The space agency is promoting some of the 1,000 planets discovered by the Kepler Mission in the style of vintage travel posters.
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.
The Sphere instrument on the VLT in Chile peers with all its might into the blackness around a binary star system and returns a surprise for astronomers.
You might not have realized that sprites are real, but this new photo taken at the Paranal Observatory in Chile proves otherwise -- sort of.
It might be only eight minutes long, but a new European Space Agency video takes you all the way from the moon's "cataclysm" to its future.
Haven't been finding enough alien life lately? Maybe Harvard can help with a new course that combines astronomy and biology to examine how we look for life on other planets.
In 2014, humanity tagged a comet and became better acquainted with Mars and our place in the universe. Take a tour through the year in space.
