Scientists have finally solved the mystery surrounding the glowing blue ring of light which is not something that astronomers have seen before.
Astronomers have spent years trying to understand why there was a circle of blue light around a mysterious object on Earth, analyzing images taken by telescopes both on land and in space.
Scientists now believe how they created the blue light, ending a 16-year-old mystery and detailing the history of a spectacular and dramatic object in a distant place.
Astronomers argue that the blue ring is not actually a ring, but a cone. A cloud of fluorescent debris was probably formed after a sun-like star swallowed a small companion, and as a cone faced the earth directly, it looked like a ring from here.
(The ring is not strictly blue, but is a way of representing otherwise invisible light instead of color that surrounds the object.)
This observation is the first time that astronomers have observed a rare stage in the evolution of stars that occurred thousands of years after they began, and they probably lasted for thousands of years, a short period of time on the scale of stars.
These two stars began life floating in space, but when the Sun-like star expanded and came closer to another star, the younger of the two began to scatter elements from its larger siblings.
Eventually, as the smaller star swallowed up, the collision triggered a cloud of debris that split from the smaller star by a disk gas – creating two cone-shaped debris clouds.
The hydrogen molecules in the wreckage were then excited by the shock wave, causing them to glow with ultraviolet light, giving the cloud its title.
Lead study author Kerry Hadley said: “The fusion of the two stars is fairly common, but as the emission from them expands and cools in space, they quickly fade into a lot of dust, which means we don’t really see it,” said lead study author Kerry Hadley. Ellen Lee is a postdoctoral scholar in physics from David and Caltech.
“We think this object represents a late stage of these transient events, when the dust finally clears and we have a better view,” Howdley says. “But we also caught it before the process went too far; over time the nebula will melt into the interstellar medium and we can’t say anything happens.”
Scientists have been amazed for years since the mystery became clear. Mark Sebert, an astrophysicist at the Carnegie Institution for Science and a member of the Jack LX team, said, “Every time we thought we’d find out, we’d say, ‘No, that’s not right.'” Says.
“It’s a scary thing as a scientist. But I also like how unique the subject is and the effort that so many people put into it.”
While trying to understand the cause of the star, scientists suggested a number of ideas. Using Caltech’s Hale Telescope at the Palomara Observatory near San Diego and Hawaii’s WM Cake Observatory, they tried to find evidence of a shock wave around the star so that they understood that any cloud was sent into gas.
Later, it was speculated that the star could destroy a nearby, invisible planet, but data from the habitable zone Planet Finder, published in 2013, proved that there were no objects orbiting the star.
Although it has taken a surprisingly long time to discover the cause of blue rings, the use of new technology means older programs are still releasing new information.
“Whenever you survey the sky at new wavelengths, you will inevitably discover many years later and beyond,” said Christopher Martin, a professor of physics at Caltech and former chief investigator at Galaxy.
