Most SNRs contain the cold remains of a single star at its center. Now some scientists see this object as a superbubble created by the birth of a cluster of as many as 200 stars at its center. This roughly rectangular region is a great example of how innovative the three-dimensional imaging of LaRosa et al. This area was shown as empty by earlier attempts at mapping. It then appeared out of nowhere with the new 3-D imaging.
Most scientists think at the moment that it is a massive region of ionized gas.
There will be more discoveries to come in the study of our galactic center. Discoveries here will help astronomers to understand how other galaxies work. Lecture Notes in Physics. A Wide-Field 90 Centimeter VLA Image of the Galactic Center Region.
