Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
An example of space weather: Aurora australis in the Earth's atmosphere observed by Space Shuttle Discovery, May 1991. Space weather is the environmental condition within the Solar System, including the solar wind. It is studied especially surrounding the Earth, including conditions from the magnetosphere to the ionosphere and thermosphere.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere.Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena.
Just over a year ago, a space rock hurtled through the Martian atmosphere, broke apart, and slammed into the red desert. NASA just revealed footage of the new impact craters on Sept. 19, as well ...
The Sun's luminosity will have increased by 35–40%, causing all water currently present in lakes and oceans to evaporate, if it had not done so earlier. The greenhouse effect caused by the massive, water-rich atmosphere will result in Earth's surface temperature rising to 1,400 K (1,130 °C; 2,060 °F), which is hot enough to melt some ...
The U.S. Space Force is tracking debris in space after a satellite manufactured by Boeing exploded earlier this week, the satellite's operator said.. The Intelsat 33e satellite, which was launched ...
A space rocket engine exploded, sending plumes of fire and smoke into the sky during a failed test at a facility in Japan. The Epsilon S engine of the Japan Aerospace Exploration Agency blew up at ...
