Quasar Tsunamis Rip Across Galaxies - Science@NASA The quasar winds snowplow across the galaxy's disk Material that otherwise would have formed new stars is violently swept from the galaxy, causing star birth to cease Radiation pushes the gas and dust to far greater distances than scientists previously thought, creating a galaxy-wide event
23. 2 Evolution of Massive Stars: An Explosive Finish - OpenStax 23 2 Evolution of Massive Stars: An Explosive Finish Learning Objectives By the end of this section, you will be able to: Describe the interior of a massive star before a supernova Explain the steps of a core collapse and explosion List the hazards associated with nearby supernovae Thanks to mass loss, then, stars with starting masses of at least 8 MSun (and perhaps even more) probably end
Supernovae Information and Facts - National Geographic A supernova can light the sky up for weeks, and the massive transfer of matter and energy leaves behind a very different star Typically only a tiny core of neutrons, a spinning neutron star, is
Quasar - Wikipedia Quasars show evidence of elements heavier than helium, indicating that galaxies underwent a massive phase of star formation, creating population III stars between the time of the Big Bang and the first observed quasars
Extreme quasars illuminate the fast lives of the first black holes California Institute of Technology astronomer Maarten Schmidt found the first quasar in 1963, when he realized that a blue “star” seemingly in our galaxy was actually far beyond it The clue came from the blue object’s redshift
