NASA | Hubble Time-lapse of “Light Echo” #nasa#spaceexploration #artemis #spacemissions #iss #rocket

This isn’t an explosion, but an echo! In this timelapse of Hubble images, a burst of light from the bizarre star V838 Monocerotis is spreading into space and reflecting off of surrounding shells of dust. V838 Monocerotis is located about 20,000 light-years away.
