Astronomers from the University of Geneva, working with colleagues in Canada and the United States, have captured the ...

An international team of astronomers has discovered that helium atoms are causing the atmosphere of a "warm-Neptune" exoplanet to expand like a party balloon before escaping into the cold expanse of ...

Astronomers have discovered a distant planet with an abundance of helium in its atmosphere, which has swollen to resemble an inflated balloon. An international team of researchers, including Jessica ...

If you think global warming is bad, 11 billion years ago the entire universe underwent, well, universal warming. The consequence was that fierce blasts of radiation from voracious black holes stunted ...

Scientists using the Lyman Alpha Mapping Project (LAMP) aboard NASA's Lunar Reconnaissance Orbiter have made the first spectroscopic observations of the noble gas helium in the tenuous atmosphere ...

In 1930, Dorrit Hoffleit reported that star number #4749 in the Harvard List of variables had faded four times between 1897 and 1929, and identified it as an R Coronae Borealis (RCB) variable. RCB ...
