A nearby planet could form a ring of gas around its star, revealing unique signatures in its light that can be observed today ...

A complementary approach is to swap the helium gas for liquid helium, which has a much higher density. Sótér and colleagues found that this method could be used to measure very narrow lines in the ...

For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...

Astronomers use AI to classify white dwarfs and uncover rare stars with shifting surfaces and unusual chemistry.

IN a recent communication Deeming and Walker 1 have found that for hot stars there is a significant positive correlation between their helium line strengths and their apparent rotational velocities.

What on Earth does a gas that we normally associate with balloons have to do with Guntur, a city in Andhra Pradesh? Everything, apparently! Though, to be absolutely clear, it must be stated that it ...

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using ...

Scientists in the European collaboration PAMELA say they have evidence that challenges the current theory of how cosmic rays are accelerated through the universe. According to the team, the spectra of ...
