Did you know that we can “listen” to the universe? Let's explore the wonders of radio astronomy! Radio astronomy is a fascinating field that studies celestial objects emitting radio waves. It all started in 1933 when Karl Jansky discovered radio waves from the Milky Way. Using huge radio telescopes, we can peer into the clouds and dust and reveal the secrets of the cosmos! Unlike optical telescopes, radio telescopes can see through clouds, dust and even the vastness of space! Unlike radar astronomy, which is active, radio astronomy is passive and simply receives signals. This incredible science helps us understand pulsars, quasars, black holes and the cosmic microwave background – the afterglow of the Big Bang. By capturing radio waves, we decode the mysteries of the universe!
