I’ve recently come across the open source software Xplanet, which will render images of the globe with very realistic results.

I render them in 512×256, 1024×512, 2048×1024 and 4096×2048 resolutions. The clouds information is obtained from weather satellites and is typically around three hours old.

I also use monthly map files so that the snow/ice on the planet is more realistic.

On the 13th and 14th December, we’re expecting the best meteor shower of the year.

The Geminids are a meteor shower caused by 3200 Phaethon which should result in around 120 to 140 meteors per hour. On top of this, the best dates to view it are two days before a new moon so the sky should be nice and dark.

The meteors should radiate from the constellation Gemini, which is right next to Betelgeuse in the Orion constellation.

For more information on the Geminids, try the spacedex website.
