OVER the previous decade, spacecraft have beamed again studies from some actually awe-inspiring locations inside our photo voltaic system. Rovers have revealed huge river channels carved by historical floods on Mars. Probes have zipped by way of the turbulent geysers erupting from Saturn’s icy moon Enceladus.

Let’s think about that we may roam throughout the Milky Way on a sightseeing journey like no different. The place would I take you? Effectively, supermassive black holes, unusual, pulsating stars and unique Earth-like worlds are on the itinerary for starters.
