Plasma eruptions from the Sun's surface — from small bursts to gigantic eruptions that can cause spectacular auroras on Earth — are all part of the same process and have the same underlying mechanism, a new study in Nature shows.

Why this matters: Electromagnetic radiation from the sun can cause interference with radio and satellite transmissions. The high-energy, charged particles from the sun's eruptions also can endanger astronauts in space (one of the challenges to traveling to places like Mars). Understanding the true nature of the plasma eruptions across the entire spectrum will potentially allow scientists to mitigate risks.

A closer look at the Sun: There are two very different types of hot gas eruptions from the Sun's blazingly hot surface: relatively small bursts of plasma (coronal jets) and huge clouds of plasma (coronal mass ejections) that explode off into space at very high speeds. Because the eruptions are on such vastly different scales, scientists thought they were driven by different processes.

Using 3d computer simulations, scientists from NASA's Goddard Space Center and Durham University in the UK were able to show that the Sun's eruptions are theoretically part of the same process. When large regions of dense, cool gas called filaments become unstable or stressed, they break through the magnetic field that suspends them above the Sun's surface and trigger small and large ejections.

Facebook boycott organizers share details on their Zuckerberg meeting

Facebook is in the midst of the largest ad boycott in its history, with nearly 1,000 brands having stopped paid advertising in July because they feel Facebook hasn't done enough to remove hate speech from its namesake app and Instagram.

Axios Re:Cap spoke with the boycott's four main organizers, who met on Tuesday with CEO Mark Zuckerberg and other top Facebook executives, to learn why they organized the boycott, what they took from the meeting, and what comes next.

Civil rights leaders blasted Facebook's top executives shortly after speaking with them on Tuesday, saying that the tech giant's leaders "failed to meet the moment" and were "more interested in having a dialogue than producing outcomes."

Why it matters: The likely fallout from the meeting is that the growing boycott of Facebook's advertising platform, which has reached nearly 1000 companies in less than a month, will extend longer than previously anticipated, deepening Facebook's public relations nightmare.

Steve Scalise PAC invites donors to fundraiser at Disney World

House Minority Whip Steve Scalise’s PAC is inviting lobbyists to attend a four-day “Summer Meeting” at Disney World's Polynesian Village in Florida, all but daring donors to swallow their concern about coronavirus and contribute $10,000 to his leadership PAC.

Why it matters: Scalise appears to be the first House lawmakers to host an in-person destination fundraiser since the severity of pandemic became clear. The invite for the “Summer Meeting” for the Scalise Leadership Fund, obtained by Axios, makes no mention of COVID-19.
