All good things are coming to an end, even in the Milky Way. It is not estimated that our home galaxy end mise will occur over at least 400 million or 5 billion years when astronomers believe they will clash with their neighbor Andromeda. But a New analysis The more distant galaxies hint at another dramatic outcome. Milkyway’s universe destruction can begin from within instead of disappearing if it does not exist.
A chaotic, energy-spinned spiral galaxy
The Spiral Galaxy 2Masx J23453268-0449256 is located about a billion light years from Earth, and is measured approximately three times the size of the Milky Way. Like our own galaxy, there are super-large black holes lurking in their centers. However, our Sagittarius A (SGR A*) currently exists in a very cosmic, quiet dormant state (black hole), but the inside of J23453268-0449256 is confusing and expels a six million light-year energy jet jet. This is what international teams discovered using data collected by Hubble Space Telescope, a giant Metrulave radio telescope, a large millimeter wave array in Atacama, and multi-wave analysis.
According to their investigation published in the journal on March 20th Monthly Notices from the Royal Astronomical Societythese findings challenge traditional concepts of how galaxies work and what forces they can unleash.
Simply put, experts previously believed that galaxies like J23453268-0449256 could not survive under their own conditions. Roiling gamma, cosmics, and x-rays that arrive from black holes are only seen in elliptical galaxies. Based on traditional theory, these powerful radio jets need to confound the relatively delicate structure of the Spiral Galaxy. However, this is not the case at all for J23453268-0449256. The galaxy is fairly stable, with well-defined spiral arms, trouble-free stellar rings and bright nuclear bars.
“This discovery is not merely strange. It forces us to rethink the evolution of galaxies and how ultra-advanced black holes grow and shape the environment.” said in a statement.
One difference appears to be its ability to form new stars. Galaxies are surrounded by halos of X-ray exhaust gas needed to make them, but the super-large black hole energy jets act like deep space ovens. This appears to prevent the halo from cooling sufficiently to form a new star. Despite this stellar anomaly, J23453268-0449256 already hosts a huge number of stars.
“If spiral galaxies can not only survive, but also thrive under such extreme conditions, what does this mean for the future of galaxies like our own Milky Way?” I wonder Baguch.
How our own galaxies handle it
This type of scenario can be started when the Milky Way black hole SGR A* starts by devouring stars, gas clouds, and even small dwarf galaxies. These tidal cramtion events (TDEs) previously recorded in other galaxies are as dramatic as the powerful ones. However, depending on the direction, there are scenarios in which future lives on Earth do not survive the experience.
When the hypothetical Milky Way TDE cosmic rays line up in the solar system, their effects cause almost incomprehensible devastation. The energy beam can strip away the planet’s atmosphere, irradiate DNA enough to cause genetic mutations, destroy Earth’s ozone and kick off mass extinctions at dinosaur levels. Astronomers believe that Milkyway has hosted such kinds of radio jets in the past, but the chances that it will happen anytime soon are pretty slim.
Regardless of the ultimate celestial fate of the Milky Way, astronomers can learn more about the incredible and complex universe by discovering and studying unique adjacent galaxies like J23453268-0449256.
“Understanding these rare galaxies could provide important clues about the invisible forces that govern the universe, such as the nature of dark matter, the long-term fate of the galaxy, and the origin of life.” The study co-author said Shankar Ray, a doctoral candidate. “In the end, this research brings us one step closer to solving the mystery of the Cosmos and reminds us that the universe holds surprise beyond our imagination.”
