False-color image of an all-sky HI (neutral hydrogen) survey. The bright band across the center represents the plane of our Milky Way galaxy, showing vast clouds of hydrogen gas tens to hundreds of light-years across. These structures are shaped by stellar activity within the galactic disk. The image is based on radio wave emissions from hydrogen atoms at a wavelength of 21 centimeters.

Star birth is down 60% — the universe&#8217;s hydrogen supply is mostly intact
A survey of 2.5 million galaxies using FAST and DESI has confirmed that cosmic star formation has collapsed by 60% over the last 4.5 billion years — yet the universe's supply of neutral hydrogen has b
