Latest Magnetosphere Stories
MESSENGER scientists have concluded that waves driven by the Kelvin-Helmholtz (KH) instability play a key role in driving Mercury's magnetosphere.
A NASA satellite yesterday captured spectacular images and video of a massive solar flare erupting from the eastern side of the Sun.
On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere.
Scientists have seen auroras dancing around above the giant ice planet Uranus by using the Hubble Space Telescope.
Venus is a rarity among planets - a world that does not internally generate a magnetic field. Despite the absence of a large protective magnetosphere, the near-Venus environment does exhibit a number of similarities with planets such as Earth.
Since the NASA / ESA Cassini-Huygens spacecraft arrived at Saturn in 2004, astronomers and space scientists have been able to study the ringed planet and its moons in great detail.
A trio of CubeSats that will study the effects of space weather on the Earth’s radiation belts and magnetic field are being prepared for launch. TRIO-CINEMA is a collaboration between UC Berkeley, Kyung Hee University and Imperial College London.
Venus, often referred to as Earth’s sister planet due to its similar size, gravity, and composition, has been discovered by astronomers to also have a type of space weather event that is commonly found on Earth: a hot flow anomaly or HFA.
Researchers from MIT report that they have used a massive computer simulation to explain a mysterious phenomenon detected by space probes.
Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Hannes Olof GÃ¶sta AlfvÃ©n (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in NorrkÃ¶ping, Sweden. AlfvÃ©n received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. AlfvÃ©n made many contributions to plasma physics, including theories describing the...
Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...
Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
