We know that the universe is big, but it seems like researchers reassure us once again that it is huge. A recent discovery has taken scientists by surprise, as there are at least ten times more galaxies in the universe than initially believed. The discovery was possible thanks to the Hubble Space Telescope.
Researchers at the University of Nottingham received the support of the Royal Astronomical Society for their study. The new findings suggest that there could be more than two trillion galaxies in the universe. This new number is ten times bigger than previous estimations from the scientists.
Moreover, the scientists explain that the universe has much more secrets than we might have thought. They state that approximately ninety percent of the galaxies out there are unknown to us because we can’t see them. They are both hidden and distant, the scientists added.
The new study from researchers suggests that there are ten to twenty times more galaxies than previously thought. Other research pointed out that the number could be estimated to roughly one or two hundred billion galaxies, but the recent study shows that this is only a guess.
Scientists at the University of Nottingham started their research fifteen years ago. It was not easy for them to reach the stated conclusions. They used information not only from the Hubble Space Telescope but from other devices around the world too.
The process of discovering the number of galaxies in the universe required in-depth analyses and a series of algorithms and mathematical calculations. The researchers also used 3D models of the sky maps. They drew a comparison between the historical stages of the universe.
The specialists in charge of the new study observed that additional galaxies have formed across the millennia. Their research accounts for both big and small galaxies. They explain that the study was time-consuming because some of them are small, fainted and distant. These features make them hard to spot.
The recent research also provides scientists with new insight into the evolution of galaxies. As some form, others might disappear by fusing with already existing galaxies. It is usually small ones that attach to big ones. This phenomenon also makes the task of tracking and monitoring galaxies a bit more difficult.
The findings of the scientists at the University of Nottingham were published in Astrophysical Journal.
