Animation: the formation of a pulsar
A star in a binary star system has collapsed to a neutron star. It begins to gain material from its companion star (known as "accretion"). The infalling matter causes it to speed up and begin emitting high energy radiation, eventually forming a pulsar rotating at up to 1000 times a second.
