Sun spots are relatively cooler spots on the Sun’s surface. Their number waxes and wanes in cycles that last 11 years approximately. We are currently at the minimum of one such cycle. Amidst claims that the Sun would “go silent” and not give out sunspots for an extended period, a group from IISER Kolkata has shown that the next sunspot cycle has begun and the Sun has indeed spoken. Their results were published in Research Notes of the American Astronomical Society.

Amidst claims that the Sun would “go silent” and not give out sunspots for an extended period, a group from IISER Kolkata has shown that the next sunspot cycle has begun and the Sun has indeed spoken. Their results were published in Research Notes of the American Astronomical Society. From our safe distance of about 148 million km, the Sun appears to be sedate and constant. However, huge solar flares and coronal mass ejections spew material from its surface into oute
