Powerful magnetic waves have been confirmed for the first time as major players in the process that makes the sun's atmosphere strangely hundreds of times hotter than its already superhot surface. The magnetic waves — called Alfven waves — can carry enough energy from the sun's active surface to heat its atmosphere, or corona. picked by AutumnLotus 8 months ago

A plethora of latest results from the Hinode solar observatory contains a wealth of new discoveries. This includes the discovery of a source of the slow solar wind and the observation of a superhot micro flare. picked by AutumnLotus 5 months ago

A new study reveals solar flares cause seismic waves to ripple across the sun's surface. The findings will help scientists study other stars. picked by AutumnLotus 4 months ago

Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. picked by AutumnLotus 9 months ago

The scientists lead by Dr. Carsten Hucho found a way to move smallest possible magnetic entities – so-called flux quanta – with the help of acoustic waves. Their results may open new ways to process data. picked by AutumnLotus 1 year ago

Mysterious waves that help transport the sun's energy out into space have been detected by scientists for the first time. picked by AutumnLotus 1 year ago

A $205 million upgrade will allow a laser-wielding observatory to monitor tens of thousands of galaxies for mysterious gravitational waves. Leading investigators are confident that the Advanced LIGO (Laser Interferometer Gravitational-wave Observatories) Project will be able for the first time to detect gravitational waves from neutron stars and black holes, as predicted by Einstein's theory of ge... read full post picked by AutumnLotus 5 months ago

If compasses were around a million years ago, they would not have pointed toward North. That's because the Earth's magnetic field likely underwent a reversal 800,000 years ago. picked by AutumnLotus 1 year ago

Images of a tsunami blasting its way through the sun's lower atmosphere have been taken for the first time.

NASA's twin STEREO spacecraft captured one of the massive solar waves in action May 19, 2007, as it moved through four layers of the solar atmosphere. picked by AutumnLotus 5 months ago

So how have these rocks hung onto their magnetic directions and what do they tell us about Mars? Strangely, the answer to these questions might be sitting here on Earth. picked by AutumnLotus 1 year ago

With some parts of Europe currently in the middle of a heat wave, it seems it's not only people who suffer from the soaring temperatures. picked by AutumnLotus 1 year ago

There are many interactions between the Sun and the Earth but one of the most dynamic events is a ‘substorm’ - an explosive reshaping of the Earth’s outer magnetic field.

Astrophysicists are having a heated debate over the wave structure of the Sun’s Corona - a debate which may one day influence solar weather forecasting and the theory behind fusion reactors. The Sun’s core is about 6000 degrees C, but its outer layer, the Corona, which is filled with a strong magnetic field, is 200 to 300 times hotter. picked by AutumnLotus 6 months ago

The planet Mercury's magnetic field appears to be strong enough to fend off the harsh solar wind from most of its surface, according to data gathered in part by a University of Michigan instrument onboard NASA's MESSENGER spacecraft. picked by AutumnLotus 7 months ago

Oxygen is constantly leaking out of Earth’s atmosphere and into space. Now, ESA’s formation-flying quartet of satellites, Cluster, has discovered the physical mechanism that is driving the escape. It turns out that the Earth’s own magnetic field is accelerating the oxygen away. picked by AutumnLotus 4 days ago

Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one “hotspot” in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. picked by AutumnLotus 9 months ago

University of Arizona astronomers have pinpointed the origin of powerful bursts from nature's most magnetic objects. The bursts are from "magnetars," some of the most enigmatic objects in the universe. picked by AutumnLotus 11 months ago

The Atlanta Hawks and Miami Heat must replay the final 51.9 seconds of their game last month because the NBA said the official scorer ruled incorrectly that Shaquille O'Neal fouled out. This will be the first time since 1982 the league has sent teams back on the court for a replay. picked by sholom22 8 months ago

Recently, researchers from the Hahn-Meitner-Institute (HMI) in Berlin in cooperation with University of Applied Sciences in Berlin have succeeded, for the first time, in a direct, three-dimensional visualisation of magnetic fields inside solid, non-transparent materials. picked by AutumnLotus 5 months ago

The first global map of magnetic peculiarities - or anomalies - on Earth has been assembled by an international team of researchers. Scientists hope to use the map to learn more about the geological composition of our planet. picked by 2manyusernames 10 months ago
