Scientists help unravel life's cosmic beginnings

Knowledge about the early forms of life in the universe that may have led to the development of life on Earth remains largely unknown. However, a group of scientists at the University of Hawaiʻi at Mānoa are attempting ...

Tracing the origins of organic matter in Martian sediments

Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water once flowed abundantly on its surface. ...

What deadly Venus can tell us about life on other worlds

Even though Venus and Earth are so-called sister planets, they're as different as heaven and hell. Earth is a natural paradise where life has persevered under its azure skies despite multiple mass extinctions. On the other ...

Astronomers are on the hunt for Dyson spheres

There's something poetic about humanity's attempt to detect other civilizations somewhere in the Milky Way's expanse. There's also something futile about it. But we're not going to stop. There's little doubt about that.

Looking for life on Enceladus: What questions should we ask?

Does life exist beyond Earth? One of the most compelling places to consider this possibility is Enceladus, a moon of Saturn with a liquid water ocean encased in a frozen shell. There, plumes of water spray from ice fractures ...

New study delves into ozone's influence on exoplanetary climate

In the quest for life beyond our solar system, a new study delves into the atmospheric dynamics of planet Proxima Centauri b, illuminating ozone's pivotal role in shaping planetary climates. This research signifies a significant ...

What can early Earth teach us about the search for life?

Earth is the only life-supporting planet we know of, so it's tempting to use it as a standard in the search for life elsewhere. But the modern Earth can't serve as a basis for evaluating exoplanets and their potential to ...

Webb telescope probably didn't find life on an exoplanet—yet

Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence ...

New findings point to an Earth-like environment on ancient Mars

A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in ...

Enceladus spills its guts through strike–slip motion

Over the course of its elliptical orbit, the moon Enceladus is squeezed unevenly by Saturn's gravitational pull and deforms from a spherical shape into a football shape and back again. This cyclic stress causes a phenomenon ...

Will we know if TRAPPIST-1e has life?

The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, ...

Did the Galileo mission find life on Earth?

In the fall of 1989, the Galileo spacecraft was launched into space, bound for Jupiter and its family of moons. Given the great distance to the king of planets, Galileo had to take a roundabout tour through the inner solar ...

Mimas' surprise: Tiny moon holds young ocean beneath icy shell

Hidden beneath the heavily cratered surface of Mimas, one of Saturn's smallest moons lies a secret: a global ocean of liquid water. This astonishing discovery, led by Dr. Valéry Lainey of the Observatoire de Paris-PSL and ...

Atmospheres in the TRAPPIST-1 system should be long gone

Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them are potentially habitable. ...

The improbable origins of life on Earth

We do not yet know how, where, or why life first appeared on our planet. Part of the difficulty is that "life" has no strict, universally agreed-upon definition.
