Webb peers into the Extreme Outer Galaxy

Within the Milky Way’s outskirts is a firecracker show of star formation.

Astronomers have examined the Extreme Outer Galaxy, also known as the outskirts of our Milky Way galaxy, using the NASA/ESA/CSA James Webb Space Telescope. Located over 58,000 light-years from the galactic center, this region is a firecracker show of star formation.

Thanks to Webb’s near- and mid-infrared imaging capabilities, scientists imaged selected regions within two molecular clouds known as Digel Clouds 1 and 2. The instruments’ high sensitivity and sharp resolution allowed scientists to resolve these areas, which are the birthplace of star clusters undergoing bursts of star formation, in unprecedented detail.
