The Necklace nebula, formally known as ‘PN G054.2-03.4’, is a ‘Planetary Nebula’ located at about 15,000 light-years from Earth in the constellation of Sagitta.
In the heart of this planetary nebula, lies a pair of sun-like stars orbiting each other at a close distance of just a few million miles.
So close, in fact, that they complete a single orbit around one another in just 1 day. Over the course of the last 10,000 years, one of the two aging stars devoured its companion as it transitioned from a main-sequence star to a red-giant, a move our sun will experience here in about 4 billion years.
During this transition, the smaller of the two stars continued to orbit inside its companion, which increased its rotation rate, causing it to expel a large portion of its outer envelope of gases into space — forming this ‘elliptical necklace’
Thanks For Watching.
Peace.
