I like watching pictures and movies of supernova remnants while thinking what is going on. Let's enjoy it with me!

Cassiopeia A (~350 yr old, core-collapse SNR)

Chandra movie (Sato et al. 2018, 853, 1, 46, ApJ)

What does make the "inward moving" features?

Radio movie 1978→1994 (see Rudnick et al., 1996)

Tycho's SNR, SN 1572 (~440 yr old, Type Ia SNR)

Three-dimensional view of Tycho's SNR using the Doppler effect. 

Blue structures are on front side, and red ones are on back side.

Iron vs intermediate mass elements (IME, Si+S+Ar+Ca)

How many can you find differences?
