Recordings - The planet Jupiter
It is the largest planet in our solar system and almost approaches the luminosity of Venus. That is why he is sometimes confused with her. However, a look through a telescope reveals it immediately by its two distinctive cloud bands and of course the 4 bright moons. These are also called the Galilean moons after their discoverer. They change their position every hour, so that Galileo Galilei tried for a long time to enable precise time measurement with them. A Jupiter day lasts just under 10 hours, which is why one can admire the entire surface in one night under favorable conditions.

That evening the sky was particularly clear and calm. The scintillation was very low and enabled particularly detailed images.

Jupiter is particularly high in the sky in 2011. Interestingly, the southern equatorial band (top of image) is visible again. In 2010 it was covered by a layer of ammonium crystals and was therefore not visible (see images below).

Jupiter on February 26, 2004 at 10:36 p.m. CET with the moons Europa and Io.
On March 31, 2004, Jupiter's moon Io passed in front of its planet between 10:00 p.m. and 11:50 p.m. CET, casting a shadow on the surface of Jupiter. This allows the flyby to be seen indirectly, as Io is too faint to see directly in front of Jupiter's bright disk. | |||||
