A new report concedes that much about the observed phenomena remains difficult to explain, including their acceleration, as well as ability to change direction and submerge.
he report determines that a vast majority of more than 120 incidents over the past two decades did not originate from any American military or other advanced U.S. government technology, the officials said. That determination would appear to eliminate the possibility that Navy pilots who reported seeing unexplained aircraft might have encountered programs the government meant to keep secret.
Extrema solstormar kan orsaka allvarliga störningar i samhället. Stora delar av Sveriges elförsörjning kan slås ut, och indirekt även mobilnätet. – Samhället blir allt mer sårbart för den här typen av händelser, säger rymdfysikern Urban Brändström.
1859 orsakade den så kallade Carrington-händelsen stora skador på dåtidens viktigaste kommunikationskanal; telegrafnätet. I både Europa och Nordamerika förstördes telegrafrullar och telegrafister fick el-stötar. Då såg man norrsken ända nere i Karibien.
1921 förstördes en telefonstation i Karlstad och ledde till omfattande problem med rikstelefonin.
1989 drabbades miljoner kanadensare av ett flera timmar långt strömavbrott
2003 blev tiotusentals personer i Malmö utan ström i knappt en timme efter en solstorm.
The man who presumably started the Space Race was born on September 7 in 1914. He was best known for his Rockoon project, which proved the existence of the radiation belt sorrounding our planet.
Using data from NASA's Fermi Gamma-ray Space Telescope, scientists have recently discovered a gigantic, mysterious structure in our galaxy. This feature looks like a pair of bubbles extending above and below our galaxy's center. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old.
The ISS is major accomplishment for NASA (US), ESA (Europe), JAXA (Japan) CSA (Canada) and all the countries involved (16 in all). The space station is just over 72 m long by 108 m wide and 20 m high
Natural Science is an international journal dedicated to the latest advancement of natural sciences. The goal of this journal is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in different areas of natural sciences. All manuscripts must be prepared in English, and are subject to a rigorous and fair peer-review process. Accepted papers will immediately appear online followed by printed hard copy.

GLAS (the Geoscience Laser Altimeter System) is the first laser-ranging (lidar) instrument for continuous global observations of Earth, which will make unique atmospheric observations as an important component of the ESE climate change program. GLAS is a facility instrument designed to measure ice-sheet topography and associated temporal changes, cloud and atmospheric properties.and give us information on the height and thickness of radiatively important cloud layers which is needed for accurate short term climate and weather prediction. In addition, operation of GLAS over land and water will provide along-track topography.
It draws on more than 12 terabytes of imagery from several orbiting and land-based telescopes. It downloads the images on demand and stitches them together to form an interactive, browsable universe.
