Solar radiation caused periodic ice ages to end 19,000 years agoAugust 7th, 2009 WASHINGTON - In a new research, scientists have concluded that slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis made the periodic ice ages to finally come to an end about 19,000 years ago. The research, by scientists from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.
Delhi company sells 50,000 solar goggles in two daysJuly 22nd, 2009 NEW DELHI - The excitement of the century's longest total solar eclipse was quite evident from the sales of Gnomon Astrotech, a Delhi based firm that sold a record 50,000 solar goggles across India in just two days. The company imported a large number of solar goggles, solar filter films and telescopes from a US-based firm to meet the huge demand during the celestial spectacle.
Total solar eclipse in most of ChinaJuly 22nd, 2009 CHONGQING - A total solar eclipse was observed at many places in China Wednesday morning, officials said. At 9.15 a.m., many places in the upper reaches of China's longest river, the Yangtze, were engulfed in total darkness.
How animals react to solar eclipseJuly 21st, 2009 MUMBAI - Did you know animals and birds often prepare for sleep or behave confusedly during total solar eclipse? Well, here are some other little known facts about solar eclipse. - The longest recorded duration for a total solar eclipse is 7.5 minutes.
Gujarat launches website for solar eclipseJuly 20th, 2009 SURAT - The Gujarat government Monday launched a website dedicated to the total solar eclipse of July 22, an official here said. The state government launched the website solareclipsesurat.in jointly with the Surat Municipal Corporation and the Southern Gujarat Chamber of Commerce and Industry.
Solar activity has big impact on earth's climateJuly 18th, 2009 WASHINGTON - A high in solar activity impacts the earth in a way that resembles the devastating El Nio, releasing more energy than a million Hiroshima bombs, according to a new study. The study shows that as the sun reaches maximum activity, it heats cloud-free parts of the Pacific Ocean enough to increase evaporation, intensify tropical rainfall and the trade winds, and cool the eastern tropical Pacific.
Radioactive isotope in ice core record reflects solar activity over 600 yearsJuly 4th, 2009 WASHINGTON - Scientists have analyzed Beryllium-10, a radioactive isotope, found from the NGRIP ice core, Greenland, which reflects solar activity over the past 600 years. Beryllium-10, a radioactive isotope, is produced in cosmic ray showers.
Virtual model of sunspots may unlock Sun's mysteriesJune 19th, 2009 WASHINGTON - Scientists have created the first-ever comprehensive computer model of sunspots, a breakthrough that will help scientists unlock mysteries of the sun and its impacts on Earth. Sunspots are associated with massive ejections of charged plasma that can cause geomagnetic storms and disrupt communications and navigational systems.
Solar activity in 2013 may register lowest peak since 1920sJune 13th, 2009 WASHINGTON - Estimates indicate that solar activity will peak in 2013, but it would be the lowest peak recorded since the 1920s. The sun was expected to hit a low in 2008 as part of its normal 11-year cycle of activity.
Broken dwarf planet may have scarred the Moon in early solar systemJune 11th, 2009 London, June 11 (ANI: A new analysis of craters of the Moon has suggested that the shattered remnants of a dwarf planet may have bombarded the inner planets in the early solar system. According to a report in New Scientist, several large impact scars on the moon appear to be around 3.9 billion years old, suggesting that the Earth and other objects of the inner solar system were heavily pounded at that time.
Astronomers detect planet forming disk orbiting twin sunsJune 11th, 2009 WASHINGTON - Astronomers have found a planet forming disk orbiting twin suns in images captured from radio telescopes. The sequence of images, collected with the Smithsonian's Submillimeter Array (SMA), provide an unusually vivid snapshot of the process of formation of giant planets, comets, and Pluto-like bodies.
World's largest solar telescope offers better understanding of Sun's magnetic fieldMay 29th, 2009 WASHINGTON - The world's largest solar telescope, which can capture the Sun's magnetic field better than other telescopes, is now operational. The new 1.6-meter clear aperture solar telescope, the largest of its kind in the world, is housed at the New Jersey Institute of Technology in Newark, New Jersey, US.
Dull Sun could spark off next "Little Ice Age" in futureMay 5th, 2009 WASHINGTON - Some scientists say the prolonged lull in solar activity hints towards the next "Little Ice Age", which could occur in the near future. The sun is the least active it's been in decades and the dimmest in a hundred years.
Atmospheric engineering scheme to fight global warming could diminish solar powerApril 20th, 2009 WASHINGTON - A new study has determined that a widely discussed "atmospheric engineering" scheme intended to combat global warming could have unanticipated consequences in reducing the effectiveness of certain kinds of solar power around the Earth. In the study, the National Oceanographic and Atmospheric Administration's Daniel M.
Solar eruptions could disrupt power grids, telecom by 2012January 12th, 2009 WASHINGTON - Extreme solar eruptions could disrupt communications, power grids and other technology on earth by 2012. These eruptions are expected to increase in frequency and intensity towards the next solar maximum cycle which peaks in 2012, up from the current minimum of its 11-year activity cycle.
