A new map of the night sky is published and hundreds of thousands of undetected galaxies are on it. 300,000 new galaxies were discovered as part of a study involving 200 scientists from 18 low-frequency telescope (LOFAR) countries in the Netherlands.
The telescope can detect sources of light the optical instruments can not see. With the help of the device, scientists have been able to spot hundreds of thousands of light sources believed to be galaxies that were once too weak to be found on Earth. The discovery casts a new light – literally – on the universe.
"This is a new window for the universe," said Cyril Tase, an astronomer at the Paris Observatory who participated in the project. "When we saw the first images, we were like," What is this ?! "It did not look anything like what we are used to seeing." A series of articles about the findings are published in the Astronomy & Astrophysics journal
The LOFAR telescope works through traces or "jets" of the ancient radiation that occurs when galaxies merge These jets can stretch over millions of light years
"LOFAR has remarkable sensitivity, and this allows us to see that these jets are present in all the massive galaxies, which means their black holes never stop eating, " said Philippe Best, Professor of Extragalactic Astrophysics at Edinburgh University
Black holes have such a heavy gravitational pull that nobody can escape them. "The new observations will allow scientists to compare black holes with time to see how they are
Using information from the NASA space telescope scientists believe that there are more than 100 billion galaxies in the universe. However, many of them may be too old and too far to be observed through traditional detection techniques.
The LOFAR telescope, which consists of a network of radio antennas located in seven European countries, has helped scientists determine only 2 percent so far. The team plans to create high-resolution images of the entire northern sky, which they believe will reveal up to 15 million before undiscovered radio sources.
