Illustration, close up of rocky, potato-shaped body of a comet with detailed, cratered surface at the bottom right. A glowing ray emanates from the rocky surface like sunlight through clouds. It extends from the comet’s surface across the image to the left. This represents water ice being vaporized by the heat of the Sun. There are small bright dots within the ray, representing fragments of the comet. The words Artist's Concept appear at the bottom left.

NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence … Continue reading NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
