Gaia telescope data from the European Space Agency reveal a wave rippling through the Milky Way, affecting stars up to 65,000 light-years from the galactic center.
The wave resembles a stadium wave, and Eloisa Poggio's team is investigating its origins and link to the Radcliffe Wave.
Separately, pulsars are monitored for gravitational waves, with studies indicating a gravitational-wave background from supermassive black hole mergers and primordial waves from Big Bang.
