X-ray images expose chaotic inner layers of supernova Cassiopeia A

Chandra X‑ray images of Cassiopeia A reveal a “shell merger” where a silicon‑rich layer collided with a neon‑rich layer hours before collapse. The star exploded about 11,300 years ago. getnews.me/x-ray-images-expose-chao... #cassiopeiaa #supernova

Chandra Reveals Turbulent Mixing Inside Cassiopeia A Supernova

Chandra X‑ray images show a ‘shell merger’ in Cassiopeia A, mixing silicon‑rich and neon‑rich layers just hours before the star exploded. The remnant lies about 11,000 light‑years from Earth. getnews.me/chandra-reveals-turbulen... #cassiopeiaa #supernova

Cassiopeia A Cassiopeia A (Cas A) is a supernova remnant (SNR) in the constellation Cassiopeia and the brightest extrasolar radio source in the sky at frequencies above 1 GHz.

#CassiopeiaA is a #Supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia.

It is the remnant of a massive star that exploded approximately 340 years ago as seen from Earth.

A stunning false-color image of Cassiopeia A, a supernova remnant 11,000 light-years away. The image combines X-ray (Chandra) and optical (Hubble) data, showcasing vibrant filaments of silicon (red), sulfur (yellow), calcium (green), and iron (purple), with the outer blast wave in blue. A neutron star, the collapsed core of the exploded star, is visible near the center. This image depicts the final, spectacular phase of a massive star's life cycle and the recycling of elements within our galaxy.

James Webb Space Telescope's NIRCam image of Cassiopeia A, a supernova remnant approximately 20 light-years across. The image showcases the hot filaments and knots of the expanding blast wave, along with light echoes from the initial explosion. The vibrant colors depict the enriched material ejected from a massive star's death, showcasing the beauty and power of stellar evolution in our Milky Way galaxy. Light from this supernova reached Earth approximately 350 years ago, traveling 11,000 years to reach us.
