Astonomers measured the wavelength of the oxygen spectrum, which is stretched because the universe expands, to find out the size of time the oxygen has been there, the Orlando Sentinel reported.
“I feel this paper is essential,” Aparna Venkatesan, professor in physics and astronomy on the College of San Francisco, instructed Gizmodo.
She added that an excessive amount of shouldn’t be learn into the examine, nevertheless.
“I feel the one factor that’s a little bit unsure is the star formation historical past,” she instructed Gizmodo. She mentioned the researchers’ conclusions are however one interpretation of the info.
