Colossal X-ray "chimneys" discovered at center of the Milky Way

Michael Irving March 20, 2019

It's hard to really understand the large-scale structure of the Milky Way. Now, astronomers have peered towards the center of the galaxy using the ESA's X-ray telescope XMM-Newton, and discovered two colossal "chimneys" pumping huge amounts of energy and gas out into intergalactic space.

Massive hypervelocity star escaping Milky Way hints at presence of hidden black hole

Anthony Wood March 13, 2019

A team of astronomers has managed to find the origin of an enormous star that is currently barreling out of the Milky Way having escaped from one of our galaxy’s spiral arms. The discovery challenges the theory that such stars come from the galactic center.

Doomed, rare black hole spotted near the center of the galaxy

Michael Irving March 3, 2019

Black holes tend to fall into two categories: fairly small or supermassive. It’s long been believed that there should be a middle class, and in recent years astronomers have found evidence of these “intermediate mass” black holes. Now a Japanese team has located one near the center of the Milky Way.

Sharper images of a supermassive black hole reveal new secrets

Michael Irving January 23, 2019

A team of astronomers has used a global array of telescopes to peer through the fog and capture some of the clearest radio images yet of Sagittarius A*, the supermassive black hole at the center of the Milky Way. And it may indicate that the object just happens to be pointing directly at Earth.

Astronomers witness strange space "Cow" give birth to a black hole

Michael Irving January 10, 2019

In June 2018, a bright light burst in Northern Hemisphere skies. At first it looked like any other supernova, but soon turned out to be far weirder. Known as AT2018cow (or “The Cow”), astronomers now believe they’ve captured an unprecedented look at the birth of a black hole or a neutron star.

Revolutionary new telescope picks up 13 fast radio burst signals, including one repeater

Michael Irving January 9, 2019

The CHIME telescope has picked up 13 unexplained radio signals coming from beyond the Milky Way. These fast radio bursts are part of one of the strangest mysteries of modern astronomy, but the new detections could help unlock their source, thanks to a rare one that seems to be repeating.

Most powerful gravitational waves event stands out among four new detections

Michael Irving December 3, 2018

Gravitational waves are ripples in the very fabric of spacetime, caused by some of the biggest cataclysms in the cosmos. Now, an international team of scientists has presented the full catalog of these events, gathered over the last few years across two observation runs.

Hubble snaps clearest ever shots of cataclysmic cosmic collisions

Michael Irving November 11, 2018

Galaxies smash into each other on a pretty regular basis, usually merging together. Using data and observations from Hubble and the Keck Observatory, astronomers have now imaged the late stages of this incredibly slow process for the first time.

Astronomers have observed pairs of supermassive black holes closer to colliding than ever before

How dying stars could reignite with help from enigmatic class of black hole

Michael Irving October 31, 2018

A white dwarf is one of the last stages of life for stars of a certain size, and it’s all downhill from there. But supercomputer simulations run by astronomers at LLNL suggest that these dying stars could be reignited by a close encounter with an enigmatic class of black hole.

Can we use gravitational waves to detect hidden dimensions?

Michael Irving September 16, 2018

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.
