As anybody into astronomy probably already is aware of, NASA is keen on sharing incredible photos of our universe. Not too long ago, NASA shared a stunning photo of a nebula generally known as the “Necklace Nebula,” which is described as “a diamond necklace of cosmic proportions.
The nebula—which additionally goes by its less-glamorous title, PN G054.203.4—is situated roughly 15,000 light-years away from Earth close to the constellation Sagitta. What we see now because the nebula was as soon as a pair of tightly orbiting stars much like our Solar. About 10,000 years in the past, the bigger star expanded and consumed the smaller one, a course of scientists name a “frequent envelope.”
The smaller star continued to orbit whereas inside its bigger companion, which elevated their shared rotation price inflicting bits of each to spin outwards. This ring of particles is what seems just like the necklace, and the extra-dense teams of gasoline fashioned what seems like giant diamonds across the nebula’s ring.
The 2 stars are nonetheless there spinning; they’re the small white dot within the heart of the ring. The celebrities are capable of full a complete orbit round one another in simply over 24 hours. Hubble launched a photograph of this similar nebula nearly a decade ago, however the brand new picture is significantly better as NASA used a number of exposures from Hubble’s Extensive Discipline Digicam 3 and superior processing strategies to enhance it.
