There are very strange objects in the universe, due to their rarity, and among them is a binary system formed by two pulsars.<\/p>\n

That system, known as PSR J0737\u22123039, was discovered in 2003<\/strong> by astronomer Marta Burgay's team from the Parkes Observatory in New South Wales, Australia. That system, 1,630 light-years from the Solar System, was the first known to consist of two pulsars<\/strong>, called PSR J0737\u22123039A and PSR J0737\u22123039B. Pulsars are rapidly spinning neutron stars that generate strong emissions of electromagnetic radiation from their poles. A pulsar is a very rare object compared to others: only 3,200 are known<\/strong>, and a second double pulsar (PSR J1913+1102) was not discovered until 2020.<\/p>\n

About this very strange binary system, which tests Einstein's theory of general relativity<\/strong> by allowing its behavior to be examined over very short periods of time, the YouTube channel Kosmo<\/a> has published a video with excellent graphic quality showing what PSR J0737\u22123039 is like<\/strong> and also talking about neutron stars (if it doesn't load automatically, you can enable the English audio track in the bottom bar of the player):<\/p>\n
