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.

The ocean on Saturn’s moon Enceladus contains the building blocks of life, NASA data reveals

NASA data revealed the most basic ingredients of life in bursts from an ocean on Saturn's moon Enceladus.

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.
This artist's concept depicts astronauts and human habitats on Mars.

NASA’s future missions will explore an icy moon of Jupiter, collect samples on Mars, and more. Here’s what’s coming in the next 10 y...

NASA intends to return to the moon, continue on to Mars, and look for life near Saturn and Jupiter within 10 years. Its other plans go even further.
An apparently unidentified object detected on a Navy plane’s infrared camera.

No, the UFOs or ‘unidentified aerial phenomena’ in those grainy Navy videos probably aren’t aliens

In 2017, The New York Times published Navy plane footage showing a mysterious flying object. Today, the Navy confirmed this object was "unidentified."
This artist’s impression shows the planet K2-18b, its host star, and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life.

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.
An artist's concept of a lake at the north pole of Saturn's moon Titan. The raised rims and rampart-like features reflect the observations made by NASA's Cassini spacecraft.

Lakes of methane on Saturn’s moon Titan may be the craters of giant explosions, a new study shows

NASA's Cassini probe at Saturn revealed lakes with steep rims on Titan. They could be craters created by exploding nitrogen.
The Milky Way's spiral centers around a supermassive black hole. Scientists think that every galaxy has one at its center.

Alien civilizations may have explored the galaxy and visited Earth already, new study says. We just haven’t seen them recently.

The answer to the Fermi Paradox could be that aliens have already visited Earth, a study says. But it might have been more than 10 million years ago.
In the 1979 movie "Alien," the xenomorph tries to attack Sigourney Weaver's character.

The iconic film ‘Alien’ came out 40 years ago. A scientist explains why Hollywood depictions of extraterrestrials have changed since then....

It's been 40 years since "Alien" came out. The aliens now depicted in Hollywood blockbusters are less humanoid and more scientifically plausible.
An artist's concept of the planet Kepler-452b (right), the first near-Earth-size world to be found in the habitable zone of a star that is similar to our sun. The planet is 60% larger than Earth (shown left for comparison).

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.
