Atmosphere survival model refines search for habitable planets
Atmosphere survival model refines search for habitable planets Gaby Clark Scientific Editor Robert Egan Associate Editor Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain life-supporting atmospheres, focusing on size and atmospheric dynamics. Since 1992, NASA has confirmed the existence of over 6,000 planets outside of our solar system, and over 7,000 suspected planets still await confirmation. These distant planets, dubbed...
Wildfires reverse decade of ozone cleanup in the United States, study reveals
Wildfires reverse decade of ozone cleanup in the United States, study reveals Sadie Harley Scientific Editor Robert Egan Associate Editor Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ozone air quality standards in the U.S.," led by University of Iowa researchers and published in the journal Science. Exposure to...
Stonehenge Altar Stone's epic transportation across ancient Britain detailed in new study
Stonehenge Altar Stone's epic transportation across ancient Britain detailed in new study Robert Egan Associate Editor New research by Curtin University has revealed how one of Stonehenge's most mysterious stones was likely transported hundreds of kilometers across Britain through challenging terrain, highlighting the remarkable capabilities of ancient communities. Stonehenge's central Altar Stone is a six-tonne sandstone megalith now believed to have originated in northeast Scotland, around...

Stonehenge's most mysterious stone traveled 700 kilometers across Britain - Date: - June 9, 2026 - Source: - Curtin University - Summary: - Scientists have uncovered new evidence that Stonehenge’s six-ton Altar Stone was deliberately transported hundreds of kilometers from Scotland by ancient people. The feat would have required extraordinary planning, teamwork, and determination, revealing a surprisingly sophisticated level of organization thousands of years ago. A new study led by...
Jupiter bow shock reveals electrons accelerating to relativistic speeds
Jupiter bow shock reveals electrons accelerating to relativistic speeds Sadie Harley Scientific Editor Robert Egan Associate Editor Electrons around Jupiter have been caught in the process of being accelerated, revealing a potentially unified mechanism for particle acceleration. The findings, published in Nature, may help constrain how energetic particles are produced throughout the universe. Shocks are disturbances created by a perturber/object/fluid moving through a fluid faster than the...
Hundreds of new moons are revealing our solar system's violent history
In the far reaches of the solar system, the planetary neighbourhood seems quiet. Beyond Jupiter, the sun is no longer a blazing disc, but a cold, white lamp. The planets are separated by gulfs of darkness.
Ceres' surface is much more complex than previously thought
Ceres' surface is much more complex than previously thought Lisa Lock Scientific Editor Andrew Zinin Lead Editor The long, puzzling dwarf planet Ceres, in reality the first named asteroid, has surface features that are much more complex than previously thought. Or at least that's the conclusion of a recent paper presented at the European Geosciences Union 2026 General Assembly in Vienna. New data analysis from NASA's Dawn mission points to a surface with steep slopes, fractures, and albedo...
