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.

“Chicago Tonight” viewer J. Scott Sykora shared this photo of a harvest supermoon eclipse on Sept. 27, 2015.

There hasn’t been a lot to get excited about in 2020, but one bright spot has been the moon, specifically the string of supermoons we’ve enjoyed this spring.

Apollo 8 astronauts were the first to ever witness an earthrise, a view of the planet that put its fragility into perspective and helped propel the environmental movement.

Apollo 13’s astronauts never gave a thought to their mission number as they blasted off for the moon 50 years ago. Even when their oxygen tank ruptured two days later — on April 13.

There hasn’t been a whole lot of good news in 2020, but here’s something to get excited about: Tuesday’s supermoon will be the closest the full moon gets to Earth in 2020, meaning it will look bigger and brighter than any other full moon this year.

Think things are bleak on planet Earth? At lease it’s not raining metal. That’s the kind of bizarre climate scientists recently observed on an ultra-hot exoplanet they’ve dubbed WASP-76b, located 640 million light-years away.
