Comet ISON, which the scientists were hoping would eventually be visible to the naked eye, is believed to have been vaporized after flying too close to the sun.
The comet, which was moving faster than 217 miles per second as it approached the sun, is believed to have been vaporized.
What isn't clear at this point is whether the heat destroyed the entire comet.
The one thing scientist do know about ISON is that it is no ordinary comet and if any of ISON did survive the close encounter, it should be visible to the naked eye in the next week or so.
