Dark Matter in Astrophysics
Transcript of Dark Matter in Astrophysics
in Astrophysics Dark matter is a hypothesized form of matter that doesn't interact with light, so it is invisible. Astronomers deduced its presence by noting its gravitational pull on stars in galaxies makes up about 25 percent of all matter in the universe. WHAT IS DARK MATTER The Bullet cluster is actually two galaxy clusters which have collided against each other. WHAT IS THE BULLET CLUSTER As they passed through each other, the gas in each cluster interacted, producing a drag force similar to air resistance, and slowed down. This is how normal matter behaves. However... dark matter only interacts with gravity, and so the dark matter in the clusters is able to move ahead of the gas, producing the shape of the Bullet seen today. Bullet Cluster Invisible Dark Matter May Create Habitable Zones for Life it contains about 1,000 galaxies and trillions of stars. The NASA Hubble Space Telescope shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689 A new study suggests that mysterious, invisible dark matter could warm millions of starless planets in regions such as Abell 1689 and make them habitable?!?!?!?!?!
