James Webb telescope detects oldest 'dead' galaxy in the known universe — and its death could challenge cosmology
Astronomers 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 cosmology
Astronomers 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 time
Observations 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-time
The 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.
Cosmic strings can break — and when they do, they shake the universe
Many models of the universe predict the existence of countless invisible strings stretching across space. New research finds a way these strings might snap — and how we could feel the fallout.
James Webb telescope discovers the oldest, most distant black hole in the universe
The James Webb Space Telescope's discovery of the universe's oldest black holes is giving astronomers some vital clues for how they came to be.
Tiny black holes from the dawn of time may be altering our planet's orbit, new study suggests
A study suggests primordial black holes may make planets and moons near us wobble. If measured experimentally, this will provide the first concrete proof such objects exist.
Unexpected cosmic clumping could disprove our best understanding of the universe
The tension, centered around a value for cosmic lumpiness known as S8, could join the Hubble tension in dethroning our best picture of how the universe evolved.
