After Euclid blasts off, it will travel to a spot called Lagrange point 2, about 1.5 million kilometers from Earth, where the telescope will have a clear view of deep space while being able to communicate with astronomers and enjoy…

The NANOGrav team was essentially able to turn the Milky Way into a giant gravitational wave detector by measuring the signals from these pulsars to determine when a wave nudged them. The collision of enormous black holes—or some other…

Throngs of satellites are streaking across the Hubble Space Telescope’s field of view, leaving what look like scratch marks on space photos and hindering scientists’ work. Teeming swarms of these satellites, which reflect sunlight and mimic…

But the word “most” is important. The ACT team’s findings agree with studies of the CMB made with instruments like the European Space Agency’s Planck telescope, which together cover the first 8 billion years of the universe’s life. But…

It's hard to wrap your head around the size of any celestial object, let alone a supermassive black hole, but let's give it a shot. As a starting point, the sun is big enough to hold over a million Earths within its volume…

James Webb led NASA in the 1950s and 60s, during the Cold War–era “Lavender Scare,” when government agencies often enforced policies that discriminated against gay and lesbian federal workers. For that reason, astronomers and others have…

Nov. 4, 2009 — The University of Utah will celebrate the initial observations or “first light” of its new $860,000 research telescope in southwest Utah during a Wednesday, Nov. 11 symposium and reception on…

We live in a time of abundance for the astronomy enthusiast. There are dozens of apps designed to help you navigate the skies and find good viewing locations and weather windows for optimal viewing. On top of all that, optics have never…

The world’s biggest digital camera is finally coming into focus. While a very powerful personal camera might have megapixel resolution, astronomers have constructed a device that will image the distant universe with 3.2 gigapixel…

NASA explained that it aims to prolong Hubble's life. The telescope has been circling 335 miles outside of the planet for over three decades, and its orbit has been "slowly decaying over time." Hubble was conceptually…
