Ion Tail

ion tail - up to 100 million km long, it is composed of ions that interact with the solar wind.
A planet with a tail like a comet is slowly evaporating in the face of a wind of radiation from its parent star, according to brand new observations from the Hubble Space Telescope that are published in the latest issue of The Astrophysical Journal.
tail Component of a comet that consists of material streaming away from the main body, sometimes spanning hundreds of millions of kilometers. May be composed of dust or ionized gases.
Tail lobes--the two bundles of nearly-parallel magnetic field lines which stretch into the magnetotail, on opposite sides of the plasma sheet.
The Tail
When you have a large comet that moves well inside the orbit of Earth, you have the potential for a long tail. The current record holder for longest tail length is the Great Comet of 1843.
Ion tail--Even longer than the dust tail, consists of plasma. This is the part of the tail that interacts with the solar wind.
Where do they come from?
The Tail
The tails of bright comets can be 150 million kilometers (1 A.U.) in length, making them the "largest" objects in the Solar System. However, the tail is composed of gas and dust emitted from the nucleus and is very diffuse.
The tail of a comet
The gas which is blown away from the coma is ionised by solar radiation and becomes electrically charged.
The Tail
Three jets that spew molecules from the comet's surface when it becomes heated up by the sun form the most visible part of the tail.
ion tail
The straight tail of a comet which is generated by particles from the solar wind.
gas tail (type I): The tail of a comet produced by gas blown outward by the solar wind. (See dust tail.)
gene: A unit of DNA containing genetic information that influences a particular inherited trait.
Head-tail radio galaxies are often found in clusters. These are heavily distorted double sources that exhibit a swept-back appearance.
anti-tail
The name given to a comet's tail when it points toward the sun. This rare event typically occurs when Earth crosses the plane of the comet's orbit and the comet is relatively close to the sun.

Tail
A tail is made up of dust and gas from a comet's coma. A tail forms when the solar wind separates dust and gas from the coma, pushing it outward and away from the Sun in either a slightly curved path (for dust) or a straight path (for gas).

Ion Tail: A tail of charged gases (ions) always faces away from the sun because the solar wind (ions streaming from the sun at high velocities) pushes it away (it is also called the plasma tail).

Islands or high land, elevated above the surroundings and interrupting the air stream, can produce "tails" as well as "wakes.
The gas tail is much more highly charged, made of CO+, N2+, and CO2+ ions. The ions - electrically charged particles - interact with the sun's solar wind, causing a comet magnetotail that points away from the sun.
The ion tail is formed as a result of the photoelectric effect of solar ultra-violet radiation acting on particles in the coma.

Does the tail always follow behind a comet ?
Another misconception about comets is that as they hurtle through space the tail follows behind. In fact the tail is caused by the solar winds so it always points away from the sun.
