NASA’s Parker Solar Probe shows greater detail in the twin tails of comet NEOWISE, as seen on July 5, 2020. The lower, broader tail is the comet’s dust tail, while the thinner, upper tail is the comet’s ion tail. (NASA / Johns Hopkins APL / Naval Research Lab / Parker Solar Probe /Guillermo Stenborg)

The comet has been delighting sky gazers across the globe. Catch it now, because it won’t swing back our way for another 6,800 years.
