Hubble Snaps Close-Up of Celebrity Comet NEOWISE The Hubble Space Telescope has snapped the closest images yet of the sky's latest visitor to make headlines, comet NEOWISE, after it passed by the Sun. This is the first time Hubble has photographed a comet of this brightness at such resolution after this close of a pass by the Sun. This ground-based image of comet C/2020 F3 (NEOWISE) was taken from the Northern Hemisphere on July 16, 2020. The inset image, taken by the Hubble Space Telescope on Aug. 8, 2020, reveals a close-up of the comet after its pass by the Sun. Hubble’s image zeroes in on

Hubble Snaps Close-Up of Celebrity Comet NEOWISE The Hubble Space Telescope has snapped the closest images yet of the sky's latest visitor to make headlines, comet NEOWISE, after it passed by the Sun. This is the first time Hubble has photographed a comet of this brightness at such resolution after this close of a pass by the Sun. This ground-based image of comet C/2020 F3 (NEOWISE) was taken from the Northern Hemisphere on July 16, 2020. The inset image, taken by the Hubble Space Telescope on Aug. 8, 2020, reveals a close-up of the comet after its pass by the Sun. Hubble’s image zeroes in on the comet’s nucleus, which is too small to be seen. It’s estimated to measure no more than 3 miles ( kilometers) across. Instead, the image shows a portion of the comet’s coma, the fuzzy glow, which measures about 11,000 miles (18,000 kilometers) across in this image. The comet photos were taken after NEOWISE skimmed closest to the Sun on July 3, 2020, at a distance of 27 million miles (43 million kilometers). Other comets often break apart due to thermal and gravitational stresses at such close encounters, but Hubble’s view shows that apparently NEOWISE’s solid nucleus stayed intact. Comet NEOWISE is considered the brightest visible from the Northern Hemisphere since 1997’s Hale-Bopp. It’s headed beyond the outer solar system, now traveling at a whopping 144,000 miles per hour. It will not return to the Sun for another nearly 7,000 years.
