NASA’s Webb Uncovers Star Formation in Cluster’s Dusty Ribbons.
NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery.
Now, it is less mysterious with new findings from NASA’s James Webb Space Telescope.
NCG 346 is located in the Small Magellanic Cloud (SMC), a dwarf galaxy close to our Milky Way.
The SMC contains lower concentrations of elements heavier than hydrogen or helium, which astronomers call metals, compared to the Milky Way.
Since dust grains in space are composed mostly of metals, scientists expected there would be low amounts of dust, and that it would be hard to detect.
New data from Webb reveals the opposite.

Astronomers probed this region because the conditions and amount of metals within the SMC resemble those seen in galaxies billions of years ago, during an era in the universe known as “cosmic noon,” when star formation was at its peak.

Wouldn't have one NGC 346 Lake the small Magellanic Cloud does it would have Thousands of star-forming regions like This one said Margaret meixner an Astronomer at the University's space Research Association and principal Investigator of the research team but Even if NGC 346 is now the one and only Massive cluster furiously forming stars In its Galaxy it offers us a great Opportunity to probe conditions that Were in place at Cosmic noon by Observing protostars still in the Process of forming researchers can learn If the star formation process in the SMC Is different from what we observe in our Own Milky Way previous infrared studies Of NGC 346 have focused on protostars Heavier than about five to eight times The mass of our sun with web we can Probe down to lighter weight protostars As small as one tenth of our sun to see If their formation process is affected By the lower metal content set Olivia Jones of the United Kingdom astronomy Technology Center Royal Observatory Edinburgh a co-investigator on the Program as stars form they gather gas And dust which can look like ribbons and Web imagery from the surrounding Molecular cloud the material collects Into an accretion disk that feeds the Central protostar astronomers have Detected gas around protostars with nngc
