Widespread Water on Moon But Not Easy to Retrieve

February 27, 2018

A new study, led by Joshua Bandfield of the Space Science Institute in Boulder, Colorado, suggests that water is widely spread across our moon’s surface. It can be found day or night and in many locations and types of terrain. The findings reported in this study were found to contradict previous research. But the study, […]

February 8, 2016

Much has been written about the wide reaching impact of the “Little Ice Age,” a period of global cooling that lasted approximately from the mid-13th to the mid-19th centuries. Now, an international team of researchers say they have come across another extraordinary, extended period of cooling that took place in the northern hemisphere between 536 […]

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water.

NASA Says Water Flows on Mars

September 28, 2015

Today, NASA confirmed evidence of the presence of liquid water flowing on present-day Mars. It’s most likely that any flowing Martian water is salty and not pure. “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve […]

Mercury’s Surface ‘Painted’ With Carbon from Comets

March 30, 2015

A first glance, the planet Mercury looks a lot like our Moon, both gray and pockmarked with craters after being bombarded with meteorites and blasted by the solar wind over the millennia.  Some take the similarity further, referring to them as “twins.” The color of Mercury’s surface though is much darker than the moon, so […]

Volcanic Activity Linked to A Warm and Wet Ancient Mars

November 17, 2014

Exploratory missions to Mars, such as NASA’s Curiosity Rover, have provided more and more evidence that Mars at one time was warm enough for water to flow on its surface. Now a new study published in the journal “Nature Geoscience” has found that those ancient, warm periods on the Red Planet probably took place in […]

Report – Record High Amount of CO2 will be Released in 2014

September 22, 2014

A new report by the Global Carbon Project, an international science/environmental group, shows that the emission of carbon dioxide, one of the world’s top greenhouse gases – which scientists say leads to global warming – will not only rise once again in 2014, but will set a record high of 40 billion metric tons. As […]

Scientists Identify Four New Ozone Depleting Gases in Atmosphere

March 10, 2014

Scientists have identified four new man-made gases in the atmosphere that they say are helping to destroy Earth’s protective ozone layer. Writing in Nature Geoscience, the researchers said that there are about 74,000,000 kilograms of three newly identified chlorofluorocarbons (CFCs) – compounds that only contain the atoms of carbon, fluorine and chlorine – and one […]

Ancient Zircon Reveals Age of Earth’s Crust

February 26, 2014

A tiny sliver of ancient zircon reveals the crust of our planet formed at least 4.4 billion years ago—160 million years after the birth of the solar system, according to a new study. Earth itself is believed to be about 4.5 billion years old. The researchers examined some of the oldest materials ever found on […]

Scientists Find Evidence of Possible Lost Continent

February 26, 2013

Scientists believe they’ve uncovered evidence of a long-lost continent in sand found on an island off the east coast of Africa. The possible proof was found in traces of an ancient mineral believed to be between 660 million and 1.97 billion years, gathered from the beaches of Mauritius. It could provide evidence of a long […]

Scientists Discover How Oceans Store Carbon

July 30, 2012

Scientists have discovered  how carbon dioxide is drawn from the atmosphere and stored  deep in the ocean. According to a new study published in Nature Geoscience, instead of CO2 being evenly absorbed deep into the water over wide areas of the Southern Ocean, it is pulled down and locked away from the atmosphere through localized […]
