Brief Answers to Cosmic Questions Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both? Evolution of the Universe Did the Universe expand from a point? Competition Grows For Orbital Solar Power Jun June 25, 2009 | 35 Comments PowerSat Corp. has filed a provisional patent for two technologies called BrightStar and Solar Power Orbital Transfer, that are expected make the transmission of space solar power more cost-effective by reducing the price for launch and operation of systems as large as 2,500 megawatts by about $1 billion.
Space Solar Power About Space Solar Power (SSP, also known as Space-Based Solar Power, or SBSP): The United States and the world need to find new sources of clean energy. Space Solar Power gathers energy from sunlight in space and transmits it wirelessly to Earth. Space solar power can solve our energy and greenhouse gas emissions problems. Not just help, not just take a step in the right direction, but solve.
Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! Power company plans first orbital solar power satellite - Boing Boing Pacific Gas and Electric is reportedly seeking permission to test a solar power satellite, which would send energy generated in orbit to a radio receiver station in Fresno County, California. the solar energy available in space is eight-to-ten times greater than on earth. There’s no atmospheric or cloud interference, no loss of sun at night, and no seasons.
s WMAP Science Team Awarded 2012 Gruber Cosmology Prize NASA's WMAP Science Team Awarded 2012 Gruber Cosmology Prize NASA's Wilkinson Microwave Anisotropy Probe, known as WMAP, transformed the science of cosmology by establishing the age, geometry, and contents of the universe to astonishing precision. On June 20, the Gruber Foundation recognized this accomplishment by awarding its 2012 Cosmology Prize to WMAP principal investigator Charles L. Bennett at Johns Hopkins University in Baltimore and the science team he led. Japan Plans $21 Billion Solar Space Post to Power 294,000 Homes The concept of space-based solar power was introduced way back in 1968, but it’s only recently that the world has latched on to the idea. Japan is definitely getting in on the action with its latest spacey plan – a $21 billion solar-powered generator in the heavens to produce one gigawatt of energy, or enough to power 294,000 homes. The Japanese government announced the plan back in June, but there has been an important new development – Mitsubishi Electric Corp. and industrial design company IHI Corp. are now teaming up in the race to develop new technology within four years that can beam electricity back to Earth without the use of cables. Mitsubishi and IHI are joining a research group containing 14 other countries to tackle the daunting task of getting Japan’s four square kilometer solar space station up and running in the next three decades.
NASA discovers portals (but don’t book your ticket yet) Madeleine L’Engle called them tesseracts. The Syfy channel calls them wormholes. Gamers call them portals. Space Future Journal - Space-based Solar Power by 2016? In 2009, Manhattan Beach, CA-based company Solaren, Inc. signed a contract with Pacific Gas & Electric (PG&E) to provide 200 megawatts (MW) of clean, reliable electrical power to customers at a rate comparable with existing power generation facilities. But unlike hydroelectric, coal, fossil fuel, and nuclear production, this power will come from that constant, inexhaustible source, the Sun. This is known as “Space Based Solar Power,” and until recently, it was also known as “science fiction.” But in the here and now, Solaren designers have developed a system involving multiple satellites to be delivered into geosynchronous orbit ( GEO
Mission to Mars meets reality TV The first people to colonize Mars might be reality TV show contestants. No, this is not a joke - it's a tremendously ambitious, eyebrow-raising plan devised by Dutch company Mars One. Next year, the company aims to select several teams of four astronauts each, and the public will be the final judge as to which team will get the ticket for a (one-way!) Some black holes may be older than time Stuart Gary for ABC Science Online Updated Fri 6 May 2011, 5:48pm AEST An intriguing new hypothesis suggests some black holes could have formed before the formation of our universe. The work by Professor Bernard Carr from Queen Mary University in London and Professor Alan Coley from Canada's Dalhousie University, examines a cosmology in which the universe goes through cycles of birth and death. According to their work published on the pre-press website arXiv.org, some black holes could be remnants of a previous universe that collapsed in a big crunch and was then reborn in the big bang - 13.7 billion years ago.
