How NASA’s SPHEREx Mission Will Share Its All-Sky Map With the World
NASA’s SPHEREx mission will map the entire sky in 102 different wavelengths, or colors, of infrared light. This image of the Vela Molecular Ridge was captured by SPHEREx and is part of the mission’s first ever public data release. The yellow patch on the right side of the image is a cloud of interstellar gas and dust that glows in some infrared colors due to radiation from nearby stars. NASA/JPL-Caltech NASA’s newest astrophysics space telescope launched in March on a mission to create an all-sky map of the universe. Now settled into low-Earth orbit, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) has begun delivering its sky survey data to a public archive on a weekly basis, allowing anyone to use the data to probe the secrets of the cosmos.
“Because we’re looking at everything in the whole sky, almost every area of astronomy can be addressed by SPHEREx data,” said Rachel Akeson, the lead for the SPHEREx Science Data Center at IPAC. IPAC is a science and data center for astrophysics and planetary science at Caltech in Pasadena, California.

Other missions, like NASA’s now-retired WISE (Wide-field Infrared Survey Explorer), have also mapped the entire sky. SPHEREx builds on this legacy by observing in 102 infrared wavelengths, compared to WISE’s four wavelength bands.
By putting the many wavelength bands of SPHEREx data together, scientists can identify the signatures of specific molecules with a technique known as spectroscopy. The mission’s science team will use this method to study the distribution of frozen water and organic molecules — the “building blocks of life” — in the Milky Way.

The telescope will observe every point in the sky in 102 different infrared wavelengths, more than any other all-sky survey.

Releasing SPHEREx data in a public archive encourages far more astronomical studies than the team could do on their own.
“By making the data public, we enable the whole astronomy community to use SPHEREx data to work on all these other areas of science,” Akeson said.
NASA is committed to the sharing of scientific data, promoting transparency and efficiency in scientific research. In line with this commitment, data from SPHEREx appears in the public archive within 60 days after the telescope collects each observation. The short delay allows the SPHEREx team to process the raw data to remove or flag artifacts, account for detector effects, and align the images to the correct astronomical coordinates.
The team publishes the procedures they used to process the data alongside the actual data products. “We want enough information in those files that people can do their own research,” Akeson said.
One of the early test images captured by NASA’s SPHEREx mission in April 2025. This image shows a section of sky in one infrared wavelength, or color, that is invisible to the human eye but is represented here in a visible color. This particular wavelength (3.29 microns) reveals a cloud of dust made of a molecule similar to soot or smoke. NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), once again represented by a color that is visible to the human eye. The dust cloud has vanished because the molecules that make up the dust — polycyclic aromatic hydrocarbons — do not radiate light in this color. NASA/JPL-Caltech
During its two-year prime mission, SPHEREx will survey the entire sky twice a year, creating four all-sky maps. After the mission reaches the one-year mark, the team plans to release a map of the whole sky at all 102 wavelengths.
In addition to the science enabled by SPHEREx itself, the telescope unlocks an even greater range of astronomical studies when paired with other missions. Data from SPHEREx can be used to identify interesting targets for further study by NASA’s James Webb Space Telescope, refine exoplanet parameters collected from NASA’s TESS (Transiting Exoplanet Survey Satellite), and study the properties of dark matter and dark energy along with ESA’s (European Space Agency’s) Euclid mission and NASA’s upcoming Nancy Grace Roman Space Telescope.
The SPHEREx mission’s all-sky survey will complement data from other NASA space telescopes. SPHEREx is illustrated second from the right. The other telescope illustrations are, from left to right: the Hubble Space Telescope, the retired Spitzer Space Telescope, the retired WISE/NEOWISE mission, the James Webb Space Telescope, and the upcoming Nancy Grace Roman Space Telescope. NASA/JPL-Caltech The IPAC archive that hosts SPHEREx data, IRSA (NASA/IPAC Infrared Science Archive), also hosts pointed observations and all-sky maps at a variety of wavelengths from previous missions. The large amount of data available through IRSA gives users a comprehensive view of the astronomical objects they want to study.
“SPHEREx is part of the entire legacy of NASA space surveys,” said IRSA Science Lead Vandana Desai. “People are going to use the data in all kinds of ways that we can’t imagine.”

