Latest Stellar magnetic field Stories
The presence of an atmosphere - among many other factors - is vital for the evolution of life as we know it on a planet. However, this seemingly simple requirement is bathed in a multitude of variables that can affect its creation and existence.
Whilst the most powerful earthquake since records began hit Japan in 2011, triggering a massive tsunami which devastated much of the country, space scientists involved in one of the 'brightest' international Sun missions continued working tirelessly at the Institute of Space and Astronautical Science in Sagamihara, Japan, to capture new data from our turbulent star.
A team of scientists has created an "MRI" of the Sun's interior plasma motions, shedding light on how it transfers heat from its deep interior to its surface.
On June 7, 2011, Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk.
For a thrilling eight minutes, NASA researchers will soon get a peek at one of the sun's most mysterious regions, where temperatures fluctuate from tens of thousands of degrees Fahrenheit to several million, and solar flares and coronal mass ejections originate -- potentially threatening spacecraft, Earth-based communications and the lives of explorers in space.
A team of researchers from University College London (UCL) has used data from the Hinode spacecraft, revealing new details of the formation of an immense magnetic structure that erupted to produce a CME on the December 7th 2007.
Solar wind generated by the sun is probably driven by a process involving powerful magnetic fields, according to a new study led by UCL researchers based on the latest observations from the Hinode satellite.
The mystery of why temperatures in the sun's outer atmosphere are higher than near the sun's surface may have been solved by Japan's Hinode satellite. James Klimchuk, an astrophysicist at NASA's Goddard Space Flight Center's Solar Physics Laboratory, says new observations by that satellite have revealed why temperatures in the solar corona, the sun's outer atmosphere, soar to several million degrees Kelvin -- much higher than temperatures nearer the sun's surface. The answer is nanoflares --...
Astronomy & Astrophysics is publishing the first detection of a magnetic field on the star Vega, one of the brightest stars in the sky.
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse.
Sunspot -- A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 Kelvin, the contrast with the surrounding material at some 6000 Kelvin leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc. History Apparent references...
