The pyramids have exerted a powerful spell on the western world. Where once they were thought to be giant granaries, astronomy has revealed their true purpose.

Since radio telescopes were developed, significant discoveries have been made. Here we list 5 amazing radio telescope discoveries.
Ever since Tycho Brahe died suddenly more than 400 years ago, there has been a mystery about whether the Dane whose observations laid the groundwork for modern astronomy fell victim to natural causes or was murdered.
