Researchers were able to determine how the Southern Ring Nebula was created and understand how more than one star led to its 'messy death' by reconstructing the scene that happened thousands of years earlier.
."There is so much detail in its images. We approached our analysis much like forensic scientists to rebuild the scene. "
"We think all that gas and dust we see thrown all over the place must have come from that one star, but it was tossed in very specific directions by the companion stars," Joel Kastner, a team member from the Rochester Institute of Technology in New York, said in NASA's press release. "Knowing the initial mass is a critical piece of evidence that helped the team reconstruct the scene and project how the shapes in this nebula may have been created," the NASA website reads.
