NGC 2070 (also known as ESO 57-EN6 ) is an emission nebula in the constellation Golden Fish . Also known as Tarantula .

Content

Features

The nebula belongs to the satellite galaxy of the Milky Way - the Large Magellanic Cloud . It is a vast area of ionized hydrogen , where processes of active star formation occur.

This object is one of those listed in the original edition of the New General Catalog .

The huge stars of the nebula are powerful sources of radiation that blows giant bubbles from interstellar gas and dust. Some of the stars exploded in supernovae , causing the bubbles to be illuminated by X-rays .

In the center of the nebula is a small cluster of stars R136 , at the junction of three bubbles. These stars are the result of star formation processes, their age is estimated at approximately two million years. In addition, the nebula contains a supermassive star RMC 136a1 with a mass of 315 ^[1] ^[2] solar (this is the most massive star discovered as of July 21 , 2011 )

Along the edge of the nebula are relatively young globular star clusters, as well as groups of young stars that are part of the superassociation.
