"It's a huge difference." The two glowing eyes … Also, a dust lane can be seen in the shape of an inclined disk. This massive star is housed in the NGC 3603 nebula, in the Carina spiral arm of the Milky Way, which is known as one of the luminous and most compact star clusters. The star HD … The very massive star R136a1 lies in this star-forming region in the Large Magellanic Cloud (a neighbor galaxy to the Milky Way). In comparison, the largest known galaxy, called IC 1101, is 50 times larger and about 2,000 times more massive than our galactic home. From colliding galaxy to interacting galaxy, here is a list of 10 most amazing galaxies in the universe, Amazing Galaxies In The Universe 1. The rendering shows that star formation in the galaxy is lighting up the surrounding gas. The largest and most massive star clusters are the globular clusters, so called because of their roughly spherical appearance. Most of the most massive stars known to date lie in the Large Magellanic Cloud, a satellite galaxy to the Milky Way. This behemoth galaxy cluster … It is … The quasar is an incredible 1,000 times more luminous than our entire Milky Way galaxy, and is powered by the supermassive black hole, which weighs in … It has a bright central nucleus and a large central bulge. However, the Milky Way has its own contenders. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. This is an artist's rendering of what a massive galaxy from the early universe might look like. The Sombrero Galaxy. NASA/ESA/STScI The star R136a1 currently holds the record as the most massive star known to exist in the universe . A massive galaxy cluster known as SDSS J1038+4849 looks like a smiley face in an image captured by the Hubble Telescope. The most massive conglomeration of galaxies ever spotted in the early universe has been found, astronomers say. "If you look at normal galaxy clusters, the central, most massive galaxy is typically forming stars at a rate of one new star every few years," McDonald said. The Milky Way galaxy is already mind-bendingly massive, stretching 100,000 light-years from end to end, containing approximately 200 billion stars, and … The Galaxy contains more than 150 globular clusters (the exact number is uncertain because of obscuration by dust in the Milky Way band, which probably prevents some globular clusters from being seen). It is also known as M104 or NGC 4594.
