Episode description and notes
Stretching about 100,000 light-years in diameter, it is a part of a larger group of galaxies known as the Local Group. This majestic galaxy, seen from Earth as a milky band of light arching across the night sky, contains a complex structure of spiral arms wrapped around a dense central bulge, which is believed to harbor a supermassive black hole known as Sagittarius A*.
