The universe as we know it is made up of three spatial dimensions, right? But some physics models suggest the existence of extra dimensions that we can’t perceive. In an effort to find evidence of these dimensions, researchers have studied gravitational waves and come up empty.

Discoveries that back up Einstein’s theory of general relativity are still being made. The latest comes from the Max Planck Institute, where astronomers have watched how the supermassive black hole at the center of the Milky Way pulls and stretches the light from a star as it makes its closest pass.

Astronomers have long proposed that there must be intermediate-mass black holes (IMBHs) in space. Now, scientists from the University of New Hampshire have captured the best evidence so far of the existence of these mysterious middleweights, as one emerges from the dark to snack on a star.

Astronomers have detected some strange objects at the center of the Milky Way. They look like ordinary clouds of gas, but seem to have a solid core that keeps them together. The truth may lie somewhere in-between. These G-objects, as they’re known, seem to be stars hiding under puffy shrouds of dust

In August 2017, astronomers observed a collision between two neutron stars so powerful it produced gravitational waves, flares in visible light, radio waves, x-rays and a gamma ray burst. Now that things have quietened, astronomers have studied the strange object created in the cosmic collision.

Astronomers at Australian National University have spotted a black hole so bright that were it in our home galaxy, it would outshine all the stars in the sky. This supermassive monster also happens to be the fastest-growing black hole ever seen, devouring the equivalent of the Sun every two days.

Scientists have long searched for proof of the decades-old theory that black holes surround the supermassive black hole at the heart of our galaxy. By tweaking their approach just a little, astronomers have now turned up the first direct evidence that they do in fact exist.

Black holes can be anywhere from a few times the mass of the Sun up to millions of times that, but some even bigger than that. A new study of data gathered by NASA’s Chandra X-ray telescope has found these so-called “ultramassive” black holes may be larger and more common than we thought.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) observatory in Chile have imaged a very active black hole at the center of spiral galaxy M77, which is apparently feasting on the universe’s largest donut.

Gamma ray bursts are mysterious signals blasting in from the deepest reaches of space, and we still don’t have much of an idea about what causes them. In order to help unlock the secrets, researchers have managed to recreate mini gamma ray bursts in the lab for the first time.
