The universe is still accelerating: New study rejects claim that cosmic expansion has begun to slow down

An international team, including Nobel laureates Adam Ries and Brian Schmidt, found that the claim that dark energy is weakening was based on an incorrect age estimate of supernovae and the omission of a common correction in the mass
A planet and moons without a sun. New research suggests a previously overlooked setting for life: moons drifting through interstellar space with no sunlight at all. Under the right conditions, they could sustain lasting living environments. (Artist's rendering). . Illustration: depositphotos.com

Study: Moons of free planets may support life even without a sun

New model suggests hydrogen-rich atmospheres and tidal heating could keep liquid water on moons orbiting free-floating planets for up to 4.3 billion years, even in dark interstellar space

Right: An ancient globular cluster as it appears today: the remaining light stars retain traces of the winds of those extremely massive stars, which have already collapsed into intermediate-mass black holes.

Stars 10,000 times more massive than the Sun dominated the early universe

A new model suggests that extremely massive stars in ancient globular clusters shaped their chemical composition, contributing to the formation of the first galaxies and the emergence of intermediate-mass black holes.

New research investigates the effect of ozone on the climates of extrasolar planets

A team of researchers led by Dr. Assaf Hochman from the Hebrew University revealed the role of ozone in shaping the atmospheric dynamics of Proxima Centauri b. Their findings, derived from advanced models of climate chemistry and advanced theories of
