NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars. “MAVEN has been

These prominent trenches were formed by faults that pulled the planet’s surface apart less than 10 million years ago. The images were taken by ESA’s Mars Express on 27 January, and capture part of the Cerberus Fossae system in the Elysium Planitia region near the

Scientists from The Australian National University (ANU) and overseas have discovered molecules of fat in an ancient fossil to reveal the earliest confirmed animal in the geological record that lived on Earth 558 million years ago. The strange creature called Dickinsonia, which grew up to

Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers at NYU Abu Dhabi that challenges current science on how stars rotate. Until now, little was known about the precise rotational patterns of

Astrobiology, the study of the origin, evolution and future of life on Earth and beyond, is a multidisciplinary field that has expanded rapidly over the last two decades. Now, a consortium of organisations has announced plans to establish a European Astrobiology Institute (EAI) to coordinate

The discovery of a microorganism that gives a candy-pink lagoon in central Spain its startling colour is providing new evidence for how life could survive on a high-salt diet on Mars or Europa. The Laguna de Peña Hueca, part of the Lake Tirez system in

Two of the closest galaxies to the Milky Way—the Large and Small Magellanic Clouds—may have had a third companion, astronomers believe.

An unusual infrared light emission from a nearby neutron star detected by NASA’s Hubble Space Telescope could indicate new features never before seen.

Astronauts on a mission to Mars would be exposed to at least 60% of the total radiation dose limit recommended for their career during the journey itself to and from the Red Planet, according to new data.

The line that separates stars from brown dwarfs may soon be clearer thanks to new work led by Carnegie’s Serge Dieterich.
