Until recently, there were only ten known stars on trajectories that will allow them to escape the Milky Way galaxy, thrown astray by powerful supernova explosions. A new study using data from ESA's Gaia survey this June ...

A team of astronomers has claimed that observations of a sun-like star orbiting a small black hole might actually be the indication of something far more exotic—the existence of a boson star, a star composed entirely of ...

One of the most intriguing predictions of Einstein's general theory of relativity is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can escape them.

Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers ...

Roughly a half-century ago, astronomers realized that the powerful radio source coming from the center of our galaxy (Sagitarrius A*) was a "monster" black hole. Since then, they have found that supermassive black holes (SMBHs) ...

At the center of most galaxies are black holes so massive—up to several billion times the mass of our sun—that they have earned the descriptor "supermassive." Compare this to your run-of-the-mill stellar-mass black hole, ...

In the past, we've reported about how the Roman Space Telescope is potentially going to be able to detect hundreds of thousands of exoplanets using a technique known as microlensing. Exoplanets won't be the only things it ...
