Summary

Story summary

Astronomers Lena Murchikova and Mark Gorski reported a wind from Sagittarius A* that creates a carbon-monoxide-free void near the black hole, observed with Chile’s Atacama telescope; processing of 100 hours of data made gas 100 times fainter and sharpened the image 80 times.
The study lasted five years.
Rebecca Diesing said the finding shows Sagittarius A* behaves like black holes in galaxies, unlike earlier X-ray and gamma-ray work that saw wind signatures from black hole.
