One of them might have a smaller "hidden friend."

Our galaxy might have two — two! — black holes at its center

Buddy System

The Milky Way might be home to two black holes and not just one — and researchers have a plan for detecting Sagittarius A*'s "hidden friend."

Our Galaxy Might Have — Two! — Black Holes at Its Center

And scientists think they know how to find out for sure.

The researchers estimate it could've lasted for some 300,000 years.

3.5 million years ago, our galaxy was rocked by an explosion

Big Burp

According to a new study, the center of the Milky Way galaxy exploded in a huge flare-up of hot gas. And an explosion might explode again in the future.

3.5 Million Years Ago, Our Galaxy Was Rocked by an Explosion

And it could happen again.

The flare up could have been caused by a nearby celestial object being swallowed up.

The Milky Way's supermassive black hole just did something wild

Flare Up

Astronomers observed the supermassive black hole at the centre of the Milky Way called Sagittarius A* flare up, growing 75 times brighter than usual.

The Milky Way’s Supermassive Black Hole Just Did Something Wild

Why did the center of the Milky Way just light up to the brightest levels we've ever observed?

Here's the best-ever image of the black hole devouring our galaxy

Black Hole Sun

Researchers have captured the best-ever image of Sagittarius A*, the supermassive black hole at the center of the Milky Way.

Here’s the Best-Ever Image of the Black Hole Devouring Our Galaxy

"We should not fear the supermassive black hole."

New image confirms a black hole is swallowing our galaxy

It's Really There

New evidence confirms the existence of Sagittarius A*, a black hole long assumed to reside at the center of the Milky Way.

New Image Confirms a Black Hole is Swallowing Our Galaxy

Don't worry, it's only devouring our galaxy slowly.

It was uncovered in a cloud of toxic gas 200 million light-years away.

Newly discovered black hole may be the first of its kind ever detected

Hard Science

Japanese astronomers have found evidence of a cloud-dwelling intermediate-size black hole near the center of the Milky Way galaxy.

Newly Discovered Black Hole May Be the First of Its Kind Ever Detected

And it may be nearly as old as the Milky Way itself.

This telescope could produce the first image of a black hole.

We May Finally Get a Picture of a Black Hole

We know they are out there, but it’d be nice to see one for ourselves.

Off World

Astronomers may have just found the very first intermediate-mass black hole in the Milky Way.

We Just Found Evidence of the Second Largest Black Hole in our Galaxy

The Event Horizon Telescope is set to give us our first-ever image of the "point of no return" surrounding a supermassive black hole.
