Scientists Discover Cosmic Clock in Zircon Crystals That Tracks Earth’s Landscape History
Scientists have identified a natural “cosmic clock” inside zircon crystals that can date Earth’s surface processes over millions of years. By measuring cosmogenic krypton created by cosmic rays, researchers reconstructed erosion rates in southern Australia, revealing an exceptionally stable landscape shaped slowly over 40 million years and ex...

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

Scientists Recreate Cosmic Ray Physics Using Cold Atom in New Laboratory Study
Scientists have successfully recreated Fermi acceleration in a lab using ultracold atoms and movable optical barriers, simulating how cosmic rays gain energy in space. Developed by teams from Birmingham and Chicago, the mini Fermi accelerator marks a major advance in particle physics, opening doors to high-energy astrophysics studies and innovation...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

Scientists Detects Most Energetic Neutrino Ever in the Mediterranean Sea
A record-breaking neutrino with 220 quadrillion electron volts has been detected in the Mediterranean Sea. Captured by the KM3NeT deep-sea telescope, this rare cosmic event could be linked to powerful astrophysical phenomena such as black holes or supernovae. Neutrinos, nearly massless particles that rarely interact with matter, provide crucial ins...

AMS Data Reveals Charged Particle Variations in Heliosphere Over Solar Cycle
Researchers analysing AMS data aboard the ISS have identified variations in charged particles within the heliosphere over an 11-year solar cycle. Shifts in the heliospheric magnetic field impact antiproton behaviour and cosmic nuclei fluxes, revealing correlations between solar modulation and cosmic ray movement. AMS measurements provide insights i...

Cosmic Rays Could Help Scientists Study Tornado Formation Through Muon Detection
Cosmic rays and their byproduct, muons, may help scientists study tornado formation by detecting pressure changes remotely. This technique would avoid the need for direct measurements within dangerous storms. Researchers plan to use muon detectors over large areas or portable versions to track severe weather patterns. The findings could enhance und...

Astronomers Uncover New Details of CIZA0107 Galaxy Cluster Merger with VLA
A team of astronomers, led by Emma Schwartzmann from the U.S. Naval Research Laboratory, used the Very Large Array (VLA) to study the nearby galaxy cluster merger CIZA J0107.7+5408 (CIZA0107). The observations provided new insights into the dynamics of galaxy mergers, revealing a disturbed system with two subclusters and diffuse radio emission span...

Cosmic Rays Could Erase Signs of Life on Mars, Study Reveals
A new study highlights how cosmic radiation is destroying signs of ancient life on Mars. Organic materials like lipids degrade quickly under radiation, especially in salt-rich environments. Scientists suggest future Mars exploration should focus on deeper drilling, such as ESA's upcoming Rosalind Franklin Rover mission, to avoid surface radiation e...
