Chaos theory approach reveals long-distance relationship in seemingly random behavior of bowhead whales
Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.

Are there any advanced alien civilizations elsewhere in our galaxy? We don't know. All we do know is that there is at least one. Should we be optimistic or pessimistic about finding others?
Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from black hole surroundings. The radiation originates from the combined effect of ...

An international team of astronomers reports the detection of a blazar with highly significant sinusoidal radio variability using the Owens Valley Radio Observatory (OVRO). The finding was detailed in a research paper published ...
Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0-722844. They detected an X-ray outburst from this binary and found that it harbors a white ...
Astronomers have performed photometric observations of a young globular cluster known as NGC 1851. The new observational campaign provides more insights into the variable star population of this cluster and validates the ...
Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called accretion disks surrounding black holes, using state-of-the-art supercomputers ...
