In addition to ubiquitous solar wind, the solar corona frequently expels large-scale magnetized plasma structures into the heliosphere. Such episodic expulsions of plasma from the Sun are called Coronal Mass Ejections (CMEs).
10 de may. de 2024 · Scientists at the National Oceanic and Atmospheric Administration Space Weather Prediction Center observed a cluster of sunspots on the surface of the sun this week. With them came solar flares...
24 de sept. de 2014 · Watch on. Three NASA observatories work together to help scientists track the journey of a massive coronal mass ejection, or CME, in July 2012. On July 23, 2012, a massive cloud of solar material erupted off the sun’s right side, zooming out into space.
2 de nov. de 2023 · In the five decades since that discovery, there have been five generations of coronagraphs, each with improved performance, enabling continued understanding of the phenomena, which became known as Coronal Mass Ejection (CME) events.
Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength. CMEs travel outward from the Sun at ...
10 de sept. de 2019 · In order to have a comprehensive view of the propagation and evolution of coronal mass ejections (CMEs) from the Sun to deep interplanetary space beyond 1 au, we carry out a kinematic analysis of seven CMEs in solar cycle 23.
21 de feb. de 2024 · Coronal mass ejections (CMEs) are clouds of energetic plasma and magnetic fields that are regularly launched from the Sun.
