Is the Milky Way in the center of a void?
As with other voids, it is not completely empty but contains the Milky Way, the Local Group, and a larger part of the Laniakea Supercluster. The Milky Way is within a few hundred million light-years of the void’s center.
Will we get sucked into the center of the Milky Way?
Black holes, even the one at the center of our galaxy, are very small. Only if you get very close to a black hole’s event horizon does it start pulling everything in. So no, most of the galaxy will not eventually fall into the hole.
Why aren’t we being sucked into the black hole in the Milky Way?
From a great distance, a black hole is just like any other object with the same mass. It doesn’t have any magical power to suck things in. Its gravity is just like the gravity of anything else. It wouldn’t get sucked into the black hole.
What is the biggest structure in the universe?
Hercules-Corona Borealis Great Wall
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure.
What universe are we living in?
Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
What is at the center of the Milky Way galaxy?
At the center of the Milky Way Galaxy is a supermassive black hole. The region where the black hole is located is called Sagittarius A* (prounounced “A star”). The black hole itself cannot be observed partly because it emits no light, and partly because there is too much gas and dust between us and that region for us to be able to observe it.
What would the night sky look like in the Milky Way?
The night sky would be so bright, that it would not seem much different than day. The Sun and Solar System are within the 1,000 light year thick disk, and we are only about 95 light years from the central plane. Artist’s impression of the Milky Way Galaxy. The disk of our galaxy appears blue because it has a large proportion of young,
How many light years across is the Milky Way?
The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way. Parallaxes give us distances to stars up to perhaps a few thousand light years.
Is the Milky Way spiral or elliptical?
The concentration of stars in a band adds to the evidence that the Milky Way is a spiral galaxy. If we lived in an elliptical galaxy, we would see the stars of our galaxy spread out all around the sky, not in a single band. An all-sky image shows the flat plane of the Milky Way galaxy.
