For the first time, a young, Sun-like star has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star in this image released on Feb. 23, 2026. Winds from the star’s surface are blowing up the bubble and […]

Young ‘Sun’ Caught Blowing Bubbles by NASA’s Chandra
For the first time, a much younger version of the Sun has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas […]
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 Automated Survey for Supernovae. Astronomers immediately turned their resources to this new supernova, designated 2025pht, […]
Journey to Center of Milky Way With Upcoming NASA Roman Core Survey
At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets, and unique objects that resist definition. Based on the input of astronomers from across the […]
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 at a target, but its solar panels did not rotate to remain pointed at the […]
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 Belt and Oort Cloud. Now, looking outside our solar system, NASA’s James Webb Space Telescope […]
Hubble Nets Menagerie of Young Stellar Objects
A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula. Two dark stripes on opposite sides of […]
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 dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes […]

Hubble Observes Ghostly Cloud Alive with Star Formation
While this eerie NASA Hubble Space Telescope image may look ghostly, it’s actually full of new life. Lupus 3 is a star-forming cloud about 500 light-years away in the constellation Scorpius. White wisps of gas swirl throughout the region, and in the lower-left corner resides a dark dust cloud. Bright T Tauri stars shine at […]
