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.
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 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.
A helium balloon fitted with six telescopes is currently floating over Antarctica. It's called SPIDER, and it could show what happened during the Big Bang. Scientists will use it to search for patterns of polarization that could have only been made in primordial light in the fractions of seconds after the birth of the…
Look at that. It's like, how much more black could this be? And the answer is none. None more black.
The European Southern Observatory is ready to blast the top of Cerro Armazones to make room for what will be the world's largest optical telescope. The explosion is scheduled for today, June 19th, at 12:30 pm ET. You can watch it live right here at io9.
Using a naturally-existing zoom lens in space, the Hubble telescope has taken the deepest look into a cluster of galaxies ever taken in space to grab these pictures of galaxy cluster Abell 2744.
Today is inauguration day for ALMA, the massive telescopic array that’s still under construction in Chile’s Atacama Desert. But just because it’s not finished doesn’t mean astronomers haven’t been using it. The $1.5 billion telescope has just peered into the deepest realms of the universe, revealing some of the most…
We are about to see what happens when stars come to life. On March 13, the Atacama Large Millimeter/Sub Millimeter Array (ALMA) goes online. It's the most powerful such telescope ever built, and is part of a class of "very large telescopes" that combine the power of several massive antennae to gather information…
The European Southern Observatory has given the initial go-ahead to build the world's largest optical/infrared telescope in the world. Called the European Extremely Large Telescope (E-ELT), the Chilean-based telescope will provide insights into the earliest formation of planetary systems and the potential for life to…
The European Southern Observatory's Very Large Telescope is shooting a freakin big laser into space, to create a virtual star to compensate for the Earth's atmospheric interference.
"Gravitational telescopes" let scientists observe fluctuations in spacetime itself. They are, in a word, crazystupidamazing.
