![]() Helsinki (AFP) Sept 28, 2010 The Northern Lights have petered out during the second half of this decade, becoming rarer than at any other time in more than a century, the Finnish Meteorological Institute said Tuesday. The Northern Lights, or aurora borealis, generally follow an 11-year "solar cycle", in which the frequency of the phenomena rises to a maximum and then tapers off into a minimum and then repeats the cycle. "The solar minimum was officially in 2008, but this minimum has been going on and on and on," researcher ... read more |

Cassini Gazes At Veiled Titan![]() NASA's Cassini spacecraft will swing high over Saturn's moon Titan on Friday, Sept. 24, taking a long, sustained look at the hazy moon. At closest approach, Cassini will fly within 8,175 kilometers (5,080 miles) above the hazy moon's surface. This flyby is the first in a series of high-altitude Titan flybys for Cassini over the next year and a half. Cassini's composite infrared spect ... more Primordial Magnetic Fields Discovered Across The Universe ![]() Scientists from the California Institute of Technology and UCLA have discovered evidence of "universal ubiquitous magnetic fields" that have permeated deep space between galaxies since the time of the Big Bang. Caltech physicist Shin'ichiro Ando and Alexander Kusenko, a professor of physics and astronomy at UCLA, report the discovery in a paper to be published in an upcoming issue of Astro ... more Breaking Waves In The Stellar Lagoon ![]() A spectacular new NASA/ESA Hubble Space Telescope image reveals the heart of the Lagoon Nebula. Seen as a massive cloud of glowing dust and gas, bombarded by the energetic radiation of new stars, this placid name hides a dramatic reality.

![]() Tel Aviv, Israel (SPX) Sep 23, 2010 Titan, one of Saturn's moons, is the only moon in the solar system with an atmosphere - ten times denser than the atmosphere of Earth. Five years ago, the Cassini-Huygens mission to Saturn, a collaboration between the European Space Agency and NASA, sent a probe through Titan's atmosphere, revealing that Titan is home to a landscape that includes hills, valleys and most notably lakes. A researcher involved with the mission, Prof. Akiva Bar-Nun of Tel Aviv University's Department of Geophysics and ... read more |
