The James Webb Space Telescope may have broken another of its own records, finding potentially five of the earliest and most distant galaxies ever seen.
'Cosmic inflation:' did the early cosmos balloon in size? A mirror universe going backwards in time may be a simpler explanation
We live in a golden age for learning about the universe. Our most powerful telescopes have revealed that the cosmos is surprisingly simple on the largest visible scales.
Is the James Webb Space Telescope really 'breaking' cosmology?
While headlines around the world claimed that these galaxies were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.
Is the universe still making new galaxies?
It's a fun question to tackle because it lets us dig into the messy, complicated, beautiful process of galaxy formation.
Earth's upper atmosphere could hold a missing piece of the universe, new study hints
Mysterious dark matter could slosh over our planet like a wave. If it does, it may produce telltale radio waves in Earth's atmosphere, new theoretical research suggests.
Dark matter clue? Mysterious substance may be interacting with itself in nearby galaxy
A neighbor galaxy of the Milky Way could offer fresh clues in the 90-year-long quest to determine the nature of dark matter.
'Physics itself disappears': How theoretical physicist Thomas Hertog helped Stephen Hawking produce his final, most radical theory of everything

Where is the center of the universe?
Space mysteries Is there a center of the cosmos, and if so, where is it?
Massive 'El Gordo' galaxy cluster suggests dark matter smashes into itself
El Gordo is a massive collection of colliding galaxies 7 billion light-years away. Its odd behavior could suggest dark matter interacts with itself.
Euclid telescope: A scientist tells us of his quest to understand the nature of dark matter and dark energy
Clumps of dark matter reveal their presence by distorting the shapes of more distant galaxies, just like waves on the surface of a swimming pool distort the pattern of tiles on the bottom.
