Mars’s longest morning cloud may form ice without dust
A new model suggests Mars’s Arsia Mons Elongated Cloud forms partly through ice nucleation without dust seeds.Rapid cooling…
Scientists calculate how much information exists in the observable universe
A theoretical calculation estimates roughly 6 × 10⁸⁰ bits of information in selected ordinary-matter particles across the observable…
NASA plans radar and seismic tests for a hidden lunar cave that could shelter future astronauts

Earth’s magnetic field took 70,000 years to complete an ancient reversal
North Atlantic sediments record two magnetic reversals lasting approximately 18,000 and 70,000 years, longer than commonly assumed.The findings…
Five-dimensional black holes offer a possible explanation for dark matter and neutrinos
A theoretical study predicts five-dimensional primordial black holes within a model containing a hidden extra spatial dimension.Some modeled…
Cosmic gamma rays test the limits of Einstein’s speed of light rule
A reanalysis of cosmic gamma-ray measurements found no evidence of the tested departures from Lorentz invariance.The researchers tightened…
Rainstorms billions of years ago may have created habitable hotspots on Mars
A new global model suggests ancient Mars did not receive prebiotic formaldehyde evenly. Rainfall and atmospheric water vapor…
Asteroid Bennu may have formed much closer to the Sun than scientists thought
Isotope measurements from asteroid Bennu closely match those of asteroid Ryugu and rare CI carbonaceous chondrites, suggesting all…
Scientists outline how spacecraft could reach a nearby black hole within a century
A speculative mission concept proposes sending laser-powered, gram-scale spacecraft to a black hole that could potentially exist within…
CERN recreates cosmic ray collisions to reveal what happens when space particles hit Earth
Physicists at CERN have directly measured proton-oxygen collisions at 9.62 TeV per nucleon pair, closely recreating an important…
A cosmic giant 5,000 times the Milky Way’s mass emerges from the early Universe
Astronomers have reconstructed detailed three-dimensional maps of two enormous protoclusters seen when the universe was only about 2.1…
The Moon may have formed almost intact within hours of Theia smashing into Earth
New simulations of the Moon-forming giant impact show that treating the early Earth and Theia as realistic geological…
