Just lately, the James Webb Area Telescope (JWST) took a surprising picture of the star cluster generally known as Westerlund 2, positioned in a stellar nursery referred to as Gum 29 discovered throughout the Carina Nebula. The cluster is 6-to-13 light-years throughout and has a few of the hottest and largest stars discovered within the Milky Method.
What is it?
The JWST helped uncover for the primary time the complete inhabitants of brown dwarfs in this massive young star cluster, including objects as small as around 10 times the mass of Jupiter.
Brown dwarfs are grouped under the “dwarf” umbrella because they are star-like objects that form from collapsing gas clouds, yet never become big enough to sustain long-term hydrogen fusion like true stars.
Where is it?
The Carina Nebula is located in the Carina constellation, around 20,000 light-years away from Earth.
Why is it amazing?
Finding brown dwarfs in this harsh and brilliant environment is important because it helps astronomers answer a key question: How efficiently are low-mass objects, like brown dwarfs, being made when there’s intense radiation in the area? A complete census of the stars in the image lets scientists compare the Westerlund 2 cluster to quieter star-forming areas and take a look at whether or not excessive circumstances change the “combine” of the objects which might be fashioned.
