Scientists have uncovered an extraordinary phenomenon deep within our galaxy—massive, swirling ‘space tornadoes’ near the Milky Way's supermassive black hole. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, astronomers have obtained the most detailed images yet of these cosmic whirlwinds, which may play a crucial role in shaping the galactic environment.
A New Discovery in the Galactic Core
The study focused on a region called the Central Molecular Zone (CMZ), a turbulent area filled with dense clouds of dust and gas surrounding the Milky Way's supermassive black hole, Sagittarius A*. While these rotating structures had been observed before, ALMA’s powerful radio imaging provided a resolution 100 times sharper than previous studies, revealing previously unseen details.
One of the most surprising findings was the presence of long, thin filaments moving in a direction opposite to their surroundings. Lead researcher Kai Yang from Shanghai Jiao Tong University noted, “Unlike any objects we know, these filaments really surprised us.”
The Role of Space Tornadoes
These space tornadoes are more than just chaotic cosmic winds. They function as violent streams of gas that dissipate quickly and efficiently distribute material across the galaxy. The research team found that these whirlwinds likely disperse not only silicon monoxide, a compound that traces shock waves, but also complex organic molecules such as methanol, methyl cyanide, and cyanoacetylene.
This molecular distribution process could have significant implications for the chemical evolution of the Milky Way, potentially influencing star formation and the development of planetary systems.

What’s Next?
Further observations with ALMA will help scientists determine how widespread these filaments are and their exact role in the galaxy’s molecular cycle. The high sensitivity of ALMA was crucial in detecting these emissions, and future studies could reveal even more insights into the hidden mechanisms of our galaxy’s core.
This discovery adds to the growing understanding that the Milky Way is far more dynamic than once believed. As astronomers continue to probe the depths of space, these space tornadoes may prove to be key players in the grand cosmic dance of matter and energy.
