Cosmology
Astronomers using NASA’s James Webb Space Telescope have produced the most detailed map yet of the universe’s cosmic web, the vast network of dark matter and gas that links galaxies. The map traces structures back to when the universe was roughly one billion years old.

A new analysis from Queen Mary University of London proposes that the universe's physical constants occupy a narrow range allowing liquids to flow properly inside living cells.
Astronomers have identified a bright supernova from over 10 billion years ago, its light gravitationally lensed into multiple images by a foreground galaxy. This unique observation allows simultaneous views of different stages of the explosion. The time delays between images could reveal details about the universe's expansion rate and dark energy.

Astronomers have discovered that the Milky Way resides within a vast, flat sheet of matter dominated by dark matter, surrounded by enormous empty voids. This structure explains why most nearby galaxies are moving away from our Local Group rather than being drawn in by gravity. The finding, based on advanced simulations, resolves a longstanding puzzle in cosmology.
