Here's How Black Holes Turn On The Lights In The Universe Around Them

Despite their popular reputation as dark inescapable pits, black holes really put out a lot of energy. They thrust out jets of matter. They get matter to heat up through friction as it swirls around them. And, in some cases, they contribute to bursts of incredibly high energy photons, thanks to a phenomenon first encountered in the 1920s here on Earth.

The Blood Moon Was Recorded Back In 19th Century Thailand

This past Monday, people from around the world aimed their cameras upwards in hopes of catching a glimpse of the “blood moon” lunar eclipse. But as this 19th century manuscript shows, it’s a phenomenon that’s been chronicled long before the advent of camera phones and telescopic lenses.

Australia Won't Get The Super Blood Moon Eclipse, But You Can Still Watch It Live Right Now

Today people in North and South America, Europe, Africa and parts of Asia and Pacific will witness a rare event, not to be seen again until 2033. This is the so-called ‘Super Blood Moon’, a phenomenon where the moon appears much larger than it normally does, and also acquires an eerie red-orange tint. Unfortunately Australia misses out on this astronomical event, but thanks to the wonders of live streaming you can still catch all the action from halfway across the world.

Scientists Discover Weather On Rosetta's Comet

Earth’s favourite comet is chock full of surprises. The latest? Weather, of sorts. According to research published this week in Nature, Comet 67P has a small weather system driven by an intense day-night cycle.

These Are Some Of The Best Astronomy Pictures Of The Year

Image Cache: Last night, the Insight Astronomy Photographer of the Year competition announced its winners. The results, as you might expect, are astronomical. Here are a few of our favourites.

Two Black Holes Are About To Smash Into Each Other

Three and a half billion light years away in the Virgo constellation, two supermassive black holes are on the verge of smacking into one another. In 100,000 years, their cosmic collision will send ripples across the fabric of spacetime.

Where In Our Galaxy Are All The Aliens?

There may be billions of habitable worlds throughout the Milky Way, but where are the radio-blasting, starship-sailing aliens? Where are our cosmic Snapchat buddies? If they exist, they’re probably thousands of light years away from us, nestled somewhere toward the center of our Galaxy.

A Lava Ocean On Io Could Mean Better Prospects For Alien Life

Io is an eruptive mystery. Based on scientific models, the tiny Jovian moon’s volcanoes flare up in the “wrong” places. How could that be? Well apparently, our models didn’t account for a massive subsurface ocean of lava.

How To Spot A Black Hole

You don’t need to be a professional astronomer to find black holes. Here’s how you can spot one, using just your laptop or phone.

This Is The Oldest Galaxy We've Found So Far

Astrophysicists at Caltech say they have detected the oldest, most distant galaxy known so far. It’s 13.2 billion years old — just over half a billion years younger than the universe itself — and the discovery may change what astrophysicists know about the early history of the universe.
