![]() | 1961 | Soviet cosmonaut Gherman Titov becomes the second person to orbit the earth on board the Vostok 2 capsule. His 16 orbits take 25 hours 18 minutes making him the first person to spend more than 24 hours in space and the first person to sleep in space. |
![]() | 1967 | British astronomers Antony Hewish and Jocelyn Bell Burnell of Cambridge University use a radio telescope to study a scintillation effect on radio sources caused by clouds of electrons in the solar wind. One of their recordings shows a regularly pulsing source with a period of 1.337 seconds in the wrong part of the sky, away from the sun. Initially it was thought that the signal was human-made, from a spacecraft, or evidence of an extraterrestrial civilization. Its true nature, the discovery of the first pulsar, is not determined until 6 months later. |
