Neil deGrasse Tyson’s tweets make us laugh and make us cry … from laughter.

If there are aliens or fossils of previous extraterrestrials on Mars, scientists are going to have to know where to look. That’s where this Earth desert and its bacteria tenants come in.

We may soon know for sure whether extraterrestrial life ever existed in other places within our solar system, but don’t expect to shake hands with an alien any time soon.

A fleet of robots that could one day travel to other planets and moons looking for aliens are packed with tools like buzzsaws and catapults.

Scientists think they’ve figured out exactly how much air the Sun has sucked off of Mars, turning it from a warm and wet planet into a red wasteland.

Tom DeLonge, who used to sing and play guitar for the pop-punk band, spoke to Hillary Clinton aide John Podesta about UFOs.

In order to explain the origin of these mysterious bursts of radio emissions, two researchers from the Harvard-Smithsonian Center for Astrophysics have put forward a controversial idea — aliens are causing them.

Scientists are learning more about how the dwarf planet Ceres formed, with an eye on whether there could be extraterrestrial life there.

A new study based on climate models of hypothetical exoplanets has shown that the presence of hydrogen-spewing volcanoes could expand a star's habitable zone.

We have all been faced with the exasperating situation when our electronic devices start to act up for no perceptible reason.

Churchill wrote the essay on the eve of World War II.

"Any civilization detecting our presence is likely to be technologically very advanced, and may not be disposed to treat us nicely."

Math is the universal language no matter the culture, and scientist believe the same can be said for aliens.

Two astronomers think the signals coming from more than 200 planets could be messages from aliens.

Project Blue plans to launch its lightweight telescope into space by the end of the decade to take the first picture of an Earth-like planet.

A team of researchers has released a catalogue 216 planets discovered by NASA's Kepler telescope, including 20 that are most likely to resemble Earth.

According to a new study, odds are that we — Earthlings — popped into existence a tad bit early. Life elsewhere, it suggests, may be yet to emerge.

The world’s six richest countries account for at least 60 percent of the global economy but host less than 9 percent of refugees, an Oxfam report said Monday.
