Today, we are witnessing an exciting event in the field of astronomy - the eclipse of an X-ray binary star system known as 4U 1820-30! This binary system consists of two stars which orbit around each other - one is a neutron star and the other is a low-mass star. Every few months, the neutron star passes in front of the other star, causing an eclipse in the X-rays that the system emits. This event is known as an eclipsing X-ray binary, and it is a rare and fascinating phenomenon. For the next few weeks, astronomers around the world will be tracking this eclipse and gathering data in order to better understand the nature of these binary systems. This is a truly incredible event, and we are excited to see what new discoveries come out of it!
