The interplay of two doomed stars has created this spectacular ring adorned with vibrant clumps of fuel—a diamond necklace of cosmic proportions. Fittingly generally known as the “Necklace Nebula,” this planetary nebula is positioned 15,000 light-years away from Earth within the small, dim constellation of Sagitta (the Arrow).
A pair of tightly orbiting sun-like stars produced the Necklace Nebula, which additionally goes by the much less glamorous identify of PN G054.203.4. Roughly 10,000 years in the past, one of many getting old stars expanded and engulfed its smaller companion, creating one thing astronomers name a “widespread envelope.” The smaller star continued to orbit inside its bigger companion, rising the bloated big’s rotation price till massive components of it spun outwards into house. This escaping ring of particles fashioned the Necklace Nebula, with significantly dense clumps of fuel forming the brilliant “diamonds” across the ring.
The pair of stars which created the Necklace Nebula stay so shut collectively—separated by solely a number of million miles—that they seem as a single vibrant dot within the middle of this picture. Regardless of their shut encounter, the celebrities are nonetheless furiously whirling round one another, finishing an orbit in simply over a day.
Hubble beforehand launched a picture of the Necklace Nebula, however this new picture makes use of superior processing methods to create an improved and contemporary view of this intriguing object. The composite picture contains a number of exposures from Hubble’s Broad Discipline Digital camera 3.
