The Earth formed much faster than previously thought

The precursor of our planet, the proto-Earth, formed within a time span of approximately five million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University ...

Image: Hera logo aboard ISS

The logo for Hera, ESA's proposed asteroid mission for planetary defense, has already reached space, thanks to ESA astronaut Luca Parmitano, who snapped this photo from the cupola of the International Space Station. The Hera ...

ALMA observes the formation sites of solar-system-like planets

Researchers have spotted the formation sites of planets around a young star resembling the sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in the solar system, ...

How comets are born

Detailed analysis of data collected by Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies.

Largest rocky world found

We thought we understood how big rocky planets can get. But most of our understanding of planetary formation and solar system development has come from direct observation of our own solar system. We simply couldn't see any ...

Scientists predict that rocky planets formed from 'pebbles'

Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also ...

Solar System formation don't mean a thing without that spin

New work from Carnegie's Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is published by The Astrophysical ...
