Scientists say that there are likely fewer galaxies in space than they previously thought
While NASA previously determined that there are about two trillion galaxies in the universe, the new results indicate that the number is in the hundreds of billions.
Outside world, Or the universe in this case, is becoming more and more clear. Scientists recently took a deep dive into some unusual observations in the solar system, and their findings relate to everything from the actual number of galaxies in the universe to the types of stars around us. Back in April 2020, NASA It first detected an enormous glow from its satellites that passed by Mars, and while this vision between galaxies lasted for only 140 milliseconds, my research team did University of Johannesburg It is now known that this was a blast from a magnetic star, which is a powerful neutron star with a magnetic field. It arose in a galaxy 11.4 million light years away in space daily Mail Reports.
Soebur Razzaque, a professor at the University of Johannesburg, noted that such a vision is not far-fetched given that there are tens of thousands of neutron stars in the Milky Way, but there are still only 30 that have been discovered as magnetic stars. He explained that „magnetic stars are magnetic up to a thousand times more than normal neutron stars.“ „Most x-rays emit from time to time. But until now, we only know a few magnetic stars that produced giant glows. It was the brightest star that we were able to discover in 2004.“ There is a chance if Another was spotted Close to the Milky Way, radio telescope researchers, like MeerKAT in South Africa, could learn about the inner workings of some of the most powerful forces in space. „This will be an excellent opportunity to study the relationship between high-energy gamma-ray emissions and radio-wave emissions in the second explosion,“ Razaki adds. „This should tell us more about what works and what does not work in our model.“

When it comes to Outer space as a whole, Researchers have been busy discovering more than just stars. A new study in The Astrophysical Journal Found that there may actually be fewer galaxies than previously thought; These results originated from the team that measured weak background glow from unseen galaxies, according to daily Mail. „It’s an important number to know – how many galaxies are there? We simply don’t see the light from two trillion galaxies,“ Mark Postman, researcher at Space Telescope Science Institute The lead author of the study said.
After doing more research, the team found that NASA’s New Horizons spacecraft had discovered only hundreds Billions of galaxies Instead of two trillion. Estimates have been found before from NASA’s Hubble Space Telescope, but Hubble mainly uses mathematical models to discover galaxies due to the telescope’s inability to see enough in visible light due to space pollution. There will still be a follow-up study to confirm these findings, although: „The upcoming James Webb Space Telescope from NASA may be able to help solve the mystery,“ the team also shared in a statement. „If faint single galaxies are the cause, then super-deep web observations should be able to detect it.“
