A Glowing Plume Over Mount Etna

<<There is nothing particularly unusual about Mount Etna flinging lava, volcanic ash, or molten rocks into the air. The Italian volcano ranks as one the most active in Europe and has been in a state of eruption since 2011.
Yet even experienced Etna watchers have been wowed by the intensity of the volcano’s unrest in February 2021. Starting on February 16, Etna’s Southeast Crater produced a string of intense lava fountains that continued sporadically for nearly a week. Southeast Crater is one of four summit craters on the volcano and the youngest; it formed in 1971.
“The most recent novelty is that the last six eruptive paroxysms were among the most violent in the Southeast Crater's young history,” explained Marco Neri, a volcanologist with Italy's National Institute of Geophysics and Volcanology (INGV).
February 20-21 and February 22-23 brought particularly intense activity. At times, lava fountains soared as high as 1.5 kilometers, about 3 times the height of One World Trade Center, the tallest building in the United States. Columns of ash and small rock fragments (called lapilli) rose as high 10 kilometers in altitude. Long lava flows poured down Etna's eastern flank.
While the recent paroxysms have impressed geologists, they were not out of character for the restive volcano. Paroxysms of similar intensity have occurred at Mount Etna at least four times since 1989, and the volcano has produced roughly 250 paroxysms of various strengths since 1977, said Boris Behncke, also with INGV.
While ash temporarily closed the nearby airport and meant extra sweeping for many people in northern Sicily, the February paroxysms caused little serious damage or disruption. As long as the paroxysms remain at this intensity and lava comes from the summit rather than the sides of the volcano, the risks poses to surrounding communities are small.
But there is no guarantee that Etna will remain in its current eruptive stance forever. “Periods of intense activity are almost always followed by lateral eruptions that open up mouths on the flank of the volcano, at times at low elevations,” said Neri. “That means there is a concrete possibility that lava could directly affect an urbanized area, as has happened numerous times in the past.”
Lava from Etna has occasionally caused problems for surrounding communities. In 1669, lava overwhelmed part of Catania. In 1983, engineers used dynamite to divert lava away from homes. And in 1992, the army had to build an earthen wall to protect a village.>>
Stars over an Erupting Volcano
Stars above the volcano? Bet beings on planets around those stars don't even know about Earth and it's volcanos! Just saying! 
I had been searching for "guide astronomy", not "project pluto". Of course! (Plus, i only needed to scroll down my search results page a bit more and would have found Guide.)
