DescriptionComet NEOWISE (2020-45-4729).png |
English: 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 August 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 (4.8 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. Comet NEOWISE won’t pass through the inner solar system for another nearly 7,000 years. |

Headline | Whether it’s a surprise asteroid, colorful aurora or a heart-stopping eclipse, the landscape of the night sky is constantly changing. When a new visitor appears in view, it’s guaranteed to grab the attention of professional astronomers and casual sky gazers alike. Well, consider the Hubble Space Telescopethe paparazzi of the sky, as it’s managed to snap the closest images yet of the sky’s latest visitor to make headlines, comet C/2020 F3 (NEOWISE), after it passed by the Sun.Comet NEOWISE is considered the brightest visible from the Northern Hemisphere since 1997’s Hale-Bopp. It’s estimated to be traveling at a whopping 40 miles per second, or 144,000 miles per hour. The comet’s closest approach to the Sun took place on July 3 and it’s now heading back to the outer parts of the solar system, not to pass through again for another 7,000 years or so. |
