India, Oct. 12 -- The Government of India has issued a release:
Researchers have probed the mystery of why the poles of the Sun shine much brighter than the rest of the solar disk when mapped at certain specific microwave and radio frequencies.
The study could provide valuable insights into the magnetic field and temperature conditions in the Sun's polar atmosphere.
The Sun's polar regions play an important role in the evolution of its magnetic field and the generation of the solar wind. However, despite decades of observations, the cause of microwave polar brightening, the enhanced radio emission seen near the Sun's poles, has remained unclear.
Microwave polar brightening appears as an increase in radio brightness near the Sun's poles....
