Massive Underground “Ghost Particle” Detector Finds Final Secret of Our Sun’s Fusion Cycle
A hyper-sensitive instrument, deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos (tiny particles pointing to the presence…
Studying the Sun From Far Away Like a Star to Understand Stellar Flares and Exoplanets
New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to…
Understanding the “Hydrogen Burning” Power of Our Sun – Success After More Than 80 Years
The Borexino collaboration, in which also scientists from TU Dresden are involved, has succeeded after more than 80 years in experimentally confirming the Bethe-Weizsäcker cycle….
Large Sunspot Predicted for Thanksgiving Using Helioseismology – “Listening” to Sound Waves From the Sun’s Interior
On November 18 scientists from the US National Science Foundation’s National Solar Observatory predicted the emergence of a new sunspot group just in time for…
NASA’s Solar Dynamics Observatory “Flaming Jack-o’-Lantern” Sun for Halloween
Active regions on the sun combined to look something like a jack-o-lantern’s face on October 8, 2014. The active regions appear brighter because those are…
Solar Cycle 25: The Sun Wakes Up
The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy,…
Artificial Intelligence Helps Understand the Evolution of Young Stars and Their Planets
University of Chicago scientists teach a neural net to find baby star flares. Like its human counterparts, a young star is cute but prone to…
Moon Photobombs NASA’s Solar Dynamics Observatory’s View of the Sun
On October 16, 2020, the Moon photobombed NASA’s Solar Dynamics Observatory’s view of the Sun. This apparent crossing in space, called a lunar transit, lasted…
A New Look at Sunspots is Helping NASA Understand Life Around Other Stars
NASA’s extensive fleet of spacecraft allows scientists to study the Sun extremely close-up – one of the agency’s spacecraft is even on its way to…
First Data From Solar Orbiter Released to the Public
ESA has released its first Solar Orbiter data to the scientific community and the wider public. The instruments contributing to this data release come from…
Global Maps of the Solar Corona Magnetic Field Created for the First Time
The Sun is a magnetized star. Its magnetic field is essentially three dimensional and it occupies all layers of the solar atmosphere. However, routine measurements…
Scientists Analyze Sunquakes: Can Ripples on the Sun Help Predict Solar Flares?
Scientists analyze sunquakes to pinpoint flare energy source, perhaps predict flare severity. Solar flares are violent explosions on the sun that fling out high-energy charged…
NASA IRIS Reports the First Ever Clear Images of Nanojets on the Sun
NASA’s IRIS Spots Nanojets: Shining Light On Heating the Solar Corona In a paper published today (September 21, 2020) in Nature Astronomy, researchers report the…
Solar Cycle 25 Has Begun. Experts From NASA and NOAA Explain What It Means
Solar Cycle 25 has begun. During a media event on Tuesday, experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed their analysis…
How NASA & Scientists Around the World Track the Solar Cycle
Understanding the Sun’s behavior is an important part of life in our solar system. Scientists use several indicators to track solar cycle progress. Credit: NASA’s…
Improved Solar Storm Forecasts for Earth With Help From the Public
New CME forecasting method shows value of including imaging cameras on future NASA missions. Solar storm analysis carried out by an army of citizen scientists…
Global Magnetic Field of the Solar Corona Mapped for the First Time
