No one can realistically argue that humans haven’t dramatically transformed the face of the planet. View original here: "The Anthropocene": Are We Living in a New Planetary Era? NASA Study on Climate Change in 21st Century Says "Yes"

All life on Earth all sprang from the same single-celled organisms that first populated the planet, so how did life grow in size from bacteria to the blue whale? Here is the original:  Scale of Life from Bacteria to Blue Whale Occured in Two Great Leaps

A new analysis of the geological record of the Earth’s sea level, carried out by scientists at Princeton and Harvard universities used a novel statistical approach that reveals the planet’s polar ice sheets are vulnerable to large-scale melting even under moderate global warming scenarios. Such melting would lead to a large and relatively rapid rise in global sea level. Read the rest here:  Are the Polar Caps Threatened?

Setting sail has always been the image of a new undertakings, of exploration, of adventuring beyond the known lands and into history.  Simply running out of Earth oceans is no reason to stop. View post: New NASA Discovery Mission: To Sail the Foggy Seas of Saturn’s Titan

This video by the American Museum of Natiral History takes viewers from the Himalayas through our atmosphere and the cold silent reaches of space with its mysterious quasars and supernovae back to the to the afterglow of the Big Bang. Go here to see the original: The Observable Universe (VIDEO)

New Study of Meteorite Provides More Evidence for Ancient Life on Mars In 1996, when scientists examined a meteorite from Mars previously uncovered in Antarctica, they were intrigued by what looked like microscopic fossils of ancient Martian life forms. Now, using new technology that wasn’t available 13 years ago, NASA scientists have found further evidence that the materials and structures in the meteorite are likely signs of ancient life, rather than the results of inorganic processes..

Astronomers announced today that they have discovered a “super-Earth” orbiting a red dwarf star 40 light-years from Earth.  Astronomers found the new planet using the MEarth (pronounced “mirth”) Project – an array of eight identical 16-inch-diameter RC Optical Systems telescopes that monitor a pre-selected list of 2,000 red dwarf stars. Although the super-Earth is too hot to sustain life, the discovery shows that ground-based technologies are capable of finding [...]

Some scientists say that there really is something Kryptonian among us, brought to Earth by impacting objects from outer space – only it’s the noble gas, not a noble hero, because there’s nothing more Kryptonian than Krypton itself.  A new study shows that Earth’s atmosphere may have been swept up from interplanetary gas clouds instead of coming from within the planet. Of course such statements are only a matter of timing – everything originally came from gas clouds, as interstellar [...]

“Comets are a whole different ball game. They don’t do that circular thing. They come straight in from far, far out — and you don’t see them coming until they push out a tail only a few years before they would enter the inner solar system See the original post: Are Comet Impacts #1 Extraterrestrial Threat to Earth?

A team of MIT scientists recorded a nearly simultaneous world-wide increase in methane levels -the first increase in ten years. What baffles the team is that this data contradicts theories stating humans are the primary source of increase in greenhouse gas. It takes about one full year for gases generated in the highly industrial northern hemisphere to cycle through and reach the southern hemisphere. See the original post here:  MIT Team Asks: Is Increase in Greenhouse Gas Part of Natural Cycle? [...]
