Primordial magnetism offers fresh angle on the Hubble constant puzzle
Wednesday, 21 January 2026 12:11
A Simon Fraser University cosmologist reports that new theoretical work on primordial magnetic fields could move researchers closer to resolving the longstanding Hubble tension, the mismatch in measurements of how fast the universe is expanding today.
The Hubble tension arises because two precise approaches to determining the Hubble constant give significantly different results, despite dr ALMA survey maps turbulent youth of distant planetary systems

Astronomers have assembled the most detailed view so far of planetary systems in a long elusive stage between their birth and maturity, using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) has produced the sharpest images yet of 24 debris discs, the dusty belts that remain once the main phase of planet formation is Century-old solar records refine future cycle forecasts

An international team of astronomers has developed a new way to extract solar polar magnetic information from more than a century of historical observations, improving prospects for predicting future solar cycle activity. The work combines data from the Kodaikanal Solar Observatory in India with modern measurements to reconstruct the behavior of the Sun's polar magnetic field over more than 100 U.S. vulnerable to Russian escalation in space, new report warns

Hubble uncovers the secret of stars that defy ageing
Wednesday, 21 January 2026 09:00
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbours, looking far younger than their true age. Known as blue straggler stars, these stellar oddities have puzzled astronomers for more than 70 years. Now, new results using the NASA/ESA Hubble Space Telescope are finally revealing how these 'forever young' stars come to be and why they thrive in quieter cosmic neighbourhoods.

Magnetic avalanches power solar flares, finds Solar Orbiter
Wednesday, 21 January 2026 07:00
Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.
