Newly Announced Super-Earth May Be The Closest Exoplanet Discovered Yet

Gliese15Ab is a newly discovered planet roughly five times the mass of Earth. Researchers aren't sure what the planet's atmosphere is like, and it's close enough to its parent star to heat it past the boiling point of water. But the most interesting thing about Gliese 15Ab isn't how close it is to its star. It's how… » 8/29/14 9:45am Today 9:45am

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 Yesterday 9:20am

A Rare Chunk Of Giant Asteroid Vesta Has Been Stolen

Giant asteroid Vesta is the second-biggest object in our solar system's asteroid belt, and the origin of an estimated 5% of Earth's meteorites. Yesterday, an especially rare chunk of Vesta recovered from the Netherlands in 1925 was reported stolen from the Sonnenborgh Museum and Observatory in Utrecht, Netherlands. » 8/20/14 12:26pm 8/20/14 12:26pm

Weather Channel Reporter Won't Stop Mispronouncing This Moon's Name

Earlier this week, The Weather Channel's Matt Sampson hosted an interesting little news segment about violent volcanic activity recently detected on Jupiter's moon Io. But Sampson didn't call the planet by its name, which is pronounced "eye-oh." Instead, he – well, we don't want to spoil it. [Warning: Video Autoplays] » 8/10/14 4:30pm 8/10/14 4:30pm

Sunday Night Will Be An Extraordinary Time For Skygazing

The biggest, brightest full moon of 2014 rises this Sunday. That's exciting in and of itself (though not nearly as exciting as some headlines would suggest), but Sunday's "supermoon" also happens to coincide with the Perseid meteor shower, one of the largest and most dependable meteor displays of the year. » 8/08/14 1:00pm 8/08/14 1:00pm

The Aberration of Starlight Explains Why the Stars "Jump"

In the 1600s, astronomers noticed that the stars seemed to jump in a way that made no sense. During certain months, stars seemed to leap out of place through no phenomenon that they could understand. Then along came James Bradley, who used wind and rain to explain what he called the aberration of starlight. » 8/07/14 8:00am 8/07/14 8:00am

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

The Lady-Scientist Lego Set Is Now Available!

After much anticipation, and more than a little prodding, Lego has added three female researchers to its cadre of scientific minifigs. The "Reseach Institute" playset features an astronomer, a paleontologist and a chemist, and a range of badass accoutrements (like Lego dinosaur fossils!) specific to each specialty. » 8/02/14 11:00am 8/02/14 11:00am

Astronomers Happen Upon The Most Distant Lensing Galaxy Ever Discovered

Astronomers using the Hubble Space Telescope have spotted an elliptical galaxy 9.6-billion light years from Earth that is so colossal, its gravity bends and magnifies the light from a galaxy behind it. The rare alignment is the most distant example of a lensing galaxy ever discovered, and could yield insights into the… » 8/01/14 8:30am 8/01/14 8:30am

This Is Probably The Weirdest Binary Star System Ever Discovered

There's some strange things floating around in our galaxy, but this has to be one of the weirdest. A double star system with misaligned protoplanetary disks around 450 light-years from Earth has been discovered, potentially explaining why some exoplanet orbits can be wildly eccentric. » 7/31/14 4:40pm 7/31/14 4:40pm

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
