Can you imagine a trip from our Solar System into the Virgo Supercluster 60 million light years away? Then whizzing home via a shortcut through a black hole?

In the 16th century everyone knew that Earth was the center of the cosmos. But this made it impossible to predict the motions of heavenly bodies, even if they moved in elaborate circles within circles. Copernicus turned the idea on its head and put the Sun at the center.

Another seethes with volcanic activity and has mountains taller than Everest. And which one has an ocean that could harbor life? Jupiter's Galilean Moons

Yet just visible to the unaided eye is a vast stellar nursery where the next generation of stars is forming. Orion the Hunter
