Boost to renewable energy by collecting solar power in space

solar power satellites

Solar power gathered in space could be set to provide the renewable energy of the future thanks to innovative research being carried out by engineers at the University of Strathclyde, Glasgow. Researchers at the University have already tested equipment in space that would provide a platform for solar panels to collect the energy and allow it to be transferred back to earth through microwaves or lasers. This unique development would provide a reliable source of power and could allow valuable energy to … Continue reading

Baby galaxies grew up quickly

Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute. This means that already in the early history of the Universe, there was potential for planet formation and life. The research results have been published in the scientific journal, Monthly Notices of the Royal Astronomical Society Letters. For several thousand years after the Big Bang 13.7 billion years ago, the Universe consisted of a hot, … Continue reading
