For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

Theories around the formation of Earth have just been challenged by researchers from ETH Zurich. For a long time, the general idea saw our planet forming from a mixture of local planetesimals – the ...

Add Yahoo as a preferred source to see more of our stories on Google. A view of HOPS-315, a baby star some 1,400 light-years from Earth where astronomers have observed evidence for the earliest stages ...

Next summer, Balmer will continue these inquiries as they and their Northwestern host, Assistant Professor Jason Wang, plan ...

The universe is at it again; scientists have been baffled by a discovery that turns all the knowledge they have on planetary ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have ...

The Artemis II mission, which took four US astronauts around the Moon and to a record-breaking distance from Earth, was a ...

CAPE CANAVERAL, Fla. — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

Discover how a rare "kiss and capture" impact gave rise to the Pluto-Charon binary system, shedding new light on the evolution and motion of icy worlds in the outer solar system. (CREDIT: NASA) ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.
