Probing Variable Black Holes
Artist impression of a black hole feeding off its companion star... and a rogue Higgs particle (ESO/L. Calçada/Particle Zoo) Black holes are voracious eaters. They devour pretty much anything that...

I Wish Office Work Was This Interesting
Having just stumbled around the space blogs, I was enthusiastic that I would find some inspiration toward my next Astroengine.com article. Along the way, I found this rather entertaining short film on...

Forget Black Holes, Let’s Look For Black Rings
Black holes are as extreme as anything can get. When a massive structure can no longer sustain its own gravity, it will collapse to a point known as a singularity. For example, a massive star after it...

The Event Horizon Telescope: Are We Close to Imaging a Black Hole?
A modelled black hole shadow (left) and two simulated observations of Sgr A* using a 7-telescope and 13-telescope array (Fish & Doeleman) All the evidence suggests there is a supermassive black...

The Naked Singularity Recipe: Spin a Black Hole, Add Mass
The event horizon of a black hole is the point of no return. If anything, even light, strays within the bounds of this gravitational trap, it will never escape. The event horizon is what makes a black...

Unexpectedly Large Black Holes and Dark Matter
The M87 black hole blasts relativistic plumes of gas 5000 ly from the centre of the galaxy (NASA) I just spent 5 minutes trying to think up a title to this post. I knew what I wanted to say, but the...

The LHC Black Hole Rap… Best Yet
Released in December 2009, Kate McAlpine (a.k.a. AlpineKat) put together the rather fun “Black Hole Rap” in an effort to trivialize the disinformation being peddled about the Large Hadron Collider...

How are Black Holes Used in the Movies?
Source: Graph Jam I mean, is the spaghettification of John Cusack using awesome 2012 doomsday graphics too much to ask? Instead of an improbable alien spacecraft appearing over the White House, why not...

Black Holes, Aurorae and the Event Horizon Telescope
My impression as to how a black hole 'aurora' might look like near an event horizon (Ian O'Neill/Discovery News) Usually, aurorae happen when the solar wind blasts the Earth’s atmosphere. However,...

This Black Hole Keeps Its Own White Dwarf ‘Pet’
The most compact star-black hole binary has been discovered, but the star seems to be perfectly happy whirling around the massive singularity twice an hour. Credits: X-ray: NASA/CXC/University of...

Plasma ‘Soup’ May Have Allowed Ancient Black Holes to Beef up to Supermassive...
How ancient supermassive black holes grew so big so quickly is one of the biggest mysteries hanging over astronomy — but now researchers think they know how these behemoths packed on the pounds. John...

We’re Really Confused Why Supermassive Black Holes Exist at the Dawn of the...
ESO Supermassive black holes can be millions to billions of times the mass of our sun. To grow this big, you’d think these gravitational behemoths would need a lot of time to grow. But you’d be wrong....

Beyond Spacetime: Gravitational Waves Might Reveal Extra-Dimensions
NASA (edit by Ian O’Neill) We are well and truly on our way to a new kind of astronomy that will use gravitational waves — and not electromagnetic waves (i.e. light) — to “see” a side of the universe...
