This is still just an Early Release Observation, and it's still pretty amazing. JWST Sees Furious Star Formation in a Stellar Nursery
We all marvelled at that image back in July, but scientists have dug into it to learn more about the region and the star-forming activity happening there. The Monthly Notices of the Royal Astronomical Society published a paper presenting the results of their work. It’s titled “” The lead author is astronomer Megan Reiter of Rice University in Houston, Texas.
The JWST’s powerful infrared capabilities fuelled this study. It can focus on molecular hydrogen, the main ingredient in stars. It’s an excellent tracer for star-forming activity because as young stars grow, they take in the hydrogen and eject some of it in jets and polar outflows. It’s calledThis image shows some of the new features that the James Webb Space Telescope found in the Carina Nebula’s Cosmic Cliffs. Image Credit: NASA, ESA, CSA, and STScI. Image processing: J.

“It opens the door for what’s going to be possible in terms of looking at these populations of newborn stars in fairly typical environments of the universe that have been invisible up until the James Webb Space Telescope,” added Reiter. “Now we know where to look next to explore what variables are important for the formation of Sun-like stars.”
This image is a zoomed-in region of the full-size image. It shows the star cluster NGC 3324 and the two bright young stars responsible for ionizing the region of gas surrounding them. Image Credit: NASA/ESA/CSA/JWST ReiterUnderstanding how young stars form is one of the primary quests in astrophysics today. The collective light from the first stars helped drive the reionization of the early Universe. Before the, a dense fog of primordial gas obscured the Universe.
These are Early Release Images and are just the beginning of the JWST and its study of stellar formation. “Future observations will allow quantitative analysis of the excitation, mass-loss rates, and velocities of these new flows,” the authors write. “As a relatively modest region of massive star formation, NGC 3324 offers a preview of what star formation studies withFuture observations will be more thorough and detailed.
