The astrophysicists from the University of Kansas have just discovered an extremely rare type of galaxy for the very first time. This will definitely change the experts’ understanding of how galaxies are dying.
CNET notes that during the 234th meeting of the American Astronomical Society, Allison Kirkpatrick revealed her discovery of “cold quasars”, which are incredibly bright, dying galaxies in the farthest reaches of the cosmos.
Quasars are enormous black holes that are surrounded by huge amounts of gas and dust, which makes them extremely bright, and definitely brighter compared to a typical galaxy.
The online publication mentioned above explains that Milky Way, for instance, is currently on a collision course with the Andromeda galaxy. The event will be occurring billions of years from now, and it will mark the end of two galaxies and the creation of a quasar.
After that, the gas and dust will be falling into the center of the quasar, and it will be blown into space. Astronomers have been speculating that this point will basically be the end of a galaxy’s life.
This will mark the moment in which the galaxy lost the ability to form new stars, and it just becomes “passive” as CNET puts it.
Cold quasars can still form new stars
What’s mindblowing is the fact that Kirkpatrick and her team have just found out that a small fraction of these cold quasars was still forming new stars.
“These galaxies are rare because they’re in a transition phase,” said Kirkpatrick in a press release.
She continued and said, “We’ve caught them right before star formation in the galaxy is quenched, and this transition period should be very short.”
It also seems that extremely high winds will be blowing through the galaxy, and this period would only last for about 10 million years. This is enormous to use, but in the universe’s timelines, it’s just the blink of an eye.
This is the ultimate fate of our galaxy.
