Title: Radio Astronomy: An Important Tool

Author: Nitza Santiago

Performer: Nitza Santiago

Abstract: Radio astronomy is an indispensable tool used by scientists to study the Universe. Throughout the years astronomers have used it to learn more about different sources of radio emission such as stars and galaxies. It was through radio observations that scientists discovered the first planet outside the solar system, circling a distant pulsar. Additionally, scientists first discovered the cosmic microwave background using radio observations, which provided convincing evidence for the fiery birth of the Universe in the Big Bang. In this podcast, I'll talk about what makes radio astronomy so important.
