James Webb Space Telescope Captures Image of Exploded Star Cassiopeia A with NIRCam

James Webb Space Telescope Cassiopeia A NIRCam
Hubble may have provided a detailed look at exploded star Cassiopeia A, but the James Webb Space Telescope takes things to a whole new level. Thanks to its NIRCam (Near-Infrared Camera), astronomers are able to study the supernova remnant at a resolution previously unachievable at these wavelengths.

What stands out immediately are the bright orange and light pink clumps that make up the inner shell of the supernova remnant. NIRCam is capable of detecting the tiniest knots of gas, which are comprised of sulfur, oxygen, argon, and neon from the star itself. Within this gas is a mixture of dust and molecules that will eventually become components of new stars as well as planetary systems.

With NIRCam’s resolution, we can now see how the dying star absolutely shattered when it exploded, leaving filaments akin to tiny shards of glass behind. It’s really unbelievable after all these years studying Cas A to now resolve those details, which are providing us with transformational insight into how this star exploded,” said Danny Milisavljevic of Purdue University.

NASA’s James Webb Space Telescope shows a portion of the dense center of the Milky Way galaxy like never before. This includes the star-forming region, named Sagittarius C (Sgr C), located approximately 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*.

In addition to the estimated 500,000 stars in the image, Webb’s NIRCam (Near-Infrared Camera) also captured a cluster of protostars, resulting in outflows that glow like a bonfire in the midst of an infrared-dark cloud. Why is this significant? Well, there’s never been any infrared data on this region with the level of resolution and sensitivity that Webb can provide, so astronomers are seeing lots of features here for the first time.

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. Webb has provided us with a ton of data on this extreme environment, and we are just starting to dig into it,” said Rubén Fedriani, a co-investigator of the project at the Instituto Astrofísica de Andalucía in Spain.
