NASA's Hubble Captures Blistering Pitch-Black Planet

STScI-H-p1738a-f4500x3600.jpg

Astronomers using the Hubble Space Telescope have found that the well-studied exoplanet WASP-12b reflects almost no light and appears as black as fresh asphalt. Unlike other exoplanets in its class of hot Jupiters, it has the unique capability to trap at least 94 percent of the visible starlight falling into its super-heated atmosphere.

Hubble Detects Exoplanet with Glowing Water Atmosphere

Scientists have discovered the strongest evidence to date for a stratosphere on a planet outside our solar system. The exoplanet WASP-121b results obtained with the Hubble Space Telescope are published in the journal Nature.

NASA's Hubble Sees Martian Moon Orbiting the Red Planet

While photographing Mars, NASA's Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moon's orbital path.

Hubble Pushed Beyond Limits to Spot Clumps of New Stars in Distant Galaxy

By applying a new computational analysis to a galaxy magnified by a gravitational lens, astronomers have obtained images 10 times sharper than what Hubble could achieve on its own.

Hubble Captures Massive Dead Disk Galaxy That Challenges Theories of Galaxy Evolution

Astronomers combined the power of a “natural lens” in space with the capability of the Hubble Space Telescope to make a surprising discovery—the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang. Researchers say that finding such a galaxy so early in the history of the universe challenges the current understanding of how massive galaxies form and evolve.

Hubble Astronomers Develop a New Use for a Century-Old Relativity Experiment to Measure a White Dwarf's Mass

Astronomers have used the sharp vision of NASA’s Hubble Space Telescope to repeat a century-old test of Einstein’s general theory of relativity. The team measured the mass of white dwarf Stein 2051 B, the burned-out remnant of a normal star, by seeing how much it deflects the light from a background star. The gravitational microlensing method data provide a solid estimate of the white dwarf’s mass and yield insights into theories of the structure and composition of the burned-out star.

Jackpot! Cosmic Magnifying-Glass Effect Captures Universe's Brightest Galaxies

STSCI-H-p1724a-d-1280x720.png

Boosted by natural magnifying lenses in space, NASA's Hubble Space Telescope has captured unique close-up views of the universe's brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky Way. The results are being presented today at the American Astronomical Society meeting in Austin, Texas.

Mini-Flares Potentially Jeopardize Habitability of Planets Circling Red Dwarf Stars

STScI-H-p1723a-d932x720.png

Solar flares and associated eruptions can trigger auroras on Earth or, more ominously, damage satellites and power grids. Could flares on cool, red dwarf stars cause even more havoc to orbiting planets, even rendering them uninhabitable? To help answer that question, astronomers sought to find out how many flares such stars typically unleash.

Hubble's Tale of Two Exoplanets: Nature vs. Nurture

STSCI-H-p1722a-d890x720.png

Scientists using NASA's Hubble Space Telescope to study two "hot Jupiter" exoplanets--having virtually the same size and temperature, and orbiting around nearly identical stars at the same distance--hypothesized that the planets' atmospheres should be alike. But the researchers found that one planet's atmosphere was much cloudier than the other.

Collapsing Star Gives Birth to a Black Hole

Astronomers have watched as a massive, dying star was likely reborn as a black hole. It took the combined power of the Large Binocular Telescope (LBT), and NASA's Hubble and Spitzer space telescopes to go looking for remnants of the vanquished star, only to find that it disappeared out of sight.
