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?
Chandra movie 2000-2018 (green=Si, red=Fe, blue=non-thermal)
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?

Kepler's SNR, SN 1604 (~410 yr old, Type Ia SNR)
Chandra movie (Sato & Hughes 2017, 845, 167, ApJ)
Fe (red), Si (green), Non-thermal (blue).

No surviving donor star!?
