India, Dec. 7 -- Indian scientists have come up with the first physics-based prediction of the upcoming solar cycle - also called sunspot cycle - scheduled to start early in 2020. The prediction revealed how the sun will behave and the expected conditions in space over the next decade, which will help in strategically plan missions to space and in the upkeep of space-based technologies.

Every 11 years, the sun's magnetic field flips because the north and south poles switch places, which marks the beginning of a new solar cycle. The solar cycle affects the activity on the surface of the sun such as sunspots, which are caused by the sun's magnetic fields. When the magnetic field lines near sunspots tangle, cross, or reorganize, it can lead...
