NASA's Parker Solar Probe spotted 'stealth' outburst on the sun

Coronal mass ejections aren't known for being subtle: Each such event can fling huge amounts of the soup of charged particles called plasma off the sun and out into the solar system.

The report here wraps up with, "Within our solar system, coronal mass ejections are important because they can interfere with communications and navigation satellites orbiting Earth. And the farther astronauts venture from Earth, the more vulnerable they will be to the potential health impacts of such blasts. That's when learning to see coronal mass ejections we currently miss would become particularly important. Such phenomena are also intriguing because our sun is a star like any other. Scientists have spotted coronal mass ejections produced by other stars, but they'll never be able to see all such distant events. "This is another class that definitely can't be seen on other stars," Korreck said. "Is there a way that we can do this with Parker [Solar Probe] to better understand what's going on in other star systems?"

Our Sun is not so similar to other stars. Quite a number are rapid rotators that exhibit large flares and likely very large CME events too. Presently the Sun rotates about 2 km/s at the equator, other stars like T Tauri or many red dwarfs, rotate fast in the area of 10-20 km/s. The Sun, 4 billion years ago was spinning some 16+ km/s. Anticipate much more energetic CME events and flares at other stars. Kepler mission did document for quite a number of stars Kepler examined. This is a problem when searching for Earth 2.0 among the more than 4,000 exoplanets documented now. The Extrasolar Planets Encyclopaedia

Host star spin rates, CME events, and flaring. Fortunate for life on Earth today, our Sun is much more quite than many other stars.
