Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

Astronomers have detected a relatively close exoplanet orbiting in the habitable zone of its star, where temperatures are ...

New research suggests Earth was once a purple planet. Early microbes used retinal, not chlorophyll, for photosynthesis.

The exoplanet, discovered in 2009, remained elusive due to dense clouds. Now, scientists have peered through with the James ...

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how ...

An international team of scientists has confirmed the discovery of a super-Earth—a planet larger than Earth but smaller than ...

While our solar system is a fascinating place on its own, exoplanets are even more of a mystery. And one exoplanet in particular is something quite new.

NASA said the system is thought to be moving at least 1.2 million miler per hour, nearly twice as fast as our solar system.

Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth.

Many scientists have long thought that developing planets should resemble the swirling disk of gas and dust that births them.

Roughly 300,000 years ago, our species first appeared on the African landscape before spreading globally and coming to ...

Is life as rare as we once believed? A new Penn State study suggests that intelligent life is more likely than previously ...
