SECCHI Uncovers What? Near Mercury

  1. Dec 11, 2011 #1
    Interesting video. Nice stop-action at 2:12 min.

    I don't believe in aliens, so what might this actually be?

    Mercury's day side is hot enough (upwards of 800 deg F) to create some serious off-gassing. It's surface gravity is significant at 0.38 g, but it has no atmosphere to speak of.

    Could this illuminated "object" merely be the front edge of a gas cloud to the sunward side of the planet? If not, what else might it be?
