Last night was nice and clear, so I grabbed my gear and drove about ten minutes west of town, hoping to catch Comet C/2020F3 (NEOWISE).
It was about 10:30 when I got to my spot, and the sunset was still too bright to see the comet. I noticed Jupiter on the other side of the sky, so I snapped a couple shots of it first. I’m not 100% sure, but I think I got all four Galilean moons in the shot, too.
Then the sun set enough, and I swung back around to face northwest.
As I was getting ready to pack up, I noticed a haziness to the northeastern sky. I knew thanks to SpaceWeather.com that a coronal mass ejection had just arrived, triggering some aurora. So I put my widest lens on my camera and snapped a few more shots.
All in all, a good night. I even got to wave at the International Space Station as it went by.
Thanks to extensive computer simulations, the researchers have calculated that the current asymmetry [in the counts of Trojan asteroids] could only have occurred if Jupiter was formed four times further out in the solar system and subsequently migrated to its current position. During its journey towards the sun, Jupiter’s own gravity then drew in more Trojans in front of it than behind it.
