When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.

New research suggests that an effective way to locate and track large concentrations of microplastics in the ocean could be from high in the sky.

With thousands of satellites, each network could beam down tens of terabits per second, filling gaps left by land-based services.

Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.

Chances are small that space junk will destroy property or harm a person, and existing space law could deal with such an event. But current law doesn't address the bigger problem of space pollution.

Student-led efforts preserve iconic campus landmark for future generations of education and research.

Creating satellites that could travel flat and transform themselves into a dish shape would make space exploration easier, say researchers.
