Hidden New Galaxies, Discovered

The presence of billions of dust galaxies have been reportedly discovered by astronomers recently. The galaxies were apparently hidden in plain sight all this while.

A new study indicates that the glowing dust that can be seen at a distance during the night time sky is basically hiding far away galaxies, which could be seen in plain sight otherwise. The new theory was formed by scientists, who took the help of a statistical algorithm to analyze which galaxies would be able to light up the huge collections of hot gas, which can be seen in plain sight by observatories all over the globe.

The researchers now believe that this hidden discovery has led to a gross over estimation concerning the rates at which stars per galaxy are developing in the universe. "This is a really interesting result because when we assumed that one galaxy had to be responsible for all of that dust emission, it implied that the galaxy must be forming a tremendous number of new stars," said astrophysicist Jillian Scudder. "Forming that number of stars in a galaxy so early in the universe is quite hard to explain. By find that each galaxy is actually two or three galaxies, we've dropped the number of stars these galaxies have to be producing by a third. In simpler words, the enormous universe tucked away from our vision may have just become even more massive.

It was difficult for the researchers to arrive at the hidden in plain sight theory, primarily because of two limitations. First of all, there were issues with image resolution because the far infrared scans captured so far by the Herschel Space Observatory and other laboratories wrongly identified numerous hidden celestial objects as a single one. The other limitation was caused by miscalculations, as scientists had previously credited only the galaxy located nearest to the visible glowing dust as the cause of the occurrence.

Furthermore, according to the study, a single galaxy is possibly the only source of such a gas illumination when it can be directly seen in the center of the gassy image. The scientists also suggested that all the other glowing gas is because of far away galaxies that are hidden in plain sight, which have resulted in the radiation that is heating the apparently glowing gas. Moreover, as per the observation, the hidden discovery has led to the over estimation regarding the rates at which stars per galaxy are forming in the universe, and it might also explain how the bright galaxies got so bright in the first place.
