This view of Neptune, as seen through the Hubble Space Telescope, is helping planetary scientists gain some insight into the weird and wild weather that is a hallmark of the eighth planet from the sun. On Neptune, winds blow at 1500 kilometres per hour and huge storms - some the size of Earth itself - come and go with regularity. How, precisely, Neptune's weather is driven is a mystery since the Sun, which drives the Earth's weather, is 900 times dimmer there than on Earth.

The magnificent reflection nebula NGC 2023 lies nearly 1500 light-years from Earth. It is located within the constellation of Orion (The Hunter), in a prestigious area of the sky close to the well-known Flame and Horsehead Nebulae. The entire structure of NGC 2023 is vast, at four light-years across. This NASA/ESA Hubble Space Telescope picture just takes in the southern part, with the subtle shades of colour closely resembling those of a sunset on Earth.
