    NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

    A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it…

    NASA’s Hubble Unexpectedly Catches Comet Breaking Up

    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…

  • Two Observatories, One Cosmic Eye: Hubble and Euclid View Cat’s Eye Nebula

    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…

  • NASA’s Hubble Identifies One of Darkest Known Galaxies

    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…

  • NASA’s Hubble Captures Light Show Around Rapidly Dying Star

    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…

  • Hubble Sees Galaxy with Dark Rings in New Light

    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…

    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…

  • NASA Hubble Helps Detect ‘Wake’ of Betelgeuse’s Elusive Companion Star

    NASA Hubble Helps Detect ‘Wake’ of Betelgeuse’s Elusive Companion Star

    Using new observations from NASA’s Hubble Space Telescope and ground-based observatories, astronomers tracked the influence of a recently discovered companion star, Siwarha, on the gas around Betelgeuse. The research, from scientists at the Center for Astrophysics | Harvard & Smithsonian…

  • NASA’s Hubble Examines Cloud-9, First of New Type of Object

    NASA’s Hubble Examines Cloud-9, First of New Type of Object

    A team using NASA’s Hubble Space Telescope has uncovered a new type of astronomical object — a starless, gas-rich, dark-matter cloud considered a “relic” or remnant of early galaxy formation. Nicknamed “Cloud-9,” this is the first confirmed detection of such…

  • NASA’s Hubble Reveals Largest Found Chaotic Birthplace of Planets

    NASA’s Hubble Reveals Largest Found Chaotic Birthplace of Planets

    Astronomers using NASA’s Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, Hubble has revealed the disk is unexpectedly chaotic and turbulent, with wisps of material stretching…
