Exotic objects in the sky

Learn all about black holes, pulsars and the weirdest star in the universe in this free guide from Astronomy. Uncover the history behind Einstein's theory of relativity, expanded to include gravitational forces along with electricity and magnetism, as well as the history of black holes.

This free download also explains pulsars, and how these rotating neutron stars are being used by scientists today to search for planets beyond Earth's solar system.

And finally: What is the weirdest star in the universe? TSOs, or Thorne-Zytkow objects, which are formed when a red supergiant swallows a neutron star. How are astronomers tracking these supergiant stars? And what can they tell us about stellar evolution?
