Scientists Have Just Discovered 300,000 New Galaxies





Did you know that there are thousands of undiscovered galaxies? This is revealed by a global team of astronomers who published a significant new radio sky survey.

These previously undiscovered galaxies were discovered using the Low Frequency Array (LOFAR) telescope, with 300,000 newly revealed light sources believed to be emitting from faraway galaxies.

The LOFAR telescope, which is based in the Netherlands, is capable of detecting light source beyond the power of optical instruments, with radio astronomy allowing astronomers to detect radiation produced by the interaction of colossal celestial objects.

Over 200 scientists from 18 different countries collectively partook in this inspiring study, using radio astronomy to analyse a section of sky above the northern hemisphere. The radio signals in question are said to have travelled billions of light years before reaching Earth.

 “With radio observations we can detect radiation from the tenuous medium that exists between galaxies. This radiation is generated by energetic shocks and turbulence.”

These were the words of Amanda Wilber from Germany’s University of Hamburg during the press release from the Netherlands Institute for Radio Astronomy.

In addition, Annalisa Bonafede, from Italy’s University of Bologna stated:

“What we are beginning to see with LOFAR is that, in some cases, cluster of galaxies that are not merging can also show this emission, though at a very low level that was previously undetectable. This discovery tells us that besides merger events, there are other phenomena that can trigger particle acceleration over huge scales.”

These findings, as believed, will help shed light on different research areas, including the physics of black holes as well as the research into how galaxy clusters evolve.



Cyril Tasse, an Astronomer from the Paris Observatory told AFP:

“This is a new window on the universe. When we saw the first images we were like: ‘what is this?!’ It didn’t look anything at all like what we are used to seeing.”



 The universe is vast, but it is actually infinite; and it has more in it that definitely amaze us.
