A new study suggests Jupiter's strong magnetic field protected its large moons during formation, while Saturn's weaker field led to only one dominant moon, Titan.
The universe's expansion can cause distant galaxies to recede faster than light, a phenomenon that does not violate Einstein's theory of relativity because it involves the stretching of space itself, not the movement of objects through space.
A new study suggests stellar activity can distort extraterrestrial radio signals, making them harder to detect and potentially explaining the lack of observed alien communications.
A theoretical study suggests that dying stars might create new universes powered by dark energy, forming gravastars instead of black holes.
New research indicates that supermassive black holes can render exoplanets uninhabitable by stripping away atmospheres and depleting ozone, even at vast distances.
Astronomers have captured the clearest direct image of a cosmic web filament, revealing a three-million-light-year strand connecting two ancient galaxies.
A new study explores electron-nuclei interactions, providing fresh constraints on dark matter candidates and hypothetical particles beyond the Standard Model.
Solar radio bursts observed by the Parker Solar Probe reveal hidden magnetic switchbacks near the Sun, providing new insights into the Sun's magnetic field structures.
New research suggests gravitational waves in the early universe may have transformed into particles that eventually became dark matter, addressing a major mystery in physics.
