Astronomers have found a vast reservoir of hydrogen with something conspicuously missing: detectable starlight. The object, called AGC 322753, contains roughly 2 billion times the sun's mass in neutral hydrogen, a potential supply of material for making stars. Its radio signal su

Astronomers have found a vast reservoir of hydrogen with something conspicuously missing: detectable starlight. The object, called AGC 322753, contains roughly 2 billion times the sun's mass in neutral hydrogen, a potential supply of material for making stars. Its radio signal suggests the gas may be rotating in a disk, yet deep astronomical images reveal no matching glow.

Crows make decisions twice as fast as humans and monkeys

University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average to identify the direction in which a dot pattern was mov

Astronomers uncover a mysterious magnetic web above the Sun

The Sun’s seemingly peaceful regions are hiding a surprisingly complex magnetic world. Using a balloon-borne telescope high above Earth, scientists discovered delicate, thread-like magnetic structures woven through the solar atmosphere, apparently shaped by twisting motions on th
