OVER the previous decade, spacecraft have beamed again experiences from some really awe-inspiring locations inside our photo voltaic system. Rovers have revealed huge river channels carved by historic floods on Mars. Probes have zipped by means of the turbulent geysers erupting from Saturn’s icy moon Enceladus. We’ve even flown previous the frigid mountains of Pluto. However what if we may lengthen our horizons additional – a lot additional?
Let’s think about that we may roam throughout the Milky Manner 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. Apart from the sheer spectacles we’ll witness, we’ll uncover how visiting these area oddities would possibly provide clues to some huge mysteries – from how the primary stars shaped to what’s producing bizarre radio indicators from outer area and whether or not there’s life past Earth. Right here, then, is my information for the discerning galactic vacationer.

To start our journey, we’ll leap right into a river of stars that loops proper previous our entrance door and throughout your complete Milky Manner. To really recognize the S1 stream, now we have to recalibrate our sense of scale, as a result of its size and breadth are counted in 1000’s of sunshine years. Our photo voltaic system, sat in the course of the stream, is akin to a grain of sand within the Amazon river.
To search out the supply of the S1 stream, we have to flip again the clock almost 9 billion years to our galaxy’s turbulent youth. Seen from the surface, the …
