The analysis of spectra, especially light or mass spectra, to determine properties of their source. &diamf3; In light or optical spectroscopy , the spectrum of a light source is analyzed through a spectroscope to determine atomic composition of a substance. In astronomy, phenomena such as red shift can also be analyzed. &diamf3; In mass spectroscopy , a spectroscope is used to determine the composition of ions or charged molecules in a sample. Spectroscopy is also called spectrography.
(Astronomy) Either of two points in the orbit of a solar system body where the body is in opposition to or in conjunction with the sun.
A point of infinite density and infinitesimal volume, at which space and time become infinitely distorted according to the theory of General Relativity. According to the big bang theory, a gravitational singularity existed at the beginning of the universe. Singularities are also believed to exist at the center of black holes.
The point at which an orbiting object, such as a planet or a comet, is closest to the Sun.
(Uncountable) Smoked Nova Scotia salmon.
The definition of a nebula is a cloud of gas and dust in outer space.
A specific theory or model of this structure and these dynamics.
(Electricity) A faint glow enveloping the high-field electrode in a corona discharge, often accompanied by streamers directed toward the low-field electrode.
A file that contains the executable version of a computer program.
The relationship between the components of a conjunction.
A defect in a lens or mirror that prevents light rays from being focused at a single point and results in a distorted or blurred image. &diamf3; Aberration that results in distortion of color is called chromatic aberration. &diamf3; Aberration that is caused by imperfections in the surface or shape of a spherical mirror or lens is called spherical aberration.
