Galactic trio might help astronomers uncover mysteries about the early universe
Fewed by - Muzammil Zafar
A research team led by James Rhoads, an astrophysicist at NASA's Goddard Space Flight Center, studied a trio of galaxies in the northern sky which are so are away that the light reaching Earth from them is only 680 million years old. Observation of the ancient galaxies has uncovered new evidence for why the early universe's hydrogen underwent ionization: it was due to the galaxies' high energy UV radiation.
