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...

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...

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

STSCI-H-p1726a-d-1280x720.png

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...

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...
