POPSFACES 'Like the earth of a hundred years ago our mind still has its darkest Africas, its unmapped Borneos and Amazon basins. In relation to the fauna of these regions we are not yet zoologists, we are mere naturalists and collectors of specimens. ' Aldous Huxley from 'Heaven and Hell' 1954

POPSNASA Predicts Nongreen Plants On Other Planets Green, yellow or even red-dominant plants may live on extra-solar planets. if astronomers were to look at the light given off by planets circling distant stars, they might predict that some planets have mostly non-green plants. "This work broadens our understanding of how life may be detected on Earth-like planets around other stars, while simultaneously improving our understanding of life on Earth," said Carl Pilcher, director of the NAI at NASA Ames. Kiang and her colleagues calculated what the stellar light would look like at the surface of Earth-like planets whose atmospheric chemistry is consistent with the different types of stars they orbit. By looking at the changes in that light through different atmospheres, researchers identified colors that would be most favorable for photosynthesis on other planets. Each planet will have different dominant colors for photosynthesis. The dominant photosynthesis might even be in the infrared.

POPSWhy your Car's Sat Nav Doesn't Like The Sun Presenting their findings at a conference on space weather in Washington DC, they said the solar burst was also strong enough to affect civil aviation navigation systems, but to a lesser degree than the GPS network, which uses a different satellite system. It may explain why systems unexpectedly lose the signal when they had perfect reception only moments before. There have been some incidents where drivers following their systems have caused accidents by taking a wrong turning or attempting to programme the device while driving.

POPSSmall asteroid risk is higher than estimated The chairman of this week's Planetary Defense Conference, William Ailor of the Aerospace Corp., a nonprofit established by Congress to support the Air Force's space defense program, said scientists generally agree that the risk to Earth from large asteroids is small. Researchers have identified more than 700 of these potential "planet killers" -- out of an estimated 1,000 -- and found that not one is on a collision course with Earth. "But with the smaller ones, the asteroids in the range, we're finding more and more," Ailor said yesterday. "They're hard to detect, and it's hard to predict where they are headed, but they can do a great deal of damage." NASA estimates that there are as many as 100,000 of the smaller asteroids in near-Earth orbit and that about 20 are "potentially hazardous."

POPSWe Could All Die Before Sunset! And you won't be safe on the other side of the planet. A massive shockwave, much like the aftershock of a nuclear explosion, will sweep across the globe. A wall of fire will roast every living thing on Earth -- well, except a few fish, that is. The Gamma Ray Burst will reset evolution. And if that isn't enough to kill you, there will be the soot. High up in the atmosphere, the loose atoms will bind up into nitrogen dioxide, a brown, filthy gas that will blanket the Sun. We'll have a massive nuclear winter and die a horrible climate disaster death. To make things worse, no one really knows how big the risks are. On the one hand, gamma ray bursts that damage our world are likely to happen once every 10 million years on average. That would mean our planet has survived many, many bursts in the prehistoric past. On the other hand, it's hard to predict when the next GRB will hit us. Could be in million years time. Could be tomorrow.

POPSEclipse Leaves Sky Gazers Over The Moon The colour of the Moon during an eclipse is not always the same, however. "It depends on the dust content of the Earth's atmosphere and perhaps the level of cloud," says Massey. "The red colour was certainly very intense and perhaps a little darker than I was expecting." Providing the local skies were clear, the deepest part of the eclipse was visible from all of Europe and Africa, and in Asia westward of central China. It was also visible in central and eastern North America and all of South America. Up to three lunar eclipses, including partial eclipses, can happen each year. The next total one will occur on 28 August 2007

POPSLunar Eclipse to Come Saturday It will take practically no effort to witness what promises to be a beautiful celestial event this weekend. Simply walk outside at sunset on Saturday and look to the east. Viewers in Europe, Africa, western Asia and part of Antarctica are in position to watch the entire eclipse. In the Americas, the eclipse will be underway by the time the moon rises, according to NASA scientists. The full eclipse ends at 6:57 p.m. EST. After that, the moon will slowly shed its reddish cloak and turn sparklingly bright — provided there are no Earthly clouds in the way to block the view.Parts of the eclipse, the first of two that will occur this year, will be visible on every continent, said Fred Espenak, with NASA's Goddard Space Flight Center in Greenbelt, Md.
