The universe is amazing, it is estimated that there are about 50 billion galaxies out there. And who knows what life exists, maybe one day future generations will get to zip from galaxy to galaxy, wouldn’t that be amazing? Here’s Nasa’s video of the unusual variable star V838 Monocerotis (V838 Mon). The star underwent an outburst early in 2002 when it temporarily increased in brightness to become 600,000 times more luminous than our Sun.
As light from the eruption propagates outward into the dust, it is scattered by the dust and travels to the Earth. This video morphs images of the light echo from the Hubble taken at multiple times between 2002 and 2006.
