Spiral Galaxie Collisions Occur More Often
News story originally written on May 11, 1999
Scientists are finding strong evidence thatspiral galaxies collide more
often than once thought. It was once believed that one third of all the
spiral galaxies have had a collision. However, a new camera developed at
Ohio State University sheds new light on the subject.
The camera takes pictures in infrared light like a regular camera takes pictures in visible light. This new technology allows scientists to look through dust in the center of the galaxies.
In the center of spiral galaxies lie bar-shaped bands or stars called barred spirals. It is believed that these barred spirals are caused by
collisions. Using the infrared camera, scientists have discovered many
more barred spirals in galaxies.
