The remnant of a Supernova explosion3D ModelNoAI
Massive stars end their lives with catastrophic explosions known as Supernovae (SN). The outcomes of these explosions are extended nebulae called Supernova Remnants (SNR). The artist view represents a SNR of a massive star that went into a SN a few hundreds years before. The SNR is bounded by the shock caused by the SN and consists of stellar debris ejected from the explosion with velocities of thousands of km/s and interstellar material swept up by the shock. A neutron star (the leftover of the progenitor star) is nearly located at the center of the remnant. SNRs encode precious information about the physical processes that govern the SN engine and the latests stages of stellar evolution. For this reason their study is critical for unraveling many mysteries of SN explosions and stellar evolution. Powerful tools for these studies are MHD models as those that describe the SNR Cassiopeia A and SN 1987A.
