Legends are like the shifting sands of a desert — forever changing and hard to grasp. This Chinese legend of Houyi and Chang’e is no exception, and many different versions have been passed down. The Jade Emperor, the ruler of Heaven, had 10 unruly sons. One day, they transformed themselves into 10 suns, heartlessly scorching ...
In direct contradiction to the official forecast, a team of scientists led by the National Center for Atmospheric Research (NCAR) is predicting that Sunspot Cycle 25, which started this fall, could be one of the strongest since record-keeping began. In a new article published in Solar Physics, the research team predicts that Sunspot Cycle 25 ...
An orbiting instrument hints at how stored magnetic energy heats the solar atmosphere. A phenomenon first detected in the solar wind may help solve a long-standing mystery about the Sun: why the solar atmosphere is millions of degrees hotter than the surface. Images from the Earth-orbiting Interface Region Imaging Spectrograph, aka IRIS, and the Atmospheric Imaging Assembly, ...
On May 29, 2020, a family of sunspots — dark spots that freckle the face of the Sun, representing areas of complex magnetic fields — sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft ...
A new study led by the University of Hawai‘i (UH) at Mānoa has helped refine our understanding of the amount of hydrogen, helium, and other elements present in violent outbursts from the Sun and other types of solar “wind,” a stream of ionized atoms ejected from the Sun. Coronal mass ejections (CME) are giant plasma bursts that ...
Just released first images from the National Science Foundation’s Daniel K. Inouye Solar Telescope reveal unprecedented detail of the Sun’s surface and preview the world-class products to come from this preeminent 4-meter solar telescope. NSF’s Inouye Solar Telescope, on the summit of Haleakala, Maui, in Hawai‘i, will enable a new era of solar science and ...
A Queen’s University Belfast scientist has led an international team to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface. The findings could help to solve the mystery of how the corona of the Sun maintains its multi-million-degree temperatures. For more than 60 years, observations of ...
If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That’s how NASA’s Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade. Gamma-ray observations are not sensitive enough to clearly see the shape of the Moon’s disk or any surface features. Instead, Fermi’s Large ...
For five months in mid-2017, Emily Mason did the same thing every day. Arriving at her office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images of the Sun — all day, every day. “I probably looked through three or five years’ ...
ANU scientists have found that Earth is made of the same elements as the Sun, but it has less of the volatile elements such as hydrogen, helium, oxygen, and nitrogen. Lead author of the study, Dr. Haiyang Wang, said they made the best estimate of the composition of Earth and the Sun with the aim ...
