Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

The supermassive black hole at the center of our Milky Way galaxy is associated with wanton destruction, but a recent discovery throws that assumption into question. A team of international ...

Interacting binary stars, a class of stellar systems consisting of two gravitationally bound stars, exhibit a rich diversity of phenomena driven by mass transfer and angular momentum exchange. In many ...

An international team of researchers led by PD Dr Florian Peißker has found the first binary star in the immediate vicinity of the supermassive black hole Sgr A* (Sagittarius A star) at the centre of ...

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.
