Supernova remnant Cassiopeia A, X-ray
Supernova remnant Cassiopeia A, X-ray image. Cassiopeia A (Cas A) is a remnant of a supernova star that exploded around 320 years ago, the youngest in the Milky Way galaxy. The shells of gas are constantly expanding, and within them electrons are accelerated to extremely high speeds (blue wispy arcs). The red and green areas are material from the star that has been heated to millions of degrees, causing it to emit radiation. Cas A is about 10 light years in diameter and is found around 10, 000 light years from Earth in the constellation Cassiopeia. Image taken by NASAs Chandra X-ray observatory in 2004

EDITORS COMMENTS
This print showcases the stunning Supernova remnant Cassiopeia A in X-ray, offering a glimpse into the explosive aftermath of a star's demise. Approximately 320 years ago, this supernova event occurred, making it the youngest known within our Milky Way galaxy. The image reveals the expanding shells of gas that surround Cas A, with wispy blue arcs representing electrons accelerated to incredible speeds within them. The vibrant red and green areas depict material from the destroyed star that has been heated to millions of degrees, resulting in the emission of powerful radiation. Spanning an impressive diameter of about 10 light years, Cas A resides roughly 10,000 light years away from Earth in the constellation Cassiopeia. Captured by NASA's Chandra X-ray observatory in 2004, this photograph provides valuable insights into astrophysics and cosmology. It serves as a testament to both the destructive power and awe-inspiring beauty found within our universe. This false-colored image allows scientists to study various physical phenomena associated with stellar death and acceleration processes. Presented by Science Photo Library, this remarkable print invites viewers on a visual journey through space and time while highlighting humanity's ongoing quest for knowledge about our celestial surroundings.
