Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable... more

Fractured rocks of impact craters have been suggested to host deep microbial communities on Earth, and potentially other terrestrial planets, yet direct evidence remains elusive. In a new study published... more

Earth-like planets may be common in the universe, a new study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not unique. more

Oxygen fugacity is a measure of rock oxidation that influences planetary structure and evolution. Most rocky bodies in the Solar System formed at oxygen... more

Mars may seem to be an alien world, but many of its features look eerily familiar—such as this ancient, dried-up river system that stretches out for nearly 700 kilometres across the surface, making it one of... more

How do you start a fusion reaction, the process that lights the sun and stars, on Earth? Like lighting a match to start a fire, you... more

The European Southern Observatory (ESO) has released an incredibly beautiful image of an Oort cloud comet called C/2016... more

A hot, molten Earth would be around 5% larger than its solid counterpart. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar System and the understanding of Earth itself. more

Life imitated art Tuesday when "The Big Bang Theory"—the popular U.S. television show, not the scientific explanation for how the universe began—made its way into the annals of... more

This year's Nobel Prize for Physics honoured Michel Mayor and Didier Queloz, Swiss astronomers who proved the existence of a planet orbiting a star far beyond the Earth's solar system. more

Limits to growth lie at the heart of how all living things function. The diversity of life is staggering. From microscopic algae to elephants, life has devised countless ways to thrive in... more

From microscopic algae to elephants, life has devised countless ways to thrive in every environment on the planet. But while biologists have tended to focus on the many varied forms that species... more

At a recent event in Boca Chica, Texas, SpaceX CEO Elon Musk confirms that, to his knowledge, we haven't yet discovered aliens. more

A new study of the Ovda Fluctus lava flow on Venus indicates that it is made of basaltic lava. This discovery weakens... more

A Mediterranean wide study has found that 71% of sampled recreational boats hosted alien marine species. Over half carried an alien species... more

I've said many times in the past that the Earth is the best planet in the universe. No matter where we go, we'll never find a... more

In order to explore the moon or Mars, astronauts need smart habitats that will support life and remain operational when they are vacant. To advance the design of autonomous systems for space habitats, NASA... more

This is the first study in the Mediterranean to combine boat and marina sampling data with crew surveys to better understand the... more

Venus, our solar system's broiling, radiation-bombarded, sulfuric-acid-raining, toxic hellscape of a planet, may once have been quite nice, actually. more

Washington State University scientists have developed a way to triple the shelf life of ready-to-eat macaroni and cheese, a development that could have benefits for everything from space travel to military use. more
