A new study by NASA scientists focuses on sunspots, the “black spots” on the sun caused by the sun’s magnetic field. Although NASA has spacecraft that can observe sunspots closer, researchers study sunspots at low resolution as if they were trillions of miles away. The team will conduct simulated observations of distant stars to help them better understand the activity of stars and the life conditions of planets orbiting distant stars. Shin toriumi, the lead author of the new study and a scientist at the Institute of space and astronomical Sciences at the Japan Aerospace Research and development agency, said the team wanted to know what the sunspot region would look like if they couldn’t figure it out in the image. Researchers use the sun’s sun data, just as it comes from distant stars, to better connect the sun and stellar physics. Sunspots usually occur before solar flares, which are intense energy bursts on the surface of the sun. Monitoring sunspots is important because solar flares can affect life on earth and on the international space station or other spacecraft. The project’s researchers also believe that understanding the frequency of solar flares on a star other than the sun is key to understanding whether a planet orbiting the star has a chance to nurture life. < / P > < p > in this study, high-resolution solar data from the NASA Solar Dynamics Observatory and the JAXA / NASA Hinode joint mission were studied. By adding light and each image, scientists can convert high-resolution images into a single data point. Researchers were able to create a map of how sunspots change as they pass through the sun’s rotating surface. These graphs, called light curves, allow scientists to see sunspots on the sun from many light-years away. < / P > < p > in this study, a single sunspot was observed on the surface of the sun. The researchers found that the light curves were different when measured at different wavelengths. In visible light, a single sunspot in the center of the sun makes the sun appear darker. When a sunspot is on the edge of a star, it is actually brighter. The team also wants to know what caused the super flare on the sun. Global Tech
