China is building the biggest radio telescope on Earth. And the country is displacing over 9,000 people to do it.
It’s a clash of gods, science, lava, stars, and the law for the Thirty-Meter Telescope in Hawaii. The would-be new largest telescope on the planet just had its construction permit yanked by the Hawaii Supreme Court.
Astronomers in India have discovered a very unusual galaxy, and it’s dying. By now, in fact, it’s probably already dead.
Construction is well underway on what will become the world’s largest radio telescope. Once complete, the half-kilometer-wide dish will explore the origins of the Universe and scour the skies for signs of extraterrestrial intelligence.
Like new cars, new telescopes come with their own unique smell. Unlike cars, telescopes are delicate enough that this smell can damage the high-precision instruments, killing them with their own outgassing. Here’s how NASA protects fragile space telescopes from themselves.
We are, as Carl Sagan famously said, made of star stuff—and now, your doctor may use a technology designed for studying the stars to examine the inner workings of your eyes. Here’s how it works—and could one day save you from blindness.
Twenty years ago, discovering another Earth sounded like a science fictional dream. But within a generation, astronomers now believe we might do just that.
The Arecibo Observatory in Puerto Rico is one of the most famous telescopes in the world—it’s been in a James Bond film (GoldenEye) as well as Contact. Now that the telescope is aging, though, it’s only looking more dramatic.
One way or another, the Pillars of Creation are toast. Based on new observations at the European Southern Observatory, these awe-inspiring structures have another 3 million years before their ghostly image fizzles away into cosmic nothingness.
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.
Who gave this telescope a light saber? Just kidding: this is, of course, the ESA's Optical Ground Station telescope in Tenerife—in the process of laser tagging the ISS to establish a data connection.
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.
Both terrestrial telescopes and their orbital counterparts have some pretty significant limitations—ground based observatories must deal with the obscuring effects of the Earth's atmosphere and space telescopes are incredibly expensive to launch. But NASA's newest telescope will deliver space-quality observations at a…
About once a century on any given square kilometer of Earth, a cosmic ray hits with mind-boggling intensity. The teeny tiny subatomic particle from space comes careening in with more than 10 million times the energy of particles shot out by the LHC. Where do these ultrahigh energy cosmic rays come from? Astronomers…
Astronomy has come a long way in the 405 years since Galileo's historic first survey of the night sky over Florence in 1609. The next generation of terrestrial telescopes are set to peer deeper into the cosmos and further back in time than ever before. We sat down with Dr. Patrick McCarthy, Director of the Giant…
Last Sunday marked the super-est of super moons we'll have for another 20 years. Luckily, many of you brought your cameras out to immortalize the moment.
Tracking down Earth-like exoplanets with a terrestrial telescope is no easy feat because our planet's atmosphere makes distant solar systems even harder to see. Adaptive optic technology can help make things go a little faster, but it does so at a snail's pace—requiring up to 10 minutes per target. The fully…
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…
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…
