A map created by astronomers shows at least 4.4 million space objects, most of them galaxies. But among them are 1 million space objects unseen so far. Even astronomers have been amazed at the "movements" in the universe. 

In this map, probably one of the most comprehensive maps, astronomers have discovered burning stars, colliding galaxies, huge black holes in galaxies, and many other spectacular objects and phenomena. As expected, in most galaxies, astronomers have observed a lot of stars forming, but also many dying, some resulting in black holes. 

The map was created using data collected by the Low Frequency Array (LOFAR) sensitive telescope belonging to the Dutch Institute for Radio Astronomy (ASTRON). This telescope is a little more special than others because it uses low radio frequencies, so observing only a quarter of the northern hemisphere sky, but observing a lot of detail focusing on that side. 

The telescope has been used in the past, of course, to gather data to help the scientific world take important steps in discovering the universe. And the data taken by astronomers and astrophysicists belongs to lot 2 of the LOFAR survey (which is made public). This "new batch" is quite large, covering data from an area 13 times larger than the first batch. There are millions of data in this lot 2, if only in the first one 300,000 data were collected. 

In total, there were 3,500 hours of observations (in lot 2), all processed by scientists using advanced algorithms from all over Europe. And to give you an idea of ​​what this meant, it can be equated with computing power of approx. 20,000 laptops.  

"Each time we create a map our screens are filled with new discoveries and objects that have never before been seen by human eyes. Exploring the unfamiliar phenomena that glow in the energetic radio universe is such an incredible experience and our team is thrilled to be able to release these maps publicly," said astronomer Timothy Shimwell,an associate scientist atASTRON and Leiden University.

"We anticipate it will lead to many more scientific breakthroughs in the future, including examining how the largest structures in the universe grow, how black holes form and evolve, the physics governing the formation of stars in distant galaxies and even detailing the most spectacular phases in the life of stars in our own Galaxy," he also said.

Shimwell also said that this release of data accounted for only 27% of the entire survey, according to CNN.
