Monocerotis (V838 Mon) is a supergiant star, one of the most brilliant of our Galaxy, it is located in the constellation Monoceros about 20,000 light years.
But the most surprising is that V838 Monocerotis did not expel its outer layers. Instead, it has grown enormously in size. Its surface temperature is dropped to ridiculously low temperatures. This behavior is very unusual and completely different from an ordinary nova explosion. However, the explosion may represent a transitional phase ever observed in the evolution of a star. V838 Monocerotis has some similarities with the stars very unstable during aging called 'eruptive variables', some of which increase brightness suddenly and unexpectedly. The accuracy of the image taken by Hubble shows complexity of the internal cloud, which evokes a chaotic structure with an envelope in highly loaded to matter, while the interior is almost empty. It is possible that star Monocerotis V838 is a dying aster going through several cycles of contractions and explosions. The star is located in Monoceros constellation, near north celestial pole.
