The 5 Massive New Telescopes That Will Change Astronomy Forever

The biggest building boom in the history of astronomy is upon us. In Chile and Hawaii and in space, astronomers are getting powerful telescopes that dwarf the current state-of-the-art instruments. When the mountain blasting and the mirror polishing are all done, we will have the clearest and most detailed views of… » 7/25/14 9:00am Yesterday 9:00am

How to Turn An Old Satellite Dish Into a Working Radio Telescope

Radio telescopes, which you may remember Jodie Foster intently listening to for signs of alien life in Contact, pluck out radio waves from far away space. Ordinary communications satellite dishes also pick up radio waves, but of manmade origin. So hmm, how easily can you convert one into another? It's totally… » 7/23/14 4:21pm Wednesday 4:21pm

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

Tonight's Supermoon Will Be Almost as Glorious as Next Month's

Have you heard? There's gonna be a Supermoon tonight! It's a very cool sight to see, especially on a clear night. But it's way more common than you might think. In fact, the next three full moons this summer will be Supermoons. And astronomers are kind of puzzled as to why we seem to only notice them at random. » 7/12/14 11:00am 7/12/14 11:00am

You Can Explore These Remote Astronomical Observatories on Street View

By nature, astronomical observatories have to be remote—far away from humans and cities and light pollution. That makes these extraordinary facilities difficult to visit, unless you've got Google Street View. Three of Chile's most remote observatories are now open to the digital tourist, and we've found you some of… » 6/10/14 5:40pm 6/10/14 5:40pm

Scientists: 100 million worlds may have complex alien life in our galaxy

A group of international astronomers and astrobiologists have published new research that assesses the possibility of complex life on other worlds. Their calculation in the Milky Way alone is staggering: 100 million worlds in our home galaxy may harbor complex alien life. One. Hundred. Million. » 6/09/14 2:34am 6/09/14 2:34am

Tonight's Meteor Shower Will Be Like Watching the Jump to Light Speed

Already being hyped as one of the best of 2014—with some calling it a once-in-a-lifetime experience—the Camelopardalids meteor shower, which starts tonight, will also be unlike many meteor showers you might have seen: Instead of lights streaming across the sky diagonally, the meteors will be radiating out from a very… » 5/23/14 4:40pm 5/23/14 4:40pm

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

The Lick Observatory's Newest Telescope Is an Exoplanet Hunting Robot

Exoplanets—planets orbiting stars that aren't our Sun—seem to be popping out of the cosmic woodwork now that we know where and how to look for them. The Kepler mission alone has discovered 961 of them, and it's only looking at a tiny sliver of distant space. Just think of how many we'll find when the new James Lick… » 3/28/14 5:40pm 3/28/14 5:40pm

Astronomers Discover First Direct Proof of the Big Bang Expansion

Somebody's going to win a Nobel Prize. At least that's what the physics community is saying after the announcement on Monday that a Harvard team has found the first direct evidence of cosmic inflation right after the Big Bang. It's more proof that the Big Bang really was the beginning of it all. » 3/17/14 12:20pm 3/17/14 12:20pm

22 Amazing Observatories Where Our Radio Eyes Watch the Universe

Humans can only see visible light—the portion of the electromagnetic spectrum that is visible to the human eye. That's why so hard to study celestial objects hidden behind cosmic dust. But radio astronomy reveals those parts of the Universe that can't be seen in visible light—and the secrets of dust-shrouded galaxies… » 2/25/14 9:00am 2/25/14 9:00am

The Worst Blunders People Make in Inventing Fictional Alien Worlds

We love stories that take us to alien planets and let us explore whole new environments. But not every alien planet is totally realistic, especially given how much we've learned about exoplanets lately. So we asked six experts to tell us the biggest mistakes they see in fictional habitable worlds — and here's what… » 2/20/14 5:40pm 2/20/14 5:40pm
