From 550 Light Years Away… The Ghost of Cassiopeia, Captured by me. #reels #reelsfb #astrophotography #universe #space #Astronomy | AstroLee

Zoom into Cassiopeia A | James Webb Space Telescope FriendsofNASA.org: This video takes the viewer on a journey to Cassiopeia A (Cas A), a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. It spans approximately 10 light-years. This new image uses data from Webb’s Mid-InfraRed Instrument (MIRI) to reveal Cas A in a new light. On the remnant’s exterior, particularly at the top and left, lie curtains of material appearing orange and red that are due to

😨 The supernova explosion Cassiopeia A ⭐️ is expanding at an average rate of 4,000 to 6,000 kilometers per second!! This translates to roughly 13.4 million mph. The expansion is primarily due to the shock wave of the supernova explosion pushing through the surrounding gas and dust. Space is beautiful and violent.
