    Comet destroyed in collision with star

    Amazing story, apparently they observed a comet colliding with a 100,000 year old star, which is 3200 lightyears away from us:

    Whoa.
    The comet - a 100km-wide body made of rock and ice - was ripped apart and destroyed by the heat of the star.
    Hmmmm... how do they know how big it was?

    From RedNova News

    "We know how hot the star is and how close to the star the neutral sodium atoms can survive. From that, and from the motion of the cometlike body during infall onto the star, we calculated how large the body would have to be to get this close to the star -- one-tenth of the distance between the Sun and the Earth -- before vaporizing."

    This encourages me. If we can detect comets vaporizing 3,200 ly away, we shouldn't have too much trouble detecting planets.

    Sure, we just have to figure out how to vaporize them first. :-?

    you know, seeing that picture in the first article makes me want to be one of those people who do the artists depictions of astronomical events for some reason.
