Webb exposes complex atmosphere of starless super-Jupiter

An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric ...

Mission concept proposes sampling Enceladus's subsurface ocean

How can we explore Saturn's moon, Enceladus, to include its surface and subsurface ocean, with the goal of potentially discovering life as we know it? This is what a recent study presented at the American Geophysical Union ...

Ancient beaches testify to long-ago ocean on Mars

A Chinese rover that landed on Mars in 2021 detected evidence of underground beach deposits in an area thought to have once been the site of an ancient sea, providing further evidence that the planet long ago had a large ...

If you're going to call aliens, use this number

Let's dive into one of those cosmic curiosities that's bound to blow your mind: how we might chat with aliens. And no, I'm not talking about elaborate coded messages or flashy signals. We're talking about something incredibly ...

Sulfur may be a new tool for finding alien life

Astronomers have identified sulfur as a potentially crucial indicator in narrowing the search for life on other planets. While sulfur itself is not necessarily an indication of habitability, significant concentrations of ...

Jupiter's moon Callisto is very likely an ocean world

More pocked with craters than any other object in our solar system, Jupiter's outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA's Galileo spacecraft captured ...

A new theory explains how water first arrived on Earth

When Earth first formed, it was too hot to retain ice. This means all the water on our planet must have originated from extraterrestrial sources. Studies of ancient terrestrial rocks suggest liquid water existed on Earth ...

Exploring extremes in the search for life on Mars

People might assume the search for life on Mars ended when NASA's first rovers sent back images of the planet's barren, inhospitable surface. However, as scientists broaden their understanding of the extreme conditions in ...

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 ...
