The big news in physics last week was the discovery of a faint line of gas elements in x-ray data that came from studying the space between galaxies—it didn't correspond to any known element. The team believes it's possible ...
What do tiny specks of silicon carbide stardust, found in meteorites and older than the solar system, have in common with pairs of aging stars prone to eruptions?
