Galaxies have long been viewed as star factories, with more gas equating to more stars. However, a recent study challenges this notion, highlighting the crucial role of the location of hydrogen gas in star formation. The WALLABY survey, conducted with the ASKAP telescope in Western Australia, is shedding light on the distribution of atomic hydrogen in galaxies. Contrary to previous beliefs, the research indicates that the amount of star formation is more dependent on the gas within the stellar disk rather than in the outer regions. This discovery helps unravel the mystery of why some gas-rich galaxies produce few stars, as much of their gas remains unused in the outskirts. By examining around 1,000 galaxies, the study reveals a significant correlation between star formation and the presence of hydrogen within the stellar disk. This large-scale analysis emphasizes the importance of focusing not just on the total gas content of a galaxy, but on where this crucial ingredient is positioned for star-forming processes. Ultimately, by zooming in on the specific location of hydrogen gas, astronomers are gaining valuable insights into the complex mechanisms driving star formation in galaxies.
