A device known as "Sphere," attached to the Very Large Telescope in Chile, has achieved first light using three novel methods to peek into the brightness.
Humanity's most advanced telescopes have begun to confirm distant planets circling their stars within the habitable zone. Use a conservative definition of what makes a potentially habitable planet, and these 7 exoplanets still make the grade.
For centuries, distant planets were the stuff of sci-fi, but in recent years, science has begun to confirm their existence. Take a quick tour of the more than 1,700 (so far) known exoplanets in the visible universe.
NASA's Chandra X-ray Observatory captures the first-ever X-ray of an exoplanet passing in front of its parent star in a system that is 63 light-years from Earth.
Researchers believe they've found the first rocky, Earth-like exoplanet to orbit a distant binary star system. That's good news for the search for habitable worlds, not to mention real-life analogs to the "Star Wars" universe.
NASA scientists and top space experts outline plans to advance the search for life on other worlds.
Seven of a multitude of exoplanets whose existence have been confirmed in recent years stand out as the most likely to host liquid water and, perhaps, life. Take an intergalactic tour in search of E.T. with Crave's Eric Mack.
Identifying distant planets that might be able to support life turns out not to be as straightforward as we might think, new research finds.
NASA confirms the discovery of an Earth-sized planet that may have potential for life, but its sun is dimmer than ours. Here's what an evening stroll on a beach on Kepler-186f might be like.
Kepler-186f orbits an M dwarf star in the constellation Cygnus. More importantly, it's the first confirmed Earth-size, potentially habitable planet elsewhere in the universe.
