Two massive solar flares from the Sun disrupt radio signals across the US and other regions.
are powerful bursts of radiation that cannot harm humans on the ground but can disturb the atmosphere where GPS and communications signals travel.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However – when intense enough – they can disturb the atmosphere in the layer where GPS & communications signals travel.As per NASA, the previous solar flare happened on Friday, August 5, and peaked at 6:21 pm Eastern Time.
Solar activity follows an 11-year cycle, with high and low activity periods. The current cycle, known as Solar Cycle 25, began in December 2019 and is expected to peak in July 2025. Scientists use various instruments and satellites to monitor the Sun’s activity, such as NASA’s Solar Dynamics Observatory and NOAA’s Geostationary Operational Environmental Satellite system. By studying the Sun’s behavior, they hope to understand its impact on Earth and space better.

Powerful Sun Storm Disrupts Radio Transmissions in North AmericaA powerful sun storm has caused disruptions in radio transmissions across North America. This is the second X-flare unleashed by the sun in less than three days, and experts warn that more such activity may occur. The radiation from these flares interacts with particles in Earth's ionosphere, supercharging them and affecting radio and satellite signals passing through this region.

Two Stars Orbiting Each Other So Closely They Could Fit Inside the SunAstronomers have discovered a pair of star-like objects orbiting each other extremely quickly, with an entire ‘year’ lasting just 1.9 Earth hours. The system consists of one object which is definitely a small star, and another that straddles the boundary between star and planet. The two objects appear to be very close to each other, suggesting that their orbit has significantly shrunk over time. Understanding this process is crucial for unraveling the mysteries of solar system formation.
