Interview with Michiharu Hyogo, Citizen Scientist and First Author of a New Scientific Paper

Peer-reviewed scientific journal articles are the bedrock of science. Each one represents the culmination of a substantial project, impartially checked for accuracy and relevance – a proud accomplishment for any science team. 

The person who takes responsibility for writing the paper must inevitably and repeatedly  write, edit, and rewrite its content as they receive comments and constructive criticism from colleagues, peers, and editors. And the process involves much more than merely re-writing the words. Implementing feedback and polishing the paper regularly involves  reanalyzing data and conducting additional analyses as needed, over and over again. The person who  successfully climbs this mountain of effort can then often earn the honor of being named the first author of a peer-reviewed scientific publication. To our delight, more and more of NASA’s citizen scientists have taken on this demanding challenge, and accomplished this incredible feat.

Michiharu Hyogo is one of these pioneers. His paper, “Unveiling the Infrared Excess of SIPS J2045-6332: Evidence for a Young Stellar Object with Potential Low-Mass Companion” (Hyogo et al. 2025) was recently accepted for publication in the journal Monthly Notices of the Royal Astronomical Society. He conceived of the idea for this paper, performed most of the research using of data from NASA’s retired Wide-field Infrared Survey Explorer (WISE) mission, and submitted it to the journal. We asked him some questions about his life and he shared with us some of the secrets to his success.

Q: Where do you live, Michi?

A: I have been living in Tokyo, Japan since the end of 2012. Before that, I lived outside Japan for a total of 21 years, in countries such as Canada, the USA, and Australia.

Q: Which NASA Citizen Science projects have you worked on?

A: I am currently working on three different NASA-sponsored projects: Disk Detective, Backyard Worlds: Planet 9, and Planet Patrol.

Q: What do you do when you’re not working on these projects?

A: Until March of last year, I worked as a part-time lecturer at a local university in Tokyo. At the moment, I am unemployed and looking for similar positions. My dream is to work at a community college in the USA, but so far, my job search has been unsuccessful. In the near future, I hope to teach while also working on projects like this one. This is my dream.

Q: How did you learn about NASA Citizen Science?

A: It’s a very long story. A few years after completing my master’s degree, around 2011, a friend from the University of Hawaii (where I did my bachelor’s degree) introduced me to one of the Zooniverse projects. Since it was so long ago, I can’t remember exactly which project it was—perhaps Galaxy Zoo or another one whose name escapes me.

I definitely worked on Planet Hunters, classifying all 150,000 light curves from (NASA’s) Kepler observatory. Around the time I completed my classifications for Planet Hunters, I came across Disk Detective as it was launching. A friend on Facebook shared information about it, stating that it was “NASA’s first sponsored citizen science project aimed at publishing scientific papers”.

At that time, I was unemployed and had plenty of free time, so I joined without giving much thought to the consequences. I never expected that this project would eventually lead me to write my own paper — it was far beyond anything I had imagined.

  
Q: What would you say you have gained from working on these NASA projects?A: Working on these NASA-sponsored projects has been an incredibly valuable experience for me in multiple ways. Scientifically, I have gained hands-on experience in analyzing astronomical data, identifying potential celestial objects, and contributing to real research efforts. Through projects like Disk Detective,Backyard Worlds: Planet 9, and Planet Patrol, I have learned how to systematically classify data, recognize patterns, and apply astrophysical concepts in a practical setting.

Beyond the technical skills, I have also gained a deeper understanding of how citizen science can contribute to professional research. Collaborating with experts and other volunteers has improved my ability to communicate scientific ideas and work within a research community.

Perhaps most importantly, these projects have given me a sense of purpose and the opportunity to contribute to cutting-edge discoveries. They have also led to unexpected opportunities, such as co-authoring scientific papers — something I never imagined when I first joined. Overall, these experiences have strengthened my passion for astronomy and my desire to continue contributing to the field.

Q: How did you make the discovery that you wrote about in your paper?

A: Well, the initial goal of this project was to discover circumstellar disks around brown dwarfs. The Disk Detective team assembled more than 1,600 promising candidates that might possess such disks. These objects were identified and submitted by volunteers from the same project, following the physical criteria outlined within it.

Among these candidates, I found an object with the largest infrared excess and the fourth-latest spectral type. This was the moment I first encountered the object and found it particularly interesting, prompting me to investigate it further.

Although we ultimately did not discover a disk around this object, we uncovered intriguing physical characteristics, such as its youth and the presence of a low-mass companion with a spectral type of L3 to L4.

Q: How did you feel when your paper was accepted for publication?

A: Thank you for asking this question—I truly appreciate it. I feel like the biggest milestone of my life has finally been achieved!

