Canadian scientists Felix Pharand-Deschenes used satellite images to map the human influence on Earth, depicting how much it has changed, as seen from space. Pharand-Deschenes used data collected by various government agencies to create these striking images. The images show everything, from paved and unpaved roads, light pollution, railways, electrical transmission lines, all the way […]

why is Earth comparatively dry

While analyzing the common accretion-disk model explaining how planets form in a debris disk around the Sun, scientists found that a newly proposed disk model better explains why the Earth is a dry planet. With large swaths of oceans, rivers that snake for hundreds of miles, and behemoth glaciers near the north and south poles, […]

evidence of impending tipping point for Earth

A new paper by 22 international scientists describes the need for better predictive models based on detailed understandings of how the biosphere reacted in the past to conditions like climate change and human population growth to help future scientists better decipher how the biosphere will change as the result of the continued expansion of human […]

Picture of Earth showing if all Earth's water

You’ve probably heard the saying that Earth is mostly water, roughly 70%. Well it turns out that many people have misunderstood the facts and that it’s only the Earth’s surface that is mainly water. To get a better understanding of the limited amount of water on Earth, the USGS gives a visual explanation with one […]

Norris Geysir Basin

A new study from the Australian National University examines defects in rocks found below the earth’s surface in an attempt to better understand how seismic waves travel through the mantle and to gather information that will help geologists better interpret seismological models of the Earth’s internal structure. Defects found in rocks below the Earth’s surface […]

Earth's crust being destroyed

Newly published research shows that the growth rate of the Earth’s continental crust has decreased significantly over the last three billion years, leaving researchers to believe that an early form of plate tectonics began around three billion years ago. The growth rate of the Earth’s continental crust was high during the first 1.5 billion years […]

While climate models can forecast temperature changes and precipitation, they struggle to indicate how climate change will affect the factors that make Earth habitable, such as the availability of water and food. Last week, the Potsdam Institute for Climate Impact Research (PIK) in Germany launched a program to make the actual narratives of possible futures […]

earth-losing-mass

According to some calculations, the Earth is losing 50,000 tonnes of mass every single year, even though an extra 40,000 tonnes of space dust converge onto the Earth’s gravity well, it’s still losing weight. Chris Smith, a microbiologist, and Dave Ansel, a Cambridge University physicist provided the answer in BBC Radio 4’s More or Less […]

'Blue Marble' Image of the Earth Taken from NASA's  Suomi NPP Satellite

NASA’s Earth-observing satellite, Suomi NPP, captured this “Blue Marble” image of Earth on January 24, 2012 using the Visible Infrared Imager Radiometer Suite. As you can see, the HD photo is a vast improvement over the photo taken on December 7, 1972. A ‘Blue Marble’ image of the Earth taken from the VIIRS instrument aboard […]

It has been demonstrated experimentally that a diamond’s trip from deep below the Earth’s surface must be very quick, since lab tests have shown that the gems would burn up in a matter of days, if not hours, if left in the harsh conditions found in the inner crust. The eruptions of diamonds are driven […]

Sandia Combustion Researchers Study Criegee Intermediate Reactions

New research shows that Criegee intermediates react with sulfur dioxide and nitrogen dioxide much more rapidly than previously thought. Because Criegee intermediates oxidize sulfur dioxide so quickly, a major tropospheric sulfate source may be Criegee reactions. These sulfates nucleate atmospheric aerosols, and therefore can form clouds that will help cool the planet by reflecting sunlight […]

Synchotron casting light on air particles

According to a new paper, Criegee biradicals can clean up the atmosphere naturally by reacting with pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. Further, these oxidation reactions can generate nitrate and sulphate  in the atmosphere, which can lead to more cloud formation and thus a cooling effect on planet Earth. Scientists […]

New Data Finds North American Continent Extremely Stable

Researchers at MIT have published their work on the reconstruction of the Wyoming Province. Despite billions of years of turmoil beneath the Earth’s crust, the North American continent remains stable. This stability is what has really grasped the interests of geologists around the world. Like lines in a deeply weathered face, the cracks and fissures […]

Scientists Probe Earth's Core

Scientists discover that the Earth’s core may not be what they originally thought; an iron-oxygen mix. Yes, the liquid outer core of the planet is made of molten iron, but there is something else in there too. Based on laboratory tests, the core density is too low to be comprised of just iron, there has […]
