Hydrogen Abundant Stars Fewer | Science News

The universe’s star-making pace has slowed dramatically over the past 4.5 billion years, yet the key ingredient—neutral atomic hydrogen—has stayed stubbornly constant. Using China’s FAST radio telescope and a clever technique called spectral stacking, scientists detected this puzzling mismatch: plenty of gas, but far fewer stars. The mystery isn’t about running out of fuel, but why it’s harder to turn that gas into stars. Now astronomers suspect the problem lies in how gas flows and condenses within galaxies, not how much is available.
