Telescopes dot the cloudless top of the dry volcano Mauna Kea in Hawaii, Earth’s tallest mountain from its underwater base to its peak. Its night skies, free of artificial light, are a resource disappearing across the planet in the face of light pollution.
Sometimes, the best telescopes on Earth need a little help making their observations more meaningful. NASA announced yesterday that it had decided to fund the Imaging X-ray Polarimetry Explorer (IXPE, pronounced ix-pee) mission, a polarized X-ray telescope, to help the bigger telescopes explore some of space’s…
Good ol’ ‘Murica may be ahead of China in development, GDP, and political clout, but China just finished building the world’s largest radio telescope and is now better-equipped at searching for aliens.
Prehistoric humans may have observed the sky via primitive lens-less “telescopes,” according to a team of British astronomers who have studied the long passageways of ancient megalithic tombs. The details were presented today by Kieran Simcox, a student at Nottingham Trent University, at a meeting of the Royal…
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.
The U.S. Department of Energy has green-lit the construction of a 3.2-gigapixel digital camera for the Large Synoptic Survey Telescope (LSST). Once complete, the instrument will be used by astronomers to study everything from the Big Bang to the motions of nearby asteroids.
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.
Remember the wonderful Galileoscopes that were developed in 2009 for the International Year of Astronomy? This high-quality, low-cost telescope kit is back for the 2015 International Year of Light (IYL), and new inventory is now available for delivery worldwide. Plus, thanks to generous donations to support science…
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.
The world's most famous astrophysicist now has a vastly improved view of the cosmos. He was recently visited by employees of Celestron, who installed an 11-inch telescope in his home. Hawking has quickly taken to the telescope and he's already posted some incredible images.
Normally, images as detailed as this infrared shot of Jupiter can only be captured by space-based telescopes or planetary probes. But this picture, taken with a special camera on the Subaru Telescope, was captured from our planet's surface.
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.
