Plasma tendrils erupting from near the sun’s surface might transfer energy to the corona in conjunction with magnetic field realignments ( SN: 12/7/19, p. Theories suggest the sun’s magnetic field somehow shifts solar energy to the corona, more than 2,000 kilometers above the sun’s surface. We still don’t know how the corona, the sun’s outer atmosphere, reaches such extreme temperatures. Some observers will seek to determine … the nature of the heating mechanism and the possible role of magnetic fields in keeping hot regions separated from cool ones. The temperature of the main body of the sun is about 6,000° Celsius, but the temperature in the corona goes up to millions of degrees. This year’s eclipse an important opportunity for observation….

Operating in the frequency range 70–300 MHz, the main scientific goals of the MWA are to detect neutral atomic Hydrogen emission from the cosmological Epoch of Reionization (EoR), to study the sun, the heliosphere, the Earth’s ionosphere, and radio transient phenomena, as well as map the extragalactic radio sky.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.
