The Astronomy Picture of the Day (APOD) for July 30, 2025, features an awe-inspiring image of coronal loops on the Sun, offering a rare glimpse into the dynamic behavior of our star. Captured by ...

A new model that posits the same physical process is responsible for magnetic field and the rotation patterns, contradicting previous theories that the sun’s magnetic field originates deep inside its ...

Lunar rocks collected by Apollo astronauts more than half a century ago are providing a fresh take on the moon's mysterious magnetic field, scientists reported Wednesday.Samples to be retrieved by ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...
