Massive binary star system may be feeding the Milky Way’s central black hole
A string of small gas clouds near the Milky Way’s central black hole has puzzled astronomers for years.…

In light of that amazing view of the vicinity of Sagittarius A that's going around, I thought it might be topical to remind people of this magical visualisation from 2021:

ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core!
Although the galaxy’s central molecular zone (CMZ) has long been known to be filled with swirling dust and gas molecules cycling through formation and destruction, the mechanism that drives this process has remained elusive. Molecules serve as tracers for various processes in molecular clouds, with silicon monoxide (SiO) particularly useful in detecting the presence of shock waves.
Using ALMA’s high resolution and sensitivity to map distinct spectral lines within the molecular clouds at the center of the Milky Way, the team led by Kai Yang (Shanghai Jiao Tong University) has delineated a new type of long, narrow filamentary structure at a significantly finer scale. The dynamic interaction between this turbulent environment and the slim filaments produced as shocks ripple through provides a more complete view of the cyclical processes within the CMZ.
Yang’s team reports it remains unknown how these slim filaments initially arise, but shock processes emerge as a likely explanation.

Some shots of the Galactic Center I took up here in the gorgeous Berkshire Mountains. It was super fun putting all my new gadgets to work to get these shots! I’m super blown away at how much light this Sony 20mm f/1.8 G lens let’s in. These were shot at f/1.8, ISO 640, for 25 seconds. #photography #astrophotography #milkyway #galacticcenter #nightphotography #nightsky #stars #space #longexposure #night #galaxy #nature #cosmos #milkywaychasers #sonycamera #sonya7rv #sony20mmf18 #adobelightroom

How much uglier the Eagle Nebula looks in the Webb's infrared vision compared to the Hubble's optical vision might leave you with a bad taste in your mouth, so how about the Chandra's X-ray capture of the galactic center for a palate cleanser? 😍
