In the last two years, astronomers discovered several exoplanets in binary systems: two stars locked in mutual orbit. These systems come in several types, with the planet orbiting one or both stars.

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of ...

Especially with the discovery of Pluto’s fifth moon in 2012, the distant icy planet and its largest moon Charon has gotten a lot of attention. You’ve undoubtedly heard Pluto referred to as the ...

While astronomers studied the asteroid belt in between Mars and Jupiter with the Hubble Space Telescope over the course of several years, they came across a rather peculiar finding in a binary ...

New research finds that ‘Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system. “It’s remarkable that we’ve now seen for the ...

A team of astronomers led by Paulo Cortes, a scientist with the U.S. National Science Foundation National Radio Astronomy Observatory and the Joint ALMA Observatory, have made a groundbreaking ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...

M33 X-7 contains a massive black hole orbiting a large star in a surprisingly close orbit. The star is dimmer than expected due to its rapid mass gain and viewing angle. A new model explains the ...

In a recent study accepted to Astronomy & Astrophysics, a team of researchers use a combination of space- and ground-based telescopes to examine a binary star system (two stars orbiting each other) in ...

Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...

Asteroids with moons, which scientists call binary asteroids, are common in the solar system. A longstanding question has been how the majority of such moons are formed. In this week’s issue of the ...
