    Full title: Ancient bubbles in Australian rocks show early Earth's air weighed less than half today's atmosphere Air bubbles trapped in 2.7 billion-year-old Australian rock suggest the Earth's atmosphere weighed less than half of today and was much thinner than previously thought. Researchers analysed the size of air bubbles that formed at the top and bottom of lava flows along the Beasley River in Western Australia's Pilbara region almost three billion years ago and used the data to calculate the atmospheric pressure at the time. The results suggest that the air at the time exerted at most half the pressure...

    But good luck breathing in the bone-crushing gravity.A newly discovered star is unlike any ever found. With an outermost layer of 99.9 percent pure oxygen, its atmosphere is the most oxygen-rich in the known universe. Heck, it makes Earth's meager 21 percent look downright suffocating. The strange stellar oddity is a radically new type of white dwarf star, and was discovered by a team of Brazilian astronomers led by Kepler de Souza Oliveira at the Federal University of Rio Grande do Sul in Brazil. The star is unique in the known pool of 32,000 white dwarf stars, and is the...

    Those who think the political war on carbon will cool the globe or keep climate stable need to study climate history. Temperatures on Earth dance to a cyclic rhythm every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles. The daily solar cycle causes continual changes in temperature for every spot on Earth. It produces the frosts at dawn, the mid-day heat and the cooling at sunset. It is regulated by rotation of the Earth. Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit...

    UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago -- 300 million years earlier than previous research suggested. The discovery indicates that life may have begun shortly after the planet formed 4.54 billion years ago. The graphite is older than the zircon containing it, the researchers said. They know the zircon is 4.1 billion years old, based on its ratio of uranium to lead; they don't know how much older the graphite is.The carbon contained in the zircon has a characteristic signature -- a specific ratio of carbon-12 to carbon-13 -- that...

    Scientists have found further evidence for the existence of an elusive intermediate implicated in chemical reactions that degrade atmospheric pollutants. A new method of directly detecting the simplest form of this intermediate, as well as more measurements of the intermediates reactivity, provide indications that atmospheric models need to improve how they account for them.More than 50 years ago, German chemist Rudolf Criegee proposed that alkenes in the atmosphere, released either by plants or human activities, degrade by reacting with ozone to form a cyclic ozonide. One of the products formed when this ozonide falls apart is a carbonyl oxide called...

    Billions of years ago, before Earth's atmosphere had oxygen, it periodically possessed a "haze" of organic chemicals including methane, boffins have discovered. During these periods the planet's air was more like that of Titan, ice moon of Saturn, than the stuff we breathe today. "Models have previously suggested that the Earth's early atmosphere could have been warmed by a layer of organic haze," says Dr Aubrey Zerkle of Newcastle uni. "Our geochemical analyses of marine sediments from this time period provide the first evidence for such an atmosphere." According to Zerkle and his colleagues, during the period 2.5 to 2.65...

    WASHINGTON (AFP) An international team of researchers has found that the atmosphere's ability to cleanse itself of pollutants and other greenhouse gases, except carbon dioxide, is generally stable. The study, published in Friday's edition of the journal Science, comes amid a fierce debate over whether, as some experts believe, the atmosphere's self-cleaning ability was fragile and sensitive to environmental changes.

    WASHINGTON (AFP) The upper reaches of Earth's atmosphere are unexpectedly shrinking and cooling due to lower ultraviolet radiation from the sun, US scientists said Thursday. The sun's energy output dropped to unusually low levels from 2007 to 2009, a significantly long spell with virtually no sunspots or solar storms, according to scientists from the National Center for Atmospheric Research in Boulder, Colorado. During that period, the thermosphere, whose altitude ranges from about 55 to 300 miles (90 to 500 kilometers), shrank and contracted from the sharp drop in ultraviolet radiation, said the study published in the American Geophysical Union's...

A recent Texas A&M University study, based on satellite data from the National Aeronautics and Space Administration, warned that if water vapor levels in the atmosphere continue to rise, it "could guarantee" an increase of several degrees Celsius in the Earth's temperatures over the next century. These scientists warned of potential "positive feedback," in which water vapor traps heat near the surface, the warmer temperatures cause increasing ocean surface...

