On this day in 1990 – February 23rd – Pioneer 11 crossed the orbit of Neptune on its way out of the Solar System.

The spacecraft went beyond the most distant planet, but since there are dwarf planets and other objects out there, it didn't leave the Solar System.

On this day in 1987 – February 23rd – the light from supernova SN 1987A reached Earth.

The supernova occurred in the Tarantula Nebula in our neighboring galaxy the Large Magellanic Cloud. It was the closest supernova seen in nearly four hundred years. Visible to the unaided eye in the southern hemisphere, it has greatly increased our understanding of this spectacular phenomenon.

On this day in 1968 – February 24th – the discovery of the first pulsar was announced.

A pulsar is a fast-rotating neutron star that emits a beam of electromagnetic radiation. We can only detect it when it's pointing towards us, rather like a lighthouse, so it seems to pulse. A neutron star is the remnant of a massive star following the collapse of its core in a supernova explosion.

On this day in 1966 – March 1st – the Soviet probe Venera 3 landed on Venus, the first Earthly craft to land on another planet.

The probe was entering the atmosphere as ground control lost contact with the orbiting spacecraft. Therefore any data it may have collected couldn't be transmitted.
