In the subsequent analysis, we will refer to the primary as D9a, whereas the secondary companion will be denoted as D9b. With the binary orbiting Sgr A*, this three-body system is divided into an ...

Every galaxy has a supermassive black hole at its center, much like every egg has a yolk. But sometimes, hens lay eggs with two yolks. In a similar way, astrophysicists like us who study supermassive ...

The NASA Double Asteroid Redirection Test (DART) spacecraft successfully struck Dimorphos, the moon of the binary asteroid (65803) Didymos, on Sept. 26, 2022 1. Prior to colliding with the surface, ...

D9, as the newly discovered binary star is called, was detected just in time: it is estimated to be only 2.7 million years old, and the strong gravitational force of the nearby black hole will ...

Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many ...

It may not be anything like Tatooine of Star Wars, but this discovery is still incredible. We’ve found a frozen, rocky planet orbiting one of its two parent binary stars in a stable Earth-like orbit.

How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...
