"Ten Times More Powerful than Hubble!" --Chile's Giant Magellan Telescope Will Search for Earth 2.0 (Today's "Galaxy" Stream)  

    "We're seeking to make the most sensitive instrument in the history of mankind," said Andrew Szentgyorgyi, associate director of the solar, stellar, and planetary sciences division at the Harvard-Smithsonian Center for Astrophysics. "We're looking to find Earth 2.0." On a remote mountain top in Chile's Atacama Desert, one of a new class of what are called "extremely large telescopes" known as the GMT, has been under construction since 2015, and is poised to b...

Recycling the Planet --"Heat from Earth's Core Drives Plate Dynamics"  

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-oce

"With Alien Eyes" --ALMA Observatory Can Now Study Our Sun Across the Entire Electromagentic Spectrum (VIDEO)  

"We're accustomed to seeing how our Sun appears in visible light, but that can only tell us so much about the dynamic surface and energetic atmosphere of our nearest star," said Tim Bastian, an astronomer with the National Radio Astronomy Observatory in Charlottesville, Virginia in the USA. "To fully understand the Sun, we need to study it across the entire electromagnetic spectrum, including the millimeter and submillimeter portion that ALMA can observe. "Our human window on the...

Window On Our Climate Future: Ice Sheet 22,000 Years Ago Three Times Greater Than Greenland's --"Lowered Global Sea Level 120 Meters" (VIDEO)  

One of the major questions facing us today is how the present ice sheets in Greenland and Antarctica will react to climate change. Simply put, the more we understand of the mechanisms that drove ice sheets to collapse in the past, the better we will be able to predict what will happen in the future. The Eurasian ice sheet was the third largest ice mass during the Last Glacial Maximum some 22,000 years ago. Alongside the Antarctic and North American ice sheets it lowered the global sea l

The Milky Way's Destiny? --"Dark Matter Clouds are Killing Galaxies Throughout the Cosmos" (VIDEO)  

  Through the cosmos, galaxies are dying off, and the question astronomers want answered is, "what's killing them?" New research by a global team of researchers, based at the International Centre for Radio Astronomy Research (ICRAR), has revealed that a study of 11,000 galaxies shows their gas —the lifeblood for star formation— is being violently stripped away on a widespread scale throughout the local Universe. "During their lifetimes, galaxies can inhabit halos of different siz...

Fish in Space -- "Traveling Aboard the ISS Suffered Immediate Microgravitational Stress” (VIDEO)  

    Life in so-called 'microgravity' environments—where the force of gravity is considerably less than on Earth—can cause significant problems for the human body. Astronauts who spend a number of months in space have been shown to suffer from reduced bone mineral density, leading to skeletal problems as well as fluid shift, increase in blood pressure, and dizziness. Surprisingly, the loss of calcium starts at least 10 days after launch in astronauts in Skylab Flights, but t...

NASA: New Search Technology for Detecting Life on Alien Worlds --"10,000 Times More Powerful"

But looking for these molecules on Mars or other planetary surfaces has been a major challenge. The Curiosity rover exploring Mars attempted to accomplish this, but the rover's experiments to identify organic chemicals in Martian samples were complicated by reactions with other materials in the samples

"Is There Technology Around Tabby's Star?" --Berkeley SETI's Green-Bank Telescope Investigation of the "Alien Megastructure" Star (LIVESTREAM/VIDEO)  

    In a distant spiral arm of our Milky Way galaxy, some 1,480 light-years from Earth, a star, KIC 8462852, but informally called "Tabby's Star" or "Boyajian's Star" is acting in ways the world's astronomy community has never seen before, defying all known explanations. At random intervals, its light dims by as much as 22 percent, and appears to have gotten dramatically darker over the past century. Tabby's star has provoked so much excitement, with speculation that it hosts a

NASA's Hubble Space Telescope --Star-Casted Shadows Reveal Alien Planets  

    Searching for planets around other stars is a tricky business. They're so small and faint that it's hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star. The planet itself is not casting the shadow. But it is doing some heavy lifting by gravitationally pulling on material near the star and warping t

Everything you need to know about gravitational waves. In February 2016 scientists announced the first detection of gravitational waves by humans on Earth. This was a huge, world changing, discovery. The gravitational waves were caused by a pair of colliding black holes 1.3 billion light years away 1.3 billion years ago. This video summaries all the of the mind blowing facts about the gravitational waves and describes LIGO, the incredibly sensitive telescope that detected them.

NASA's Chief Scientist Ellen Stofan Resigns - "Predicts Proof of Alien Life in 20 Years" (VIEW VIDEO)  

Ellen Stofan, NASA's chief scientist, has left the space agency for what she describes as other "adventures." Stofan is believed to have left her post before Christmas last month. Her expertise was focused on the geology of Venus, Mars, Saturn's moon Titan, and Earth. Stofan was an associate member of the Cassini Mission to Saturn Radar Team and was a co-investigator on the Mars Express Mission's MARSIS sounder. She also was principal investigator on the Titan Mare Explorer, a proposed m

NASA Proposes "Mars Ice Dome" for Future Manned Missions  

When astronauts set foot on Mars, they may stay for months rather than days as they did during Apollo missions to the moon. The surface of Mars has extreme temperatures and the atmosphere does not provide adequate protection from high-energy radiation. These explorers will need shelters to effectively protect them from the harsh Martian environment and provide a safe place to call home. For researchers at NASA's Langley Research Center in Hampton, Virginia, the best building material ...
