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.
Lammas is a Christian harvest festival celebrated on 1 August, but its origins are pagan. In the Gaelic tradition, it was Lughnasa. Lying midway between the June solstice and the September equinox, it was one of the four 'cross quarter' days of the Gaelic year.
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.
William Herschel discovered the planet which was named Uranus after the ancient Greek sky god. Although Uranus has at least 27 moons, most of them weren't discovered until at least the twentieth century.
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.
By the late 19th century all the outer planets were known to have moons, yet Mars had none. At last, in 1877 American astronomer Asaph Hall found two Martian moons. Why did it take so long? And why did Hall call them Fear and Terror?
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.
It's the place where time begins: The Royal Observatory, Greenwich, England. Here you can stand on the Prime Meridian of the world with one foot in the western hemisphere and the other in the eastern hemisphere. It represents over three hundred years of astronomical and maritime history.
