Tarantula Nebula

Also known as 30 Doradus and NGC 2070, the Tarantula Nebula is situated in the Large Magellanic CLoud, a small galaxy that orbits our Milky Way. The star-forming region is about 1,000 light years across and is the largest emission nebula known so far. It lies about 170,000 light years away, and can be seen in the constellation Dorado in the southern hemisphere. It has a mass half a million of our sun. It contains some of the hottest and brightest stars that we know of. If it were as far away as the Orion Nebula, which is visible from Earth at night, it would take up an area twice the size of the Big Dipper, and would be so bright that it would be visible during daytime.
