    Astronomers celebrating Hubble’s past focus on its future

    BALTIMORE — A technique for sniffing around in the atmospheres of supersized planets near super bright stars could also help the Hubble Space Telescope unravel the history of the universe.

    Hubble scientists developed a way to slowly scan the sky while collecting starlight so the telescope could explore the neighborhoods of stars that would otherwise be too bright for its sensitive...

    Celebrating 25 years of the Hubble Space Telescope

    View slideshow • View video

    On a chilly Saturday evening in March, unfazed by more than 6 inches of new snow, hundreds of people crowded into Shriver Hall at Johns Hopkins University in Baltimore to hear the East Coast premiere of “Cosmic Dust,” an orchestral piece set to images of deep space. A trumpet fanfare conveyed the immense power of an exploding star; a cascade from the violins...

    The art of astronomy

    An astronomer by training but a photographer at heart, Zoltan Levay creates images of the cosmos with one of humankind’s most advanced optical instruments: the Hubble Space Telescope. Producing photos with the telescope, he says, is not that different from shooting mountains and rivers in national parks. “We’re just shooting landscapes of the universe instead,” he says...

    Aurora shift confirms Ganymede’s ocean

    Jupiter’s largest moon, Ganymede, has solidified its membership in the growing cadre of solar system locales where liquid water flows beneath the surface.

    “The solar system is now looking like a pretty soggy place,” Jim Green, director of NASA’s Planetary Science Division, said March 12 at a news conference.

    The ocean showed itself not with plumes or pools but via subtle changes in...

    Supernova hurls star out of the galaxy

    Some stars are in a rush to get out of the galaxy. One such star is hurtling away from the Milky Way at roughly 4.3 million kilometers per hour, researchers report in the March 6 Science, making it the fastest-moving star to be ejected from our galaxy.

    The escapee, designated US 708, might have been propelled by a stellar explosion known as a type 1a supernova, suggest Stephan Geier, an...

    Hubble telescope sees quadruple

    The Hubble Space Telescope is seeing quadruple. Four images of the same supernova flashed in the constellation Leo as its light bent around a galaxy sitting about 6 billion light-years away between Hubble and the exploding star, researchers report in the March 6 Science.

    The light from the supernova, nicknamed Refsdal, traveled for over 9 billion years along paths dictated by the gravity...

    Hubble telescope captures panorama of Andromeda galaxy

    SEATTLE — The Andromeda galaxy is ready for its close-up.

    The closest spiral galaxy to the Milky Way appears in unprecedented detail in a new mosaic of images from the Hubble Space Telescope presented January 5 at the American Astronomical Society meeting. The final composite is a 61,000-light-year-long panorama of our galactic neighbor encompassing the light of nearly 117 million stars...

    Hubble telescope snaps new images of iconic stellar nursery

    The Hubble Space Telescope's new view of the Pillars of Creation, a star-forming region in the Milky Way, is giving scientists a close look at how this iconic cosmic structure has changed over time.

    Astronomers first used Hubble to snap detailed images of the pillars, which are part of the Eagle Nebula, in 1995. The nebula is 7,000 light-years from Earth in the constellation Serpens. Now...

    Hubble telescope spots our galaxy's newest neighbor

    The Milky Way galaxy has a new neighbor. The newcomer, called Kks3, is a tiny, isolated dwarf galaxy that sits almost 7 million light-years away in the constellation Hydrus. It's low on the gas and dust needed to make new stars. But unlike other dwarfs like it, Kks3 doesn't have a big companion galaxy stripping away those raw star-making materials. That may mean that there's another way to...

    Second stop planned for mission to Pluto

    Guest post by Christopher Crockett

    NASA’s New Horizons mission may have somewhere to go after flying by Pluto next summer. Mission scientists using the Hubble Space Telescope have finally identified three possible destinations within the Kuiper belt, the ring of icy debris that lies beyond the orbit of Neptune.

    The most promising target is a boulder of ice about 55 kilometers...
