APOD 3.5

This picture, "WISE Infrared Andromeda" caught my eye immediately for several reasons. The picture is very vibrant and has a multitude of colors and depths that can be seen when viewed closely. Not only this, but the content of the picture interested me as well. The picture deals with the Andromeda Galaxy, in the Andromeda constellation, which we have studied and thus is very relevant to my interests. It is very cool to see detailed and scientific pictures about material that we have studied in this class. Furthermore we have recently been learning about infrared light, the way it looks in pictures when observed, and how it emphasizes certain aspects of astronomical objects when observed. The article itself was very educational, and I learned two things which were very interesting to me. The first was that the Andromeda Galaxy is the largest one in its region, and thus it is very important. And the second thing that I learned is that the particular infrared detector used to take this picture, is so powerful that it needs to be cooled by frozen hydrogen.
