SideWalk Astronomers Official website of the SideWalk Astonomers organisation, California, USA. Bringing astronomy to the public. http://www.sidewalkastronomers.us/
Extractions: Welcome to one of the official websites of our organization, which is dedicated to public service in astronomy. Since 1968, Sidewalk Astronomers' primary purpose has been to fill the need for public astronomical observation. More in the article "The Sidewalk Astronomers" Available are discussion forums on the subjects presented at this site, multimedia gallery with pictures and movies, and links to valuable related resources on the Internet. Also available are materials related to John Dobson. Co-founder of Sidewalk Astronomers and creator of the Dobsonian telescope mount. His scientific musings are very thought provoking and, like Einstein's Relativity, require us to re-examine many of our long-held views. Dobson's theories in physics and cosmology boldly break new ground and significantly challenge the scientific orthodoxy.

Extractions: news GALLERY DISCOVERIES FUN ... astrofile Background information Key Events in the History of Centaurus A 1847: Sir John Herschel was the first to report observations of what we now know as NGC 5128, or its radio name Centaurus A. In his "Outlines of Astronomy," published in 1849, Herschel described it as "two semi-ovals of elliptically formed nebula appearing to be cut asunder and separated by a broad obscure band parallel to the larger axis of the nebula, in the midst of which a faint streak of light parallel to the sides of the cut appears." 1848-1949: Despite Herschel's observation, astronomers paid little attention to Centaurus A for about 100 years because they considered it another one of those nebulous, fuzzy objects originally thought to be in our own galaxy. Even Edwin Hubble called it a nebulous object. Later astronomers with more powerful telescopes identified many of these objects as galaxies. Centaurus A also was largely ignored because of the lack of large optical telescopes in the southern hemisphere, where this galaxy can be seen. 1949: Astronomers had just developed another technique to study celestial objects besides optical light: special instruments to collect radio waves. Using an 80-foot radio antenna at Dover Heights, Australia and radio waves reflected off the nearby sea, astronomers John Bolton, G. Stanley, and Bruce Slee were the first to identify Centaurus A as a powerful radio galaxy. Radio waves from Centaurus A were among the first to be linked to an extragalactic object.

Extractions: The Vancouver Sidewalk Astronomers are a loosely knit group of amateur astronomers from the Vancouver / Portland area dedicated to sharing a view of the heavens with all who are interested. Typically a "Star Party" is scheduled and interested individuals are notified of the time and place. Frequently a telescope or other equipment is demonstrated for the budding astronomer. At times a general invitation to the public is advertised in "The Columbian" At a star party all interested are welcome to stop and take a peek through the telescopes. Occasionally astronomy classes are given with a star party following. Teachers are welcome to contact us regarding setting up star parties for individual classes. Star parties provide an excellent way to be introduced to astronomy. Unlike most sciences, the amateur can play a major role in astronomy. Most of the commercial or institutional telescopes have to be put to some very specialized uses in order to justify the cost of their existence. Many tasks of astronomy can only be accomplished by dedicated amateur astronomers equipped with small telescopes and simple equipment.
Extractions: NASA and G. Bacon/STScI Residing 7,200 light-years away, the planet weighs 2.5 times as much as Jupiter and formed when the universe was an infant, Steinn Sigurdsson of Pennsylvania State University in State College and his colleagues report in the July 11 Science The planet's very existence suggests that such orbs formed relatively soon after the Big Bang. Moreover, the object's locationnear the crowded core of a star cluster, where planetary systems might easily be ripped apartindicates that planets might be more abundant than thought. The planet lies near the center of the globular cluster M4, a dense grouping of stars about 12.5 billion years old. Old stars such as these are metal poor because they formed before subsequent generations of stars had produced heavy elements in abundance. Astronomers have found most extrasolar planets orbiting younger, relatively metal-rich stars. That led astronomers to rate ancient globular clusters as unlikely venues for planets. Indeed, in a 1999 study looking for planets that closely orbit stars in the globular cluster 47 Tucanae, the Hubble Space Telescope failed to find a single one.
Important Astronomers, Their Instruments And Discoveries 1 Alexandrian astronomers Aristillus and Timocharis charted the positions of the brighter stars (284 BC), producing the first star catalog using a Crossstaff http://obs.nineplanets.org/psc/hist1.html
Extractions: Important Astronomers, their Instruments and Discoveries by Paul M. Rybski Part 1 Pre-telescopic Instruments, their Inventors and Users Babylonian observations (1500 BC?) recorded solar and lunar eclipses as well as planetary observations using merkets and waterclocks. Macedonian philosopher Thales of Miletus (575-532 BC?) predicted a solar eclipse using Babylonian observations and mapped out constellations to aid navigation. Alexandrian astronomer Eratosthenes (260-201 BC?) measured the circumference of the Earth using comparative shadow rod measurements in two places and knowledge of the distance between them. Alexandrian astronomers Aristillus and Timocharis charted the positions of the brighter stars (284 BC), producing the first star catalog using a Cross-staff. Aristarchus of Samos (250 BC?) calculated the distance of the Sun from the Earth and the Moon and Sun's sizes relative to Earth by observations during solar and lunar eclipses and at first quarter Moon using a Cross-staff. Eratosthenes (204 BC) catalogued more than seven hundred stars using one, and possibly two, armillary spheres.
