Jun 14, 2024 · The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...
3 days ago · The solar force, attenuating inversely with distance in the planes of the orbits, was the major physical principle that guided Kepler’s struggle to construct a better orbital theory for Mars.
Jul 1, 2024 · Solar energy is radiation from the Sun that is capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s energy requirements and could satisfy all future energy needs if suitably harnessed.
Jun 13, 2024 · The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields. The Sun’s gases are constantly moving, which tangles, stretches and twists the magnetic fields.
Jun 26, 2024 · Approximately 330,000 times that of Earth, the Sun’s mass dominates the gravitational dynamics of our solar system. This staggering figure, detailed in a study by the National Aeronautics and Space Administration (NASA), highlights the sun’s central role in the cosmic dance of planets and other celestial bodies.
Jun 13, 2024 · Our story starts about 4.6 billion years ago, with a wispy cloud of stellar dust. This cloud was part of a bigger cloud called a nebula. At some point, the cloud collapsed—possibly because the shockwave of a nearby exploding star caused it to compress.
