The first stars may not have been as uniformly massive as astronomers thought

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of stars to form the first ...

Rapid-response protocol promises to reveal supernovae only hours after they explode

Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion ...

Unlocking the sun's secret messengers: DUNE experiment set to reveal new details about solar neutrinos

Neutrinos—ghostly particles that rarely interact with normal matter—are the sun's secret messengers. These particles are born deep within the sun, a byproduct of the nuclear fusion process which powers all stars.

Experimental device demonstrates how electron beams reconfigure plasma structure

In a scientific first, South Korean scientists have provided experimental proof of "multi-scale coupling" in plasma, where interactions between phenomena at the microscopic level and macroscopic level influence each other. ...
