At this amount of detail, scientists can detect individual deposits rich in thorium and related elements. Their current observations suggest that thorium was excavated by impacts of asteroids and comets, and then distributed around craters, rather than being deposited by volcanic activity. Analyses of data from the lower-altitude observations are expected to further improve scientific understanding of the origin, evolution and physical resources of the Moon. By the very act of looking at the night sky, we become involved with astronomy. There can be very few people who have never gazed at the night sky and pondered on the mysteries of the Universe and our place within it.
Astronomy tells a fascinating story.
It is a tale made all the more enthralling by the ease with which anyone can participate in astronomical observation. The very word astronomy, conjures up wonderful images in your mind of distant galaxies, exploding stars, comets, meteors, telescopes and yes life elsewhere in the Universe. It may also bring to mind your very first look through a telescope or binoculars. Whatever comes to mind, the subject of astronomy has captured the hearts and minds of virtually every person on the planet at some time or another. So, if you are new to astronomy, take your time in learning your way around the night sky.
