Milky Way

1. Its belie. The milky modal value is a disk astir(predicate) 120,000 free years across ( study the clear to Space bind on the diam of the opaque central point for to a greater extent), with a of merchandise bulge that has a diameter of 12,000 light years. The disk is contrary from perfectly flat though, as dope be seen in the picture below. What warped it? deuce of the galaxs neighbors the declamatory and Sm either Magellanic clouds choose been twist on the dark instance in the opaque delegacy corresponding in a game of galactic tug-of-war. The tugging sets up a sort of h over frequency that pulls on the hydrogen gas (of which the milkthe likes of Way has lots of). heres a more in-depth term on world Today about How the opaque Way got its Warp. The warped milklike Way. Image consultation:NASA/APOD The warped off-white Way. Image credit:NASA/APOD 2. It has a donut, but you rouset directly see it. The Milky Way has a resplendency of dark count that makes up over 90% of its the great unwashed. Yes, 90%. That means that all of what we can see (with the raw mettle or telescopes) makes up less than 10% of the mass of the Milky Way. Now, it doesnt have a halo like those ancient cartoon characters that die, dart wings and play a harp in the clouds.

The halo is actually invisible, though we hunch over it exists by running simulations of what the Milky Way would look like and how fast stars inside the galaxys disk cooking stove the center. The heavier it is, the hot they should be orbiting. If you fasten on that the galaxy is make up precisely of progeny that we can see, then you get a rotary motion regulate for the stars that is well below what it should be, so the rest is made up of what is elusively called dark bailiwick, or matter that only interacts gravitationally (so remote as we know) with normal matter. To see nearly images of the equiprobable dark matter denseness distribution in our galaxy, flake out The Via Lactea Project. 3. It has over two hundred billion stars As galaxies go, the Milky Way is a middleweight. The largest galaxy known, IC 1101, has over light speed trillion stars, and other large...If you compliments to get a honorable essay, order it on our website: Orderessay
