Astronomers recognise 88 constellations or star pictures in the sky. About half of the constellations date back several thousands of years to the ancient Greeks or to even earlier times. Ancient constellations currently visible in the evening sky include Sagittarius the Archer and Scorpius the Scorpion.
On this day in 1938 the American actor Orson Welles produced and also narrated a radio production of War of the Worlds. Like the science fiction novel on which the play was based, it told of the invasion of Earth by Martians, but with the action moved to New Jersey and New York City American astronomer Percival Lowell thought that the Martian canals that he mapped indicated intelligent life on the planet.

Cetus the Sea Monster is low in the eastern sky in the early evenings. One of its stars, Tau Ceti, is among the nearest to our Sun at a distance of 12 light years.

There are often reports of people seeing lights quickly streaking quickly in the night sky. If the light is relatively faint it is a meteor, while if it is brighter it is a fireball or bolide. Only if the small rock that causes the fireball reaches the ground is it called a meteorite.
