Q. The term “Saggitarus *A” is often seen in news is related to which of the following?
The center of our Milky Way Galaxy is anchored by a black hole that is nearly 5 million times the mass of our Sun.
- Surrounding it is a chaotic city of stars, gas, and dust that we call Sagittarius A.
- We stacked false-color X-ray, infrared, and radio images into this single picture to show you the different structures hidden inside the core of our Galaxy.
- X-rays (purple) radiate from the super-hot gas trapped in the black hole’s grasp.
- The surrounding dust is heated by friction as it chaotically orbits around the black hole and then glows in infrared light (gold).
- And the enormous pools and three-armed rivers of gas shine in radio light (oranges and reds) to trace the complexity of magnetic fields in this violent neighborhood.
