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 ...
In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s, a temperature of ~ 100 kilokelvin and a composition that is a close match to the corona. By contrast, the fast solar wind has a typical velocity of 750 km/s , a temperature of 800 kilokelvin [ citation needed ] and it nearly matches the composition of the ...
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. [1] [2]
Earth has a new “mini-moon” after an asteroid has joined our orbit.. The object, known as 2024 PT5, has been chasing after us for years. Now, it has become close enough to be pulled in by our ...
The moon will appear to move in front of the sun beginning at 2:07 p.m. on April 8 in Rochester, New York. The window of totality is just 3 minutes and 38 seconds, with variance for location, and ...

An asteroid the size of a small truck will pass by Earth tonight, making one of the closest approaches to the planet ever recorded. Asteroid 2023 BU will zoom over the southern tip of South ...
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.
