It is a joint project between an international consortium of organisations to construct and operate a low-frequency radio array.These speeds are so high that the particles can escape the Sun’s gravity.Ībout Widefield Array (MWA) radio telescope: The corona’s temperature causes its particles to move at very high speeds. From it comes the solar wind that travels through our solar system. Yet the corona is hundreds of times hotter than the Sun’s surface. The corona is in the outer layer of the Sun’s atmosphere-far from its surface. Astronomers have been trying to solve this mystery for a long time. The corona’s high temperatures are a bit of a mystery. This low density makes the corona much less bright than the surface of the Sun. The corona is about 10 million times less dense than the Sun’s surface. However, the corona can be viewed during a total solar eclipse.

That makes it difficult to see without using special instruments. The corona is usually hidden by the bright light of the Sun’s surface. The Sun’s corona is the outermost part of the Sun’s atmosphere. Researchers believe that these explosions could indeed be heating up the corona. These observations are the strongest evidence till date that the tiny magnetic explosions, originally referred to as ‘ nanoflares’ by eminent American solar astrophysicist Eugene Parker.

The radio lights or signals under study result from beams of electrons accelerated in the aftermath of a magnetic explosion on the Sun. The data was collected with the help of the Murchison Widefield Array (MWA) radio telescope. Sun’s Coronaįor Prelims and Mains: Corona- location, features, effects.Ĭontext: Scientists have recently discovered tiny flashes of radio light emanating from all over the Sun, which they say could help in explaining the long-pending coronal heating problem. Topics Covered: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc.
