V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

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 ...

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

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. It’s an unprecedented ...

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the ...

How can timing influence planetary formation and evolution? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers investigated the ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy – and why the life and death of nearby stars are an important piece of the puzzle. In a paper ...

This video explores how scientists determine the ages of planets and which worlds formed first, based on planetary formation, geology, and evidence from space missions.

Of the more than 6,000 known exoplanets in the Milky Way, so-called Sub-Neptunes are the most common. They are smaller than Neptune and more massive than Earth and believed to have rocky interiors ...

Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and ...
