 In Unique Stellar Laboratory, Einstein's Theory Passes Strict, New Test


Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test.

 Spitzer Finds Evidence for Planets with Four Parents


How many stars does it take to "raise" a planet? In our own solar system, it took only one - our sun. However, new research from NASA's Spitzer Space Telescope shows that planets might be forming in systems with as many as four stars.

 A New Way to Weigh Giant Black Holes


How do you weigh the biggest black holes in the universe? One answer now comes from a completely new and independent technique that astronomers have developed using data from NASA's Chandra X-ray Observatory.

 Not a Quirk But a Quark ... a Quark Star!


Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.

NASA Scientists Pioneer Method for Making Giant Lunar Telescopes


Scientists working at NASA’s Goddard Space Flight Center in Greenbelt, Md., have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust.

Spitzer Finds Organics and Water Where New Planets May Grow


Researchers using NASA's Spitzer Space Telescope have discovered large amounts of simple organic gases and water vapor in a possible planet-forming region around an infant star, along with evidence that these molecules were created there. They've also found water in the same zone around two other young stars.
