River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface.

Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.

Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth.

The nearest stellar system consists of the stars Proxima, alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets are likely to be significantly influenced by the orbital evolution of the system.

M-dwarfs or red dwarfs are small (0.5-0.1 solar-mass) and cool ( ~3,000 kelvin) stars and are abundant in the universe.

The scientific interest in directly image and identifying Earth-like planets within the Habitable Zone (HZ) around nearby stars is driving the design of specialized direct imaging mission such as ACESAT, EXO-C, EXO-S and AFTA-C.

We report on a search for engineered signals from a sample of 692 nearby stars using the Robert C. Byrd Green Bank Telescope (GBT), undertaken as part of the Breakthrough Listen Initiative search for extraterrestrial intelligence.

Is Proxima c hiding in this graph?

A new study led by ANU has found that animals and plants may live in warm caves under Antarctica's glaciers.

The Rosetta space probe discovered a large amount of organic material in the nucleus of comet "Chury."

For decades, as astronomers have imagined advanced extraterrestrial civilizations, they categorized such worlds by the amount of energy their inhabitants might conceivably be able to harness and use.

A new X-ray study has revealed that stars like the Sun and their less massive cousins calm down surprisingly quickly after a turbulent youth.

The nearby exoplanet Proxima Centauri b will be a prime future target for characterization, despite questions about its retention of water.

Over the last decade, Aperture Arrays (AA) have successfully replaced parabolic dishes as the technology of choice at low radio frequencies - good examples are the MWA, LWA and LOFAR.

We present a three-species multi-fluid MHD model (H+, H2O+ and e−), endowed with the requisite atmospheric chemistry, that is capable of accurately quantifying the magnitude of water ion losses from exoplanets.

he discovery of boron on Mars gives scientists more clues about whether life could have ever existed on the planet, according to a paper published today in the journal Geophysical Research Letters.

The primordial soup that sloshed around billions of years ago, and eventually led to first life on our planet, might have been teeming with primal precursors of proteins.
