The 2km-wide relic has been traveling to meet our star for over a million years. But the “dinosaur bone of solar system formation,” as senior research scientist at Johns Hopkins University, Carey Lisse, dubbed it, did not shine as bright after its slingshot encounter around the sun on Thursday, forcing scientists and stargazers to conclude the celestial body had lost its tail and nucleus.
Karl Battams of NASA wrote on the space agency’s dedicated ISON blog about the confusion that the celestial body has caused.
“After impressing us yesterday, comet ISON faded dramatically overnight and left us with a comet with no apparent nucleus,” Battams said, also mentioning the deluge of calls he and the team had received from reporters, despite not being able to provide them with 100 percent clarity.
“As the comet plunged through the solar atmosphere, and failed to put on a show… we understandably concluded that ISON had succumbed to its passage and died a fiery death. Except it didn't! Well, maybe...,” he continued.
There were conflicting theories about the comet’s fate, but what emerged later in the photographic evidence forced everyone to backtrack.
But claims of the ISON’s demise were later challenged with photographic evidence, as scientists saw a faint, but still bright glow of what they believe to be a piece of the comet.
“Now, in the latest LASCO C3 images, we are seeing something beginning to gradually brighten up again. One could almost be forgiven for thinking that there's a comet in the images!”
“We have a whole new set of unknowns, and this ridiculous, crazy, dynamic and unpredictable object continues to amaze, astound and confuse us no end,” Battams finished, asking everyone to be patient with further guess work. He added that if the glow is indeed the comet, we will be seeing it in the night sky in a matter of days.
NASA was not alone in retracting its earlier assessments: the European Space Agency stepped back from its earlier claims of ISON’s end as well.
However, scientists do not wish to make any further predictions as to its future at this point, because the comet could still just as easily stop releasing material and die out, if it indeed has not burned up after encountering the sun’s corona.
