Sun
The Sun is the star located at the solar system’s center. Its gravity holds the solar system as a whole together. It accounts for about 99.86% of the total solar system’s mass.
Hydrogen is about 73% of the Sun’s total mass; the rest is mostly Helium (25%), with a small quantity of oxygen, carbon, neon, and iron. The hottest part of the Sun is its core, where temperatures top 27 million degrees Fahrenheit (15 million degrees Celsius).
The core is the place where it generates enormous amounts of energy through the nuclear fusion reaction. It mainly radiates energy through visible light, ultraviolet, and infrared radiation.
Swift tracks water loss from an interstellar comet 2I/Borisov
2I/Borisov is the first observed interstellar comet, and the second observed interstellar interloper after ʻOumuamua'. It has 14 times the size of Earth with...
Magnetic threads around 500km in width found on the Sun

ESA’s Solar Orbiter launched successfully
Solar Orbiter will address big questions in Solar System science to help us understand how our star creates and controls the giant bubble of plasma that surrounds the whole Solar System and influences the planets within it. It is an ESA mission with strong NASA participation.
Mystery solved: How hazardous space radiation begins?
The study highlights a new phase of the energization process that is critical for the formation of radiation hazards.
