NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before. The animation shows the strength of the turbulent motions of the Sun’s inner layers … Read more
NASA’s Solar Dynamics Observatory captured these images of the solar flare on May 14, 2024 — as seen in the bright flash on the right side. These images show a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in royal blue and gold. This flare shows … Read more
Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the … Read more
“NASA’s growing heliophysics fleet is well suited to continue to investigate the source regions of these radio bursts,” said Natchimuthuk Gopalswamy, a heliophysicist and solar radio researcher at NASA’s Goddard Space Flight Center. “For example, the Solar Dynamics Observatory continually monitors the Sun’s active regions, which likely give rise to this phenomenon.” Source link
Sunspots are the dark patches on the Sun’s surface due to the star’s magnetic field. (Image: NASA) NASA’s new look at Sunspots: For years, Sun has been an object of fascination for scientists. Its study has only been boosted by NASA’s massive fleet of spacecrafts that allow astronomers to take a closer look at the … Read more
