In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]

Telescopes Team Up for New View of Cat’s Eye Nebula
This March 3, 2026, image combines views from ESA’s (European Space Agency) Euclid and NASA’s Hubble Space Telescope to feature one of the most visually intricate remnants of a dying star: the Cat’s Eye Nebula, also known as NGC 6543. This extraordinary planetary nebula lies 4,400 light-years away in the constellation Draco and has captivated astronomers for decades […]
NASA Discovers Crash of Extreme Stars in Unexpected Site
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before — and it may help solve two outstanding cosmic mysteries. A paper describing these results […]
Two Observatories, One Cosmic Eye: Hubble and Euclid View Cat’s Eye Nebula
This new NASA/ESA Hubble Space Telescope image features one of the most visually intricate remnants of a dying star: the Cat’s Eye Nebula, also known as NGC 6543. This extraordinary planetary nebula lies in the constellation Draco and has captivated astronomers for decades with its elaborate and multilayered structure. Observations with ESA’s Gaia mission place the nebula at 4,400 light-years away. […]
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 Hubble Identifies One of Darkest Known Galaxies
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible — low-surface-brightness galaxies dominated by dark matter and containing only a sparse scattering of faint stars. One such elusive object, dubbed CDG-2, may be among the most heavily dark matter-dominated […]
NASA’s Hubble Captures Light Show Around Rapidly Dying Star
This stunning image from NASA’s Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust — like a “yolk” nestled within a […]
Hubble Sees Galaxy with Dark Rings in New Light
This NASA/ESA Hubble Space Telescope image features an uncommon galaxy with a striking appearance. NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies. It is also less common than spirals and ellipticals — partly because […]

AI Unlocks Hundreds of Cosmic Anomalies in Hubble Archive
A team of astronomers has employed a cutting-edge, artificial intelligence-assisted technique to uncover rare astronomical phenomena within archived data from NASA’s Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side. They identified more than […]
