It all started in 2002 when the Hubble telescope trained on an area of the sky where the star V838 Monocerotis was located.
Over a 4 year period, Hubble continued to take still shots of the same area. When put together they make a remarkable video of an exploding star that only time-lapse photography can provide.
The original video is at www.spacetelescope.org/videos/heic0617a/ if you want to watch it there, but blogger “Our Universe Visualized” put it on YouTube and provided some commentary that is well worth reading.
This is not a new video, but it is still fascinating to watch …
