I've always liked advent calendars, so here's another astro advent for this year. Starting tomorrow, it's based on the days up to Christmas, but will be full of astronomy events and interesting pictures. Sorry about having no windows to open - it'll be click-the-links instead.
And to everyone, Greetings and Good Wishes for whatever winter holidays you celebrate.

1Galileo Galilei made the first detailed observations of the Moon in 1609 between November 30 and December 18.Four of the drawings were then engraved for publication in March 1610.Â
Here are two of Galileo's drawings of the Moon. He made them while observing using a small telescope with 20x magnification.

2A winter scene with Orion prominent in a starry sky above a bridge over the river Lielupe in Latvia.Due to the long exposure, drifting ice shows up as streaks in the river. And, beautifully, there are stars reflected in the river. The sky beams are from a church in the village whose lights line the horizon.

Fascinating Mona, what a great idea for Advent, and love the Latvia photo, just beautiful.
Have sent you a message through the internal mail system by the way, the Forum PM facility seems to have disappeared. Or perhaps that is only my connection. 
I really enjoy Advent, it is such a wonderful time of year isn't it...

5 Northern lights in northern Norway photographed by noted aurora photographer Ole Salomonsen.The northern and southern lights are one of Earth's most splendid spectacles. They're created when charged particles from the Sun interact with particles of our atmosphere at an atomic level.
