One of the most incredible things about black holes is how much bigger they are than almost anything else out there. Now, a new image taken at the Atacama Large Millimeter/submillimeter Array (ALMA) Observatory shows that we’ve been totally wrong about how they manage to grow so large.
Astronomers have captured an image of a dense clump of dust orbiting around a young star—and they’re saying it could be our first glimpse of a planet in the very earliest stages of formation.
I have only one piece of advice: Watch out for the spikes before sitting down when you are about to inspect radio telescope antenna.
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.
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…
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…
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.
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.
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.
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…
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.
