Scientists are using photographs taken by astronauts aboard the International Space Station (ISS) to reliably measure the amount of light pollution worldwide and to produce a global colour map of the Earth at night. The total cost of the energy consumption for streetlights is estimated by the study to be 6300 million euros/year in the European Union.
Physicists are gearing up to send a re-engineered science instrument originally designed for lofty balloon flights high in Earth’s atmosphere to the International Space Station next week to broaden their knowledge of cosmic rays, subatomic particles traveling on intergalactic routes that could hold the key to unlocking mysteries about supernovas, black holes, pulsars and dark matter.
