New Galaxy Map Reveals Dark Matter Secrets, Unraveling Universe's Enigma

• Scientists hope a new high-resolution map of distant galaxies, created with the James Webb Space Telescope, will lead to a major breakthrough in understanding dark matter.
• Dark matter constitutes over 25% of the universe, while ordinary matter (stars, planets, humans) makes up only 5%, and the rest is dark energy.
• Dark matter is mysterious because it neither absorbs nor emits light, making it invisible, but its gravitational effects on light from distant galaxies are observable.
• The new map, published in Nature Astronomy, is the most detailed to date, showing galaxy clusters and invisible dark matter structures, referred to as the 'cosmic skeleton'.
• Understanding dark matter is crucial for comprehending the universe's formation and expansion, as it plays a decisive role in shaping cosmic structures.

Why It Matters: A new James Webb Telescope galaxy map offers unprecedented detail, promising to unlock dark matter's secrets and universe's structure.
