Ancient Worlds Could Be Kept 'Alive' by Gravitational Nudges
Tucson AZ (SPX) Jul 01, 2014
For more than three billion years now, Earth's ability to support life has been a delicate balancing act. Climatic periods of severe cold or hot have brought life to its knees. Glaciers covered the planet in the "snowball Earth" epoch, which ended some 650 million years ago. During the extremeheat of the early Triassic period around 250 million years ago, tropical sea temperatures exceeded 100 degrees Fahrenheit. But the temperature pendulum has always swung back from these extremes, thanks in lar ... read more

Distant comet 'sweats' two glasses of water per second Unprecedented measurement of a deep-space comet has found the icy body to be losing about two small glasses of water every second, the European Space Agency (ESA) said on Monday. ... more		Remarkable White Dwarf Star Possibly Coldest, Dimmest Ever Detected A team of astronomers has identified possibly the coldest, faintest white dwarf star ever detected. This ancient stellar remnant is so cool that its carbon has crystallized, forming - in effect - ... more		NASA's STEREO Maps Much Larger Solar Atmosphere Than Previously Observed Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, u ... more
				Time-traveling photons connect general relativity to quantum mechanics Scientists have simulated time travel by using particles of light acting as quantum particles sent away and then brought back to their original space-time location. This is a huge step toward marryi ... more		Black hole trio holds promise for gravity wave hunt The discovery of three closely orbiting supermassive black holes in a galaxy more than four billion light years away could help astronomers in the search for gravitational waves: the 'ripples in spa ... more

New NASA Model Gives Glimpse into the Invisible World of Electric Asteroids Space may appear empty - a soundless vacuum, but it's not an absolute void. It flows with electric activity that is not visible to our eyes. NASA is developing plans to send humans to an asteroid, ... more		Whale of a target: harpooning space debris Faced with the challenge of capturing tumbling satellites to clear key orbits, ESA is considering turning to an ancient terrestrial technology: the harpoon. Used since the Stone Age, first to spear ... more		EU leaders plot defence boost in shadow of Denmark drones Germany wants to allow military to shoot down drones Leaked info: China's Taiwan invasion plans get help from Russia		Mysterious 'Magic Island' appears on Saturn moon Now you don't see it. Now, you do. And now you don't see it again. Astronomers have discovered a bright, mysterious geologic object - where one never existed - on Cassini mission radar images of Lig ... more
				Scientists say decaying dark matter might be responsible for x-ray emission Dark matter is everywhere. According to astronomers, it makes up some 80 percent of all matter in the universe. But since it doesn't absorb or emit light, scientists have never seen dark matter. They don't even know what it is exactly. ... more		Spitzer Spies an Odd, Tiny Asteroid Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small a ... more

Researchers Detect Smallest Force Ever Measured What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. ... more		Ghost writing the whip "Ghost imaging" sounds like the spooky stuff of frivolous fiction, but it's an established technique for reconstructing hi-res images of objects partly obscured by clouds or smoke. Now a group of re ... more		Philippines quake kills dozens as injured overwhelm hospitals Typhoon Bualoi inflicts death, lasting floods on Vietnam Moldova backs EU in elections marred by Russian interference		Laser Physics upside down At the Vienna University of Technology a system of coupled lasers has been created which exhibits truly paradoxical behaviour: An increase in energy supply switches the lasers off, reducing the ener ... more
Rosetta's comet: expect the unexpected An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects. The picture was captured on 4 ... more		Quantum mechanism triggers emission of tunable light at terahertz levels Scientists have found that two-dimensional (2D) nanostructures with asymmetric design enable a new quantum mechanism, triggering the emission of tunable light at terahertz frequencies-with unprecede ... more		Nuanced account of stunning patterns in the microwave sky published Following a thorough peer-review process, the researchers who previously announced the detection of B-mode polarization in a patch of the microwave sky have published their findings in the journal P ... more		With light echoes, the invisible becomes visible Scientists at the University of Bonn and the University of British Columbia (Vancouver, Canada) have developed a novel camera system which can see around the corner without using a mirror. Using dif ... more
