martinezlaura+FollowUniverse’s First Light Decoded?Scientists just picked up a radio signal from over 13 billion years ago—basically the universe’s baby monitor! This 21-centimetre signal could finally spill the tea on how the first stars and galaxies lit up the cosmos. With new radio telescopes like REACH, we might soon know what those OG stars were really like (spoiler: they’re nothing like the ones we see today). Space nerds, this could change everything we know about our cosmic origins! #SpaceDiscovery #CosmicOrigins #Astrophysics #Science50Share
