Space Telescope Science Institute Celebrates Its 40th Anniversary

Forty years ago in 1981, the first space shuttle launched, the Voyager 2 space probe encountered Saturn, and in Baltimore, Maryland, the Space Telescope Science Institute (STScI) was founded. In that year, NASA selected a proposal by the Association of Universities for Research in Astronomy to establish STScI on the Johns Hopkins University Homewood...

Hubble Spots Double Quasars in Merging Galaxies

Inhabitants of our Milky Way galaxy living several billion years from now will have a markedly different-looking sky overhead. Two brilliant objects, each as bright as the full Moon or brighter, will drown out the stars with their radiance. These giant blazing light bulbs are a pair of quasars, brought to life by the collision of our Milky Way with...

Hubble Shows Torrential Outflows from Infant Stars May Not Stop Them from Growing

Stars aren't shy about announcing their births. As they are born from the collapse of giant clouds of hydrogen gas and begin to grow, they launch hurricane-like winds and spinning, lawn-sprinkler-style jets shooting off in opposite directions. This action carves out huge cavities in the giant gas clouds. Astronomers thought these stellar temper...

NASA Hubble Space Telescope's Wide Field Camera 3 Restored

The Wide Field Camera 3 (WFC3) instrument on NASA's Hubble Space Telescope was brought back online on Saturday, March 13th at approximately 7:00 p.m. EST. The instrument was shut down as part of the normal observatory safe mode activities that occurred on Sunday, March 7, in response to a software error on the main flight computer. After starting its...

NASA’s Hubble Space Telescope Set to Resume Science Operations

NASA is working to return the Hubble Space Telescope to science operations after resolving a problem with a safeguard aboard. Hubble entered safe mode on Sunday, March 7, shortly after 4 a.m. EST, following detection of a software error within the spacecraft’s main computer. The spacecraft has been moved out of safe mode into a pre-science state with...

Distant Planet May Be On Its Second Atmosphere, NASA's Hubble Finds

Orbiting a red dwarf star 41 light-years away is an Earth-sized, rocky exoplanet called GJ 1132 b. In some ways, GJ 1132 b has intriguing parallels to Earth, but in other ways it is very different. One of the differences is that its smoggy, hazy atmosphere contains a toxic mix of hydrogen, methane and hydrogen cyanide. Scientists using NASA's Hubble...

Hubble Solves Mystery of Monster Star's Dimming

Stars come in an extraordinary range of sizes. One of the most colossal is VY Canis Majoris. If placed in the middle of our solar system it would engulf all the planets out to Saturn's orbit. This monster, appropriately called a red hypergiant, is as bright as 300,000 Suns. Yet it is so far away that, 200 years ago, it could be seen only as a faint...
