Star Formation

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

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.

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."

Planetary Genesis: How Planets Are Born

How do stars and planets form? Scientists are now one step closer to pinning down the conditions for the formation of proto-stellar disks. Observations of three systems in the early stages of star formation in the Perseus cloud revealed that the profile of the angular momentum in these systems is between that expected for a solid body and pure turbulence, indicating that the influence of the core extends further out than previously thought. These findings could lead to more realistic initial…

Understanding the formation of stars and galaxies early in the Universe’s history continues to be somewhat of an enigma, and a new study may have turned our current understanding on its head. A recent survey used archival data from four different telescopes to analyze hundreds of galaxies. The results provided overwhelming evidence that radio jets … Continue reading "Jets Boost — Not Hinder — Star Formation in Early Galaxies, New Study Suggests"
