Scientists may have found a planet orbiting two brown dwarfs at a wild 90-degree tilt—something never seen before.

But what is the science behind extraterrestrial life? Is it possible that humans will ever experience "first contact" with an ...

Science, National Security & Innovation' was held on Thursday where scientists had the chance to speak to US Congress members about the evidence for aliens ...

Here are seven exoplanets that are just like Earth, in terms of their size, composition, temperature, and habitability. Kepler-452b is the most Earth-like exoplanet ever found, according to NASA.

The data collected by the Kepler Space Telescope tells us 452b is about 60 per cent bigger than Earth and is in a 385 day orbit around a yellow star some 20 per cent bigger than our own.

It’s a star that’s similar to our own sun, but it’s too faint for us to see from Earth without a telescope. Kepler-452b is sometimes called “Earth’s cousin” or “Earth 2.0”, and ...

A planet one-and-a-half times the size of Earth has emerged as the most likely planet outside our solar system to support alien life. Kepler 452b, which is 1,400 light years away, is in the middle ...

A "super-Earth" 1,400 light years away has emerged as the most likely planet outside our solar system to support alien life. Kepler 452b, discovered in 2015, lies in the middle of a newly ...

At the time, the planet was described as a potentially an ‘older cousin’ or ‘older brother’ to Earth, positioned in the perfect place for life. However, Kepler 452b was confirmed by ...
