Aboard the ISS, researchers investigate complex dust behavior in plasmas

more »
Four hundred kilometers above Earth, researchers examined waves in complex plasma under microgravity conditions and found that the microparticles behaved in nonuniform ways in the presence of varying electrical fields. They report some of the first findings from the Plasma-Kristall 4 (PK-4) experiment in a new paper.

Largest haul of extrasolar planets

more »
Forty-four planets in planetary systems beyond our own have been unveiled in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less. The findings will improve our models of planetary systems and may help researchers investigate exoplanet atmospheres. Novel techniques developed to validate the find could hugely accelerate the confirmation of more extrasolar planet candidates.

Million fold increase in the power of waves near Jupiter's moon Ganymede

more »
Chorus waves are electromagnetic waves. Converted to sound they sound like singing and chirping birds at dawn. They can cause polar lights above the Earth as well as damage to satellites. Now, a team of researchers has found that such waves are intensified million-fold around Jupiter's moon Ganymede. This study provides important observational constraints for theoretical studies.