    Could dandruff be altering the worlds climate? Along with fur, algae, pollen, fungi, bacteria, viruses and various other bio-aerosols wafting around in the atmosphere, it may well be. A global study has found that tiny fragments of biological detritus are a major component of the atmosphere, controlling the weather and forming a previously hidden microbial metropolis in the skies. Besides their climatic influence, they may even be spreading diseases across the globe. Scientists have known for some time that aerosols of soot, dust and ash can influence climate by reflecting or absorbing the Suns rays and by providing the condensation...

    While the entire northeast of the United States was digging out from a huge blizzardusually a sign of cold weathera meeting on "the climate challenge" was occurring in London, England and "an independent report" by the Institute for Public Policy Research (Great Britain), The Australia Institute, and the Center for American Progress announced that "an ecological time bomb is ticking away" that will plunge the world into chaos due to the heat said to be generated by greenhouse gas emissions. This kind of lunacy is intended to impose caps on the use of energy everywhere. It is the goal of...

    Asteroid shaves past Earth's atmosphere 13:59 23 August 04 news service The closest observed asteroid yet to skim past the Earth without hitting the atmosphere, was reported by astronomers on Sunday. The previously unknown object, spanning five to 10 metres across, has been named 2004 FU162. It streaked across the sky just 6500 kilometres - roughly the radius of the Earth - above the ground on 31 March, although details have only now emerged. The MIT Lincoln Laboratory's asteroid-hunting LINEAR telescope in Socorro, New Mexico,US, observed the new object four times over a 44-minute period, several hours before its...

    Global Warming's Latest Hot Topic Causes Yet More Nasty ArgumentsClimate change research is a giant scientific sandbox. The subject is so complex, the data sources spread across so many disciplines, and the analytical tools so new and powerful that just about any scientist can stick in his shovel someplace and come up with a new -- and probably plausible -- result. There even remains -- in the United States, at least -- controversy over whether global temperatures are rising and, if so, how much. A recent paper in the British journal Nature claims to have found a way out of...
  • Increasing Greenhouse Gases Lead To Dramatic Thinning Of The Upper Atmosphere

    The highest layers of the Earth's atmosphere are cooling and contracting, most likely in response to increasing levels of greenhouse gases, according to a new study by scientists at the Naval Research Laboratory (NRL). This contraction could result in longer orbital lifetimes for both satellites and hazardous space debris. In a paper to be published February 5 in the Journal of Geophysical Research - Space Physics, John Emmert, Michael Picone, Judith Lean, and Stephen Knowles report that the average density of the thermosphere has decreased by about 10 percent during the past 35 years. The thermosphere is the highest layer...

    Military interest in space became intense during and after World War II because of the introduction of rocket science, the companion to nuclear technology. The early versions include the buzz bomb and guided missiles. They were thought of as potential carriers of both nuclear and conventional bombs. Rocket technology and nuclear weapon technology developed simultaneously between 1945 and 1963. During this time of intensive atmospheric nuclear testing, explosions at various levels above and below the surface of the earth were attempted. Some of the now familiar descriptions of the earth's protective atmosphere, such as the existence of the Van Allen...

    <p>Beginning 8,000 years ago, atmospheric levels of carbon dioxide began to rise as humans started clearing forests, planting crops and raising livestock, a scientist said Tuesday. Methane levels started increasing 3,000 years later.</p> <p>The combined increases of the two greenhouse gases implicated in global warming were slow but steady and staved off what should have been a period of significant natural cooling, said Bill Ruddiman, emeritus professor at the University of Virginia.</p>

    WASHINGTON (Reuters) - The solar wind pries open immense cracks in the Earth's magnetic field, holding them apart while it gushes through to cause geomagnetic storms, scientists reported on Wednesday. The findings could help scientists better predict the storms, which can disrupt power, satellites and communications and endanger astronauts, the U.S. space agency NASA (news - web sites) said. "We think we have solved an old and long-standing controversial discussion of how this process of crack formation really works," Harald Frey of the University of California, Berkeley, who led the study, told a news conference. "Now that we know these...

    Source: NASA/Goddard Space Flight Center Date: 2003-06-18 Headless Comets Survive Plunge Through Sun's Atmosphere A run through the jungle is too easy; for the ultimate reality show contest, try a race through the Sun's atmosphere, where two comets recently lost their heads. The tails from a pair of comets survived a close encounter with the Sun, even after the Sun's intense heat and radiation vaporized their heads (nuclei and coma), an extremely rare event photographed by the Solar and Heliospheric Observatory (SOHO) spacecraft. On May 24, 2003, a pair of comets arced in tandem towards the Sun, their paths taking...
