In time, any given galaxy begins to run out of recyclable gas. Without gas, it can’t form new stars; the old stars live out their lives and die, and eventually the galaxy dies too. … The galaxies breathe gas in and out, and their stars burn until their gas is gone. Within a galaxy, relatively dense gases fuel star birth.

Where is our galaxy in the universe?

The Milky Way is a spiral galaxy comprised of a bar-shaped core region surrounded by a flat disk of gas, dust and stars about 120,000 light-years wide. Our solar system is located about 27,000 light-years from the galactic center within one of the disk’s four spiral arms.

What is the biggest galaxy?

IC 1101The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive. It is about 5.5 million light-years across.

What is beyond the galaxy?

Scientists have long been unable to find exoplanets—planets outside the solar system—beyond the confines of the Milky Way. After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it’s incredibly difficult to see beyond that.

What galaxy do we live in?

Is our galaxy moving?

The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).
