A team of technicians, engineers, sailors and divers just wrapped up a successful week of testing and preparing for various scenarios that could play out when NASA’s new Orion spacecraft splashes into the Pacific Ocean following its first space flight test in December. After enduring the extreme environment of space, Orion will blaze back through […]

Hubble Finds Supernova Star System Linked to Potential “Zombie Star”
Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint supernova may have left behind a surviving portion of […]
Hubble Shows Farthest Lensing Galaxy Yields Clues to Early Universe
Astronomers using NASA’s Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. These “lensing” galaxies are so massive that their gravity bends, magnifies, and distorts light […]
Cassini Spacecraft Reveals 101 Geysers and more on Icy Saturn Moon
Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface. These findings, and clues to what powers the geyser eruptions, are presented in two […]
NASA’s Hubble Helps Solve Mystery of Ultra-Compact, Burned-Out Galaxies
Astronomers using NASA’s Hubble Space Telescope and Europe’s Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe. Enabled by Hubble’s infrared imaging capabilities, astronomers have assembled for the first time a representative spectroscopic sampling of ultra-compact, burned-out elliptical galaxies […]
