Gaia telescope uncovers giant wave rippling through Milky Way
Rapportert av AI
Astronomers using the European Space Agency's Gaia telescope have discovered a colossal wave propagating through the Milky Way galaxy, affecting stars tens of thousands of light-years away. This undulating motion, visible in the galaxy's disc, resembles ripples in a pond and involves both stellar positions and movements. The origin of this phenomenon remains unknown, though it may stem from a past galactic collision.
