Dark Matter Mystery

Scientists at the Large Hadron Collider (LHC) are continuing their search for dark matter, the elusive substance that makes up about 85% of the universe's mass. While no direct detection of dark matter particles has been made yet, experiments at the LHC and other facilities are narrowing down the possibilities and exploring new theories about the nature of dark matter. Solving the mystery of dark matter is one of the biggest challenges in modern astrophysics.

Three iron rings in a planet-forming disk

Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the gaps between the rings. The detailed analysis is consistent with abundant solid iron grains complementing the dust composition. As a result, the disk likely harbors metals and minerals akin to those in the Solar System's terrestrial planets. It offers a glimpse into conditions resembling the early Solar System over four billion years ago during the formation of rocky planets such as Mercury, Venus, and Earth.
