The Double Helix Nebula is a gaseous nebula near the center of our galaxy. In Astronomy, an epoch is a moment in time used as a reference for the Orbital elements of a Celestial body. An emission nebula is a Cloud of Ionized Gas ( ie a plasma) emitting light of various colors In Astronomy, diffuse nebulae is the general term for illuminated Nebulae The three types of diffuse nebulae are Reflection nebulae Emission A nebula (from Latin: "mist" pl nebulae or nebulæ, with ligature or nebulas) is an Interstellar cloud of The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Γαλαξίας (Galaxias sometimes referred to simply It is thought to have been distorted by magnetic torsion into the shape of two connected spirals, known popularly as a double helix, akin to the shape of DNA. In Solid mechanics, torsion is the twisting of an object due to an applied Torque. In Geometry a double helix (plural helices) typically consists of two congruent helices with the same axis differing by a translation Deoxyribonucleic acid ( DNA) is a Nucleic acid that contains the genetic instructions used in the development and functioning of all known
The nebula was discovered by the Spitzer Space Telescope. The Spitzer Space Telescope (formerly the Space Infrared Telescope Facility, SIRTF) is an Infrared Space observatory. The segment seen so far is thought to be 80 light years long, 300 light years from the supermassive black hole thought to be at the galaxy's center, and 25,000 light years from Earth[1]. A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by A supermassive black hole is a Black hole with a Mass of an order of magnitude between 105 and 1 EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001
This nebula is seen as circumstantial evidence that the magnetic fields at the center of the galaxy are extremely strong, more than 1,000 times stronger than those of the Sun. The Sun (Sol is the Star at the center of the Solar System. If so, they may be driven by the massive disc of gas orbiting the central supermassive black hole. A supermassive black hole is a Black hole with a Mass of an order of magnitude between 105 and 1 These magnetic fields have been interpreted as possible evidence supporting an alternative theory of black hole structure called the magnetospheric eternally collapsing object. A Magnetospheric Eternally Collapsing Object or MECO is a proposed alternative to a Black hole.
The Double Helix Nebula should not be confused with the Helix Nebula, a planetary nebula only 650 light years from Earth. The Helix Nebula, also known as The helix or NGC 7293, is a large Planetary nebula (PN in the sky and is placed the zodiac Constellation
