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.

Random APOD Generator is almost Hyperspace.

The first day of winter in the north and summer in the south is the December's solstice. The sun's position in the sky is used to mark the seasons, the solstice and the equinox. At this time of the year.
The Sun is at its maximum southern declination of -23.5 degrees today at 15:59 UTC, while its right ascension coordinate is 18 hours. The constellation Sagittarius is near the center of the Milky Way. It's really hard to see the sun against the background stars and nebulae in the daytime. The images of our fair galaxy were taken under dark skies and then combined into a panoramic view. The Sun was superimposed as a brilliant star at the northern winter solstice position, close to the center of the Milky Way.

There is a graduate student research position open.
The picture is tomorrow's X launch.
