POPS Mystical Martian Moon Phobos Can you imagine id the man & his wife who discovered this moon could see the wonderful pictures today? Also can we imagine that in another 122 years what they will tell about these magnificent moons?

POPSDeath rays from space
"Every square centimeter on the top of the Earth's atmosphere is hit by several cosmic rays per second," Fields says. "This is forever going on." At present, the average human receives the equivalent of about 10 chest X-rays per year from cosmic rays. We shouldn't be alarmed by this, since it is just part of the natural background radiation under which humans and our ancestors have been exposed to for eons. Indeed, cosmic-ray-induced mutations may sometimes be beneficial. "It is clear that in some way cosmic rays shaped evolution of organisms on Earth," says Franco Ferrari from the University of Szczecin in Poland. Although 30 light-years is small on a galactic scale, Fields thinks it likely that Earth has been caught in a supernova "kill radius" as many as a dozen times over our 4.5-billion-year history. However, a nearby supernova is not the only way to increase the cosmic ray intensity. As our Sun orbits around the galactic center, it regularly passes through one of th

POPSCould Earth Be Hit, Like Jupiter Just Was? "Small risk" "Billions of years ago, impacts were far more common. Our moon retains a record of the pummeling it and Earth took: the moon's craters remain, while on Earth, most scars of ancient impacts have been folded back into the planet or weathered away. Today's solar system is far less crowded, and in fact Jupiter, having more mass and gravity, scoops up a lot of the dangerous objects, as does the sun. Currently just one NEO of all the objects scientists are tracking poses any significant chance of hitting the Earth — 2007 VK184. If this roughly 425-foot-wide (130 meters) asteroid hit our planet, it would strike with an energy of roughly 150 million tons of TNT, or more than 10,000 times that of the atom bomb dropped on Hiroshima."

POPSThe scale of destruction Kashmir earthquake, 2005 178 megatone TNT Caused damage in Islamabad, 65 miles away. Mount St. Helena eruption, 1980 500 megatons TNT Devastaled several hundred square mil areas San Francisco eartquake, 1906 1 gigaton TNT Caused $5.6 billions in property damage Krakatoa eruption, 1883 5.6 gigatons TNT Worldwide effects included the destruction of 165 villages and towns 10 km asteroid impact, 65 millions years ago 100.000 gigatons. TNT Caused final extinction of dinosaurs and many other species An asteroid impact with the Earth may have caused the extinction of the dinosaurs. The Alvarez Asteroid Theory explains the huge K-T (Cretaceous-Tertiary) mass extinction 65 million years ago by a large asteroid hitting the Earth off the Mexican Yucatan peninsula. This impact would have caused severe climactic changes leading to the demise of many groups of organisms, including non-avian dinosaurs.

POPSJupiter Impact Photo Spectra collected by various observatories may help identify what the impactor was, since a large amount of water at the impact location would hint at a comet as the source. “We will also compare the observations with those collected during 15 years ago,” since that was a known comet, Marchis says. Without having seen it, scientists can’t tell how large the object was. “But the impact scar we’re seeing is about the same size as one of Jupiter’s big storms, Oval BA, Fletcher told New Scientist. “That, I believe, is about the size of the Earth.” Marchis says Jupiter may be protecting Earth from getting hit by such objects. “The solar system would have been a very dangerous place if we did not have Jupiter,” he told New Scientist. “We should thank our Giant Planet for suffering for us. Its strong gravitational field is acting like a shield protecting us from comets coming from the outer part of the solar system.” newscientist.com

POPSJupiter Struck making earth size impact Really makes ya wonder. This was a neo (near earth object) that struck and was not even detected. Just imagine if was off by a little bit more and it was us instead of Jupiter. Here one minute and in a flash evaporated. Dead so fast you didn't even know you were gone. Another reason I feel we should all spend life loving life and others. letting those you love know you do and embracing life to the fullest. Took me years to reach this plane in life where i get amazed even watching a simple butterfly in flight, much less all the other wonders in this universe. Downside of this enlightenment though is you also take more notice of the horrors and crime a lot more. So more or less like a rollarcoaster ride in life with it's shigh's and lows...lol

POPSWe Pay our taxes to be left in the dark ? I for one would like to know if I have only awhile left to live. Like to say my farewells and close life at peace. I don't think it is right for them to be the only ones who know especially when it is our money that is paying for their salary's and projects. It's our government, not to be ruled like a dictatorship.

POPSAmericans unprepared for doomsday "Even assuming someone eventually developed an above-ground super-house able to withstand the 1,200-degree temperature and massive force of lava and ash rain that would result from a globe-shattering asteroid impact, its occupants would be unprepared for the ensuing radical climate change," Olheiser said. "By the same token, the average household lacks the 1.2 million gallons of heating oil needed to withstand the prolonged sub-zero temperatures of another protracted Ice Age—perhaps the most shocking of the public's many oversights."
