APOD 3.8

This picture shows a pair of binary galaxies that, in a few billion years, will merge and become one galaxy. The two galaxies have caused effects on each other, due to their gravity. One has caused richer spirals in the other and the other one has violent star forming regions and colliding gas clouds that emit x-rays.

This picture shows newly resolved images of the Milky Way Galaxy. The pictures are of cold dust in the galaxy and are in infrared. The photo was taken by the European Space Agency's Planck Satellite. This gas is within 500 light years of the earth and is between 10 kelvin and 40 kelvin degrees.

APOD 3.6

This picture is of the constellation Auriga, the charioteer. It shows M36, M37, and M38 as well as shows three emission nebula, a concept that has been recently discussed in class. It shows the star forming regions of IC 405, IC 410, and IC 417. The picture also has an overlay that appears when one scrolls the mouse on the picture showing exactly where the objects that are talked about are.

This picture is of a binary black hole system in the Abell 400 galaxy cluster. The black holes are 25,000 light years apart and they are about 300,000 light years from the earth. This was very interesting to me because we have just studied black holes and talked about how they form.