Video Producer – Goddard Space Flight Center
What sparked your interest in video production, and what drew you to NASA?
Ever since I saw “Star Wars” at nine years old, I knew I wanted to make movies. I would make little stop action videos with my action figures.
How did you land this role at NASA, and what do your duties entail?
I was working with a company in New York for about eight years, producing a daily live interactive show on Facebook. I’ve always been obsessed with NASA, so when I saw the job opportunity I knew I had to take a shot. To this day I still can’t believe how lucky I am to work here. I’ve been working with the Hubble mission for the past five years, but I’ve begun to work on other missions like the James Webb Space Telescope, MAVEN (Mars Atmosphere and Volatile EvolutioN), Osiris-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer), and the incredible Nancy Grace Roman Space Telescope.
Paul Morris is a video producer at NASA’s Goddard Space Flight Center in Greenbelt, Md. His work brings the cosmos to the screen, turning space science into cinematic wonder.Credit: Courtesy of Paul Morris How has your style evolved over time?
My previous job was very steeped in “internet culture,” so it was a lot more fast-paced and crazy style videos. The main goal was to get the audience to watch past the ad break. With NASA I’ve been able to slow down my videos a bit more and focus more on quality and explaining the science result.
Paul has covered several NASA missions, including the James Webb, Hubble and upcoming Roman space telescopes. He translates scientific discoveries into exciting visual stories to connect broad audiences with NASA’s work.Credit: Courtesy of Paul Morris What guides your process when you start a new assignment?
Let me be clear, I feel that all astro science is super cool and interesting. However, some of it is less interesting to the general public. Therefore, the first thing I think about when approaching a potential new story is by asking the question: “Would a fifth grader think this story is awesome?” Black holes, giant explosions, stars dying…if the story is there then the imagery will be there too.
Part of Paul’s role as video producer involves interviewing scientists and other experts, drawing out insights that make complex topics more understandable.Credit: Courtesy of Paul Morris What’s been your favorite project so far?
A few years back, Hubble just celebrated the 30th anniversary of the first servicing mission, (the one that corrected the mirror flaw). I got to interview some of the biggest Hubble legends of all time and created a seven-part series from the perspectives of all of these genius engineers, scientists, and even astronauts. I was super proud of how all those videos came out.
Do you have any major goals you hope to achieve or projects you’d like to tackle someday?
I’d love to do a full-length movie following a project from its conception to its deactivation. Obviously, this is rather hard to do and will take years, potentially decades, but there are a few projects that are on the “ground floor” at the moment, so I’d love to just check in with them every year or so.
How has your work influenced your understanding or appreciation of space science and technology?
I’ve been absolutely obsessed with all things NASA since around third grade, so I’ve always loved space science and technology. However, I had no idea how much the technology of space telescopes has led to incredible advances in Earth technologies. From Olympic speed skating to breast cancer research or saving whale sharks, there’s just such a huge return on investment with NASA research.

The incredibly talented and creative people I work with always make me strive to make better videos.
What hobbies fill your time outside of work?
I’ve gotten really into running and CrossFit since Covid. I also direct plays from time to time at a local theatre near my house.
In addition to producing videos, Paul participates in outreach events to inform the public about NASA space missions.Credit: Courtesy of Paul Morris What advice do you have for others who are interested in doing similar work?
Always look for ways to add to your creative skillset. There are a lot of amazing training options available online, and there’s always something new you can do to make yourself even better than you are today.

Hubble Spies Paired Pinwheel on Its Own
This NASA Hubble Space Telescope image features the beautiful barred spiral galaxy NGC 3507 ESA/Hubble & NASA, D. Thilker A single member of a galaxy pair takes centerstage in this NASA/ESA Hubble Space Telescope image. This beautiful spiral galaxy is NGC 3507, which is situated about 46 million light-years away in the constellation Leo (the Lion). NGC 3507’s classification is a barred spiral because the galaxy’s sweeping spiral arms emerge from the ends of a central bar of stars rather than the central core of the galaxy.
Though pictured solo here, NGC 3507 actually travels the universe with a galactic partner named NGC 3501 that is located outside the frame. While NGC 3507 is a quintessential galactic pinwheel, its partner resembles a streak of quicksilver across the sky. Despite looking completely different, both are spiral galaxies, simply seen from different angles.
For galaxies that are just a few tens of millions of light-years away, like NGC 3507 and NGC 3501, features like spiral arms, dusty gas clouds, and brilliant star clusters are on full display. More distant galaxies appear less detailed. See if you can spot any faraway galaxies in this image: they tend to be orange or yellow and can be anywhere from circular and starlike to narrow and elongated, with hints of spiral arms. Astronomers use instruments called spectrometers to split the light from these distant galaxies to study the nature of these objects in the early universe.
In addition to these far-flung companions, a much nearer object joins NGC 3507. The object is marked by four spikes of light: a star within the Milky Way, a mere 436 light-years away from Earth.
