Polarized light reveals final fate of a star “spaghettified” by a black hole
From Ars Technica:
"When astronomers first observed a star that was shredded, or “spaghettified,” after approaching too close to a massive black hole in 2019, they determined that much of the star’s matter was launched outward in a powerful wind from the optical light emitted from the blast. Now, astronomers from the University of California, Berkeley (UCB) have analyzed the polarization of that light to determine that the cloud was likely spherically symmetric, adding further evidence for the presence of that powerful wind."
