What does ngc2237 mean in love?

Ngc2237 stands for the rose in love, which is originally part of the Rose Nebula. The Rose Nebula is a huge spherical ionized hydrogen region (circular in appearance) located in the constellation Unicorn, which is near the end of a huge molecular cloud in the Milky Way.

Rose nebula NGC 2237 is a large emission nebula with a distance of 3000 light years. There is an open cluster numbered NGC 2244 in the center of the nebula, and the star wind from the star cluster has blown a big hole in the center of the nebula. These stars were formed by the clouds around them about 4 million years ago, and there is an isolation layer of dust and hot clouds on the edge of the hole. ?

Extended data

In 20 10, NASA detected the youngest cluster in the central area of Kirin constellation through the picture of "Rose Nebula". These massive young stars will produce a lot of ultraviolet rays, release strong stellar winds and erode the nearby gas and dust, which is the origin of the central cavity structure in the center of the "Rose Nebula".

In addition to the Rose Nebula, there are other beautiful nebulae in the universe, among which Andromeda Nebula, also called Andromeda, is a spiral galaxy with a huge disk structure in the direction of Andromeda, which looks like a spindle-shaped oval spot in the sky.
