NASA’s Wind Mission Encounters ‘SLAMS’ Waves
By Klaus Schmidt | Space Fellowship As Earth moves around the sun, it travels surrounded by a giant bubble created by its own magnetic fields, called the magnetosphere. As the magnetosphere plows through space, it sets up a standing bow wave or bow shock, much like that in front of a moving ship. Just in front [...]

UOW | eScience A team led by the University of Warwick has pinpointed a new type of exceptionally powerful and long-lived cosmic explosion, prompting a theory that they arise in the violent death throes of a supergiant star. These explosions create powerful blasts of high energy gamma-rays, known as gamma-ray bursts, but while most bursts [...]

ANI NASA’s Cassini spacecraft has observed an ice cloud taking shape over Titan’s south pole, the latest sign that the change of seasons is setting off a cascade of radical changes in the atmosphere of Saturn’s largest moon. Made from an unknown ice, this type of cloud has long hung over Titan’s north pole, where it [...]

By RT Renowned British physicist Stephen Hawking warns human beings won’t survive “without escaping” from the “fragile” planet. His gloomy forecast is people will become extinct on Earth within current the millennium. Speaking at the Cedars-Sinai Medical Center in Los Angeles the 71-year-old scientist called for further exploration of space to guarantee the future of [...]

NewsTrack A new study led by two Indian researchers has claimed that space travel could increase the risk of colon cancer. An earlier study had shown that mice exposed to a type of high-energy radiation prevalent in space, called 56Fe radiation, had developed tumours in their intestines. A second study by the same group of [...]

By Mike Wall | Live Science The planet Mars lost most of its original atmosphere long ago when huge amounts of gas escaped into space, leaving only a wispy remnant behind, scientists say. NASA’s Mars rover Curiosity has revealed that a light variant of the gas argon is relatively depleted in Martian air, bolstering a [...]

ZeeNews The radiation environment near the Moon could be damaging to humans and electronics on future missions, it has been revealed. To characterize this potentially hazardous environment, the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) on board the Lunar Reconnaissance Orbiter mission, which orbits at 50 kilometers (31 miles) above the Moon’s surface, [...]

By Mihai Andrei | ZMEscience A magnetic solar ‘heartbeat’ beats deep down in the Sun’s interior, generating energy that leads to solar flares and sunspots. A solar flare is a large energy release in the form of a sudden brightening of the surface or the solar limb. The flare ejects clouds of electrons, ions, and atoms through the corona [...]

AP | The Japan News It is one of the cosmos’ most mysterious unsolved cases: dark matter. It is supposedly what holds the universe together. We cannot see it, but scientists are pretty sure it is out there. Led by a dogged, Nobel Prize-winning gumshoe who has spent 18 years on the case, scientists put [...]

Carnegie Institution | eScience Supernovae were always thought to occur in two main varieties. But a team of astronomers including Carnegie’s Wendy Freedman, Mark Phillips and Eric Persson is reporting the discovery of a new type of supernova called Type Iax. This research has been accepted for publication in The Astrophysical Journal. Previously, supernovae were divided [...]

By Stuart Clark | The Guardian The map of the oldest light in the universe shows intriguing deviations from expectations. Will these oddities be explained away or are we at the beginning of a revolution in cosmology? The map of the cosmic microwave background radiation revealed today by the European Space Agency’s Planck mission. Photograph: [...]

The Daily Galaxy RCW 120 is a galactic bubble that harbors a very large surprise. A surprise that’s at least eight times the mass of the sun. Nestled in the shell around this large bubble is an embryonic star that looks set to turn into one of the brightest stars in our Milky Way galaxy. The galactic bubble [...]
