Pulsar

A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. The name "pulsar" is a portmanteau of "pulsating star," reflecting the fact that these objects appear to pulse when viewed from Earth. In Hebrew, a pulsar is called פולסר (pronounced "pul-sar"). In Spanish, it is known as púlsar, while in German, it is referred to as Pulsar. Pulsars are incredibly dense, with a mass greater than that of the Sun compressed into a sphere with a radius of about 10 kilometers. They are formed from the remnants of supernova explosions and are known for their extreme rotational stability, making them useful as natural clocks in various astronomical and astrophysical applications. The first pulsar was discovered in 1967 by Jocelyn Bell Burnell and Antony Hewish, marking a significant milestone in the field of astrophysics.
