What is the nucleus of our galaxy?
What is the nucleus of our galaxy?
The very center of our galaxy is called the nucleus, or central bulge. By observing X-ray emissions, radio maps, and infrared, we have seen that the center of the galaxy contains a lot of stars. But it also contains Sagittarius A*, or Sgr A*. A very powerful radio source lying in the galactic nucleus.
What is a double nucleus galaxy?
The double nucleus is actually an elliptical ring of old reddish stars in orbit around the black hole but more distant than the blue stars. When the stars are at the farthest point in their orbit they move slower, like cars on a crowded freeway. This gives the illusion of a second nucleus.
How many light years away is Andromeda?
2.537 million light years
Andromeda Galaxy/Distance to Earth
Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see. At 2.5 million light-years, it’s the most distant thing most of us humans can see with the unaided eye.
Which type of galaxy has a nucleus made up of bright stars?
Spiral galaxies Spirals

What is the Earth’s galaxy called?
The Milky Way
The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.
Which is the largest known galaxy?
IC 1101
It’s difficult to characterize what the largest galaxies are, because they don’t really have precise boundaries, but the largest galaxies we know of are millions of light-years across. The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive.
Is Andromeda Galaxy getting closer?
The Andromeda Galaxy (M31) is indeed approaching us, by about 300 kilometers (190 miles) per second measured with respect to the Sun. The two galaxies will merge a few billion years from now. This is normal. Neighboring galaxies are bound into clusters by their mutual gravitational attraction.
