Daniel K. Inouye Solar Telescope captures image of sunspots

The most powerful solar telescope in the world, the Daniel K. Inouye Solar Telescope in Hawaii, captured a detailed image of a cluster of sunspots using its Visible Tunable Filter (VTF). Scientists hope it will help predict solar storms. The telescope is not fully operational yet, but the image it captured during testing shows its potential. Sunspots are areas of intense magnetic activity that can trigger solar flares and coronal mass ejections with damaging effects on Earth.

Astronomers observe flares of light in the accretion disk around Sagittarius A* black hole

Astronomers have observed flares of light in the accretion disk orbiting the supermassive black hole Sagittarius A*, which is unique due to its shorter durations and varying brightness. This phenomenon provides valuable insights into the magnetic activity of black holes and can help test scientific theories, including Einstein's general theory of relativity.
