NASA’s Webb Indicates Several Stars ‘Stirred Up’ Southern Ring Nebula
The elongated, curved geometries of the Southern Ring Nebula were created by at least two, and maybe three, additional undiscovered stars, according to some of the initial data from NASA’s James Webb Space Telescope. Additionally, astronomers were able to precisely determine the mass of the central star before it formed the nebula for the first time by combining Webb’s infrared photos with preexisting data from the ESA’s (European Space Agency) Gaia satellite. To arrive at these conclusions, a group of over 70 academics under the direction of Orsola De Marco of Macquarie University in Sydney, Australia, examined Webb’s 10 extremely detailed exposures of this fading star.
According to their estimations, the Sun’s mass was almost three times that of the central star before it ejected its layers of gas and dust. Following such ejections, it is currently around 60% of the mass of the Sun. The team was able to rebuild the image and make projections about how the shapes in this nebula would have been formed by knowing the beginning mass, which is an important piece of evidence.
