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

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

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.

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

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Add Yahoo as a preferred source to see more of our stories on Google. An illustration showing Planet Nine, a hypothetical, undiscovered planet in our solar system. New research now suggests the ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets can ...

"A planet orbiting not just a binary, but a binary brown dwarf, as well as being on a polar orbit, is rather incredible and exciting." When you purchase through links on our site, we may earn an ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

When my colleagues and I send them out to explore our solar system, it's important for us to understand the 3D map of our space neighborhood.
