 A Scan Of 100,000 Galaxies Shows No Sign Of Alien Mega-Civilizations

A pioneering infrared scan of 100,000 galaxies by Penn State astronomers has failed to detect any signs of galaxy-spanning extraterrestrial supercivilizations. This result, though very preliminary, may be a sign that aliens aren't capable of conquering entire galaxies. » 4/15/15 1:17pm 4/15/15 1:17pm

Astrophysicists Find That Cities Grow Just Like Galaxies 

We've all looked out at the night sky and wondered at how much the stars look like strings of cities. But there's more than a passing resemblance—according to a team of astrophysicists who compared the two, there's a much deeper connection at work. We aren't just made of stars, we act like them too. » 1/20/15 9:42am 1/20/15 9:42am

Here Are Two Galaxies With Supermassive Black Hole Hearts Colliding

Hey there, human, want to feel some awe? Look at this newly released NASA image set of two galaxies, each with a supermassive black hole at its heart, colliding in a violent spiral of star stuff. Space is awesome, and thanks to improved telescope technology, we're seeing more and more of it every day. » 1/09/15 11:15am 1/09/15 11:15am

New map shows where the Milky Way galaxy is inside its supercluster

For the first time, scientists have pinpointed where our galaxy stands amongst thousands of other galaxies in our home supercluster. The new map shows beautiful feathery strings linked together with the Milky Way galaxy placed on the edge of the newly named Laniakea supercluster, home to 100,000 other galaxies. » 9/03/14 6:36pm 9/03/14 6:36pm

Astronomers Invent New Telescope by Tying Telephoto Lenses Together

A team of Yale astronomers got a little crafty recently. In an attempt to see parts of space that their big fancy telescopes weren't showing them, they tied eight telephoto lenses together to create their own little homemade array. And then, thanks to their new invention, they quickly discovered seven new galaxies. » 7/14/14 11:27am 7/14/14 11:27am

Science Just Made the Most Massive, In-Depth Universe Simulation Ever

Ever wanted to see what our universe looked like moments after the Big Bang? Good luck—it would take your desktop computer more than 2,000 years to complete. Luckily, researchers just published findings from the first ultra-realistic simulation of our universe's growth. And it covers 13 billion years. » 5/07/14 5:20pm 5/07/14 5:20pm

These Stars May Look Mellow But They're Resisting A Huge Black Hole

Nothing is ever as tranquil as it seems. This image is pretty and has lots of fun, trippy colors. But all of that variation is being produced by gas, dust and other matter as whole galaxies fall into a supermassive black hole. Created from Hubble data, the image shows the cosmic tug-of-war going on in the Perseus… » 10/13/13 4:53pm 10/13/13 4:53pm

Millions Of Stars In Motion Make Glorious Intergalactic Collisions

Collisions happen on different scales. Particles collide. Squirrels accidentally run into each other. Rams butt heads. Tectonic plates shift against each other. There's a lot going on. But in this photo a dwarf galaxy and spiral galaxy are smooshing into each other. And galaxies are kind of huge. » 8/18/13 6:55pm 8/18/13 6:55pm
