This beautiful galaxy is being warped by its hungry supermassive black hole

This stunning image of a distant galaxy was captured by the ground-based Nicholas U. Mayall 4-meter Telescope in the Arizona-Sonoran Desert. To capture distant objects in such detail, the telescope has a Mosaic camera that combines multiple captures into one image.

This spiral galaxy is named Messier 106, or NGC 4258, and despite its apparently tranquil appearance, it is the site of a hungry, hungry black hole. Almost all galaxies have an enormous supermassive black hole at their center, and Messier 106 is no exception.

Its supermassive black hole is 40 million times the mass of our sun, and it is particularly active. It drags in large amounts of dust and gas, chowing down on far more matter than other supermassive black holes like the one at the center of our galaxy. And the black hole in Messier 106 spins as well, rotating with such force that it actually warps the disk of gas that surrounds it.

This warping also created streamers of gas that burst from the center of the galaxy, which you can see as red lines. These appear like extra spiral arms, as most spiral galaxies have just one pair of arms which consist of groups of stars. The red “arms” in Messier 106 are made up of gas rather than stars, but they add to the unusual features of this active galaxy.

This galaxy is very large, at more than 130,000 light-years across. It is similar in terms of both size and brightness to our neighboring galaxy, the Andromeda galaxy, which is visible with the naked eye. But because Messier 106 is 10 times more distant than Andromeda, it appears very small in the night sky. However, it can be spotted using a telescope, which makes it a favorite target for amateur astronomers.

Messier 106 is also of interest to cosmologists, as it is used in measuring the size of the universe as part of a measurement called the cosmic distance ladder.

How James Webb will peer through a dusty cloud to study supermassive black hole
Centaurus A sports a warped central disk of gas and dust, which is evidence of a past collision and merger with another galaxy. It also has an active galactic nucleus that periodically emits jets. It is the fifth brightest galaxy in the sky and only about 13 million light-years away from Earth, making it an ideal target to study an active galactic nucleus – a supermassive black hole emitting jets and winds – with NASA's upcoming James Webb Space Telescope.

When the James Webb Space Telescope launches later this year, it'll be the most complex space observatory in the world. Now, NASA has shared a glimpse into the kind of work that it will be able to perform in a profile of research that will be conducted on the nearby galaxy Centaurus A.

See a map of 25,000 supermassive black holes in distant galaxies
Preview of a Sky map showing 25,000 supermassive black holes.

It might look like a map of stars, but that's not what is shown in the image above. Instead, each dot on this map of the night sky represents an enormous black hole called a supermassive black hole, each in a different distant galaxy.

Six galaxies trapped in cosmic web could explain supermassive black hole growth
This artist’s impression shows the central black hole and the galaxies trapped in its gas web.

Astronomers know that at the heart of most galaxies lies an enormous monster: A supermassive black hole, millions of times the mass of our sun. But they are still learning about how these beasts form and grow to such a large size.

Now, a group using the Very Large Telescope (VLT) has found a group of six galaxies trapped in a cosmic "spider's web" around a supermassive black hole, and investigating this oddity could help explain the formation of these colossal black holes.
