Scintillation (astronomy)
Scintillation or twinkling are generic terms for rapid variations in apparent brightness or color of a distant luminous object viewed through the atmosphere.
Interplanetary Scintillation
The emits "blobs" of plasma (known as the ). Depending on the geometry, rays through different blobs can be focused to a single point.
SCINTILLATION
Scintillation is the twinkling of stars (fluctuation of intensity) seen through a planet's atmosphere. Scintillation in caused when the star's light is distorted by the Earth's atmosphere.
Scintillation
(a) In radio astronomy, a rapid oscillation in the detected intensity of radiation emitted by stellar radio sources, ...
Scintillation The twinkling of stars, resulting from atmospheric disturbance.
Secondary Abbreviation for secondary mirror. Small mirror that directs the light from the primary mirror to the eyepiece.
Scintillation. Another term used to describe the twinkling of a star. It is caused by the Earth's atmosphere distorting the light from a star, mainly when the star is at a low altitude.

Scintillation
A flash of light produced when gamma rays strike a certain material. The high energy of gamma rays makes them hard to capture but they can be detected using scintillation.

Interstellar Scintillation
Electromagnetic waves as they propagate though the interstellar media suffer frequency-selective fading. The resulting corrupted signal is said to undergo scintillation effects.

astronomical scintillation (NASA SP-7, 1965) Any scintillation phenomena, such as irregular oscillatory motion, variation of intensity, and color fluctuation observed in the light emanating from am extraterrestrial source; ...
Known to astronomers as scintillation, twinkling is caused by thermal motion of the air, which swirls air layers of different temperature and density.
Oriented Scintillation Spectrometer Experiment (OSSE) by the Naval Research Laboratory detected gamma rays entering the field of view of any of four detectors, which could be pointed individually, in the 0.05 to 10 MeV range.
Two scintillation detectors were placed next to the cadmium targets. Antineutrino charged current interactions with the protons in the water produced positrons and neutrons.
Two scintillation detectors were placed next to the cadmium targets. Antineutrinos with an energy above the threshold of 1.8 MeV caused charged current interactions with the protons in the water, producing positrons and neutrons.
In contrast with the isotropically emitted scintillation light, Cerenkov light is emitted along the surface of a forward-directed cone centered on the particle velocity vector.
This rapid change in brightness and position is termed scintillation. You may have used this to distinguish between a star and a planet merely by observing the night sky.
Earth-based telescopes, including our naked eyes, must contend with image distortion and scintillation caused by atmospheric disturbances as light reaches us from outer space.
" Random intensity fluctuations of starlight passing through the atmosphere are called "scintillation." You can easily see the effects of scintillation by looking up at night right after a cold front and see the star twinkle and change colors.
There is an internal scintillation sensor which uses a Stilben crystal and photomultiplier tube (PMT) to detect high energy (300 keV to 10 MeV) neutrons and gamma ray photons from 60 keV to 1 MeV, ...
If the seeing is good, detail is not blurred as much by atmospheric scintillation. Scintillation is what causes the stars to twinkle, which may be appreciated poetically, but usually means the seeing is not that good.
They record the attenuation, scintillation, refraction, rotation, Doppler shifts, and other direct modifications of the radio signal as it is affected by the atmosphere of a planet, moons, ...

Hewish and Bell were not looking for pulsars but were interested in scintillation of radio signals of quasars. During their survey they found an anomaly which finally turned out to be the signals of an fast rotating neutron star.
