Astronomers have long held that water—two hydrogen atoms and an oxygen atom—was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and ...

(Phys.org) —Theoretical astrophysicist Abraham Loeb of Harvard University has uploaded a paper he's written to the preprint server arXiv, in which he suggests that conditions shortly after the Big Bang may have been just ...
Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. The new results predict the maximum bandwidth of the ...

(Phys.org) —Physicists Lawrence Krauss and Frank Wilczek of Arizona State University and Australian National University, respectively, have uploaded a paper to the preprint server arXiv, in which they propose that it might ...
Scientists have used the tiny distortions imprinted on the cosmic microwave background by the gravity of matter throughout the universe, recorded by ESA's Planck satellite, to uncover the connection between the luminosity ...
