Mars-Directed Coronal Mass Ejection Erupts From the Sun
NASA’s STEREO-A and ESA/NASA’s SOHO spacecraft detected a coronal mass ejection, or CME, leaving the Sun on April 17 at 12:36 p.m. EDT. This CME…

Rain is a common phenomenon on Earth. There is a similar phenomenon on the Sun, called coronal rain. It is related to the coronal heating…
The longest corridor in ESA’s largest establishment was turned into a test site for one of the Agency’s most ambitious future missions, Proba-3. The two…
Magnetic reconnection refers to the reconfiguration of magnetic field geometry. It plays an elemental role in the rapid release of magnetic energy and its conversion…
Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for the future of…
Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active…
An international team of researchers led by ETH Zurich has reconstructed solar activity back to the year 969 using measurements of radioactive carbon in tree…
When NASA’s Parker Solar Probe sent back the first observations from its voyage to the Sun, scientists found signs of a wild ocean of currents…
During Parker Solar Probe’s seventh swing by the Sun, culminating in its closest solar approach, or perihelion, on January 17, 2021, celestial geometry posed a…
The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the…
About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost…
For decades after its discovery, observers could only see the solar chromosphere for a few fleeting moments: during a total solar eclipse, when a bright…
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the…
What happens when the Solar System’s No. 1 source of violent energy interferes with spacecraft communication? Name? Solar Orbiter, or ‘Solo’ as the mission control…
A theory as to why the Sun’s outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for…
Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar…
NASA’s images of the Sun’s dynamic and dazzling beauty have captivated the attention of millions. In 2021, the US Postal Service is showcasing the Sun’s…
A secret behind the workings of sunquakes – seismic activity on the Sun during solar flares – might be hidden beneath the solar surface. These…
