Watch this impressive time-lapse footage of the star V838 Monocerotis explode 20,000 years ago.

A composition of images captured by Hubble Space telescope, from 2002 to 2006.

For reasons unknown, star V838 Monocerotis that lies about 20,000 light years away, suddenly became one of the brightest stars in the entire Milky Way. Then, just a few months later, it faded.
