Producing electricity at estuaries using light and osmosis

Most renewable power technologies are weather dependent. Wind farms can only operate when there's a breeze, and solar power plants rely on sunlight. Researchers at EPFL are working on a method to capture an energy source ...

Water formation on the moon

For the first time, a cross-disciplinary study has shown chemical, physical, and material evidence for water formation on the moon. Two teams from the University of Hawaiʻi at Mānoa collaborated on the project: physical ...

Dynamic energy management system for SMBs

Solar power, wind power and the lot – the growing use of renewable energy sources is resulting in substantial fluctuations in energy production. Fraunhofer researchers have now made it possible to design industrial processes ...

NASA launches two rockets studying auroras

NASA successfully launched the Auroral Zone Upwelling Rocket Experiment or AZURE mission on April 5 from the Andøya Space Center in Norway.

Jupiter's atmosphere heats up under solar wind

New Earth-based telescope observations show that auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought—and that it is a rapid response to the solar wind.

And the blobs just keep on coming

When Simone Di Matteo first saw the patterns in his data, it seemed too good to be true. "It's too perfect!" Di Matteo, a space physics Ph.D. student at the University of L'Aquila in Italy, recalled thinking. "It can't be ...

Solar wind

The solar wind is a stream of charged particles—a plasma—ejected from the upper atmosphere of the sun. It consists mostly of electrons and protons with energies of about 1 keV. The stream of particles varies in temperature and speed with the passage of time. These particles are able to escape the sun's gravity, in part because of the high temperature of the corona, but also because of high kinetic energy that particles gain through a process that is not well-understood.

The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae such as the Northern Lights, and the plasma tails of comets that always point away from the sun.
