Merry Christmas To Readers

Let's not let the latest variation of this virus ruin the holiday spirit.

The James Webb Space Telescope will be on it's way. It will be in orbit around the sun, unlike the Hubble Telescope which orbits the earth. This will make it possible for one side to always face the sun, where the solar panels will be located. The other side will always be extremely cold.

This makes it possible to operate infrared sensors. A lot of information comes from the universe in the form of infrared, or heat. It is very difficult to gather this information on earth, or in earth orbit, because it is drowned out by the heat all around us.

Remember that there was a posting years ago about how we could be getting a lot more information about the universe in infrared:
