The huge conundrum known as the ‘Milky Way galaxy’ measures roughly 100,000 light-years in its diameter, meaning enough to be sure that astronomers will never get to explore it all. But even so, it’s nice to see that they’re doing their best, and the new James Webb Space Telescope (JWST) will continue to offer tremendous help in the process.
The X-ray telescope eRosita revealed huge bubbles expanding from our galaxy a few years ago, baffling astronomers. The supermassive black hole Sagittarius A* was known to cause the huge bubbles, and two models explain the weird structures: Fermi and eRosita bubbles.
A foreign source?
Phys.org speaks about a new study published in Nature Astronomy indicating that there could be a foreign source for at least a part of the metal content present in the Fermi bubble high-velocity clouds. Scientists come up with the suggestion after realizing that the metal content in question doesn’t match the material that exists at the core of our Milky Way galaxy.
The Fermi bubbles high-velocity clouds are gas cloud formations existing inside the Fermi bubbles, meaning those gas formations that are made of plasma that extend beyond the Milky Way galaxy itself.
Years of research might be needed to determine the possible foreign source that scientists are talking about, which means that we’ll just have to get ourselves some patience. It seems to be anyone’s guess what that foreign source may be.
The supermassive black hole from the center of our galaxy, namely Sagittarius A*, plays some positive roles, although black holes are generally regarded as extremely destructive objects. There’s no wonder why NASA plans to study Sagittarius A* in more detail using the James Webb Space Telescope (JWST).
James Webb revealed the first full-color images of the distant Universe just about two weeks ago, and the world was pretty fascinated by the results.
