In November this year, the northern lights were seen unusually far south, in locations like Italy and Texas. This was due to the effects of…
Space radiation poses a significant challenge to humanity’s ambitions in space exploration, particularly in missions to the Moon and Mars. This radiation, primarily from solar…
A solar eruption detected simultaneously at Earth, the Moon, and Mars emphasizes the need to prepare human exploration missions for the dangers of space radiation….
A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on…
In the early hours of Sunday, September 4, Solar Orbiter flew by Venus for a gravity-assist maneuver that alters the spacecraft’s orbit, which will get…
In the search for “potentially-habitable” extrasolar planets, one of the main things scientists look at is stellar activity. Whereas stars like our own, a G-type…
Astronomers spying on a stellar system located dozens of lightyears from Earth have, for the first time, observed a troubling fireworks show: A star, named…

A mass of solar material that erupted from the Sun on October 9, 2021, reached Earth on October 12. The Earth-directed coronal mass ejection, or…
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,…
