into this galaxy’s history.”
      Typically, astronomers expect the X-ray energy emitted from large galaxies to be distributed evenly in a generally sphere-like shape. When it’s not, such as when concentrated into a set of X-ray plumes, they know a major event has, at some point, disturbed the galaxy.
      Possible dramatic moments in its history that could explain NGC 5084’s toppled black hole and double set of plumes include a collision with another galaxy and the formation of a chimney of superheated gas breaking out of the top and bottom of the galactic plane.
      More studies will be needed to determine what event or events led to the current strange structure of this galaxy. But it is already clear that the never-before-seen architecture of NGC 5084 was only discovered thanks to archival data – some almost three decades old – combined with novel analysis techniques.
      The paper presenting this research was published Dec. 18 in The Astrophysical Journal. The image analysis method developed by the team – called Selective Amplification of Ultra Noisy Astronomical Signal, or SAUNAS – was described in The Astrophysical Journal in May 2024.

      This is a James Webb Space Telescope image of NGC 346, a massive star cluster in the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way’s nearest neighbors. Credits:
      NASA, ESA, CSA, STScI, Olivia C. Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA) NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago.
      In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter. But how? This was puzzling.
      To answer this question, researchers used Webb to study stars in a nearby galaxy that, much like the early universe, lacks large amounts of heavy elements. They found that not only do some stars there have planet-forming disks, but that those disks are longer-lived than those seen around young stars in our Milky Way galaxy.
      “With Webb, we have a really strong confirmation of what we saw with Hubble, and we must rethink how we model planet formation and early evolution in the young universe,” said study leader Guido De Marchi of the European Space Research and Technology Centre in Noordwijk, Netherlands.
      Image A: Protoplanetary Disks in NGC 346 (NIRCam Image)
      This is a James Webb Space Telescope image of NGC 346, a massive star cluster in the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way’s nearest neighbors. With its relative lack of elements heavier than hydrogen and helium, the NGC 346 cluster serves as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe. Ten, small, yellow circles overlaid on the image indicate the positions of the ten stars surveyed in this study. NASA, ESA, CSA, STScI, Olivia C. Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA) A Different Environment in Early Times
      In the early universe, stars formed from mostly hydrogen and helium, and very few heavier elements such as carbon and iron, which came later through supernova explosions.
      “Current models predict that with so few heavier elements, the disks around stars have a short lifetime, so short in fact that planets cannot grow big,” said the Webb study’s co-investigator Elena Sabbi, chief scientist for Gemini Observatory at the National Science Foundation’s NOIRLab in Tucson. “But Hubble did see those planets, so what if the models were not correct and disks could live longer?”
      To test this idea, scientists trained Webb on the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way’s nearest neighbors. In particular, they examined the massive, star-forming cluster NGC 346, which also has a relative lack of heavier elements. The cluster served as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe.
      Hubble observations of NGC 346 from the mid 2000s revealed many stars about 20 to 30 million years old that seemed to still have planet-forming disks around them. This went against the conventional belief that such disks would dissipate after 2 or 3 million years.
      “The Hubble findings were controversial, going against not only empirical evidence in our galaxy but also against the current models,” said De Marchi. “This was intriguing, but without a way to obtain spectra of those stars, we could not really establish whether we were witnessing genuine accretion and the presence of disks, or just some artificial effects.”
      Now, thanks to Webb’s sensitivity and resolution, scientists have the first-ever spectra of forming, Sun-like stars and their immediate environments in a nearby galaxy.
      “We see that these stars are indeed surrounded by disks and are still in the process of gobbling material, even at the relatively old age of 20 or 30 million years,” said De Marchi. “This also implies that planets have more time to form and grow around these stars than in nearby star-forming regions in our own galaxy.”
      Image B: Protoplanetary Disks in NGC 346 Spectra (NIRSpec)
      This graph shows, on the bottom left in yellow, a spectrum of one of the 10 target stars in this study (as well as accompanying light from the immediate background environment). Spectral fingerprints of hot atomic helium, cold molecular hydrogen, and hot atomic hydrogen are highlighted. On the top left in magenta is a spectrum slightly offset from the star that includes only light from the background environment. This second spectrum lacks a spectral line of cold molecular hydrogen.
      On the right is the comparison of the top and bottom lines. This comparison shows a large peak in the cold molecular hydrogen coming from the star but not its nebular environment. Also, atomic hydrogen shows a larger peak from the star. This indicates the presence of a protoplanetary disk immediately surrounding the star. The data was taken with the microshutter array on the James Webb Space Telescope’s NIRSpec (Near-Infrared Spectrometer) instrument. Illustration: NASA, ESA, CSA, Joseph Olmsted (STScI) A New Way of Thinking
      This finding refutes previous theoretical predictions that when there are very few heavier elements in the gas around the disk, the star would very quickly blow away the disk. So the disk’s life would be very short, even less than a million years. But if a disk doesn’t stay around the star long enough for the dust grains to stick together and pebbles to form and become the core of a planet, how can planets form?
      The researchers explained that there could be two distinct mechanisms, or even a combination, for planet-forming disks to persist in environments scarce in heavier elements.
      First, to be able to blow away the disk, the star applies radiation pressure. For this pressure to be effective, elements heavier than hydrogen and helium would have to reside in the gas. But the massive star cluster NGC 346 only has about ten percent of the heavier elements that are present in the chemical composition of our Sun. Perhaps it simply takes longer for a star in this cluster to disperse its disk.
      The second possibility is that, for a Sun-like star to form when there are few heavier elements, it would have to start from a larger cloud of gas. A bigger gas cloud will produce a bigger disk. So there is more mass in the disk and therefore it would take longer to blow the disk away, even if the radiation pressure were working in the same way.
      “With more matter around the stars, the accretion lasts for a longer time,” said Sabbi. “The disks take ten times longer to disappear. This has implications for how you form a planet, and the type of system architecture that you can have in these different environments. This is so exciting.”
      The science team’s paper appears in the Dec. 16 issue of The Astrophysical Journal.

      For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and ‘weighed’ a galaxy, in the early Universe, that has a mass that is similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Found at around 600 million years after the Big Bang, this lightweight galaxy, nicknamed the Firefly Sparkle, is gleaming with star clusters – 10 in total – that researchers examined in great detail. Other galaxies Webb has detected at this period in the history of the Universe are significantly more massive.
