Black Hole Radiation from Sun Threatens Earth – Latest Tech News
Scientists have observed a large dark hole on the surface of the Sun, emitting powerful streams of solar wind towards Earth. This transient black hole, known as a coronal hole, is larger than 60 Earths and has a width of approximately 800,000 kilometers. The formation of this giant coronal hole near the Sun’s equator was recorded on December 2, and it has been directly aimed at the Earth since December 4.
Coronal holes occur when the magnetic fields holding the Sun in place suddenly open, causing the sun’s upper surface to release solar wind. These holes appear as dark spots because they are cooler and less dense than the surrounding plasma, and are not visible unless viewed in ultraviolet light.
The radiation streams from coronal holes are known to be much faster than the normal solar wind, and they can trigger disruptions in Earth’s magnetic shield, leading to geomagnetic storms. However, the recent solar wind from this particular coronal hole has been less intense than expected, resulting in a weaker geomagnetic storm than initially predicted.
It is uncertain how long the black hole will remain in the Sun, but past coronal holes have lasted up to 27 days. Experts continue to monitor the situation and its potential impact on Earth’s magnetic field, as well as the possibility of stronger geomagnetic storms in the coming days.
