The three-day May 1921 geomagnetic storm, also known as the New York Railroad Storm, was caused by the impact of an extraordinarily powerful coronal mass ejection on Earth's magnetosphere. It occurred on 13–15 May as part of solar cycle 15 , and was the most intense geomagnetic storm of the 20th century.

English: Follow a coronal mass ejection as is passes Venus then Earth, and explore how the sun drives Earth's winds and oceans. Other languages Čeština: Sledování výronu koronální hmoty ze sluneční koróny , který prolétá kolem Venuše a dále naší planety Země a ukazuje, jak tímto způsobem Slunce ovlivňuje pozemskou ...
In planetary geology, the term "ejecta" includes debris ejected during the formation of an impact crater. When an object massive enough hits another object with enough force, it creates a shockwave that spreads out from the impact. The object breaks and excavates into the ground and rock, at the same time spraying material known as impact ejecta.
In June 2013, a joint venture from researchers at Lloyd's of London and Atmospheric and Environmental Research (AER) in the US used data from the Carrington Event to estimate the cost of a similar event in the present to the US alone at US$600 billion to $2.6 trillion (equivalent to $774 billion to $3.35 trillion in 2023 [31]), [3] which, at ...
Stellar wind from a star cluster, Westerlund 2 pushes away surrounding gas and dust, creating shock wavesthat serve as the birthplace for new young stars. Image by the Hubble Space Telescope's Wide Field Camera 3. Stellar mass loss is a phenomenon observed in stars by which stars lose some mass over their lives.
The first time a commercially developed vehicle has carried Americans into space. And - the mission marks the first spaceflight of NASA astronauts from U.S. soil in nine years. After a farewell by ...
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 ...