This is the first time I genuinely feel that I have made a positive impact on society. It feels like a miracle. Imagine if we had a time machine and I could go back five years to tell my past self this whole story. You know what my past self would say? “You’re crazy.”

Yes, I kept dreaming about this, and deep down, I was always striving toward this goal because it has been my purpose in life since childhood. I’m also proud that I accomplished something like this without being employed by a university or research institute. (Ironically, I wasn’t able to achieve something like this while I was in grad school.)

I’m not sure if there are similar examples in the history of science, but I’m quite certain this is a rare event.

Q: What would you say to other citizen scientists about the process of writing a paper?

A: Oh, there are several important things I need to share with them. 

First, never conduct research entirely on your own. Reach out to experts in your field as much as possible. For example, in my case, I collaborated with brown dwarf experts from the Backyard Worlds: Planet 9 team. When I completed the first draft of my paper, I sent it to all my collaborators to get their feedback on its quality and to check if they had any comments on the content. It took some time, but I received a lot of helpful suggestions that ultimately improved the clarity and conciseness of my paper.

If this is your first time receiving extensive feedback, it might feel overwhelming. However, you should see it as a valuable opportunity—one that will lead you to stronger research results. I am truly grateful for the feedback I received. This process will almost certainly help you receive positive feedback from referees when you submit your own paper. That’s exactly what happened to me.

Second, do not assume that others will automatically understand your research for you. This seems to be a common challenge among many citizen scientists. First, you must have a clear understanding of your own research project. Then, it is crucial to communicate your progress clearly and concisely, without unnecessary details. If you have questions—especially when you are stuck — be specific.

For example, I frequently attend Zoom meetings for various projects, including Backyard Worlds: Planet 9 and Disk Detective. In every meeting, I give a brief recap of what I’ve been working on — every single time — to refresh the audience’s memory. This helps them stay engaged and remember my research. (Screen sharing is especially useful for this.) After the recap, I present my questions. This approach makes it much easier for others to understand where I am in my research and, ultimately, helps them provide potential solutions to the challenges I’m facing.

Lastly, use Artificial Intelligence (AI) as much as possible. For tasks like editing, proofreading, and debugging, AI tools can be incredibly helpful. I don’t mean to sound harsh, but I find it surprising that some people still do these things manually. In many cases, this can be a waste of time. I strongly believe we should rely on machines for tasks that we either don’t need to do ourselves or simply cannot do. This approach saves time and significantly improves productivity.

Q: Thank you for sharing all these useful tips! Is there anything else you would like to add?

A: I would like to sincerely thank all my collaborators for their patience and support throughout this journey. I know we have never met in person, and for some of you, this may not be a familiar way to communicate (it wasn’t for me at first either). If that’s the case, I completely understand. I truly appreciate your trust in me and in this entirely online mode of communication. Without your help, none of what I have achieved would have been possible.

I am now thinking about pushing myself to take on another set of research projects. My pursuit of astronomical research will not stop, and I hope you will continue to follow my journey. I will also do my best to support others along the way.

ESA Previews Euclid Mission’s Deep View of ‘Dark Universe’

NASA - Breaking News - Wed, 03/19/2025 - 9:24am

6 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) This image shows about 1.5% of Euclid’s Deep Field South, one of three regions of the sky that the telescope will observe for more than 40 weeks over the course of its prime mission, spotting faint and distant galaxies. One galaxy cluster near the center is located almost 6 billion light-years away from Earth. ESA/Euclid/Euclid Consortium/NASA; image processing by J.-C. Cuillandre, E. Bertin, G. An-selmi

With contributions from NASA, the mission is looking back into the universe’s history to understand how the universe’s expansion has changed. 

The Euclid mission — led by ESA (European Space Agency) with contributions from NASA — aims to find out why our universe is expanding at an accelerating rate. Astronomers use the term “dark energy” to refer to the unknown cause of this phenomenon, and Euclid will take images of billions of galaxies to learn more about it. A portion of the mission’s data was released to the public by ESA on Wednesday, March 19.

This new data has been analyzed by mission scientists and provides a glimpse of Euclid’s progress. Deemed a “quick” data release, this batch focuses on select areas of the sky to demonstrate what can be expected in the larger data releases to come and to allow scientists to sharpen their data analysis tools in preparation.

The data release contains observations of Euclid’s three “deep fields,” or areas of the sky where the space telescope will eventually make its farthest observations of the universe. Featuring one week’s worth of viewing, the Euclid images contain 26 million galaxies, the most distant being over 10.5 billion light-years away. Launched in July 2023, the space telescope is expected to observe more than 1.5 billion galaxies during its six-year prime mission.

