NASA’s Fermi Mission Uncovers Possible Sibling Supernova Remnants
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star’s detonation sent its binary companion hurtling through space, and then, after…

NASA Webb, Hubble Reveal History of Relic of Milky Way’s Formation
Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies…

NASA’s Fermi Glimpses Power Source of Supercharged Supernovae
An international team studying data from NASA’s Fermi Gamma-ray Space Telescope concludes the mission detected a rare, unusually luminous supernova. The researchers say it likely received its power-up from a supermagnetized neutron star born in the stellar collapse that triggered…

Hubble Survey Sets Up Roman’s Future Look Near Milky Way’s Center
The Milky Way’s galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA’s Hubble…

NASA’s Hubble Dazzles With Young Stars in Trifid Nebula
This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope. The colors in Hubble’s visible light image, which marks the 36th anniversary of the…

NASA Finds Young Stars Dim in X-rays Surprisingly Quickly
Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published…

NASA’s Webb Telescope Locates Former Star That Exploded as Supernova
Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, 2025, where it was detected by the All-Sky…

TESS Status Updates
Jan. 23, 2026 NASA’s TESS Returns to Science Observations NASA’s TESS (Transiting Exoplanet Survey Satellite) entered safe mode Jan. 15 and returned to normal science operations Jan. 18. The operations team determined the issue arose when TESS slewed to point…

NASA Webb Finds Young Sun-Like Star Forging, Spewing Common Crystals
Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper…

Hubble Snaps Stellar Baby Pictures
Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form. Protostars are shrouded in thick…
