The supermassive black hole appears to grow like a small star
Artist’s impression: A spiral wind helps the supermassive black hole in the galaxy ESO320-G030 grow, aided by the magnetic field. […]

“Halo Drive” can achieve relativistic speeds by shining light around a black hole
If we ever want to explore the galaxy (let alone the rest of the universe) we have a speed problem.

The CERN experiment helps narrow the hunt for dark matter
Over the past half century, astronomers have faced an embarrassing problem: galaxies rotate too fast. When astronomers measure the velocities
How neutron stars ‘playing with the cold’ can unlock exotic physics
Scientists have found that three neutron starsborn in the fires of other exploding stars, have cooled surprisingly quickly, bringing us
‘Immortal’ stars at the center of the Milky Way may have found an endless source of energy, study suggests
A special group of stars orbiting the violent center of the Milky Way could become “immortal” by constantly capturing and
