Cosmic dust is the raw material of planets and our own bodies. In Sextans A, a primitive dwarf galaxy with just 3-7% of the Sun's heavy elements, JWST spotted stars making dust out of almost nothing but iron. SORABUMI unpacks the surprising answer to how the early universe managed to make dust at all.
JWST kept finding strange red dots in the early universe, dubbed 'Little Red Dots.' In June 2026, a spectrum of one such object, GLIMPSE-17775, revealed over 40 emission lines and 16 iron absorption lines — proof it isn't a galaxy at all, but a black hole wrapped in gas. From space media outlet SORABUMI.
A massive galaxy with barely any rotation has been discovered just 1.8 billion years after the Big Bang. JWST's observations are quietly dismantling the assumption that young galaxies always spin.
Just 300 million years after the Big Bang, a galaxy rivaling the Milky Way in 'maturity' already existed. JADES-GS-z14-0, discovered by JWST, is challenging the foundations of cosmology.
A spiral galaxy nearly identical to the Milky Way was found just 1.5 billion years after the Big Bang. Here's what JWST's stunning discovery means for galaxy formation — and why the old theories are struggling to keep up.
