These snake-shaped robots, called EELS, could one day explore the subsurface ocean of Saturn's moon Enceladus in search of life.

"I believe that there's every chance advanced civilizations are out there," said researcher Nalini Heeralall-Issur.

Stars containing higher levels of heavier elements may have orbiting planets that are less hospitable to life, researchers have found.

While the videos show strange objects spotted flying through the sky, there is still no concrete evidence of aliens.

"If there are signs of life in dust grains, not only could we be certain, but we could also find out soon," Japanese astronomer Tomonori Totani said.

Journalist Payne Lindsey talks to Newsweek about the unexpectedly perfect timing of his upcoming UFO podcast 'High Strange.'

Professor John Zarnecki told Newsweek that it seems unlikely an advanced civilization would travel vast distances only to deploy balloons over Earth.

The barren landscape of Antarctica is concealing hidden ecosystems, which might give us clues about life on other planets.

At 40 light years away from Earth, TRAPPIST-1's four Goldilocks zone planets are one of the prime candidates for finding extra-terrestrial life.

Researchers looked at the possibility of one nation monopolizing any alien interaction, and the likelihood of international conflict.

The rocky worlds have the potential to harbor liquid water, but until now scientists have been unable to tell if they have atmospheres.

By studying light from distant worlds, Webb will play a key part in the ongoing search for life on other worlds.

America's "space agency" picking up the UFO ball was bound to raise eyebrows and concerns for NASA's reputation. But if it's handled well, the commission could do more than shed much-needed light on UAPs. It could also give Americans a masterclass in the most basic, most important, and unfortunately, most boring topic in science: Standards of Evidence. They are the key to knowing if we are alone in the Universe or not.

A study of 2,000 adults found 37 percent believe they've witnessed something "out of the ordinary," although 35 percent put it down to an optical illusion.

From fast radio bursts to pulsars and other strange signals, the alien-hunting FAST telescope has made a number of discoveries in its short life.

During a congressional hearing on UFOs, the Defense Department's under secretary for intelligence said transparency was the objective.

The hearing "will give the American people an opportunity to learn what there is to know about these incidents," said Rep. André Carson.

The panel chair for the upcoming hearing, Representative André Carson, said the issue of unidentified aerial phenomena was a "national security threat."

Stephen Hawking, one of the greatest physicists ever, once warned that aliens "may not see us as any more valuable than we see bacteria."

Relatively recent ice volcano activity on Pluto raises the possibility of liquid water beneath the freezing planet's surface.

Astronomers spotted the large organic molecule in a cashew-shaped "dust trap" around the young star IRS 48 located 444 light-years from Earth.

Avi Loeb, head of the Galileo Project investigating UFOs at Harvard, told Newsweek he doubted the government would release videos, and said a better approach is getting new data.

The mysterious space rock was noticed speeding through our solar system in 2017, and some have suggested it may have come from an intelligent civilization.

The past 12 months have been a bumper period for missions like NASA's Perseverance Rover, with evidence of water discovered beneath the Martian surface.

Scientists want to know if life exists in what are known as the Goldilocks zones around the sun's stellar neighbors. How long would getting there take?

The discovery of water vapor trailing the Jovian moon sets the scene for future missions that will determine if Europa could harbor life.

The "very strange" signal came from near the galactic center, and no current hypotheses can explain what caused it.

Red dwarfs often shoot out dangerous flares, but scientists have discovered their planets may be lucky enough to avoid them.

The U.S. government is expected to release a highly anticipated report on UFOs this week, sparking much interest in the possibility of alien life.

The former NBA star said he had been on a double date in 1997 when he witnessed something really strange.
