Star Formation

Star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. This article describes the properties and evolution of individual stars. Included in the discussion are the sizes, energetics, temperatures, masses, and chemical compositions of stars.

How are stars formed? In this article we'll explain stars and learn how stars are formed.

Star Formation: Nebula, Red dwarf, Red giant, Planetary Nebula, White dwarf, Supernova, Black dwarf, Brown Dwarfs, Neutron stars, Black holes.

Astronomers are excited to get their first look at a clump of gas they think is about to start forming stars. Unlike others seen, this one is "pristine," unaffected by the violent stellar winds and supernova shocks from other nearby stars.

WASTED on Instagram: "The Antennae Galaxies (NGC 4038 and NGC 4039) collided gravitationally, forming a vast heart-like shape visible in space. Located 60 million light years away, they have been merging for a billion years, triggering star formation through colliding interstellar gases. Their iconic antennae structures and cosmic dance are expected to continue for another billion years."
