Scientists estimate that the remains of ancient Nova were discovered by Chinese astronomers in 48 BC.
Jakarta, Jurnas.com – A team of international astronomers identified the remains of ancient novae in galaxy clusters.
Using the MUSE Very Large Telescope, scientists found a dead star nucleus that glowed near the center of the Messier 22 spherical cluster found in the constellation Sagittarius, 10,600 light-years from Earth.
When the nova is turned on, hydrogen will explode from the star's surface and the star sheathing will become brighter. The brightness of the leftover remains may last for centuries.
Astronomers estimate that this particular nova was originally seen about 2000 years ago.
"The position and brightness of the remnants matched those from 48 BC in the collection of ancient Chinese astronomers' observations," said Fabian Göttgens, a researcher at the Institute of Astrophysics at the University of Göttingen, which he informed UPI.
"They can see the original Nova in the same place," he added.
Messier 22 is an elliptical globular group, a large cluster of star clusters, each of which is home to hundreds of thousands of ancient stars.
Large Telescope The Southern European Observatory and MUSE are very good at separating and measuring the brightness of different colored lights. So MUSE is very useful in finding a nebula that usually looks bright red.
Because the explosion of the new is so strong, it is 8,000 times larger than the distance between Earth and the Sun, but it is light and rare. Nova has a mass 30 times greater than Earth.
Astronomers describe the remains of ancient New in a new article to be published in Astronomy and Astrophysics.
