McGill University researchers have revealed that changes in cloud cover are helping to slightly counteract global warming. While greenhouse gases continue to drive temperatures upward, a reduction in low-cloud cover over land has contributed to a small decrease in the amount of heat retained near the Earth's surface. "We started this research to observationally verify the increase of green

For decades, scientists have tried in vain to accurately predict solar flares - intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA's Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when the Sun is about to unleash a large flare. These warning signs

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it - the flickering star is 2.2 million light-years away, and is 1/100,000th the brightness of the faintest star visible to the human eye. Yet, a century ago, its discovery by Edwin Hubble, then an astronomer at Carnegie Observatories,

A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny specks of a quark-gluon plasma (QGP). Scientists believe such a substance of free quarks and gluons, the building blocks of protons and neutrons, permeated the universe a fraction of a second after the B

New research from NASA's Chandra X-ray Observatory and ESA's XMM-Newton highlights the harsh space weather that planets around other stars may face. The study focused on the impact of X-rays on potential planets orbiting red dwarf stars, which are the most common type of star in the universe. The findings suggest that only planets with atmospheres rich in greenhouse gases, such as carbon d

A collaborative study by researchers from the University of Gottingen and the Max Planck Institute for Solar System Research (MPS) has offered new insights into the formation of the Moon and the origins of Earth's water. The findings challenge long-standing assumptions about the Moon's origin and propose that it may have formed primarily from material ejected from Earth's mantle, with minimal co
