21 cm Detector: Day 4- May 22

Today we made some finishing touches on our low noise amplifier assembly. Then we spent the day learning some background information on radio astronomy and radio waves. Radio astronomers study regions in space that cannot be seen in visible light. It is the study of objects in space that give off radio waves. We are able to find the location, density, and motion of hydrogen gas in the universe because of radio waves. We hope to start work on the signal amplifier next to connect it to the low noise amplifier so that we can test it.
