In 2023, the activity of this black hole increased significantly, associated with a prolonged increase in low-energy X-rays that resulted in new radio flares, according to Gazeta.ru. By April 2023 ...

Now, this same black hole is once again captivating scientists with an extraordinary gamma-ray flare that’s emitted photons hundreds of billions of times more powerful than visible light.

When Sgr A* feeds on this material, it emits X-ray flares that propagate outwards in all directions. These flares interact with molecular clouds—gas clouds where stars form—in our galaxy's ...

Researchers have made a potentially crucial breakthrough in solar science that could help predict solar flares with greater ...

The blue circles represent solar flares: bursts of high-energy radiation of which STIX detects the X-rays. Flares are sent out by the sun when energy stored in "twisted" magnetic fields (usually ...

We present a detailed Fermi-LAT analysis to investigate the variability and spectral behaviors of 3C 279 during the γ-ray flares in 2018. In this work, we analyzed the γ-ray spectra and found that the ...

In addition to UV rays, heat can also trigger rosacea flare-ups. Because of this, it is best to avoid hot environments, such as sunbathing, saunas, or hot showers. People can also keep a cool ...
