“Space tornadoes” are swirling near the supermassive black hole at the heart of our Milky Way galaxy, new telescope observations have revealed in unprecedented detail.
Astronomers recently zoomed in on the cosmic twisters using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. Although these rotating structures had been seen previously, the new observations with ALMA are 100 times sharper than the earlier views, the team reported in a new paper published in the journal Astronomy & Astrophysics.
The researchers began by pointing ALMA at a region of the galaxy known as the central molecular zone (CMZ), which surrounds our galaxy’s core supermassive black hole and is filled with seething clouds of dust and gas. The team wanted to uncover the mechanism driving the relentless motion of these clouds.
