Face it, the vast darkness of space is a little eerie. It’s no wonder we usually prefer to focus on the bright spots.
But it’s in the void that we might find our best explanations of the cosmos.
In 1923, Edwin Hubble showed that the universe was far larger than expected by discovering that what we thought were swirls
of gas on the edge of our own galaxy were actually galaxies in their own right: lonely “island universes” we could spot across
an empty sea of black. That led to a comforting thought – we now know that even the darkest patch of sky, when seen through
the telescope named after Hubble, is dotted with clumps of luminous stuff like our Milky Way.
