What's Up? We've all seen the sun from Redlands and maybe the moon on a warm evening, but what else is up there? Quite a lot actually. Here's the place to find out what in Redlands!
Here is a constantly updated image of the Sun! The picture is taken in a very specific wavelength of red light (called H-alpha) emitted by hydrogen gas - the most common component of the Sun. The images are updated once a minute. If it is blank, clouds may be obscuring the Sun, or it has already set.
Here are daily viewing times for orbiting spacecraft you can see from your own front yard. For cities other than Redlands, or the rest of the world, go to the main website at: Heavens-Above.
The International Space Station (ISS).
Iridium Communication Satellite Flares.
The Hubble Space Telescope (HST).
Other satellites, Tumbling boosters, etc. brighter than magnitude 4.0.
