NEAT Comet Crossing: Internet Telescopes

An anonymous reader writes "During a large solar coronal mass ejection, this week's NEAT Comet crossing, gave some spectacular film footage. While no comet with such a small nucleus has ever survived that kind of close solar approach (one-fourth of Mercury's orbit) without fragmenting, this one did-- and is now outward bound on its 370 century roundtrip. These new comet discoveries have filled the log files of the now 70 big robotic telescope projects, most of which are being connected to the internet. The largest ($3 M) research-class one for public use--the Hawaiian Faulkes Project--will see first light in 45 days."

    Reluctant teachers are the types who would keep school dull and disconnected from the real world. It is amazing how, even in adulthood, I find myself going back and actually learning things I was supposed to have learned in school. It always comes in the context of a project I may get involved with. Way back in school, when that bit of knowledge was disconnected from any real world application, I found it hard to keep my focus. When that bit of knowledge relates to my life, I find it extremely fascinating.

    No comet has ever survived this and this one has. I firmly believe that this is an omen from God... that this is the comet that will bring about Armageddon, the end of all things on Earth. This comet is now going to make an outward spiral, followed by a two left turns and four rights, immediately before performing a U-turn, after which it will begin heading towards the Earth, on a course that will bring it within 1 million miles of our planet.

    For those of you who haven't quite followed along, that was:

    • Outward spiral.
    • Left turn.
    • Left turn.
    • Right turn.
    • Right turn.
    • Right turn.
    • Right turn.
    • U-turn
    • Head towards Earth.

    Just when scientists think it has barely passed us by, it will hit a tiny speck of dust that will cause it to bounce off and head directly for some big, black asteroid that we can't see in our telescopes. This asteroid will then head directly for Earth. I believe that this asteroid is going to land right on top of Slashdot's server and we're all going to die. Not from the impact--the asteroid will be composed of styrofoam--but from the lack of Slashdot.

Any terrabiologist worth his salt would quibble with his description of "[the Sun] that makes possible all life on Earth", thinking of undersea volcanic vent ecosystems, and those tiny critters apparently riddling the entire crust. And even basic arithmetic eludes him in


    "this solar observatory has such an enormous field of vision that it can take pictures extending outwards more than 13 million miles [...]. That wide-angle 'lens' spans to nearly one-tenth of the distance to the Earth (93 million miles away[...])."


    because 93/10 < 13, not > 13. Not to mention that the $10 disposable camera I shoot off at keg parties is covering an enormous field of vision, measureless even in parsecs, accounting for up to 30% of the entire Universe. And the entire distance from the Sun to the Earth can be contained in a 0' arc, when I face the Sun.

      For an astronomer, 93/10 is approximately equal to 13 :-)

      He was talking about a camera with a fixed focus (at the distance of the Sun) having an angle of view measurable in linear distance. This is fine, as long as the baseline (ie, you are standing near the Earth, looking at the Sun) is understood. Unfortunately, you forgot that with the snide comment about the 0' arc. The relevant parameter in the field of view is the distance from the sun in the _perpendicular_ direction.

      Other than that, your disposable camera would be impressive, if only it had more than a tiny fraction of the resolution of the SOHO cameras.
