How many galaxies in the universe? This question has always been the main concern of astronomers around the world: several years ago, this number was estimated at about $ 2 trillion, but it seems that this number is preparing to increase considerably.
An international team of more than 200 astronomers from 18 different countries – with unprecedented accuracy – has detected more than 300,000 possible new galaxies by examining only a tiny portion of the night sky.
Precision is unparalleled
The research team used a new radio telescope system called the Low-Frequency Matrix (LOFAR), a telescope made up of a vast radio network of high-speed fiber optic antennas covering seven countries. So we have a radio telescope. 1900 km.
Radio telescopes are those that capture the signals of stars in the radio band.
The radio telescope consists of a very large antenna or antenna that can pick up frequencies from the depths of the universe. The higher the diameter of the radio telescope, the more precise it is. .
The new discoveries were published in 26 studies published in a special issue of the journal Astronomy and Astrophysics.
But it is highly likely that 20% of the night sky survey in the north of the country will be completed and only 10% of the data will be available to scientists, which means that a very large number of discoveries are pending.

Loafar should help capture the fine radiation of surrounding black holes while taking care of the surrounding matter, which can help develop the ability of astronomers to understand the nature of these holes and their origins.
For its part, Loafer gives strong indications of the existence of a magnetic field between galaxies, which will help to detect the mechanisms of formation and evolution of galaxies over time and their relations with each other within Hungarian communities.
The researchers hope that this set of studies will offer an entirely new opportunity to see the sky like never before, especially as the team seeks to provide high-resolution images of the entire sky north, revealing a total of nearly 15 million radio sources likely to be galaxies or black holes.
The researchers predict that this will lead to unique discoveries, including the first massive black holes formed when the universe was a "child," according to Hoop Rotering's global magazine of the University of Leiden in the Netherlands, that we could call a revolution of astronomy.
