A black hole changes the color of stars in the Milky Way galaxy and people are wondering what is going on. A discovery in the astrophysical journal of November 12 allowed Michal Zajacek of the Polish Academy of Sciences to note the phenomenon. A supermassive black hole called Sagittarius A sits near the middle of the galaxy. This place was pumping gas that literally siphoned off the outer layers of various stars in the Milky Way. Now that might sound like a five alarm problem, but there is nothing to worry about just yet. To hear Zajacek say it, the two large gamma gas bubbles don’t travel much further than the immediate area. In fact, it is argued at the moment that scientists are now more easily able to hypothesize when the black hole formed. Speaking to Science News, the astrophysicist explained how the red giants are prime targets.
“The jet acts preferentially on the big red giants,” he says. “They can be effectively eliminated by the jet.”
Their reports go on to say that the size and shape of these stars make them very sensitive to gamma gases. Other red giants can grow up to 100 times the size of our Sun. At this size, removing the red outer layer would put them in immediate danger. As they pass through these gases, the stars burn blue instead of red, which explains the change in color.
Maybe one day the explorers of our planet will be able to investigate these kinds of movements. Other contemporaries in the scientific community have argued that there must be more to this situation than just exposure to gas. Only time will tell.
In other space news, the United States recently unveiled its Space Force moniker. They will be known as Guardians, and the latest branch of the military described it on Twitter. “Today, after a one-year process that has produced hundreds of submissions and research involving space professionals and members of the general public, we can finally share with you the name we will be known by: Guardians.
Do you think we’ll have galaxy-wide travel in the next 100 years? Let us know in the comments!
