Death by black hole: Astronomers spot flare from “spaghettification” of star

#1

From Ars Technica:
"It's a popular misconception that black holes behave like cosmic vacuum cleaners, ravenously sucking up any matter in their surroundings. In reality, only stuff that passes beyond the event horizon—including light—is swallowed up and can't escape, although black holes are also messy eaters. That means that part of an object's matter is actually ejected out in a powerful jet."

Probably an overly dramatic article, but there is a pointer to the Monthly Notices of the Royal Astronomical Society, 2020.