The entirety of the Euclid mission’s Deep Field South region is shown here. It is about 28.1 square degrees on the sky. Euclid will observe this and two other deep field regions for a total of about 40 weeks during its 6-year primary mission. ESA/Euclid/Euclid Consortium/NASA; image processing by J.-C. Cuillandre, E. Bertin, G. An-selmi

By the end of that prime mission, Euclid will have observed the deep fields for a total of about 40 weeks in order to gradually collect more light, revealing fainter and more distant galaxies. This approach is akin to keeping a camera shutter open to photograph a subject in low light.

The first deep field observations, taken by NASA’s Hubble Space Telescope in 1995, famously revealed the existence of many more galaxies in the universe than expected. Euclid’s ultimate goal is not to discover new galaxies but to use observations of them to investigate how dark energy’s influence has changed over the course of the universe’s history.

In particular, scientists want to know how much the rate of expansion has increased or slowed down over time. Whatever the answer, that information would provide new clues about the fundamental nature of this phenomenon. NASA’s Nancy Grace Roman Space Telescope, set to launch by 2027, will also observe large sections of the sky in order to study dark energy, complementing Euclid’s observations.

The locations of the Euclid deep fields are shown marked in yellow on this all-sky view from ESA’s Gaia and Planck missions. The bright horizontal band is the plane of our Milky Way galaxy. Of the two regions highlighted at bottom right, Euclid’s Deep Field South is the one at left.ESA/Euclid/Euclid Consortium/NASA; ESA/Gaia/DPAC; ESA/Planck Collaboration Looking Back in Time

To study dark energy’s effect throughout cosmic history, astronomers will use Euclid to create detailed, 3D maps of all the stuff in the universe. With those maps, they want to measure how quickly dark energy is causing galaxies and big clumps of matter to move away from one another. They also want to measure that rate of expansion at different points in the past. This is possible because light from distant objects takes time to travel across space. When astronomers look at distant galaxies, they see what those objects looked like in the past.

For example, an object 100 light-years away looks the way it did 100 years ago. It’s like receiving a letter that took 100 years to be delivered and thus contains information from when it was written. By creating a map of objects at a range of distances, scientists can see how the universe has changed over time, including how dark energy’s influence may have varied.

But stars, galaxies, and all the “normal” matter that emits and reflects light is only about one-fifth of all the matter in the universe. The rest is called “dark matter” — a material that neither emits nor reflects light. To measure dark energy’s influence on the universe, astronomers need to include dark matter in their maps.  

Bending and Warping

Although dark matter is invisible, its influence can be measured through something called gravitational lensing. The mass of both normal and dark matter creates curves in space, and light traveling toward Earth bends or warps as it encounters those curves. In fact, the light from a distant galaxy can bend so much that it forms an arc, a full circle (called an Einstein ring), or even multiple images of the same galaxy, almost as though the light has passed through a glass lens.

In most cases, gravitational lensing warps the apparent shape of a galaxy so subtly that researchers need special tools and computer software to see it. Spotting those subtle changes across billions of galaxies enables scientists to do two things: create a detailed map of the presence of dark matter and observe how dark energy influenced it over cosmic history.

It is only with a very large sample of galaxies that researchers can be confident they are seeing the effects of dark matter. The newly released Euclid data covers 63 square degrees of the sky, an area equivalent to an array of 300 full Moons. To date, Euclid has observed about 2,000 square degrees, which is approximately 14% of its total survey area of 14,000 square degrees. By the end of its mission, Euclid will have observed a third of the entire sky.

The dataset released this month is described in several preprint papers available today. The mission’s first cosmology data will be released in October 2026. Data accumulated over additional, multiple passes of the deep field locations will also be included in the 2026 release.

More About Euclid

Euclid is a European mission, built and operated by ESA, with contributions from NASA. The Euclid Consortium — consisting of more than 2,000 scientists from 300 institutes in 15 European countries, the United States, Canada, and Japan — is responsible for providing the scientific instruments and scientific data analysis. ESA selected Thales Alenia Space as prime contractor for the construction of the satellite and its service module, with Airbus Defence and Space chosen to develop the payload module, including the telescope. Euclid is a medium-class mission in ESA’s Cosmic Vision Programme.

Three NASA-supported science teams contribute to the Euclid mission. In addition to designing and fabricating the sensor-chip electronics for Euclid’s Near Infrared Spectrometer and Photometer (NISP) instrument, JPL led the procurement and delivery of the NISP detectors as well. Those detectors, along with the sensor chip electronics, were tested at NASA’s Detector Characterization Lab at Goddard Space Flight Center in Greenbelt, Maryland. The Euclid NASA Science Center at IPAC (ENSCI), at Caltech in Pasadena, California, supports U.S.-based science investigations, and science data is archived at the NASA / IPAC Infrared Science Archive (IRSA). JPL is a division of Caltech.

