Mars may now be considered a barren, icy desert but did Earth's nearest neighbour once harbour life?
Both Earth and Mars currently have oxidising atmospheres, which is why iron-rich materials in daily life develop rust (a common name for iron oxide) during the oxidation reaction of iron and oxygen. The Earth has had an oxidising ...
Early planetary migration in the solar system has been long established, and there are myriad theories that have been put forward to explain where the planets were coming from. Theories such as the Grand Tack Hypothesis an ...
The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous ...
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the ...
Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.
A new study suggests that tiny, mineral grains—squeezed and mixed over millions of years—set in motion the chain of events that plunge massive tectonic plates deep into the Earth's interior.
Global leaders will try to reignite international environmental diplomacy on Monday, with a biodiversity summit that launches a critical year for efforts to stem the devastating effects of global warming and species loss.
