Nuclear Deflection Could Work on Metal-Rich Asteroids, Study Finds

New research shows metal-rich asteroid material can harden and self-damp under intense stress from a nuclear deflection, suggesting larger devices could be used without catastrophic fragmentation and preserving a last-resort option for very large or short-warning threats; NASA/ESA plan to study Apophis in 2029 and researchers will test more asteroid types (e.g., pallasites) to better inform planetary defense and hint at planetary formation insights.

Private donors back CERN's multi-decade Future Circular Collider plan

CERN has secured $1 billion in private donations from the Breakthrough Prize Foundation, the Eric and Wendy Schmidt Fund, John Elkann, and Xavier Niel to kick off the Future Circular Collider (FCC), a 90.7-km tunnel intended as the Large Hadron Collider’s successor. The plan features a two-phase roadmap: FCC-ee as a Higgs factory starting around 2030 with operations by 2047, followed by FCC-hh protons at 85 TeV in the 2070s to probe new physics. A CERN Council decision is expected in 2028, with construction potentially starting in 2030. China’s CEPC stall may open collaboration opportunities modeled after ITER, while the HL-LHC upgrade remains a priority in the near term.

CERN chills the LHC to chase new physics

The Large Hadron Collider is being upgraded to reach extreme cryogenic temperatures to improve measurements and reduce electronic noise. A new CO2-based heat exchanger, developed with Swep, cools Atlas components to -45C, while other accelerator sections reach 1.9 Kelvin for superconducting magnets. This relies on dilution refrigeration using helium-4 and helium-3, a key tech for quantum computing, with broader applications in cryogenic cooling for semiconductors and even supermarket refrigeration. By achieving colder conditions, scientists aim to probe physics beyond the Standard Model.

Large Hadron Collider Temporarily Ceases Operations

The Large Hadron Collider (LHC) in Switzerland will be shut down starting June for about five years to undergo major upgrades to increase its collision capacity, with the goal of enabling more advanced experiments. During this period, CERN is also planning the development of the Future Circular Collider, a much larger and more powerful accelerator, although its future is uncertain due to high costs and scientific debates. The LHC's shutdown is part of ongoing efforts to deepen our understanding of fundamental physics, including the universe's origins.

Scientists Recreate Cosmic Fireballs at CERN to Uncover Gamma-Ray Mysteries

Scientists at CERN recreated cosmic jet conditions using particle accelerators to investigate missing gamma-rays from blazars, finding that plasma beam instabilities are too weak to explain the phenomenon, which supports the idea of relic magnetic fields in intergalactic space. This experiment provides new insights into cosmic jet physics and the universe's magnetic history.

Plasma Fireballs Unveil Secrets of Supermassive Black Holes

Scientists at CERN created plasma fireballs to test hypotheses about the behavior of jets from supermassive black holes called blazars, finding evidence that weak intergalactic magnetic fields may disrupt particle cascades, helping to explain their mysterious jets.

Hidden Layers of Reality Beneath the Standard Model

Scientists are exploring the possibility of a hidden layer of reality called the 'zeptouniverse' at scales smaller than those currently accessible by the Large Hadron Collider, using indirect methods like studying rare particle decays, which could reveal new physics beyond the Standard Model within the next decade.

CERN's Latest Findings Shed Light on Matter-Antimatter Asymmetry

A new discovery at Cern's LHCb experiment reveals differences in the decay rates of matter baryons and their antimatter counterparts, providing insights into why the universe is dominated by matter and not antimatter, and hinting at potential new physics beyond the standard model.

Humans Create Object Over 300,000 Times Hotter Than the Sun

In 2012, CERN's Large Hadron Collider achieved the creation of the hottest artificially produced temperature ever, reaching 5 trillion Kelvin, which is about 100,000 times hotter than the Sun's core and similar to conditions microseconds after the Big Bang, by colliding lead ions at near-light speeds to study primordial matter.
