Descrizione
English: Animation showing neutron star and accretion disk evolving into a millisecond pulsar, with magnetic fields.
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.
Deutsch: Animation: Die Entstehung eines Pulsars:
 Ein Stern in einem Doppelsternsystem kollabiert zu einem Neutronenstern. Es beginnt Material von seinem Begleiter zu ihm zu strömen (Akkretion). Die einfallende Materie verursacht eine Beschleunigung und das Aussenden hoch-energetischer Strahlung. Schließlich ist ein Pulsar entstanden, der sich bis zu 1000 mal pro Sekunde dreht.
Čeština: Animace vzniku pulsarů
中文（简体）：动画：脉冲星的形成。
双星系统中的一颗恒星塌缩成为中子星并从其伴星中吸收物质。因此中子星加速旋转并放出每秒一千次左右的脉冲。
