...establishes that there are two symmetric arms in the inner part of the galaxy that branch off into four - answering a question that astrophysicists have grappled with for 50 years. (According to Pohl, our solar system is located near one of the branching-off points, about 28,000 light-years - or 168 quadrillion miles - from the galactic center...
...Milky Way. Pohl created his map using a kinetic model of the galaxy's gas flow, which was developed by Peter Engelmeier of the University of Zurich and Nicolai Bissantz of Ruhr University in Bochum, Germany, based on infrared data collected by a NASA satellite. Unlike visible light, infrared light penetrates dust clouds, so it provided Engelmeier and Bissantz with more precise measurements, in turn allowing Pohl to produce a more accurate, if not perfect, map. "Our method works over much of the Milky Way but not everywhere," he says...
...will be particularly useful to a research group in France that has been studying dark matter, which, as Reid's team has established, the Milky Way has a lot more of than previous studies had revealed. Dark matter, so called because it gives off little or no light, is one of the most abundant elements in the universe (it constitutes 23% of the universe's total density, whereas normal atoms make up only 4.6%), but because of its relatively recent discovery and our inability so far to gather direct evidence of its existence, it's also the least understood. With...
...Israel’s defenders say the attacks are a legitimate response to Hamas’ rocket-fire, and a clear case of self-defense. Anyone with a political memory longer than three weeks, however, knows how utterly hollow this statement is in light of the months-long blockade of Gaza. Israeli blockades of fuel, electricity, and food supplies from Gaza, which have been in place for well over a year, have drastically affected homes, businesses and hospitals in a region where 90 percent of the population lives below the poverty line, the most devastating effects of which are seen...
...A.N.C. will face its most formidable array of opposition parties to date. It is a development that would undoubtedly please Suzman. Even so, her passing - and the memory of her lifelong struggle as peaceful objector - casts all of today's South African politicians in a less than flattering light. Even faced with a stronger opposition, few doubt that the next South African president will be Jacob Zuma, the A.N.C. president, and a man who has been tried and acquitted of rape and has faced persistent allegations of corruption. Would he do any better than Mbeki, I asked? Unlikely, thought Suzman...
