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

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 ...

Why is it so rare to find exoplanets orbiting two stars, also called circumbinary planets (CBPs)? This is what a recent study published in The Astrophysica | Space ...

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

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

Previous Spitzer studies have indicated the formation of complex molecules in the Helix Nebula.

Jupiter is the largest planet in our Solar System and the fifth planet from the Sun. It is a massive gas giant made mostly of hydrogen and helium, the same elements that form stars.

New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing link in planet formation.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

NASA's Juno spacecraft has provided the most accurate measurements of Jupiter's size and shape, revealing it is slightly smaller than previously thought. This research enhances understanding of the ...

A Sun-type star situated nearly 3,000 light-years from Earth has provided astronomers with a unique opportunity to observe an unusual after-effect of a planetary system’s evolution. When this star, ...
