It is not a coincidence that planets line up. All of the planets are in the plane of the ecliptic. Earth dwellers are likely to see the planets in a single band when viewed from inside the plane. It is a coincidence that three of the bright planets are in the same direction. The coincidence was captured earlier this month. The planets Venus, Saturn, and Jupiter were all pictured together in a line just after sunset from the San Fermo Hills. Earth's Moon is joining the alignment with the more distant Uranus. There are clouds in the sky towards the Sun. The planetary alignment should continue for the rest of the month as the comet fades.

There is a graduate student research position open.
Tomorrow's picture is a comet fireball.

This picture was supposed to show a comet. There were images of the comet of 2021. The universe had other plans. A bright object so bright it could be called a fireball streaked through the sky just below a comet. The comet's coma was more green than the meteor's flash. The comet's green was likely caused by diatomic carbon ejected from the comet's city-sized nucleus. The images were taken 10 days ago. The town of Lassen is in California. The fireball was on the edge of the shower, which peaked a few days later. After reaching naked-eye visibility last week, comet Leonard is now moving into southern skies.
