While NASA previously determined that over there were around two trillion galaxies in the universe, brand-new findings say the number is more likely numerous billions.

The external world, or universe in this case, just acquired a little clearer. Scientists newly took a deep dive into some unexplained sightings out in the solar system, and also their findings need to do with whatever from the actual variety of galaxies in the world to the species of stars around us. Back in April 2020, NASA very first detected a huge flare indigenous its satellites the passed through Mars, and while this intergalactic sighting lasted because that a only 140 milliseconds, a research study team in college of Johannesburg now knows that this was a burst from a magnetar, which is a an effective neutron star v a magnetic field. It originated in a galaxy 11.4 million light-years away in space, the Daily Mail reports.
Soebur Razzaque, a professor indigenous the university of Johannesburg, noted that this sighting isn't also unlikely since there are tens of thousands of neutron stars in the Milky Way, yet there room still simply 30 that have been uncovered together magnetars. "Magnetars room up come a thousand times more magnetic than ordinary neutron stars," he explained. "Most emit X-rays every now and then. However so far, we recognize of just a grasp of magnetars that created giant flares. The brightest we might detect was in 2004." there is a opportunity that if another is spotted close come the Milky Way, that a radio telescope, prefer the MeerKAT in southern Africa, researchers have the right to learn even much more about the inner functions of few of the most powerful forces in space. "That would certainly be wonderful opportunity to study the partnership between an extremely high power gamma-ray emissions and radio tide emissions in the 2nd explosion," Razzaque adds. "And that would certainly tell us more about what works and also doesn't job-related in our model."

When it concerns outer room as a whole, researchers have been busy discovering more than simply stars. A brand-new study in the Astrophysical Journal uncovered that over there actually could be fewer galaxies than previously thought; these findings stemmed indigenous the team measure the weak elevator glow native unseen galaxies, according to the Daily Mail. "It's vital number come know—how plenty of galaxies are there? We just don't see the irradiate from 2 trillion galaxies," mark Postman, a researcher indigenous the an are Telescope science Institute and a lead writer of the study, said.
After doing much more research, the team found that NASA's new Horizon spacecraft just detected numerous billions that galaxies instead of two trillion. Estimates before were uncovered from NASA's Hubble room Telescope, however the Hubble largely uses mathematical models to uncover galaxies as result of the telescope's i can not qualify to see sufficient in clearly shows light since of room pollution. There will still be a follow-up examine to check these findings, though: "NASA's upcoming James Webb space Telescope might be maybe to aid solve the mystery," the team common in a statement. "If faint, separation, personal, instance galaxies room the cause, climate Webb ultra-deep ar observations should be able to detect them."
