James Webb telescope discovers earliest galaxy in the known universe — and its shockingly bigThe James Webb Space Telescope has detected the two earliest, most distant galaxies in the known universe, dating to just 300 million years after the Big Bang. The detection of even earlier galaxies is likely to follow.

Scientists may have finally solved the problem of the universe’s 'missing' black holesPrimordial black holes are one of the strongest candidates for the universe's missing dark matter. But a new theory suggests that not enough of the miniature black holes formed for this to be the case.

James Webb telescope sees 'birth' of 3 of the universe's earliest galaxies in world-1st observationsThe James Webb Space Telescope may have spotted the birth of some of the earliest galaxies in the universe for the first time ever, new research hints.

Newfound 'glitch' in Einstein's relativity could rewrite the rules of the universe, study suggestsEinstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be modified.

The James Webb telescope may have found some of the very 1st stars in the universeThe James Webb Space Telescope zoomed in on galaxy GN-z11, which existed just 430 million years after the Big Bang, to reveal what may be some of the oldest stars in the universe.

James Webb telescope detects oldest 'dead' galaxy in the known universe — and its death could challenge cosmologyAstronomers using the James Webb Space Telescope have detected the oldest "dead" galaxy ever observed, at just 700 million years after the Big Bang. The stalled-out relic defies explanation by our current knowledge of the early cosmos.

James Webb telescope finds ancient galaxy larger than our Milky Way, and it's threatening to upend cosmologyAstronomers believe the first galaxies formed around giant halos of dark matter. But a newly discovered galaxy dating to roughly 13 billion years ago mysteriously appeared long before that process should have occurred.

Astronomers spot gigantic black hole killing a galaxy's star formation at the dawn of timeObservations made by Chile's ALMA telescope have revealed a gigantic quasar quenching a galaxy's star formation — a first-of-its-kind observation in the early universe.

Europe approves LISA, a next-generation space mission that will discover the faintest ripples in space-timeThe new LISA gravitational wave detector, which will be launched into orbit in 2035, promises to detect cosmic collisions from the earliest moments after the Big Bang.
