Interesting Facts about the Pinwheel Galaxy, Star Maker Galaxy

As you know, throughout the universe there are many other galaxies that are no less large and beautiful than ours, the Milky Way galaxy. There is a galaxy closest to us, the Andromeda Galaxy, that is known to all astronomers. Apart from Andromeda, it turns out that there is another galaxy, namely the Pinwheel Galaxy which of course also has some interesting facts.

Do you know what Pinwheel Galaxy is yet? If not, let's look at Interesting Facts about the Pinwheel Galaxy, Star Maker Galaxy.

The Origin of the Pinwheel

From photos taken by the Hubble telescope, the shape of this Pinwheel galaxy is very unique. It looks a lot like a giant Pinwheel with bright arms sticking out from the middle. Did you know that this Pinwheel shape doesn't just appear.

The origin of this Pinwheel shape is due to strong gusts of wind, dust, and gas ejected from 2 stars orbiting each other. Due to the strong attraction of the two stars, the three elements intertwine and collide to form the Pinwheel arm.

Pinwheel Galaxy location close to Earth

Unlike other galaxies that are very far away, the Pinwheel Galaxy is relatively close to Earth. The distance is about 21 million light years. The Pinwheel Galaxy is 2 times larger than the Milky Way galaxy.

In this Pinwheel galaxy, it is estimated that there are more than 1 trillion living stars. The Pinwheel Galaxy is a member of the constellation Ursa Major in outer space. The Pinwheel Galaxy is much larger than the Milky Way galaxy. with a diameter of up to 170,000 light years.

The Pinwheel Galaxy was first discovered by French astronomer Pierre Mechain and verified by Charles Messier. The scientific name for the Pinwheel Galaxy is Messier 101.

Star Maker Galaxy

Well, the Pinwheel Galaxy is a star-printing galaxy in the universe. Approximately this Pinwheel galaxy has produced approximately 3,000 new stars in the region called the HII region in the Pinwheel arm of this galaxy.

In this section, the hydrogen content is so large that stars are very easy to make there. Hydrogen itself is the main component of star-forming in outer space besides helium.

Supernovas Often Occur in Pinwheel Galaxies

Because the Pinwheel galaxy has such a large number of stars, supernova explosions often occur there. Supernova itself is an explosion that occurs when a star dies. The force of the explosion was so strong that it could sometimes be felt in the surrounding galaxy.

Scientists note that at least 4 supernovas have occurred in the Pinwheel Galaxy, the last one occurred in 2011. Meanwhile, in 2015 the Pinwheel Galaxy formed a Red Nova, which is an explosion caused by 2 colliding stars.

Galaxies Without Black Holes

Usually galaxies in the universe have at least one black hole, either at the center or around it. In fact, it is not uncommon for a galaxy to have a deadly supermassive black hole.

But this Pinwheel Galaxy is very unique. How not unique, this Pinwheel galaxy does not have a black hole at its center. It only has a super bright X-ray beam. This light is produced by dying stars and other matter heating up.

The center of the galaxy is heavier than the sun

The center of the Pinwheel Galaxy is a small mound as the center of the windmill. The weight of this mound is estimated to be 3 times the mass of the sun!

There is one unique fact about the center of this Pinwheel galaxy. Unlike the Pinwheel galaxy arm which can make stars, the center of the Pinwheel galaxy cannot actually produce any stars at all.


The vastness of this universe, no one knows. That's why humans with their technological sophistication are constantly trying to find out the hidden facts that are out there. What do you think, is it important to make astronomical discoveries like the Pinwheel Galaxy?

And by the way, those are some interesting facts about Interesting Facts about the Pinwheel Galaxy, Star Maker Galaxy.
