Britain holds its first general election with one vote each

A general election was held across the United Kingdom. It was the first since plural voting was abolished. Before this, some people could vote more than once, and special seats for universities were also scrapped. The Labour Party stayed in power, but its majority in the House of Commons shrank from 146 seats to just 5, while the Conservative Party gained 90 seats.

Work begins on the Hagia Sophia in Constantinople

Byzantine emperor Justinian I began building a new great church in Constantinople, now Istanbul in Turkey. It replaced an earlier church that had burned down only weeks before. The Hagia Sophia, meaning 'Holy Wisdom', was finished in 537 and had the largest indoor space in the world. Its design inspired many later churches and mosques. It later became a mosque, then a museum, and is now a mosque again.

The Gutenberg Bible is traditionally said to be published

This is traditionally given as the date the Gutenberg Bible was published. Johannes Gutenberg printed it in Mainz, in present-day Germany, using metal letters that could be moved around and reused, called movable type. It was the first major book printed this way in Europe and began the age of printed books in the West. Of the 158 or 180 copies printed, 49 still survive, at least in large part.

Light from a nearby exploding star, Supernova 1987A, reaches Earth

Light from a supernova, the huge explosion of a star, reached Earth. It happened in the Large Magellanic Cloud, a small galaxy that orbits our own Milky Way. It was the closest supernova seen since 1604, and the first that modern astronomers could study in great detail. It was named SN 1987A because it was the first supernova discovered that year.
