@stargazerdaily.bsky.socialJets pierce galaxies. Relativistic jets are plasma streams near light speed, extending, heating gas.
Seen in M87 and quasars.

@theastronomer1.bsky.socialJets heat gas, changing star formation. Powered by accretion disks, they race near light speed.
M87 and quasars illustrate this.
