James Webb telescope reveals clearest map of cosmic web

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.

Study links fundamental constants to life through liquid flow

Rare lensed supernova from 10 billion years ago may aid dark energy research

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 uncover giant cosmic sheet around the Milky Way

06 मार्च 2026 AI द्वारा रिपोर्ट किया गया

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.
