The vast majority of these objects are galaxies containing massive black holes or rapidly growing new stars. Other discoveries include the collision of groups of distant galaxies and bright stars, which vary in brightness, in the Milky Way, according to a statement from the University of Durham in England.
The observations were made by analyzing a massive amount of data from the sensitive Low Frequency Array telescope, known as LOFAR, which uses low radio frequencies to observe and classify in detail about a quarter of the Northern Hemisphere sky. It is operated by ASTRON, the Netherlands Institute for Radio Astronomy.
Radio astronomy is another way to reveal the secrets of the universe, especially things that cannot be seen with visible light waves, such as black holes.
“Each time we create a map, our screens are filled with new discoveries and things that human eyes have never seen before. Exploring the unknown phenomena that shine in the world of active radio is an incredible experience and our team is delighted to be able to make these maps public,” said astronomer Timothy Shimwell. scientist participating in the ASTRON and Leiden University in a statement.
This version of the data Only 27% of the entire survey, Schmuel said.
“We hope this will lead to many scientific advances in the future, including the study of the growth of the largest structures in the universe, the formation and evolution of black holes, the physics that governs star formation in distant galaxies, and even details of the most exciting stages in the life of stars in our galaxy.
To map space objects, scientists used algorithms on high-performance computers across Europe to process 3,500 hours of observations. This computing feat required the computing power of nearly 20,000 laptops.
