Gaia telescope uncovers giant wave rippling through Milky Way
Riportato dall'IA
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.
Nearest alien civilization may be 33,000 light years away

New research suggests the closest technological civilization in the Milky Way could be about 33,000 light years from Earth. For such a society to coexist with humanity, it would need to have endured for at least 280,000 years. The findings, presented at a joint meeting in Helsinki, underscore the rarity of extraterrestrial intelligence.
