But a recent analysis, published in the journal Nature Astronomy, suggests otherwise.Red in color, the celestial body has a long, cigar-like shape and weird spin pattern, like a bottle lying on the ground and spinning on its side.More on Geek.com:Scientists Find Tiny Fragment of Comet Inside a MeteoriteNASA Telescope Captures Stunning Sight of 2018’s Brightest CometRubber Duck-Shaped Comet Has Been Blown Apart and Reborn Stay on targetlast_img
