” Explanation: If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun’s position change? With great planning and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year is called an analemma. Yesterday, the Winter Solstice day in Earth’s northern hemisphere, the Sun appeared at the bottom of the analemma. Analemmas created from different latitudes would appear at least slightly different, as well as analemmas created at a different time each day. With even greater planning and effort, the series can include a total eclipse of the Sun as one of the images. Pictured is such a total solar eclipse analemma or Tutulemma – a term coined by the photographers based on the Turkish word for eclipse. The above composite image sequence was recorded from Turkey starting in 2005. The base image for the sequence is from the total phase of a solar eclipse as viewed from Side, Turkey on 2006 March 29. Venus was also visible during totality, toward the lower right.”
” South Korea has unveiled designs for its planned Moon lander, a key part of President Park Geun-hye’s pledge to revitalize the country’s aerospace industry and space programme.
The uncrewed module — of which a scaled-down mock-up was unveiled to the press on 22 October — will travel on board a Korea Space Launch Vehicle-2 rocket and is designed to carry a lunar rover weighing 10–20 kilograms, which will look for signs of rare minerals on the Moon’s surface. A robotic orbiter will also circle above the lunar landscape for more than a year at an altitude of about 100 km.”

” Scientists at the South Pole have detected a collection of warp speed neutrinos from deep space that could help explain the origins of the universe.
A team from the mighty IceCube telescope laboratory in Antarctica will reveal their findings in tomorrow’s Science journal.
The experts’ 28 intergalactic subatomic particles were detected by the Cherenkov radiation emitted when they (unusually – most neutrinos go right through the Earth without stopping) hit something within a cubic kilometre of intrumented-up polar ice at the South Pole. They are thought to have originated from outside the Solar System, and likely from outside our galaxy, the Milky Way.
Having identified the particles, the boffins believe that they can gain new insight into the workings of black holes, pulsars and other wonders of space that emit the subatomic particles.”
Not being scientists by any stretch of the imagination , we have little to add to the discussion of “warp speed neutrinos” but found the topic interesting to say the least . The significance of the find escapes us but we are fascinated nevertheless .
” Scientists say that solar activity is stranger than in a century or more, with the sun producing barely half the number of sunspots as expected and its magnetic poles oddly out of sync.
The sun generates immense magnetic fields as it spins. Sunspots—often broader in diameter than Earth—mark areas of intense magnetic force that brew disruptive solar storms. These storms may abruptly lash their charged particles across millions of miles of space toward Earth, where they can short-circuit satellites, smother cellular signals or damage electrical systems.
Based on historical records, astronomers say the sun this fall ought to be nearing the explosive climax of its approximate 11-year cycle of activity—the so-called solar maximum. But this peak is “a total punk,” said Jonathan Cirtain, who works at the National Aeronautics and Space Administration as project scientist for the Japanese satellite Hinode, which maps solar magnetic fields.”
Are the lights about to go out ? End times anyone ?
