Another Version of the Pillars of Creation from Webb - by spacewriter
This star-birth region has a long history of observations. It’s certainly visible to astronomers using backyard-type telescopes. However, it takes Hubble Space Telescope and now JWST to dig into the rich detail of this massive cloud. HST first looked at it in 1995, using the Wide Field and Planetary Camera 2. It returned 32 images, which were combined into a mosaic. The pillars are part of the Eagle Nebula.
The protostars as seen by NIRCam are the ones with multiple diffraction spikes. They’re still accreting mass, and when they get enough, they’ll collapse under their own gravity and slowly heat up. When they’re hot and massive enough, fusion will ignite in their cores. That’s when they become stars. The young stars in these pillars are probably only a few hundred thousand years old and won’t be finished forming for millions of years.
