Hubble’s image of V838 Monocerotis reveals changing light echoes, illuminating hidden dust patterns since the star’s sudden brightening in early 2002. Hubble captures a three-light-year gas ...

To date, most of the light echoes we've detected tend to be from very bright events or very thick dust close to the light source, as we see in the star V838 Monocerotis. Thinner dust, farther from the ...

Light echoes at visible wavelengths (such as those seen around the star V838 Monocerotis) are due to light reflecting off of interstellar material. In contrast, light echoes at infrared ...

V838 Monocerotis is a cataclysmic binary star in the constellation Monoceros about 19,000 light years from the Sun. V838 Monocerotis is a cataclysmic binary star in the constellation Monoceros about ...

Light bouncing off of interstellar material is the cause of light echoes at visible wavelengths, like those observed orbiting the star V838 Monocerotis. On the other hand, when the dust is warmed by ...
