Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth. The model, which ...

How do terrestrial planets like Earth form and evolve to enable life to exist? This is what a recent study published in Nature hopes to address as a pair of scientists from the Southwest Research ...

Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at ...

The black star represents the position of the star. The colored lines are the orbits of two planets. The yellow one is the outer, and it is highly inclined. The inner one is the red one. As time ...

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form. Astronomers like to find such disks because they might be able to catch ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

A new model upends the decades-old “hard steps” theory that intelligent life was an incredibly improbable event and suggests that maybe it wasn't all that hard or improbable. The team of researchers ...
