Heheh. Well. . . no. Neither can I!
When it comes to Cosmology I prefer the practical geological parts to the complicated sums to work out densities, intercept routes for spacecraft and so on, but obviously both aspects are essential if you want to make it in the field. I would be getting out my 'scope this evening to look at Saturn and Jupiter. Both of them are in great position- you'll probably see them this evening if you're on the Northern Hemisphere. You can actually use simple binoculars to see Saturn's rings- Galileo did it with a homemade telescope in the 1600s, and most binoculars are actually superior. If you look the the West then you can see them, sliding down in a diagonal sweep like this: \
This is awesome information
Please let us known when Mar's is in retrogade, will ya
i found this interesting .... Psusennes I
Astronomy Lecture Tutorial

In our observations of stars last week we saw different colors in the stars. What is the primary property that determines star color for the stars that we see? What is the literal Greek meaning of the word “planet”? Why?
Last Thursday we viewed the moon fairly close to Antares. In what constellation will the moon be found when it is full this Wednesday. You can figure this out using the planisphere.
Sketch the position of Mars against the background of stars in the sky that shows the retrograde motion for Mars.
In the Ptolemaic model of the solar system, draw a diagram of Mar’s orbit around the earth that shows retrograde motion.
Draw the orbit of earth and Mars around the sun in the Copernican model that explains the retrograde motion of Mars.
Galileo made an important discovery with his telescope which showed that something else in the universe is the center of a system. Describe his discovery.
The Ptolemaic and the Copernican models for the solar system are purely geometric: i. e. they don’t invoke any physical laws. Isaac Newton (1642-2747) was the first to develop physical laws that govern planetary motion – the same laws that govern trucks and cars on earth. Describe these laws and discuss a demonstration of one of these laws.
