Astronomers will unveil a “major result” on Tuesday (June 14) regarding the sun’s 11-year sunspot cycle.
The announcement will be made at a solar physics conference in New Mexico, according to an alert released today (June 10) by the American Astronomical Society. The discussion will begin at 1 p.m. EDT (1700 GMT).
Sunspots are blotches on the sun that appear dark because they are significantly cooler than the rest of the solar surface. While they look small from our vantage point on Earth, these enigmatic structures can be huge — up to 30,000 miles (48,280 kilometers) across, or as wide as the planet Neptune. Sunspots last for a few days or weeks before dissipating. [Photos: Sunspots on Earth’s Star]
