By analyzing the data from the Far Ultraviolet Spectroscopic Explorer (FUSE) telescope, an international team of astronomers has discovered cesium in the atmosphere of a hot white dwarf known as HD 149499B. The finding, reported ...
An international team of physicists has developed a new technique that allows researchers to study the interactions between neutrons inside of an atom. In their paper published in the journal Nature, the group describe their ...
It has long been theorized that hydrogen, helium, and lithium were the only chemical elements in existence during the Big Bang when the universe formed, and that supernova explosions, stars exploding at the end of their lifetime, ...
