NASA has not found any credible evidence of extraterrestrial life but is exploring the solar system and beyond to help us answer if we are alone in the universe.

Usually, the search for extraterrestrial intelligence has focused on signals within our galaxy. This new approach goes further, looking at distant galaxies.

A team of international scientists has announced the discovery of Gliese 12 b, a temperate, Earth-sized exoplanet just 40 light-years away—a relatively neighborly 378 trillion kilometers from our planet.

Scientists have been forced to reconsider many previously held notions about planet formation and evolution and what conditions are necessary for life.

The study combines data across multiple fields of study and discusses how information on the complicated history of life on our planet from a single field cannot be viewed in isolation.

A NASA experiment suggests that if signatures of life in the form of organic molecules could survive just under the surface ice despite the harsh radiation on these worlds.

A team of astronomers has identified a temperate exoplanet as a promising super-Earth ice or water world.

A new study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.

NASA-supported researchers have created a simulation to better understand how objects in our solar system’s main asteroid belt were formed.

An early analysis of the Bennu sample, published June 26 in Meteoritics & Planetary Science, demonstrates that excitement about the sample was warranted.
