Parker: The Solar System from Near the Sun
Explanation: If you watch long enough, a comet will appear. Before then, you will see our Solar System from inside the orbit of Mercury as recorded by NASA 's Parker Solar Probe looping around the Sun . The video captures coronal streamers into the solar wind , a small Coronal Mass Ejection , and planets including, in order of appearance, Mercury , Venus , Saturn , Earth , Mars , and Jupiter . Between the emergence of Earth and Mars, Comet Tsuchinshan-ATLAS appears with a distinctive tail. The continuous fleeting streaks are high energy particles from the Sun impacting Parker's sideways looking camera . The featured time-lapse video was taken last year during Encounter 21 , Parker's 21st close approach to the Sun. Studying data and images from Parker are delivering a better understanding of the dynamic Sun's effects on Earth's space weather as well as humanity's power grids, spacecraft, and space-faring astronauts.
