2 Newfound Alien Planets May Be Capable Of Supporting Life
NASA's Kepler space telescope has spotted four possibly rocky alien planets orbiting the same star, and two of these newfound worlds might be capable of supporting life. One is likely 10 percent warme...
LIGO: Journey of a Gravitational Wave
LIGO scientist David Reitze takes us on a 1.3 billion year journey that begins with the violent merger of two black holes in the distant universe. The event produced gravitational waves, tiny ripples...
Gravitational Waves Are Real But What Are They?
Scientists at the advanced Laser Interferometer Gravitational-Wave Observatory facilities found definitive proof of Einstein's prediction about gravitational waves. Brian Greene explains to Stephen Co...
Here's How It Felt to Discover Gravitational Waves
Three LIGO scientists who discovered gravitational waves talk about their amazing discovery and the future of gravitational wave astronomy.
Ripples in the fabric of space have been discovered
Scientists just detected ripples in the fabric of space created by colliding black holes — and science will never be the same.
Gravitational Wave Detection Might Be Announced Feb. 11
Gravitational waves may have been detected for the first time, but we won't know for sure until February 11, 2016 — when scientists will either confirm or dispel the rumors, sources close to the matte...
After 100 Years, Scientists Are Finally Closing In On Einstein’s Ripples
The rain began to fall as Joe Giaime and I scrambled down a lonely rise, back toward the observatory’s main building. It wasn’t so much rain as a hard mist, characteristic of the muggy weather souther...
Why is this famous physicist tweeting rumors about gravitational waves?
The detection of gravitational waves would be huge, but let's not get too excited.
Scientists Struggle To Stay Grounded After Possible Gravitational Wave Signal
Not for the first time, the world of physics is abuzz with rumours that gravitational waves have been detected by scientists in the US. Lawrence Krauss, a cosmologist at Arizona State university, twee...
Spacecraft That Will Test Einstein Theory Ready For Lift-Off
A spacecraft designed to test Albert Einstein's Theory of General Relativity is set to launch on Dec. 2. Under the eLISA Mission, LISA Pathfinder will help scientists detect presence of gravitational ...
Weird star: Strange dips in brightness are a bit baffling.
A paper by a team of astronomers is getting some notice because of aliens. Now let’s have a care here. The paper doesn’t mention aliens, and it doesn’t even imply aliens. Not directly, at least. But t...
Sign Of Alien Life? Kepler Telescope Spots Strange Star
A distant star is getting a lot of attention from astronomers — possibly as a sign that alien life is out there. The star KIC 8462852 was discovered through Planet Hunters, a citizen science program a...
Kepler Mission Discovered A Kepler 452b
A planet that closely resembles Earth is 1,400 light years away from us. This has just been recently discovered by NASA’s Kepler Mission, a discovery probe that seeks to find other planets with Earth-...
Rotating ellipsoidal variable
Rotating ellipsoidal variables are a class of variable star. They are close binary systems whose components are ellipsoidal. They are not eclipsing, but fluctuations in apparent magnitude occur due ...
RS Canum Venaticorum variable
RS Canum Venaticorum variables are a type of variable star. They are close binary stars having active chromospheres which can cause large stellar spots. These spots are believed to cause variations in...
X-ray binary
X-ray binaries are a class of binary stars that are luminous in X-rays. The X-rays are produced by matter falling from one component, called the donor (usually a relatively normal star), to the other ...
Beta Lyrae variable
Beta Lyrae variables are a class of close binary stars. Their total brightness is variable because the two component stars orbit each other, and in this orbit one component periodically passes in fron...
W Ursae Majoris variable
A W Ursae Majoris variable, also known as a low mass contact binary, is a type of eclipsing binary variable star. These stars are close binaries of spectral types F, G, or K that share a common envelo...
Beta Draconis
Beta Draconis (β Draconis, β Dra) is the third brightest star in the northern circumpolar constellation of Draco. It has the traditional name Rastaban, which has also been used for Gamma Draconis. Wi...
Mu Velorum
Mu Velorum (μ Vel, μ Velorum) is a binary star system in the southern constellation Vela. The two stars orbit each other with a semi-major axis of 1.437 arcseconds and a period of 116.24 yea...
