NASA recently shared a mesmerising picture of the “Necklace Nebula”, which was created by a pair of tightly orbiting Sun-like stars. About 10,000 years ago, an ageing star expanded to the point where it was immersed into its companion star. The pair of stars orbiting closely together produced the nebula creating bright knots of gas that resemble diamonds in a necklace. Measuring 12 trillion miles wide, this pair can orbit one another in a little over a day.
