Six Busy Days (and Nights) With Some of the World's Largest Telescopes 

Night falls in the Atacama Desert, but the day is far from over. In this wonderful little timelapse, sent along to us by the photographer Enrico Sacchetti, we get a sense for the constant work being done at the European Southern Observatory. » 2/02/15 8:00pm 2/02/15 8:00pm

The World's Biggest Telescope Is Finally (Really) Complete

Though the massive 66-antenna ALMA array in Chile's Atacama desert has been online since last October when the last of its 54, 12-meter radios was installed, the system has only been operating at a fraction of its potential resolution. But with the delicate delivery of 12 additional 7-meter radio dishes—the last of… » 6/16/14 2:20pm 6/16/14 2:20pm

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

Supermassive Black Hole 'Indigestion' Is Super Gorgeous

On the other side of the universe, a supermassive black hole is devouring enormous quantities of matter and spewing material in a jet that's 150 light years long. One scientist identifies the situation as "black hole indigestion," and boy, is it pretty. » 10/17/13 12:41pm 10/17/13 12:41pm

The World's Biggest Telescope Is Finally Online

With the arrival of the 54th—and final—12-meter wide radio telescope, the single largest astronomical project humanity has ever under taken can finally begin peering into the heavens at full strength. » 10/01/13 2:20pm 10/01/13 2:20pm

Zoom in on the Birth of a Star from Thousands of Light Years Away

About 1,400 light years from Earth in the constellation of Vela, a new star is being born in a burst of violent glory. Streams of carbon monoxide molecules are spewing from the star's poles, as dust swirls around the entire event. Thank God somebody got the whole event on camera. » 8/20/13 6:20pm 8/20/13 6:20pm

A Gaseous Umbilical Cord Ties Mother Stars to Baby Planets

Something never quite added up in the conventional model of solar system formation. It dictates that planets are formed from the accretion disc around a young star, but it also dictates that a star continues to feed off the same material as it grows and matures. So how to both bodies grow using a limited supply of… » 1/03/13 8:20pm 1/03/13 8:20pm

This Galactic Timelapse Just Needs Some Alien Fighters

José Francisco Salgado is an astronomer at the ALMA observatory in the Atacama desert, Chile. He's also a great photographer who creates these awesome timelapses. It just needs some alien spaceships attacking Earth. Or maybe just some Nazi UFOs. [Thanks Karl!] » 2/07/11 9:00am 2/07/11 9:00am

What Is This?

My guess: An alien beacon recently discovered at Llano Chajnantor, 16,450-feet high in the Chilean Atacama desert, 50 kilometers to the east of San Pedro de Atacama. In reality, its name is APEX, and it's a galactic vacuum cleaner. » 12/30/10 9:20pm 12/30/10 9:20pm
