Aliens could send quantum messages to Earth, calculations suggest

An intelligent alien civilization could beam quantum messages to Earth. Particles of light, or photons, could be transmitted over vast, interstellar distances without losing their quantum nature, researchers report June…

An otherwise quiet galaxy in the early universe is spewing star stuff

PASADENA, Calif. — A lucky celestial alignment has given astronomers a rare look at a galaxy in the early universe that is seeding its surroundings with the elements needed to…

Gravitational wave ‘radar’ could help map the invisible universe

It sounds like the setup for a joke: If radio waves give you radar and sound gives you sonar, what do gravitational waves get you? The answer might be “GRADAR”…

Seven newfound dwarf galaxies sit on just one side of a larger galaxy

PASADENA, Calif. — The faint dwarf galaxies in a nearby galaxy group seem to have missed the memo. Instead of being dispersed evenly around the group’s most massive galaxy, which…
