All just speculative at the moment. One thing for sure, it is not made of Ice. [/quote] At the moment? You sound like we gonna be able to check it out pretty soon or something. [/quote] the Solar Dynamics Observatory has been gathering spectra from the comet to understand its composition. With all the spacecraft available to observe the comet's close encounter with the sun, scientists have been able to track far more of its torrid travels. The Solar Dynamics Observatory captured the comet as it flitted behind the sun, then re-emerged. One of NASA's two Stereo spacecraft was in position to capture the comet as it crossed the far side of the sun. It too has been gathering data on the comet's composition, Pesnell (project scientist for the Solar Dynamics Observatory at the Goddard Spaceflight Center in Greenbelt, Md.) says. http://www.csmonitor.com/Science/2011/1216/Mystery-of-Comet-Lovejoy-How-d-it-survive-close-encounter-with-the-sun?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+feeds%2Fcsm+(Christian+Science+Monitor+%7C+All+Stories) [/quote] Also, Because the comet survived, researchers now estimate Comet Love Joy's mass to be at least [b]1 billion kilograms, or 1.1 million tons[/b] It's nucleus was initially estimated to be no more than [b]200 meters[/b] across, but now it is more likely that the nucleus measures significantly larger. http://www.csmonitor.com/Science/2011/1216/Mystery-of-Comet-Lovejoy-How-d-it-survive-close-encounter-with-the-sun?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+feeds%2Fcsm+(Christian+Science+Monitor+%7C+All+Stories) [/quote] [/quote] I saw it on a SOHO pic. I don't know if it is the radiation or sensor over exposure, but the blob of comet... it was a very easily see-able size compared to the sun. Like even earth is smaller than that bunch of pixels. Could it be bigger than earth? And why can they see what it is made of, and are just guessing wildly about it's size? [/quote] Not sure bro. And I am not sure whether I would believe much of what they say anyhow. :peace: [/quote]
Survived a temperature of over 1 million cel ?.
Thought comets were made of ice.
