Is Comet ISON a UFO? Hubble's scientists do a reality check
Those were apparently questions on the minds of some folks last month, thanks to a flurry of videos and blog postings based on imagery from the Hubble Space Telescope's archives. The hoohah got hot enough to merit an official response, posted to the Space Telescope Science Institute's archive website and its ISON Blog.
It all started with a series of images captured by Hubble's Wide Field Camera 3 UVIS instrument on April 30. Various exposures were combined to produce a widely distributed color picture of Comet ISON against a background field of stars. When Internet sleuths took a close look at the archived image, it looked as if there were three separate objects hiding in the glare of ISON's coma.
Was ISON breaking up? Was the comet being escorted by two alien spacecraft? No. Just no.
Richard White, principal investigator for the Mikulski Archive for Space Telescopes, explained that the image was a composite, created by averaging the data from three separate camera exposures. The three objects are just different views of Comet ISON's nucleus.
"The comet itself does not have three pieces," White wrote. "They are an artifact from adding up the separate exposures. The comet does not look the same in each exposure because both the comet and the Hubble telescope are moving during the exposure. The comet is blurred, just as a picture taken out the window of a moving car will be blurred."

That is a total crap samwich! I'll buy it's not a giant spaceship but WHAT THE HECK is orbiting the comet in the last video NASA released? I can tell you what it is NOT and it is not a parallax anomaly. I have a telescope and I know what a parallax anomaly looks like. And parallaxes don't cast shadows on the "comet" and the "comet doesn't cast shadows on parallaxes. So please don't insult my intelligence. ISON my not be a spaceship but something is coming in with this comet. And whatever it is it wasn't made on planet Earth.

Learn how space maging works people. This is a pre-processed image of 3 different exposures before processing. No "UFO" nonsense needed. Get real for Pete's sakes.

You mean Ison is not the alien messiah come to wisk the doomtards and crystal huggers away to the land of dragons and hot pockets?........damn
