There could be up to 10 billion warm and cozy Earth-like planets in our home galaxy, new research reveals
Thanks to the Kepler telescope, scientists have enough data to estimate how many sun-like stars have Earth-like planets that could hold liquid water.
Astronomers have discovered a potentially habitable world just 31 light-years away, thanks to NASA’s planet-hunting telescope
TESS, a space telescope searching for alien worlds, helped astronomers discover a potentially watery new planet. It's one of the nearest known worlds.
NASA’s newest planet-hunting telescope just discovered a ‘super-Earth’ and 2 ‘sub-Neptunes’ less than 75 light-years awa...
TESS, the space telescope searching for alien worlds, has discovered three nearby exoplanets that could offer clues about how planets form.
An incredible new animation shows where, when, and how astronomers found 4,000 planets beyond our solar system
Since 1992, astronomers have discovered thousands of new worlds in deep space, and some may be habitable. A new YouTube video celebrates that feat.
The speed of light is torturously slow, and these 3 simple animations by a scientist at NASA prove it
A scientist at NASA animated how long it takes light to travel around Earth, to the moon, and to Mars. The movies show just how slow light can be.
Scientists have discovered a new planet twice the size of Earth, and it could have liquid water on its surface
Scientists have discovered a new planet that's 226 light-years away. It is roughly twice the size of Earth, which is rare for an exoplanet.
Astronomers found a ‘cold super-Earth’ less than 6 light-years away — and it may be the first rocky planet we’ll photograph be...
Astronomers think they've found a "cold super-Earth." It might be the first exoplanet they photograph with a coming generation of powerful telescopes.
The Kepler space telescope was launched in 2009 and has stared down more than 500,000 stars. But NASA says Kepler has run out of fuel.
A $1 billion telescope that will take pictures 10 times sharper than Hubble’s is now officially under construction
The Giant Magellan Telescope is finally under construction at the Las Campanas Observatory in Chile. The telescope is on track to be the world's largest and most powerful when it takes it first images of space. Data collected by GMT could help astronomers "sniff" alien atmospheres.
NASA’s biggest-ever hunt for alien planets is finally underway — and the agency expects to discover ‘strange, fantastic worlds’...
TESS, the Transiting Exoplanet Survey Satellite, is a space telescope designed to discover small, rocky, Earth-like exoplanets in nearby solar systems. NASA launched the observatory on April 18, but it took months for it to reach an orbit near the moon and begin scanning the skies.
