New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

Although no aliens were found, the results have helped constrain expectations of possible alien transmitter power. When you purchase through links on our site, we may earn an affiliate commission.
