There’s a Birth Control for Stars

The video explores the fascinating world of quasars, which are extremely bright and distant objects powered by supermassive black holes at the centers of galaxies. Discovered in the 1950s, quasars are known for their intense brightness, often outshining entire galaxies. They are a type of Active Galactic Nucleus (AGN) and can produce powerful outflows that influence star formation in their host galaxies. Recent research using the Hubble Space Telescope has provided insights into the speed and reach of these outflows, suggesting that they play a significant role in regulating the formation of new stars. However, the debate on their full impact continues, with new telescopes like the James Webb Space Telescope expected to provide further clarity.

How do astronomers measure the speed and extent of outflows from quasars?

What findings were reported regarding the acceleration of outflows in quasars?
