Answer to Question 1

The violence of active galaxies is so great it can influence entire clusters of galaxies. The Perseus galaxy cluster contains thousands of galaxies and is one of the largest objects in the Universe. One of its galaxies, NGC 1275, is among the largest galaxies known. It is pumping out jets of high-energy particles, heating the gas in the galaxy cluster, and inflating low-density bubbles that distort the huge gas cloud. The hot gas observed in galaxy clusters is heated to multimillion-degree temperatures as galaxy after galaxy goes through eruptive stages that can last for hundreds of millions of years. NGC 1275 is erupting now, and it is so powerful and has heated the surrounding gas to such high temperatures that the gas can no longer fall in and the galaxy has probably limited its own growth.

Answer to Question 2

B
