The farside of the moon is always turned away from the Earth. Its appearance remained a mystery until 1959, when the Russian spacecraft Luna 3 was able to travel behind the Moon and send back the first photographs.
Although the farside looks similar to the moon’s nearside, there are obvious differences. It has few maria, because the lunar crust is thicker than on the nearside, making it difficult for lava to seep through into the impact basins left by colliding space rocks.
The north and south poles were the last parts of the Moon to be mapped. This was done by the Clementine spacecraft in 1994.
Mosaic maps, made by assembling the thousands of images that Clementine sent back, showed that some of the polar craters are permanently shadowed from the Sun’s rays.

The oldest star chart known may be a carved ivory Mammoth tusk that was discovered in Germany in 1979. This artifact is 32,500 years old and has a carving that resembles the constellation Orion. A drawing on the wall of the Lascaux caves in France has a graphical representation of the Pleiades open cluster of stars.

Impact Craters
When a Metorite collides with Earth it can form an impact crater – a bowl – shaped hollow in the Earth’s surface. Space rocks have produced in this way throughout Earth’s life, especially when the planet was young, about 4 billion years ago. Space rocks do not have to hit Earth to have a devastating effect. On june 30, 1908, there was an explosion 3.5 miles up in Earth’s atmosphere, above...

Radio Astronomy
Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light. At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.

Black Holes Explained
The most Bizarre objects in the Universe, black holes are aptly named – they emit no visible light at all. And yet, most black holes are the end state of the most brilliant objects in the cosmos; giant stars that go supernova. The super compressed core that remains after the explosion has such strong gravity that even light cannot escape it – so the object is black.