Goodnight, Moon: NASA Cameras on Blue Ghost Capture Lunar Sunset

NASA - Breaking News - Wed, 03/19/2025 - 9:00am
NASA/Olivia Tyrrell

This compressed, resolution-limited gif shows the view of lunar sunset from one of the six Stereo Cameras for Lunar-Plume Surface Studies (SCALPSS) 1.1 cameras on Firefly’s Blue Ghost lander, which operated on the Moon’s surface for a little more than 14 days and stopped, as anticipated, a few hours into lunar night. SCALPSS was taking images every 10 minutes during the sunset. The bright, swirly light moving across the surface on the top right of the image is sunlight reflecting off the lander. Images taken by SCALPSS 1.1 during Blue Ghost’s descent and landing, as well as images from the surface during the long lunar day, will help researchers better understand the effects of a lander’s engine plumes on the lunar soil, or regolith. The instrument collected almost 9000 images and returned 10 GB of data. This data is important as trips to the Moon increase and the number of payloads touching down in proximity to one another grows. The SCALPSS 1.1 project is funded by the Space Technology Mission Directorate’s Game Changing Development program. SCALPSS was developed at NASA’s Langley Research Center in Hampton, Virginia, with support from Marshall Space Flight Center in Huntsville, Alabama.

Euclid is back – 26 million galaxies and counting

ESO Top News - Wed, 03/19/2025 - 7:00am
Video: 00:06:44

The European Space Agency’s Euclid mission has scouted out the three areas in the sky where it will eventually provide the deepest observations of its mission.

In just one week of observations, with one scan of each region so far, Euclid already spotted 26 million galaxies. The farthest of those are up to 10.5 billion light-years away.

In the coming years, Euclid will pass over these three regions tens of times, capturing many more faraway galaxies, making these fields truly ‘deep’ by the end of the nominal mission in 2030.

The first glimpse of 63 square degrees of the sky, the equivalent area of more than 300 times the full Moon, already gives an impressive preview of the scale of Euclid’s grand cosmic atlas when the mission is complete. This atlas will cover one-third of the entire sky – 14 000 square degrees – in this high-quality detail.

Sols 4481-4483: Humber Pie

Curiosity Navigation

Sols 4481-4483: Humber Pie NASA’s Mars rover Curiosity acquired this image using its Front Hazard Avoidance Camera (Front Hazcam) on March 14, 2025 — sol 4480, or Martian day 4,480 of the Mars Science Laboratory mission — at 08:53:19 UTC.NASA/JPL-Caltech

Written by Michelle Minitti, Planetary Geologist at Framework

Earth planning date: Friday, March 14, 2025

The rover successfully arrived at the “Humber Park” outcrop which, on this fine “Pi Day” on Earth, we could convince ourselves looked like a pie with a sandy interior and a rough and rocky crust. We can only hope our instruments are as excited to tuck into this outcrop as the Curiosity team is to eat our pizzas and favorite pies (for me, pumpkin) this afternoon and evening. 

MAHLI gets a big serving of rock structures from the Humber Park “crust” with three separate imaging targets. One observation, at the target “Yerba Buena Ridge,” covers structures expressed across the front of the outcrop in the above image. A second target, “Sepulveda Pass,” has intriguing texture that warranted multiple flavors of stereo imaging. The final target, which MAHLI shared with APXS, was “South Fork.” It was the clearest place to put APXS down on the rough bedrock blocks. 

ChemCam also feasted on rock chemistry from an array of targets with different textures. “Ridge Route” covered a low-lying bedrock slab with the fine layering we have seen consistently through the sulfate unit, while “Toyon Canyon” covered a lumpier portion of the Humber Park outcrop above Yerba Buena Ridge. The “Mount Lawlor” target was a mix of Ridge Route and Toyon Canyon — layered, but on a high-standing portion of the outcrop that also had some unusual chains of pits. ChemCam added two long distance mosaics on “Gould Mesa” to the menu, which captured a variety of structures on this impressive butte about 100 meters ahead of the rover. 

Mastcam focused on covering the whole of Humber Park with a stereo mosaic but also added small mosaics across a trough in the sand and a bedrock block with potential cross bedding at “Rancho Los Feliz.” Because just imaging this side of Humber Park was not enough, Mastcam and Navcam worked closely with the rover drivers to plan a mid-drive mosaic of the other side of the outcrop so we fully capture Humber Park’s “crust.”

Our environmental observations were not just pie in the sky but will help us monitor the chemistry of and the amount of dust in the atmosphere, and record clouds and dust devils crossing above and around us.
