I never thought that I was going to see something like this: A video of a star bursting in space, lighting the intergalactic dust around it at the speed of light. One thing to be noted here is that. this is not a computer recreation. It's a genuine time-lapse video taken over four years by the Hubble and researchers don't know its cause yet. “The NASA/ESA Hubble Space Telescope has been seeing the V838 Mon light echo since 2002. Each new reflection of the light echo discloses a new and distinctive "thin-section" through the interstellar dust nearby the star. This video transforms images of the light echo from the Hubble captured at numerous times between 2002 and 2006. The several spirals and eddies in the interstellar dust are mostly visible. Perhaps they have been formed by the effects of magnetic fields in the space between the stars.”
V838 Monocerotis, lies in the constellation Monoceros, 20,000 light years away from Earth, suffered a rapid outburst in 2002, grasping astronomers by amazement. The variable red star got so big that it developed one of the biggest stars ever detected, generating 600,000 times more light that the Sun. Researchers believed it was a nova, but then they recognized they were wrong. The source of this remarkable outbursts, which brightened the interstellar dust around it at the speed of light, is still unidentified.
