    I shared these on another site, and by the time i did i typed out basically a mini-thesis so i want to share with all the freeples! [ Concerning CO2 levels and heating on Venus, Mars and Earth ] CO2 has it's limits as a green house gas and it is a very low pressure, compared to Venus which is a very large pressure of CO2. Of course on earth CO2 was at over 1900 PPM during the Jurassic period but somehow dinosaurs were not running around on fire for some reason, of course plants loved that environment, which is...

    Earth 4.4 billion years ago was flat and almost entirely covered in water with just a few small islands, new research suggests. Scientists came to the conclusion after analysing tiny zircon mineral grains from a region of Western Australia containing the oldest rocks ever found. “The history of the Earth is like a book with its first chapter ripped out with no surviving rocks from the very early period, but we’ve used these trace elements of zircon to build a profile of the world at that time,” says lead researcher Antony Burnham, from the Australian National University. “Our research indicates...

    The Washington Post ^ | 04/22/2017 | Joel Achenbach
    The March for Science materialized as a global event on six continents — and cheered on by scientists on a seventh, Antarctica. On the National mall, the crowd has been large, with thousands of people gathered on the grounds of the Washington Monument and lines for the security checkpoints stretching for more than two blocks. Rain has varied from light to borderline apocalyptic, but that didn’t stop people from dancing when Thomas Dolby performed his 1982 blockbuster hit “She Blinded Me With Science.” The march proper is scheduled for 2 p.m., and will proceed down Constitution Avenue to the foot...

    We love Mother Earth and look forward to Earth Day, April 22. These are exciting times for energy, as innovation improves the conversion of wind, solar and geothermal heat into power for our offices, homes and electric cars. Our lives improve as energy options increase. On a day we celebrate the Earth, it is reasonable for people to also acknowledge the role fossil fuels play in helping maintain and even improve our planet's condition. Fossil fuels continue providing most of our energy and will do so for generations to come. Without fossil fuels, we cannot build a single solar panel...
  • Asteroid to Fly Safely Past Earth on April 19 (Asteroid 2014 JO25, Diameter = 2,000 feet)

    NASA ^ | 4/6/17
    A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19 at a distance of about 1.1 million miles (1.8 million kilometers), or about 4.6 times the distance from Earth to the moon. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size. The asteroid, known as 2014 JO25, was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona -- a project of NASA's NEO Observations Program in collaboration with the University...

    Worship and Service of Creation It is easy to read what Paul says in Romans 1:25—“they exchanged the truth about God for the lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen,” in a purely negative light as describing the very basis of paganism and the worst form of idolatrous narcissism. However, we cannot deny the seductive beauty and power of such a creation. A new study has found that merely watching nature documentaries boosts people’s emotions of awe, contentedness, joy and amusement. By the same token, such activity reduces “feelings of nervousness,...

  • NASA: Earth's Last Full Magnetic-Pole Reversal Occurred 780,000 Years Ago --"We Are Over Due"

    The Daily Galaxy ^ | 1 Feb, 2016
    The Earth’s continuously changing magnetic field surrounds the planet like an invisible force field – deflecting highly charged solar particles. Reversals are the rule, not the exception. Earth has settled in the last 20 million years into a pattern of a pole reversal about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal, the Brunhes-Matuyama, that occurred around 780,000 years ago. A temporary reversal, the Laschamp event, occurred around 41,000 years ago, and lasted less than 1,000 years with the actual change of polarity lasting around 250 years. Our planet’s history...

    Life on Earth may have made its mark on the moon billions of years before Neil Armstrong’s famous first step.Observations by Japan’s moon-orbiting Kaguya spacecraft suggest that oxygen atoms from Earth’s upper atmosphere bombard the moon’s surface for a few days each month. This oxygen onslaught began in earnest around 2.4 billion years ago when photosynthetic microbes first flourished (SN Online: 9/8/15), planetary scientist Kentaro Terada of Osaka University in Japan and colleagues propose January 30 in Nature Astronomy.The oxygen atoms begin their incredible journey in the upper atmosphere, where they are ionized by ultraviolet radiation, the researchers suggest.

  • Heat from Earth’s core could be underlying force in plate tectonics

    University of Chicago ^ | 17 Jan, 2017 | Greg Borzo
    For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. The new findings also challenge the theory that underwater mountain ranges known as mid-ocean ridges are passive boundaries between moving plates. The findings show the East Pacific Rise, the Earth’s dominant mid-ocean ridge, is dynamic as heat is transferred. David B. Rowley, professor of geophysical sciences at the University of Chicago, and fellow researchers came to the conclusions...

    Deep within a mine in Canada, there is a pool of water bubbling out of the ground. It’s close to 2 miles below the surface of the earth and, according to the scientists who discovered it, it’s been there for 2 billion years, making it the oldest pool of water in the world.Previously that record was held by a pool further up in the mine, about 1.5 miles down, which was discovered in 2013 and given the age of 1.5 billion years.The scientists date the water by analysing the gases trapped inside. As the CBC explains, gases like helium...

    Popular Mechanics ^ | 8/30/2016 | Avery Thompson
    On Saturday, astronomers discovered a new asteroid, just a few hours before it almost hit us. The asteroid is called 2016 QA2, and it missed the Earth by less than a quarter of the distance to the moon. That puts it about three times as far away from Earth as our farthest satellites. And we never saw it coming. So how did 2016 QA2 sneak up on us like that? For this particular asteroid, the answer seems to be that it has a very peculiar orbit. It's highly elliptical, which means it can usually be found hanging out by either...

    Our solar system is in a unique area of the universe that's conducive to life, says John Webb and his colleagues at the University of New South Wales, who have carried out intensive study that threatens to turn the world of theoretical physics upside down. The team studied the fine structure in the spectral lines of the light from distant quasars from data from the Very Large Telescope (VLT) in Chile with stunning results that showed that one of the constants of nature --the Alpha appears to be different in different parts of the cosmos, supporting the theory that our...

  • NASA plans to launch study of asteroid that could destroy Earth (Bennu in 2135 scenario)

    New York Post ^ | 7/31/15 | Eileen AJ Connelly
    Paging Bruce Willis! NASA is planning to launch a probe to study an asteroid that could one day pulverize the Earth. The asteroid, named Bennu, crosses Earth’s orbit once every six years and has gotten ever closer since it was discovered in 1999, astronomers told the Sunday Times of London (paywall). In 2135, Bennu will fly between the moon and Earth — a hair’s breadth in space terms, the Times reported. That’s so close that gravity from the Earth could effect Bennu’s orbit, “potentially putting it on course for the Earth later that century,” said Dante Lauretta, a professor of...

    GENEVA (Reuters) - The earth is on track for its hottest year on record and warming at a faster rate than expected, the World Meteorological Organization (WMO) said on Thursday. Temperatures recorded mainly in the northern hemisphere in the first six months of the year, coupled with an early and fast Arctic sea ice melt and "new highs" in heat-trapping carbon dioxide levels, point to quickening climate change, it said. June marked the 14th straight month of record heat, the United Nations agency said. It called for speedy implementation of a global pact reached in Paris last December to limit...

    Explanation: What's older than these ancient trees? Nobody you know -- but almost everything in the background of this picture. The trees are impressively old -- each part of the Ancient Bristlecone Pine Forest located in eastern California, USA. There, many of the oldest trees known are located, some dating as far back as about 5,000 years. Seemingly attached to tree branches, but actually much farther in the distance, are the bright orbs of Saturn (left) and Mars. These planets formed along with the Earth and the early Solar System much earlier -- about 4.5 billion years ago. Swooping down...
