Explaining The Universe on Instagram: "A pulsar is a type of neutron star that emits beams of electromagnetic radiation—usually in the form of radio waves, but sometimes also visible light, X-rays, or gamma rays. These stars are the ultra-dense remnants of massive stars that exploded as supernovae. When the core collapses, it leaves behind an object only about 20 kilometers in diameter, yet with a mass greater than the Sun. • #explore #reels #viral #universe #explaining #space"
