Saturday is Saturn's day. Saturn, a god of ancient mythology, is the planet with the beautiful rings. For 13 years, the Cassini space mission studied Saturn, its rings and moons.

Three beautiful planets - Mars, Jupiter and Saturn - are all visible to the unaided eye. If you have binoculars or a telescope, you can also see some of the moons and other features. Here's a beginner's look at the planets which lie beyond Earth.

The Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn are visible to the naked eye. People have seen them for thousands of years. Other Solar System bodies were discoveries, but who discovered them?

This ice giant is twenty times farther from the Sun than we are. It circles the Sun lying on its side, so each half the planet is dark for over twenty years at a time. It's the planet Uranus, discovered in 1781 by William Herschel who named it George.

Saturn's moon Titan is bigger than the planet Mercury. It's also the only moon with a thick atmosphere. In fact the atmosphere is so smoggy, we can't see the surface. How is Titan like Earth?

The 50th anniversary of the first manned Moon landing was on July 20, 2019, and there were books galore to celebrate it. Apollo 11: The Inside Story tells the fascinating story of how the space race was a battlefront in the Cold War as two competing ideologies vied for supremacy.

The starter's pistol for the space race was fired on October 4, 1957. It was in the form of a small highly-polished sphere that orbited the Earth every 98 minutes. This was the Soviet Union's Sputnik, Earth's first artificial satellite. It shook up the United States, and there was more to come.

Rosetta, the European Space Agency (ESA) spacecraft, traveled for ten years and billions of miles with its lander in order to rendezvous with a comet, and accompany it as it moved through the inner Solar System past the Sun.

Maria Mitchell was a true pioneer woman. She didn't brave a physical wilderness. Hers was the harder job of pioneering higher education for women. She was the first American woman to discover a comet, the first to be elected to scientific societies and the first woman professor of astronomy.

One of the greatest astronomers of all time was a Danish nobleman with a metal nose, who was also a publisher, an alchemist and the Imperial Mathematician. His astronomical observations were the key to the modern view of the Solar System.
