Transits occur when either Mercury or Venus move directly between the Earth and the Sun. Each planet is then seen in silhouette as a black disk in front of the Sun's surface in a phenomenon rather like an interplanetary solar eclipse.

Craters in Transition
Magellan's radar system detected few impact in the process of being resurfaced by volcanism. is the largest of these craters in transition, with a diameter of 63 km (39 mi).
Historically, transits of Venus were of paramount scientific interest, because it enabled astronomers to determine what's called the Astronomical Unit (AU) -- the mean distance between the Earth and the Sun.
Intriguingly, the transit timing variations may also enable Kepler to discover additional planets that cannot be seen transiting (because the angle of their orbit is too great to cross the face of their star's disc), ...
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.
Transits. In 1882, the transit of Venus and a Sun-grazing comet were recorded on photographic plates.
transition zone The region of rapid temperature increase that separates the Sun's chromosphere from the corona.
transverse motion Motion perpendicular to a particular line of sight, which does not result in Doppler shift in radiation received.
transit

transit: the meridian passage of a celestial body. This occurs when the body is directly south of the observer. It can also refer to the time of this occurrence. Transits may be either superior or inferior.
TRANSITION STATE - Maximas (peaks) on an energy diagram. A transition state represents the highest energy arrangement of atoms between two more stable forms.
Transit The passage of Mercury or Venus in front of the Sun's disc or the passage of a satellite or its shadow across the face of its primary.
Transit the meridian or meridian passage The passage of a heavenly body across the meridian.
Transition Region. The trasition region is the very narrow region of the solar atmosphere that separates the chromosphere and corona, where the temperature rises sharply from 20,000 to nearly a million Kelvin degrees.

The transition region is a thin and very irregular layer of the Sun's atmosphere that separates the hot corona from the much cooler chromosphere.
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.
Transit:
When a small celestial body moves in front of a much larger one (as when Mercury or Venus appears in silhouette against the solar disk or when a satellite passes in front of Jupiter or Saturn), the event is termed transit rather than eclipse.

Transits are the only time when you really have to think about a planet's declination - unless you are trying to be very precise in your understanding of the planet's motion and, like I said, we will come back to that in a few months.
Transit method: If a planet crosses (or transits) in front of its parent star's disk, then the observed brightness of the star drops by a small amount. The amount by which the star dims depends on its size and on the size of the planet.
TRANSIT
1. Transit is when a smaller body passes in front of a larger one (for example, when an object passes between the Sun and the Earth). During this time, the object seems to be crossing the disk of the Sun.
transit - An instrument for timing the exact instant a star or other objects crosses the local meridian. Also, the passage of a celestial body across the meridian; or the passage of a small body across the disk of a large one.
transit - (n.)
The passage of one celestial body in front of another celestial body. When a planet is in transit, we understand that it is passing in front of the sun.
transition elements - (n.) ...
The transition period from day to night (or night to day) when the sky is not completely dark, but the has not yet set (or risen).
The transit and microlens techniques are not good for looking planets around a particular star of interest. The star-wobble and direct imaging methods are better.
As the transit of Venus of 1874 approached, prepara tions were set on foot by the German Government in good time; a commission of the most celebrated astronomers was appointed, ...
Electron transitions in the Bohr model of the Hydrogen atom. As electrons jump down to the n = 2 orbit, they emit photons of specific frequency (hence colour) that can be seen as emission lines in the visible part of the em spectrum.
solar transition region (NASA Thesaurus) A layer of the solar atmosphere only a few hundred miles thick between the chromosphere and the corona across which the temperature rises rapidly from a few times 10(exp 4) K to the order of 10(exp 6) K.
A few molecular transitions can be pumped, either collisionally or by ambient ultraviolet radiation, to give astrophysical masers.

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.
