A winner of this year’s Nobel prize in physics is convinced we’ll detect alien life in 100 years. Here are 13 reasons why we haven’t...
A Nobel prize-winner thinks we'll detect aliens within 100 years, possibly sooner. Other scientists think we might never make contact.
16 recently discovered exoplanets could offer our best chance of finding alien life outside the solar system
NASA telescopes have found thousands of exoplanets, some of which could host life. Scientists recently detected water vapor on a super-Earth.
Scientists have discovered water vapor on a potentially habitable super-Earth for the first time. That planet is now our best bet for finding alien li...
K2-18b is our "best candidate for habitability," since it's the only known exoplanet with water vapor, an atmosphere, and potential for liquid water.
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.
