How a planet comes together has implications for whether it captures and retains the volatile elements, including nitrogen, carbon and water, that eventually give rise to life, according to scientists ...

Most of the carbon and nitrogen in our bodies probably came from a planet the size of Mars crashing into Earth 4.4 billion years ago, scientists say. Researchers have long thought that these elements, ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...

Around 3.5 billion years ago, life began to sprout on a fairly quiet, desolate planet we call Earth. Tracing the origins of life, and how molecules combined to create microbial life, is perhaps the ...

One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research programme. This will involve studying in the laboratory ...

Before the planets in our solar system formed or the Sun turned on and started shining, two other stars had to die. Their deaths and later collision would seed the area where our area with many of the ...

Even if early Earth had water and oxygen, the planet would still have needed another ingredient for life to flourish: heavy metals. Our cellphones, Earth’s core and even human metabolism would ...
