Radio Solar Telescope Network
{{unreferenced, date=August 2013 The Radio Solar Telescope Network (RSTN) is a network of solar observatories maintained and operated by the 557th Weather Wing, ACC. The RSTN consists of ground-based observatories in Australia, Italy, Massachusetts, and Hawaii. History It became apparent in the early 1960s that certain space weather events might interfere with the stated U.S. objective of a crewed mission to the moon. In particular, the sun emits continuous electromagnetic energy and electrically charged particles, which can cause disturbances in the near-Earth environment and disrupt satellite communications. Foremost among these concerns was the possibility of a geomagnetic storm of solar origin. Metric Type II radio bursts, signatures of coronal shock waves or coronal mass ejections, were known to be commonly associated with solar flares. The United States Air Force Research Laboratory (AFRL) was thus assigned the task of developing and validating a network of ground-based so ...

Ionospheric Prediction Service
The ionosphere () is the ionized part of the upper atmosphere of Earth, from about to above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth. History of discovery As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field. Sixty years later, Guglielmo Marconi received the first trans-Atlantic radio signal on December 12, 1901, in St. John's, Newfoundland (now in Canada) using a kite-supported antenna for reception. The transmitting station in Poldhu, Cornwall, used a spark-gap transmitter to produce a signal with a frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaena Point
Kaena or Kaena Point is the westernmost tip of land on the island of Oahu. In Hawaiian, ''kaena'' means 'the heat'. The area was named after a brother or cousin of Pele. The point is designated as a Natural Area Reserve. Some ancient Hawaiian folklore states that Kaena Point is the "jumping-off" point for souls leaving this world. History In Hawaiian, ''kaena'' means 'the heat'. The area was named after a brother or cousin of Pele who accompanied her from ''Kahiki''. The State of Hawaii has designated the point as a Natural Area Reserve to protect nesting Laysan Albatrosses and wedge-tailed Shearwaters, Hawaiian monk seals, and the fragile (to vehicular traffic) native strand vegetation that has been restored there. Some ancient Hawaiian folklore states that Kaena Point is the "jumping-off" point for souls leaving this world. In 1899, the Oahu Railway and Land Company constructed a railway that encompassed 70 miles from Honolulu through Kahuku to transport sugarcane. Mos ...

Hamilton, Massachusetts
Hamilton is a town in the eastern central portion of Essex County in eastern Massachusetts, United States. At the 2020 census, it had a population of 7,561. Currently the town has no manufacturing industry and no industrially-zoned land. Though Hamilton is a landlocked town in the North Shore region of Massachusetts, its proximity to it provides easy access to the Atlantic seashore with its reservations, beaches and boating. The town includes many historic houses, pastoral landscapes, and old stone walls that accompany winding tree-lined roads. It also has a rich equestrian heritage, which remains strong due to the influence of the many horse farms and of Myopia Hunt Club, which holds frequent equestrian events, including polo most Sunday afternoons. (Myopia also hosts a Thanksgiving Day fox hunt each year that the public may attend.) Thus, people visiting Hamilton may well share the secondary roads with horse and pony riders.
