How do astronomers study the Universe? Our planet is covered with observatories of all kinds, big and small, amateur and professional, old and new. Many more still are orbiting over our heads daily. Yet prior to 1929 (less than 90 years ago), we didn’t even know there was a Universe beyond our own Milky Way, let alone astronomical objects that gave off more than just visible light. Go on a tour of the multi-wavelength universe and see highlights of some exciting new findings.
