Astrophysics From Wikipedia, the free encyclopedia Jump to: navigation search NGC 4414 , a typical spiral galaxy in the constellation Coma Berenices , is about 56,000 light-years in diameter and approximately 60 million light-years distant Astrophysics is the branch of astronomy that deals with the physics of the universe , including the physical properties ( luminosity density temperature , and chemical composition) of celestial objects such as stars galaxies , and the interstellar medium , as well as their interactions. The study of cosmology is theoretical astrophysics at the largest scales where Albert Einstein 's general theory of relativity plays a major role. Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics electromagnetism statistical mechanics thermodynamics ... nuclear and particle physics , and atomic and molecular physics . In practice, modern astronomical research involves a substantial amount of physics. The name of a university's department ("astrophysics" or "astronomy") often has to do more with the department's history than with the contents of the programs. Astrophysics can be studied at the bachelors masters , and Ph.D.

SAO star catalog Galaxy M31 in Andromeda Horsehead Nebula IC 434 Links Astrometry.org About Astrophysical.org Astrophysics on astrophysical.org Astrophysics is the branch of astronomy that deals with the physical properties of stars , galaxies, and other astronomical objects. Among such characteristics are: temperature, luminosity, color, density and chemical composition of stars. Cosmology is theoretical astrophysics at its largest scale, involving the structure of the whole universe. Astrophysical research is important for physics at atomic and subatomic scales. Most of modern astronomical research involves a substantial amount of physics and can be considered astrophysics. However, astronomy is considered to be separated into 3 traditional branches: astrometry and celestial mechanics are the classical fields of astronomy; astrophysics is the modern field. The current high status of astrophysics is reflected in the naming of institutions involved in astronomical research: the oldest ones are "astronomy" departments or institutes, the newest ones include "astrophysics" in their names, often excluding the word "astronomy". Astrometry and celestial mechanics are so related that they may be considered a single branch: for this reason, the Scientia websites are only two

In 2005, the Cassini spacecraft flew by Enceladus and saw plumes of material erupting from the south pole of Enceladus. Scientists were surprised to see this because eruptions are powered by heat from an object's interior. Enceladus is tiny compared to most moons, only about 500 kilometers (310 miles) in diameter, so it should have lost its interior heat to the cold of space long ago. May 9, 2007

Research in astrobiology and interstellar chemistry describes the evolution of interstellar clouds into new solar systems . Current interest focuses on spectroscopic detection of organic molecules in interstellar dust and gas, and their contribution to the organic inventory of protoplanetary disks. Theoretical projects include simulations of protostellar collapse, multifluid magnetohydrodynamic shock waves, and shock chemistry. Research in galactic and extragalactic astronomy includes the structure and formation of the galactic halo, metallicity gradients in the galactic thick disk, properties of stars with strong Balmer absorption, optical properties of quasars, and astronomical data mining. The astrophysics group makes use of ground-based telescopes located at world class observing sites in Hawaii, Australia, Chile, and South Africa. We also have access to data from major satellite facilities, including the Hubble Space Telescope, Chandra, and the Infrared Space Observatory; and large ground-based astronomy projects, including the
