Cold interstellar gas does not emit radiation at visible wavelengths.
Transition states
For reactions activation energy roughly corresponds to the height of the barrier. The transition state along a reaction coordinate is the point of maximum free energy, where bond-making and bond-breaking are balanced.

Phase Transition
(a) An abrupt change in the equilibrium state of a system.
(b) A sudden transition between one state of matter or energy and another state.
Transitions among the various orbitals are unique for each element because the energy levels are uniquely determined by the protons and neutrons in the nucleus.

transition flow (NASA SP-7, 1965) = Knudsen flow. transition maneuver (NASA SP-7, 1965) In lifting flight, a maneuver required to fly smoothly from one equilibrium glidepath to another, performed by changing attitude in some manner.

Shock--A sudden transition at the front of fast flow of plasma or gas, when that flow moves too fast for the undisturbed gas to move out of its way. Also occurs when a steady fast flow hits an obstacle.
The principal types of radioactivity are alpha decay, beta decay, and isomeric transition. To be considered as radioactive a process must have a measurable lifetime between approximately 10E-10 second and approximately 10E17 years.
The layer of the solar atmosphere above the PHOTOSPHERE and beneath the transition region and the CORONA. CHROMOSPHERIC EVENTS. Some flares are just Chromospheric Events without Centimetric Bursts or Ionospheric Effects.
Chromosphere The layer of the solar atmosphere that is located above the photosphere and beneath the transition region and the corona. The chromosphere is hotter than the photosphere but not as hot as the corona.
The " Procyon " or calcium stars form a transition between Type I. and Type II. proper, and show the lines of calcium besides those of hydrogen. An important variety of Type III.
With an age of 26 million years following its class B2 beginning, 67 Oph is now in a transition state in which, with a dead helium core, it is expanding to become a much larger red supergiant, ...
One theory pictures a gradual transition from the outer ammonia clouds to a thick layer of frozen gases and finally to a liquid or solid hydrogen mantle.
This transition area, called the Mohorovicic discontinuity, is prominently revealed by seismic wave analysis. It is believed that most basaltic magmas are generated near the base of the upper mantle at a depth of about 400 kilometres.
At great depths within the cloud other molecules can be seen from their microwave transitions, and more than 70 chemical species have been identified within the constituent gas.
This is possible because "gamma-ray" is the name given to the photons generated from nuclear decay or other nuclear and subnuclear processes, whereas X-rays on the other hand are generated by electronic transitions involving highly energetic inner ...

An intermediate stage in the transition from classical to scientific mapping was the Uranometria Nova of the German astronomer F. W. A. Argelander published in 1843.
Sedna appears to lie in a transition region between the Edgeworth-Kuiper Belt and the Oort Cloud. As of late 2005, only a few Edgeworth-Kuiper objects (EKOs) such as 2004 XR190 were known to have orbits that stay mostly beyond 50 AUs.
In the build-up to the episode the "NCC-7100" desktop model in Picard's office was replaced with the AMT model kit to accommodate the transition.

Turbulence can therefore be empirically described as the telescope aperture at which the transition from image oscillation to image speckling occurs, and this is defined for a specific wavelength as Fried's seeing parameter, r0.
Colorado team lead Kristian Hahn said the team expected to see both spring/mass systems exhibit the coupled mode and to observe the transition of momentum from linear to rotational.
