Astronomers report the discovery of the first known early-type magnetic star in an eclipsing binary system. The finding, detailed in a paper published April 27 on the arXiv pre-print server, could have important implications ...
In its search for extrasolar planets, the Kepler space telescope looks for stars whose light flux periodically dims, signaling the passing of an orbiting planet in front of the star. But the timing and duration of diminished ...

(Phys.org)—A new magnetic cataclysmic variable (CV) star has been detected by astronomers in the constellation of Draco. The newly found object, designated DDE 32, exhibits a large amplitude variability with one of the ...
NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface.
