Scientists say that there are fewer galaxies in space than previously thought
While NASA previously determined that there are about two trillion galaxies in the universe, new findings say that number is likely in the billions.
The outer world, or the universe, in this case, became a little clearer. Scientists recently took a deep dive to see some unusual scenes 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. In April 2020, NASA first detected a huge flare from its satellites that passed through Mars, and while this international vision lasted only 140 milliseconds, a research team at the University of Johannesburg now knows it was a magnetar explosion. , Which is a powerful neutron star with a magnetic field. It originated in a galaxy 11.4 million light years away in space Rajinda message Reports.
Sobur Razzak, a professor at the University of Johannesburg, noted that this galaxy is unlikely to be visible because of the thousands of neutron stars in the galaxy, but there are still only 30 that have been revealed as magnets. “Magnetars are a thousand times more magnetic than ordinary neutron stars,” he explained. “Most of the time X-rays emit. But so far, we only know about a few magnets that produced huge flares. The brightest we could find was in 2004.” It is likely that if one looks closely at the Milky Way galaxy, like South Africa’s Mercury, radio telescopes, researchers can learn more about the inner workings of some of the most powerful forces in space. “The second explosion would be the best opportunity to study the relationship between very high energy radiation gamma-ray emissions and radio wave emissions,” Razzak adds. “And it will tell us more about what works and what doesn’t in our model.”

When it comes to the entire outer space, researchers are busy discovering more than just stars. A new study in the Astrophysical Journal has found that there may actually be fewer galaxies than previously thought; These findings arose from a team measuring weak background glow from unseen galaxies Rajinda message. “It’s important to know how many galaxies there are,” said Mark Postman, a researcher at the Space Telescope Science Institute and lead author of the study. We don’t just see the light of two trillion galaxies. ‘
After further research, the team discovered that NASA’s New Horizon spacecraft discovered hundreds of billions of galaxies instead of just two trillion. Previous estimates were made from NASA’s Hubble Space Telescope, but Hubble mainly uses mathematical models due to the inability of the telescope to see the adequacy of visible light due to space pollution. There will be one more follow-up study to confirm these findings, however: “NASA’s upcoming James Webb Space Telescope could help solve the mystery,” the team shared in a statement. “If obscure, individual galaxies are the cause, then web ultra-deep field observations should be able to detect them.”
