Gamma-ray bursts shed light on the composition of the early galaxies Scientists prove

A team of astronomers studied the light from the gamma-ray bursts GRB 090323, to understand the chemical composition of the two galaxies, young universe. Observations made with the ESO VLT European Southern Observatory experts found that these galaxies are rich in heavier chemical elements than the sun.

The light from the flash GRB 090323 was a parent and a neighboring galaxy. Some colors are usually absorbed by the cold gas around galaxies, leaving a characteristic dark lines in the spectrum. Thanks to gamma-ray bursts GRB 090323, the
