  • SOHO EIT 304 Latest Image

    The Sun Now– EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. In those taken at 171 Angstrom, at 1 million degrees. 195 Angstrom images correspond to…

  • Solar Dynamics Observatory

    SpaceCraft The total mass of SDO at launch was 3000 kg (6620 lb); instruments 300 kg (660 lb), spacecraft 1300 kg (2870 lb), and fuel 1400 kg (3090 lb). Its overall length along the sun-pointing axis is 4.5 m, and each side is 2.22 m. The span of the extended solar panels is 6.25 m.…

  • Poincaré Hyperbolic Disk

    See also:Poincaré Hyperbolic Disk *** Hyperbolic Geometry Geometric models of hyperbolic geometry include the Klein-Beltrami model, which consists of an open disk in the Euclidean plane whose open chords correspond to hyperbolic lines. A two-dimensional model is the Poincaré hyperbolic disk. Weisstein, Eric W. “Hyperbolic Geometry.” From MathWorld–A Wolfram Web Resource. http://mathworld.wolfram.com/HyperbolicGeometry.html   *** A…

  • Thoughts on Angel and Demons Plot

    “For me, the most attractive way … would be to capture the antihydrogen in a neutral particle trap … The objective would be to then study the properties of a small number of [antihydrogen] atoms confined in the neutral trap for a long time.“Gerald Gabrielse, 1986 Erice Lecture (shortly after first trapping of antiprotons)“Penning Traps,…

  • ta kymatika

    ……in Greek means “matters pertaining to waves.” Or in Hans Jenny’s case Cymatics. There were other images which mirrored biological forms and natural processes, as well as flowers, mandalas and intricate geometric designs – all this the result of audible vibration. These experiments seemed to reveal the hidden nature of creation, to lay bare the…

  • Fear and Ignorance

    This is a very significant physical result because it tells us that the energy of a system described by a harmonic oscillator potential cannot have zero energy. Physical systems such as atoms in a solid lattice or in polyatomic molecules in a gas cannot have zero energy even at absolute zero temperature. The energy of…

  • Space Weather

    Unfurling Prominence Eruption (October 10, 2008) The STEREO (Ahead) spacecraft observed this visually stunning prominence eruption on Sept. 29, 2008 in the 304 Angstrom wavelength of extreme UV light. It rose up and cascaded to the right over several hours, appearing something like a flag unfurling, as it broke apart and headed into space. The…

  • Galactic Neutrino Communications

    Galactic Neutrino Communication by John G. Learned, Sandip Pakvasa, A. Zee We examine the possibility to employ neutrinos to communicate within the galaxy. We discuss various issues associated with transmission and reception, and suggest that the resonant neutrino energy near 6.3 PeV may be most appropriate. In one scheme we propose to make Z^o particles…

  • Beyond the Dance of the Sun

    When we first start facing truth, the process may be frightening, and many people run back to their old lives. But if you continue to seek truth, you will eventually be able to handle it better. In fact, you want more! It’s true that many people around you now may think you are weird or…

  • SOHO Reads the Solar Flares

    Measurements of the Sun’s oscillations provide a window into the invisible interior of the Sun allowing scientists to infer the structure and composition as well as the rotation and dynamics of the solar interior. (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the…
