2 days ago · The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
Sep 27, 2024 · The Short Answer: Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. It's all about Earth's tilt!
3 days ago · The Sun has a radiative core surrounded by a convective envelope, and at the boundary of these two is the tachocline. However, brown dwarfs lack radiative cores and tachoclines. Their structure consists of a solar-like convective envelope that exists from core to surface.

1 day ago · The magnetic field plays a dominant role in many physical processes that occur on the Sun, including transient solar eruptions, plasma heating, and the 11-year solar activity cycle. Understanding these phenomena requires measurements of the evolving magnetic field at all altitudes in the Sun’s atmosphere (1 – 3).
