This Dying Star Is The Center Of The Coldest Place In The Universe

Until NASA's Cold Lab comes online in 2016, the coldest place in the universe is a faint scattering of gas and dust 5,000 light years away in the Centaurus constellation. The Boomerang Nebula is just 1 degree above absolute zero, colder than the natural background temperature of space. » 12/18/14 5:02pm Thursday 5:02pm

Yes, Time Travel Is Possible; Here's How

Time travel's been one of man's wildest fantasies for centuries. It's long been a popular trend in movies and fiction, inspiring everything from Charles Dickens' A Christmas Carol to H.G. Wells' The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar » 11/05/14 6:28pm 11/05/14 6:28pm

What Lit Up The Universe? Astronomers May Be On The Brink Of An Answer

Most scientists can see, hear, smell, touch or even taste their research. But astronomers can only study light — photons traveling billions of light-years across the cosmos before getting scooped up by an array of radio dishes or a single parabolic mirror orbiting the Earth. » 8/28/14 9:20am 8/28/14 9:20am

First Close-Up Photos Of The Solar System's "Most Crazy Bonkers Comet"

In March 2004, ESA's Rosetta spacecraft left Earth in pursuit of comet 67P/Churyumov-Gerasimenko. Today, more than 10 years and four billion miles later, Rosetta became the first spacecraft in history to rendezvous with a comet. The probe is now soaring through space in tandem with its target – and the view is… » 8/06/14 9:50am 8/06/14 9:50am

Here's Our Best Look Yet At Rosetta's "Rubber Ducky" Comet

The Rosetta spacecraft has been chasing comet 67P/Churyumov-Gerasimenko for more than a decade. Now, with arrival less than a week away, the distance between the spacecraft and its quarry is rapidly shrinking. Meanwhile, Rosetta continues to return clearer and clearer images of the double-lobed "rubber ducky comet." » 7/31/14 9:15am 7/31/14 9:15am

Venus Has Space Weather Explosions That Are Larger Than the Planet

A common space weather phenomenon on the outskirts of the magnetosphere, the magnetic bubble that surrounds the earth (and protects the surface of the planet from solar radiation) are "hot flow anomalies." These are, in effect, enormous explosions. NASA researchers recently discovered that the same phenomenon occurs… » 6/08/14 10:40am 6/08/14 10:40am
