THE SUPER-SIZED NUCLEUS OF COMET NEOWISE: Now we know why Comet NEOWISE (C/2020 F3) is so bright. It has an unusually large nucleus. Infrared data from NASA's NEOWISE spacecraft suggest that the comet's core of ice and dust is 5 km wide. This bodes well for the comet's visibility in the weeks ahead.
