Scientists with the Max Planck Institute for Solar System Research and the Astronomical Institute at Ludwig Maxmillian University say that their observations suggest that the comet’s nucleus has broken apart. What evidence? They said the comet ISON, which is currently viewable in the eastern predawn sky, has wings. They said the coma wings suggests the presence of two or more sub-nuclei with individual expanding atmospheres and may indicate the nucleus splitting in the coma. And what does that mean? Less of a chance of survival for the comet’s nearing encounter with the sun.
