Scientists Discover Gigantic Solar Rossby Waves on the Sun
A team of scientists led by the Max Planck Institute for Solar System Research and the University of Göttingen has discovered gigantic swirls on the…
Physicists Discover Previously Undetected Energy in the Sun’s Coronal Loops
A team of physicists, including NJIT’s Gregory Fleishman, has discovered previously undetected energy in the Sun’s coronal loops. The Sun’s corona, invisible to the human…
Astronomers Predict What Will Happen When Our Sun Dies
Scientists agree the sun will die in approximately 10 billion years, but they weren’t sure what would happen next…until now. A team of international astronomers,…
SDO Views Our Sun In Three Different Wavelengths
From March 20-23, 2018, NASA’s Solar Dynamics Observatory captured three sequences of our Sun in three different extreme ultraviolet wavelengths. The resulting images illustrate how…
NASA Satellites Recreate Solar CME Eruption in 3D
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…
Physicists Solve 70-Year-Old Magnetic Wave Mystery
Scientists at Queen’s University Belfast have led an international team to the ground-breaking discovery that magnetic waves crashing through the Sun may be key to…
Space Weather Satellite Set to Go Where No Mission Has Gone Before
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…
Astronomers Reveal How a Magnetic Cage Stopped a Solar Eruption
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…
New Simulations of Magnetic Reconnection in the Sun
The Sun glows with a surface temperature of about 5500 degrees Celsius. On the other hand its hot outer layer, the corona, has a temperature…
Scientists Reveal How Much Dimmer the Sun Will Be By Mid-Century
The Sun might emit less radiation by mid-century, giving planet Earth a chance to warm a bit more slowly but not halt the trend of…
NASA’s Solar Dynamics Observatory Detects Solar Flare Pulses at Sun and Earth
When our Sun erupts with giant explosions — such as bursts of radiation called solar flares — we know they can affect space throughout the…
From Hot to Hottest, SDO Shows the Sun from Its Surface to Its Upper Atmosphere
This sequence of images from the Solar Dynamics Observatory shows the Sun from its surface to its upper atmosphere all taken at about the same…
Parker Solar Probe Will Fly Directly Through the Sun’s Atmosphere
Next Summer NASA will launch the Parker Solar Probe, a spacecraft that will get closer to the Sun than any other in human history. Parker…
Astronomers Detail the Nature of Solar Brightness Variations
For the first time, researchers reconstruct and detail the two phenomena that are responsible for the fluctuation of brightness in our sun. The Sun shines…
Scientists Watch the Sun Stop Its Own Solar Eruption
A team of astronomers watch as a failed solar eruption occurs on the surface of the Sun, leaving astronomers with a wealth of data captured…
