Combining imagery from three of Solar Orbiter’s remote sensing instruments – the Extreme Ultraviolet Imager (EUI), the Metis coronagraph, and Solar Orbiter’s Heliospheric Imager (SoloHI)…
This artist’s illustration depicts a coronal mass ejection, or CME, which involves a large-scale expulsion of material, and have frequently been observed on our Sun….
The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the…
Living near a star is risky business, and positioning a spacecraft near the Sun is a very good way to observe rapidly changing solar activity…
A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights…
A newly published study details how astronomers developed a model that simulates the evolution of coronal mass ejections. Our ever-changing sun continuously shoots solar material…
Scientists from NASA and the National Center for Atmospheric Research have shown that data from a ground-based instrument called K-Cor can give scientists early warning…
Engineers developed the model as part of its Space Weather Modeling Framework, which is the first “first principles” model to simulate CMEs including their magnetic…
New research details how a shockwave created by the driving force of a coronal mass ejection from the sun – struck the outermost radiation belt,…
New research examines what creates the magnetic bands on the Sun and how they influence solar cycles, revealing that the changes in the magnetic field…
A team of astronomers has discovered that coronal mass ejections accelerate and concentrate nanodust particles in the interplanetary medium, a conclusion derived from STEREO instruments…
This short NASA video highlights the differences between coronal mass ejections (CMEs) and solar flares. How do you tell the difference between a flare and…
In an effort to better understand coronal mass ejections and their potential effects on human technology, a newly published study takes a detailed look a…
A new ScienceCast video details an intense solar storm that narrowly missed Earth two years ago. If it had hit, researchers say, we could still…
Post has been updated to reflect another CME that was detected on August 21, 2013 at 1:24 am EDT….Scroll to the bottom of the page…
Using data from NASA’s Solar Dynamics Observatory and the Hinode spacecraft, researchers reveal that the Sun’s atmosphere has a magnetic field about ten times weaker…
As solar activity continues to build up toward what is known as solar maximum, NASA details the impacts of CME’s and space weather on Earth….
NASA’s Solar Dynamics Observatory captured an image of an M6.5 class flare yesterday, April 11, 2013. The flare was also associated with an Earth-directed coronal…
