Astronomers are getting a fresh look at the core of our home galaxy, the Milky Way, in new detail with NASA's James Webb Space Telescope.
Webb captured the image below of the star-forming region of the Milky Way known as Sagittarius C, which is about 300 light-years from our galaxy's supermassive black hole, Sagittarius A*.
According to NASA, the image was taken using Webb's Near-Infrared Camera and includes an estimated 500,000 stars. Among the thousands of stars are newly formed stars known as protostars. Within the new image is a protostar cluster, including a newly discovered massive protostar about 30 times the mass of our solar system's Sun.

"There’s never been any infrared data on this region with the level of resolution and sensitivity we get with Webb, so we are seeing lots of features here for the first time," said observation team principal investigator Samuel Crowe, with the University of Virginia. "Webb reveals an incredible amount of detail, allowing us to study star formation in this sort of environment in a way that wasn’t possible previously."
Infrared light, unlike visible light, can pass through gas and dust, capturing sharp details of cosmic features.
"The galactic center is a crowded, tumultuous place. There are turbulent, magnetized gas clouds that are forming stars, which then impact the surrounding gas with their outflowing winds, jets, and radiation," said Rubén Fedriani, co-investigator of the project with the Instituto Astrofísica de Andalucía in Spain.
According to NASA, studying the Sagittarius C region with Webb will help astronomers understand how stars form and how different cosmic environments play a role in star formation.
