		Giant Breach in Earth's Magnetic Field Discovered NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to exist. The size of the opening and the strange way it forms could overturn long-held ideas of space physics. + Read More + Listen to Story + en español

		Solar Flare Surprise Solar flares are supposed to obliterate everything in their vicinity, yet one of the most powerful flares of the past 30 years has done just the opposite, emitting a beam of pure and unbroken hydrogen atoms. Researchers think this strange event could yield vital clues to the inner workings of solar flares. + Read More + Listen to Story + en español

		Discovered: Cosmic Rays from a Mysterious, Nearby Object An international team of researchers has discovered a puzzling surplus of high-energy electrons bombarding Earth from space. The source of these cosmic rays is unknown, but it must be close to the solar system and it could be made of dark matter. + Read More + Listen to Story + en español

		Solar Cycle Update: The Sun Shows Signs of Life A surge of new-cycle sunspots in October may signal the beginning of the end of the ongoing solar minimum. + Read More + Listen to Story + en español

		Magnetic Portals Connect Earth to the Sun Researchers have discovered 'magnetic portals' forming high above Earth that can briefly connect our planet to the Sun. Not only are the portals common, one space physicist contends they form twice as often as anyone had previously imagined. + Read More + Listen to Story + en español

		The Case of the Missing Gamma-ray Bursts Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing. + Read More + Listen to Story + en español

	Brief Mystery: What are Short Gamma-ray Bursts? A curiously short-lived type of gamma-ray burst has astronomers puzzled. Leading experts discuss the clues at today's Gamma-ray Burst Symposium in Huntsville, Alabama. + Read More + Listen to Story + en español

	Gamma-ray Bursts: The Mystery Continues More than four decades after they were discovered, gamma-ray bursts continue to mystify astrophysicists. Next week, experts from 25 countries will converge on Huntsville, Alabama, to discuss and debate clues to the biggest explosions since the Big Bang itself. + Read More + Listen to Story + en español

	How Round is the Sun? Scientists using NASA's RHESSI spacecraft have measured the roundness of the sun with unprecedented precision, and they find that it is not a perfect sphere. During years of high solar activity the sun develops a thin "cantaloupe skin" that significantly increases its apparent oblateness. + Read More + Listen to Story + en español
