NASA’s Kepler Mission Discovers a World Orbiting Two Stars


The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA's Kepler mission has made the first unambiguous detection of a circumbinary planet -- a planet orbiting two stars -- 200 light-years from Earth.

Unlike Star Wars’ Tatooine, the planet is cold, …

Herschel Mission Finds Galactic Growth Slow and Steady




The Herschel Infrared Space Observatory discovered that galaxies do not always need to collide with each other to drive vigorous star birth. The finding overturns a long-held assumption and paints a more stately picture of how galaxies evolve. The new results are based on Herschel's …

New Supernova Remnant Lights Up




Using the Hubble Space Telescope, astronomers are witnessing the unprecedented transition of a supernova to a supernova remnant, where light from an exploding star in a neighboring galaxy, the Large Magellanic Cloud, reached Earth in February 1987. Named Supernova 1987A, it was the closest supernova explosion …

Violent Storms Rage on Nearby Brown Dwarf



Forget hurricane Irene that hammered the U.S. East Coast last month. You can even forget the monster storm whirling endlessly on Jupiter, creating the famous Great Red Spot. If celestial objects could compare storm violence, a nearby brown dwarf would win easily -- and its effects can be detected 47 …

Batch of Fifty New Alien Worlds Discovered



Astronomers have announced the discovery of 50 (yes, five-zero) exoplanets, the largest group of alien worlds announced at one time.
Sixteen of these worlds are "super-Earths" -- exoplanets that possess masses larger than Earth, yet much lower than the gas giants.

This time, however, the …

RADIO-ALTERING FLARE
Tue Sep 06, 2011 12:34 am by AstroJunkie
On Sunday morning at 1145 UT, an active region on the sun's western limb unleashed a strong M3-class solar flare.



Although the blast site was not directly facing Earth, radiation from the explosion nevertheless ionized Earth's upper atmosphere. This altered the propagation of radio signals around Europe, where it was high-noon at the time of the flare. "I …
