Astronomers accidentally discovered the footprints of a monster galaxy in the early universe that has never been seen before.
About:
Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given the lack of evidence of their existence, but astronomers in the United States and Australia managed to snap a picture of the beast for the first time.
Published in the Astrophysical Journal, the discovery provides new insights into the first growing steps of some of the biggest galaxies in the universe.
The researchers estimate that the signal came from so far away that it took 12.5 billion years to reach Earth, therefore giving us a view of the universe in its infancy.
They think the observed emission is caused by the warm glow of dust particles heated by stars forming deep inside a young galaxy. The giant clouds of dust conceal the light of the stars themselves, rendering the galaxy completely invisible.
