A very red star emerged a few months after the outburst. It had erupted several years earlier, which was undetected, but may have been the result of two stars merging within a three-star system. V838 Monocerotis ( Nova Monocerotis 2002) is een spectroscopisch dubbelstersysteem in het sterrenbeeld Monoceros op ongeveer 19.000 lichtjaar (6 kpc) van de zon.De voorheen onopgemerkte ster werd begin 2002 waargenomen tijdens een grote uitbarsting en was mogelijk een van de grootste bekende sterren gedurende een korte periode na de uitbarsting. V838 Monocerotis is not part of the Monoceros constellation outline but is within the borders of the constellation. The illumination of interstellar dust comes from the red supergiant star at the middle of the image, which gave off a flashbulb-like pulse of light two years ago. The absolute luminosity of V838 Mon during its outburst, based on our distance measurement, was very similar to that of M31 RV, an object in the bulge of M31 that was also a cool supergiant throughout its eruption in 1988. Two new images provide the most astonishing views of V838 to date. V838 Monocerotis is a red variable star also known as Nova Monocerotis 2002, located in the constellation Monoceros.

(2002) suggested classifying it as a new class of variable, while Retter & Marom (2004) suggested that the outburst was the result of expansion to a red giant, during which three massive planets in close orbits were swallowed. It continues to illuminate a spectacular series of light echoes, as the outburst light is scattered from nearby circumstellar dust. Unlike a classical nova, which quickly evolves to high temperatures, V838 Mon remained an extremely cool, luminous supergiant throughout its eruption. It became famous in 2002, when it had a major outburst and briefly became one of the largest stars known and one of the most luminous stars in the Milky Way, with a luminosity about 600,000 times that of the Sun.
