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.
This causes their hold on their upper layers to weaken allowing small disturbances to blast large amounts of the outer layers into space. Events such as solar flares and coronal mass ejections are mere blips on the mass loss scale for low mass stars (like our sun). However, these same events cause catastrophic ejection of stellar material into ...
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 ...
A coronal mass ejection (CME) is a significant ejection of plasma mass from the Sun's corona into the heliosphere. CMEs are often associated with solar flares and other forms of solar activity , but a broadly accepted theoretical understanding of these relationships has not been established.

[20] [2] The martian ejecta blankets are categorized broadly into three groups based on the observed morphology identified by spacecraft data: [14] a. Layer ejecta pattern: the ejecta blanket seems have formed by fluidization process and composed of single or multiple partial or complete layers of sheet of materials surrounding the crater. [14]
Several days later, at 01:27 UT on March 13, a severe geomagnetic storm struck Earth. [4] [5] The storm began on Earth with extremely intense auroras at the poles. The aurora could be seen as far south as Texas and Florida. [6] As this occurred during the Cold War, some people worried that a nuclear first strike might be in progress. [6]
