Solar Probe Finds Small Flares That May Help Heat the Corona #SpaceSaturday
The images that have come from ESA and NASA’s have been beautiful and astonishing. They’ve also brought new information on the dynamics of our closest start. Here’s more from Astronomy Now:
The ESA/NASA Solar Orbiter’s first images, unveiled 16 July, provide a spectacular new look at the Sun, including surprising views of small flare-like blazes dubbed “campfires” that may provide at least some of the energy powering the star’s million-degree corona….
While the new data do not yet resolve the issue, “our conjecture is these campfires … are related to changes in the Sun’s magnetic field, a process known as magnetic reconnection,” Müller said during a news briefing. “We believe that even though it’s the ‘quiet’ Sun, and there are only small scale magnetic fields, these filaments do get tangled and get under stress. And like rubber bands, they can eventually tear and then reconfigure into new configurations.”
