Solar flares can be very dangerous for power grids, satellites, even mobile phones. How dangerous a flare can be depends on how powerful it is. If timely warnings are received by NASA and other space agencies, the impact on Earth and humanity can be minimized. Now, NASA has found a solution. Yes, NASA has said it can predict solar flares. Scientists can now predict when and where the next solar flare may occur. The main role is that of the sun “flashes”.
In particular, solar flares are powerful bursts of energy. As per NASA, solar flares are the largest explosive events in our solar system and are observed as bright regions on the Sun and can last from minutes to hours. Flares and solar flares can disrupt radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
“Using data from NASA’s Solar Dynamics Observatory, or SDO, researchers at Northwest Research Associates, or NWRA, identified tiny signals in the upper layers of the solar atmosphere, the corona, that indicate I can help with which regions are available. the sun Solar flares are more likely to be produced—energetic bursts of light and particles ejected from them the sun” NASA said.
They found that above the regions that are about to ignite, the corona produces small-scale flashes – like tiny flashes before a big firework. This information may eventually help improve flare and location predictions. Weather Storms – Disruptive conditions in space caused by solar activity.
Scientists have previously studied how activity in the lower layers of the Sun’s atmosphere — such as the photosphere and chromosphere — can signal flare-up activity in active regions, often known as groups of sunspots or sunspots. The surface is marked by strong magnetic fields. are darker and cooler than their surroundings.
For their research, the scientists used a newly created image database of the Sun’s active regions acquired by the SDO. The publicly available resource, detailed in a companion paper also in The Astrophysical Journal, combines eight years of images of active regions in ultraviolet and ultra-ultraviolet light. According to NASA, led by Karin Disauer and engineered by Eric L. Wagner, the NWRA team’s new database makes it easier for scientists to use Atmospheric Imaging Assembly (AIA) data at SDO for larger statistical studies.
The NWRA team studied a large sample of active areas from the database using statistical methods developed by team member Graham Barnes. The analysis revealed that each flare was preceded by small flashes in the corona. These and other new insights will give researchers a better understanding of the physics in these magnetically active regions, with the goal of developing new tools to predict solar flares.
