The peaks are the days when gamma radiation was emitted by sunspots in high concentrations. |
Scientists are still figuring out the role of sunspots in space weather, but they do know that when a flare erupts, sunspots are often nearby. |
Note the white bands buried amid the black and gray sunspots, depicting the twin bands of the flare as it burst into view around the sunspots. |
The severe weather on Earth is likely related to sunspots and solar flares on the sun. |
The Sun spins once on its axis once every 25 days at its equator, carrying sunspots around. |
The topmost paper was a graph measuring gamma ray radiation from sunspots over the past few months. |
