coma
gaseous envelope immediately surrounding the nucleus of a comet
An area of dust or gas surrounding the nucleus of a comet
A sleep-like state; not conscious May be due to a high or low level of glucose (sugar) in the blood See also: Diabetic coma
A lens aberration or defect that causes rays that pass obliquely through the lens to be focused at different points on the film plane
An off-axis aberration that results in blurry star images near the edge of the field of view It is most common in fast f-ratio reflecting telescopes Parabolic Mirror: A parabolic or more accurately a “paraboloidal” mirror, is ground to a shape which brings all incoming light rays to a perfect focus , on axis
A state of sleep from which one may not wake up, usually induced by some form of trauma
A state of profound insensibility from which it is difficult or impossible to rouse a person
a lens aberration occurring in that part of the image field that is some distance from the principal axis of the system It results from different magnification in the various lens zones Extra-axial object points appear as short comet-like images with the brighter small head toward the center of the field (positive coma) or away from the center (negative coma)
When referring to optics, Coma is a type of aberration (The word coma is also used to describe a part of a comet ) Coma is usually short for the more specific term Off-Axis Coma When coma is present in an optical system stars at the center of the field appear as nice little pinpoints (assuming no other aberrations are present) while the stars near the edge of the field are elongated radially away from the center of the field This effect is seen especially in Newtonian telescopes with fast focal ratios and is minimized by using a coma-corrector lens ahead of the eyepiece or by using special eyepieces that diminish coma
a state of deep and often prolonged unconsciousness; usually the result of disease or injury (astronomy) the luminous cloud of particles surrounding the frozen nucleus of a comet; forms as the comet approaches the sun and is warmed a usually terminal tuft of hairs especially on a seed
A state of profound unconsciousness from which the individual cannot be roused which may be due to the action of an ingested toxic substance or one formed in the body, to trauma or to disease
A lens aberration which occurs in that part of the image field which is slightly away from the principal axis of the system Coma is fundamentally due to the faulty position of the principal points of the lens
The diffuse gaseous component of the head of a comet; i e , the cloud of evaporated gas around a comet nucleus
(1) The dust and gas surrounding the nucleus of a comet
A state of unconsciousness from which the patient cannot be aroused, even by powerful stimulation Coma involves the loss of awareness of self and the surrounding environment
An effect occurring during the formation of an off-axis image in a telescope Stars whose light enters the telescope at a large angle acquire comet-like tails on their images The brightest part of a comet, often referred to as the "head "
{i} state of being unconscious for an extended period of time
The dust and gas that form around a comet's nucleus as the Sun heats it
The envelope of a comet; a nebulous covering, which surrounds the nucleus or body of a comet
