Proteins before planets: How space ice may have created the 1st building blocks of life

“We used to think that only very simple molecules could be created in these clouds. But we have shown that this is clearly not the case.”

Astronomers searching for alien life are sharpening our cosmic clocks. Here’s why

Tiny delays in pulsar signals measured by SETI scientists could aid the search for gravitational waves and extraterrestrial life.

This SETI program is chasing down its final 100 signals. Could one of them be from aliens?

SETI@home has been one of the largest citizen science projects ever, with millions of users around the world.

Jupiter ocean moon Europa likely lacks tectonic activity, reducing its chances for life

New models suggest that Europa has very little tectonic activity at its seafloor, which is potentially catastrophic news for the hopes of finding alien life within its ocean.

How did life begin on Earth? New experiments support ‘RNA world’ hypothesis

The new findings strengthen the “RNA world” hypothesis that describes how the first life on Earth could have used RNA instead of DNA.

Can scientists detect life without knowing what it looks like? Research using machine learning offers a new way

If nonliving materials can produce rich, organized mixtures of organic molecules, then the traditional signs we use to recognize biology may no longer be enough.
