Search for Life

The U.S. Navy admitted that it has unreleased videos of UFO encounters but refused to share them due to 'national security concerns.'

Dozens of 'phantom' and 'cosmic' UFOs have been detected in the skies over Ukraine, a new government report claims.

NASA's Perseverance Mars rover has collected four samples from an ancient Red Planet river delta in the past few months, and all point toward a formerly habitable environment.

The search for signs of life, past or present, on Mars may have hit a stumbling blocks as new results show how the rovers will be unable to detect biomarkers on the surface.

The find could boost the search for alien life.

Astronomers have discovered two super-Earths orbiting an ultracool dwarf star 100 light-years away, and one of the planets could support the existence of liquid water, a vital ingredient of life.

Astronomer Frank Drake, who pioneered the modern search for intelligent life in the universe, passed away Friday (Sept. 2)at the age of 92.

Cosmic impacts can make planets and moons more porous than previously thought, potentially boosting their ability to host life, a new study finds.

A potentially habitable water-rich world just 100 light-years away from Earth could be one of the best places to search for life.

Rocket Lab aims to send a probe to Venus soon, and a new paper lays out the details of the ambitious mission.

Exoplanet images might be contaminated by the light from their neighbors, a new study suggests, but scientists are learning how to remove the effects of these photobombers.

Perseverance Mars rover is gathering up samples of Martian rock and soil that could help tease out an answer concerning past life on Mars.

Curiosity landed on Mars on Aug. 5, 2012, with one main goal: to determine whether the planet was once habitable. In 10 years, it has answered that question and many others.

NASA's car-sized Perseverance Mars rover drilled out and sealed up its 12th rock sample on Wednesday (Aug. 3), its fourth such operation in less than a month.

But could these giant, rocky planets actually sustain the conditions for life? Or is life limited to smaller planets like our own?

Low mass and dim red dwarf stars account for 75% of stars in the Milky Way and astronomers are attempting to discover planets that orbit them.

The genetic tree of life suggests that the first life on Earth may have lived underwater, shielded from harmful ultraviolet light from the sun.

The redesigned NASA-European campaign will task the Perseverance rover with delivering Red Planet samples to a rocket, with the drones as backup retrieval options.
