The sun loses mass due to the solar wind at a very small rate, (2–3) × 10 −14 solar masses per year. [2] The solar wind carries trace amounts of the nuclei of heavy elements fused in the core of the sun, revealing the inner workings of the sun while also carrying information about the solar magnetic field.

Hundred Million Stars from the Sky [1] (空から降る一億の星, Sora Kara Furu Ichioku no Hoshi) is a drama that aired on Fuji TV.It first aired in Japan from April 15, 2002 to June 24, 2002 every Wednesday.
Neutron stars are formed by the gravitational collapse of the cores of larger stars. They are the remnant of supernova types Ib , Ic , and II . Neutron stars are expected to have a skin or "atmosphere" of normal matter on the order of a millimeter thick, underneath which they are composed almost entirely of closely packed neutrons called ...
The free-fall time is the characteristic time that would take a body to collapse under its own gravitational attraction, if no other forces existed to oppose the collapse.. As such, it plays a fundamental role in setting the timescale for a wide variety of astrophysical processes—from star formation to helioseismology to supernovae—in which gravity plays a dominant ro
Astronomers have discovered a phenomenon that causes the sun to form enormous objects similar to meteors or "shooting stars" in its corona, the outer layer of its atmosphere, that then fall back ...
The angular momentum of a stellar black hole is due to the conservation of angular momentum of the star or objects that produced it. The gravitational collapse of a star is a natural process that can produce a black hole. It is inevitable at the end of the life of a massive star when all stellar energy sources are exhausted.
The main sequence is sometimes divided into upper and lower parts, based on the dominant process that a star uses to generate energy. The Sun, along with main sequence stars below about 1.5 times the mass of the Sun (1.5 M ☉), primarily fuse hydrogen atoms together in a series of stages to form helium, a sequence called the proton–proton chain.
An alignment of six planets will dazzle in January 2025. Venus, Mars, Jupiter, Saturn, Uranus and Neptune will align in the night sky. "The whole month of January is a great time to see the ...
