This is an image of the newly-discovered Red Square nebula, detailed in last week's issue of the journal Science. A nebula is an interstellar cloud of gas, plasma, and dust. At the heart of the Red Square nebula is a dying star identified as MWC 922. This infrared image was taken at Palomar and Keck Observatories (Credit: Peter Tuthill). Apparently, the Red Square is one of the most symmetrical objects ever spotted by astronomers. The Red Square’s extreme symmetry suggests the star’s surroundings are extremely still and not buffeted by external stellar winds or other turbulence... The new findings suggest the system’s perfect form results from an even outflow of gas.
