Today’s Image of the Day from the European Space Agency features the Necklace Nebula, which is located about 15,000 light-years away in the northern constellation Sagitta.
The nebula was produced by a pair stars about 10,000 years ago, when one star expanded and engulfed the other. As the small star continued to orbit within the bigger star, the giant star exploded, ejecting a ring of debris that forms the Necklace Nebula.
According to ESA, sespite their close encounter, the stars are still furiously whirling around each other, completing an orbit in just over a day.
