Light Echo from Star V838 Monocerotis

This sequence of pictures from the NASA Hubble Space Telescope's Advanced Camera for Surveys dramatically demonstrates the reverberation of light through space caused by an unusual stellar outburst in January 2002. A burst of light from the bizarre star is spreading into space and reflecting off of surrounding shells of dust to reveal a spectacular, multicolored bull's eye.

This sequence of pictures from May to December 2002 shows apparent changes in the appearance of the circumstellar dust as different parts are illuminated sequentially. This effect is called a "light echo." From the first to last image the apparent diameter of the nebula appears to balloon from 4 to 7 light-years. This gives the illusion that the dust is expanding into space faster than the speed of light. In reality the dust shells are not expanding at all, but it is simply the light from the stellar flash that is sweeping out into the nebula. The different colors in the nebula reflect changes in the color of the star during its outburst.

The red star at the center of the eyeball-like feature is an unusual erupting supergiant called V838 Monocerotis, located about 20,000 light-years away in the winter constellation Monoceros (the Unicorn). During its outburst the star brightened to more than 600,000 times our Sun's luminosity.

The circular feature has now expanded to slightly larger than the angular size of Jupiter on the sky. For several more years it will continue expanding as reflected light arrives from more distant portions of the nebula. Eventually, when light from the back side of the nebula begins to arrive, the light echo will give the illusion of contracting, and finally it will disappear by the end of this decade. The black gaps around the red star are regions of space where there are holes in dust. This shows the nebula has a Swiss-cheese structure.

The above article must be wrong in its interpretation of the data.  Look at the animation of the images I provided.  This is clearly a single layer explosion of debris leaving the red giant.  The idea of a "light echo" is nonsense.  If there was such a thing as a light echo, all the dust in the galaxy would be visible due to the myriad sources of light.  Also, the light intensity of the explosion would be inversely proportional to the distance from its source.  The light intensity from this debris is constant.

Whatever the explanation is, this series of images likely provides evidence that key assumptions about astronomical physics are wrong.  Obviously the distances being traveled by the cloud are far shorter than the scientists have calculated.
