What is the closest galaxy to our own?

Canis Major Dwarf Galaxy

Who is our nearest Neighbour in the galaxy?

What is our galactic cluster called?

Virgo Cluster

What’s bigger than a galaxy cluster?

So what’s larger than a galaxy cluster? A supercluster, of course. Superclusters are collections of clusters connected by great cosmic filaments of dark-and-normal matter, whose gravitation mutually attracts them towards their common center-of-mass.

What is the largest galaxy in the universe?

Largest galaxy: IC 1101 Our Milky Way galaxy is around 100,000 light-years across, but that’s fairly average for a spiral galaxy. In comparison, the largest known galaxy, called IC 1101, is 50 times larger and about 2,000 times more massive than our galactic home.

Is IC 1101 a spiral galaxy?

IC 1101 is a supergiant elliptical galaxy located in the constellation Virgo. With a radius of about 2 million light years and home to 100 trillion stars, it is one of the largest galaxies known, as well as one of the most luminous. They are believed to be the transitional type between spiral and elliptical galaxies.

How far is IC 1101 from earth?

1.045 billion light years

Why is a telescope like a time machine?

Because light takes time to travel from one place to another, we see objects not as they are now but as they were at the time when they released the light that has traveled across the universe to us. Astronomers can therefore look farther back through time by studying progressively more-distant objects.

What is the biggest black hole in the universe?

Currently the largest known black hole, powering the quasar TON 618, has a mass of 66 billion solar masses. TON 618’s enormous bulk led scientists to speculate whether or not even larger black holes exist, and if there is any upper limit to their sizes.

How big is IC 1101?

1.9569 million light years

What kind of galaxy is IC 1101?

supergiant elliptical galaxy

What happens when the Milky Way collides with Andromeda?

That said, the stars in both the Andromeda galaxy and our Milky Way will be affected by the merger. The Andromeda galaxy contains about a trillion stars. The Milky Way has about 300 billion stars. Stars from both galaxies will be thrown into new orbits around the newly merged galactic center.

Will the Milky Way collide with the Andromeda Galaxy?

Previous simulations have suggested that Andromeda and the Milky Way are scheduled for a head-on collision in about 4 billion to 5 billion years. But the new study estimates that the two star groups will swoop closely past each other about 4.3 billion years from now and then fully merge about 6 billion years later.

How long would it take to reach Andromeda?

2.5 million years
