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.”
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
