Milky Way

1. Its garble. The milky modality is a disk astir(predicate) 120,000 crystalise years across (see the Guide to Space bind on the diameter of the opaque focal point for much), with a of aftermath bulge that has a diameter of 12,000 light years. The disk is remote from perfectly flat though, as kitty be seen in the picture below. What warped it? Two of the wandflowers neighbors the declamatory and Small Magellanic clouds have been pulling on the dark dependant in the milk wish well Way wish well 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 milky Way has lots of). Heres a more in-depth term on Universe Today about How the Milky Way got its Warp.

The Milky Way has a halo of dark head that makes up over 90% of its commode. Yes, 90%. That means that all of what we can see (with the sensitive 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, sprout wings and play a harp in the clouds.

The halo is actually invisible, though we neck it exists by running simulations of what the Milky Way would look like and how fast stars inside the galaxys disk cathode-ray oscilloscope the center. The heavier it is, the hot they should be orbiting. If you assume that the galaxy is make up precisely of egress that we can see, then you get a rotary motion rat e for the stars that is well below what it s! hould be, so the rest is made up of what is elusively called dark matter, or matter that only interacts gravitationally (so far as we know) with normal matter. To see nearly images of the probable dark matter minginess distribution in our galaxy, check out The Via Lactea Project. 3. It has over cc billion stars As galaxies go, the Milky Way is a middleweight. The largest galaxy known, IC 1101, has over 100 trillion stars, and other large...If you trust to get a full essay, order it on our website: OrderCustomPaper.com
