Enlarge / An artist’s composition of the Milky Way seen with a neutrino lens (blue). IceCube Collaboration/NSF/ESO reader comments 19 with Scientists with the IceCube Neutrino Observatory have unveiled a striking new image of our Milky Way galaxy as seen by ghost-like messenger particles called neutrinos. This new analysis—announced at a Drexel University event today, with a ..

Enlarge / Cosmic rays showering down on Earth’s atmosphere are the basis of a new wireless alternative system to GPS navigation. 2015 Hiroyuki K.M. Tanaka reader comments 54 with GPS is now a mainstay of daily life, helping us with determining locations, navigation, tracking, mapping, and timing across a broad spectrum of applications. But it ..
Enlarge / Archaeologists used cosmic rays to detect a secret underground burial chamber from the Hellenistic period in Naples, circa late fourth century/early third century BCE. This is a laser-scanned 3D view of the underground part of the site V. Tioukov et al., 2023 reader comments 11 with The ruins of the ancient necropolis of ..
Enlarge / The red arcs at the right of center are background galaxies distorted by gravitational lensing. The number, location, and degree of distortion of these images depends on the distribution of dark matter in the foreground. reader comments 50 with Share this story Decades after it became clear that the visible Universe is built ..
