How far apart are M81 and M82?

12 million light-years M81 (on the left), a "face-on" spiral galaxy, and M82 (on the right), seen "edge-on," are a pair of galaxies in the constellation Ursa Major, near the "Big Dipper." The apparent separation of the galaxies is 31 arc-minutes but at a distance of 12 million light-years, their actual distances from each other is 150,000

In respect to this, what happened to m81 and m82?

Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays. Subsequently, can you see m82 with binoculars? Two other neighboring galaxies, M81 and M82, may be seen in binoculars on a dark, clear spring evening. They are not far from the "bowl stars" of the Big Dipper, high up in the northern sky in mid-evening.

What did the universe look like in the beginning?

In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter ? the quarks and electrons of which we are all made. Is bodes galaxy visible to the naked eye? Bode's Galaxy can easily be seen in binoculars and amateur telescopes, but is not visible to the unaided eye unless viewing conditions are exceptionally good. The structures within M81 can be seen in 8-inch or larger telescopes.

What if a comet hit the Sun?

Can Comets destroy the sun? Nothing will happen. The mass and the heat of the Sun are of such magnitude that even the biggest object in the solar system, Jupiter, hitting the Sun would cause just a momentary hiccup, and comets are actually tiny objects in the scale of the solar system. Where are comets located? Comets are mostly found way out in the solar system. Some exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt. We call these short-period comets. They take less than 200 years to orbit the Sun.

Comets orbit the Sun just like planets and asteroids do, except a comet usually has a very elongated orbit. As the comet gets closer to the Sun, some of the ice starts to melt and boil off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma.
