What has happened to the moon of Saturn? The moon of Saturn is hidden behind the rings. In 2010 the robotic Cassini spacecraft looked across the Solar System's most famous rings. The thin F ring on the outside is one of the rings visible in the foreground. Although it seems to be hovering over the rings, the moon is far behind them. One of the smaller moons in the universe is called Janus and it is 180 kilometers across. The larger moon, Rhea, is far from the camera. There are gaps in the rings that allow the top of Rhea to be seen. After more than a decade of exploration and discovery, the Cassini spacecraft ran out of fuel and was directed to enter the atmosphere of Saturn.

A year of sunrises.

Does the Sun always rise in the same direction? No. The direction toward the rising Sun changes as the months change. The image shows the direction of sunrise every month in the year 2021. The camera is facing east, with the north and south facing it. The top image was taken in 2020 December, while the bottom image was taken in 2021 December, making 13 images in total. The Sun rises furthest to the south of the east on the December and June solstices, and furthest north of the east on the June solstice. The first day of winter in the North is considered an official change in season in many countries. The winter season on the Earth's surface and atmosphere is the most cold of the year.

There are updates on the James Webb Space Telescope.
