Help Refine Data from Space Telescopes with Artifact InSPECtor

2026-09-11 19:48

How do scientists studying space with data from a telescope hundreds of thousands of miles away know that what they are seeing is real? A new NASA project, Artifact InSPECtor, invites you to find out – and by doing so, to help missions like Euclid and NASA’s new Nancy Grace Roman Space Telescope answer fundamental questions about our universe.

“It’s really cool that we can help teach computers new skills,” said nine-year-old Maeve F. after trying out Artifact InSPECtor. Participants of all ages, including those as young as Maeve, can visit the project to learn how they can contribute to science by training artificial intelligence to remove errors in telescope data.

Here’s how it works.

The Euclid space telescope, a powerful observatory built by ESA (European Space Agency) with critical contributions from NASA, is collecting light from millions of distant galaxies across the universe. It will soon be joined by NASA’s Nancy Grace Roman Space Telescope, a complementary observatory that will capture a similar number of galaxies after it begins science operations, but at different distances and densities across the sky. Together, these telescopes promise to help scientists answer questions about the expansion of the universe and dark energy – the mysterious force causing this expansion.

To collect data to answer these questions, each telescope uses a special instrument called a spectrograph that works like a prism: it splits the light from each galaxy, even very distant ones, into a rainbow of colors. By studying these rainbow patterns, called spectra, scientists can figure out how far away each galaxy is, what kinds of stars it contains, and even information about the supermassive black holes at their centers.

But before that can happen, there’s a problem to solve.

Telescope data contains many “artifacts” – the general name scientists use for signals that come from things other than real astronomical objects like galaxies or stars. Artifacts can be created by light glinting off the telescope’s housing, cosmic rays striking the detector, quirks in the camera or electronics, or other sources. It’s a bit like when a smudge on your phone’s camera lens shows up in a photo, or when a glare from the Sun blocks part of your picture.

To find and remove these artifacts, astronomers have created artificial intelligence (AI) tools that learn to recognize them, similar to how your phone recognizes faces in photos. But recognizing artifacts in data from relatively new instruments is challenging work for the AI, which doesn’t always distinguish them accurately

That’s where you come in! As a volunteer with Artifact InSPECtor, you’ll look at real space telescope data from Euclid and, starting in early 2027, the Nancy Grace Roman Space Telescope. The project will teach you how to recognize artifacts in data from these telescopes. The work you do will then be used to improve the instructions guiding the AI tool. Working together, you, the AI, the scientists, and these powerful space telescopes will learn more than ever before about how our universe works.

If you want to teach computers new skills and help discover the mysteries of dark energy, use your smartphone, tablet, or computer to visit Artifact InSPECtor and begin today: https://go.nasa.gov/3Uyrguy.

NASA’s Chandra Spots Galactic Gem

2026-09-11 17:19

In this system, two galaxies are merging at a furious rate. Near the top of the image is a spiral galaxy shape with thick arms in fiery oranges, whites, and reds. At the bottom of the image is a faint hazy bowl shape marbled with grainy white ribbons and hot pink specks. Where the two shapes collide, in the center of the frame, the galaxy appears utterly chaotic, like a firework.

NASA Boosts Open Science, Data Sharing with Artemis Accords

2026-09-11 14:56

(April 6, 2026) – Poynting crater and Keeler crater are visible side by side in the lower right portion of this image of the Moon’s far side highlands. Poynting, positioned above, is a large impact crater with a well-defined rim and relatively smooth interior, indicative of material that has settled following the initial impact. Just below it, Keeler crater appears slightly smaller, with a sharply outlined rim and a more textured interior shaped by subsequent impacts and ejecta. Both features lie within the densely cratered far side highlands, preserving a record of ancient impacts that have shaped the lunar surface over billions of years.

The science from every Moon rock sample, lunar dataset, and discovery produced through NASA’s Artemis program will be shared by the agency with the global scientific community. That commitment is upheld by all 71 countries that have signed the Artemis Accords, a set of principles for safe and transparent civil space exploration.

NASA put those principles into practice by hosting a two-part virtual workshop series that began July 28 and concluded Sept. 8, focusing on one key tenet of the Artemis Accords: the timely release of scientific data to the public and the international scientific community.

“As we return humans to the Moon, our Artemis efforts will help us unlock the full potential of scientific discovery through transparency, collaboration, and accessibility,” said Jacob Bleacher, chief exploration scientist at NASA. “We are making data, tools, and results freely available, and inviting the Artemis Accords partners to innovate with us and share their data as well, accelerating our understanding of lunar processes and laying the groundwork for human space exploration for the Moon, Mars and beyond.”

The two recent workshops added to discussions led by the ISRO (Indian Space Research Organisation) in May, when signatories first explored ways to advance open data practices and created common ground for deeper conversations on open data. NASA split its follow‑on discussion about data sharing into two virtual sessions, so technical experts around the world could take part.

The agency hosted its first session on open science principles and implementation practices. It promoted interoperability and collaboration among signatories and advanced reproducibility, accessibility, and transparency in scientific work, including in NASA’s Artemis program.

The second session focused on tools for open science, providing Artemis Accords signatories with a working model to reference as they build or refine their own data-sharing frameworks.

“NASA is committed to leading by example when it comes to open science,” said Andrew Mitchell, deputy chief science data officer for NASA’s Science Mission Directorate, whose office leads the agency’s open science efforts. “These workshops gave our Artemis Accords partners practical tools and a shared foundation to build on as we move forward together.”

NASA presented the Planetary Data System, one of the agency’s primary archives for planetary science data, openly available lunar data, data visualization and analysis tools, and the system’s data information model standard, offering a real-world example of how NASA structures, curates, and shares scientific data with the world.

Across both sessions, NASA shared practices developed over years of stewarding scientific data and opened the floor to technical experts across the Artemis Accords community, reflecting a deliberate effort to build alignment at the working level.

“Advances in technology help enable open science, but technology alone is insufficient,” said Mitchell. “Open science requires a shift to a more transparent and collaborative scientific process, which will increase the pace and quality of scientific progress. Scientific processes and results should be as open and repeatable as possible to encourage further study.”

In 2020, NASA and the State Department joined with seven other founding nations to establish the Artemis Accords in response to the growing interest in lunar activities by both governments and private companies. They introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond, committing nations to:

explore peaceably and transparently
render aid to those in need
enable access to scientific data
ensure activities do not interfere with those of others
preserve historically significant sites and artifacts by developing best practices

By signing the Artemis Accords, nations open the door to opportunities for future lunar exploration with NASA, advancing humanity’s return to the Moon, and shaping the Golden Age of space exploration and innovation.

APOD: 2026 September 11 – M83: The Southern Pinwheel

2026-09-11 04:05

APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A spiral galaxy is shown in front of a dark field of stars.

M83: The Southern Pinwheel

Explanation: Beautiful and bright spiral galaxy M83 lies some twelve million light-years away, near the southeastern tip of the very long constellation Hydra. Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name, the Southern Pinwheel. Still, reddish star forming regions that dot this cosmic pinwheel’s spiral arms have suggested another nickname, the Thousand-Ruby Galaxy. A mere 40,000 light-years across, smaller than the Milky Way, M83 is a member of a group of galaxies that includes active galaxy Centaurus A. In fact, the core of M83 itself is bright at x-ray energies, showing a high concentration of neutron stars and black holes left from an intense burst of star formation. This sharp, groundbased telescopic view also features foreground Milky Way stars and distant background galaxies.
