Search for Life

The skepticism and debate around the question of "are we alone in the universe" makes the field of astrobiology more cautious

A walk in the desert and a curious discovery could have revealed that the secrets of alien life grow in the harshest conditions on Earth in the form of lichen.

The skepticism continues over recent claims of possible hints of alien life on exoplanet K2-18b.

There are creatures here on Earth that may give us clues about how to communicate with extraterrestrial intelligence — dolphins, which are famously social and smart.

Scientists have discovered 26 previously unknown bacterial species in the clean rooms that were used to prep NASA's Phoenix Mars lander for its 2007 launch.

A unique type of bacteria appears to have social groups — left alone, they'd die.

An independent analysis of recent data from K2-18b casts doubt on claims of detecting alien life on the distant exoplanet.

As scientists, we must not forget our collective direction: the pursuit of truths and our responsibility to share these truths — and only these truths — with humanity.

Last week, scientists announced they found the "strongest evidence yet" of alien life beyond our solar system. However, the scientific community remains skeptical.
