Although, as of 2009, none of the extrasolar planets detected by ground-based astrometry has been verified in subsequent studies, astrometry is expected to be more accurate in space missions that are not affected by the distorting effects of the Earth's atmosphere.

Although Cetus is not generally considered part of the zodiac, the ecliptic passes close to its constellation boundary, and thus the planets may be seen in Cetus for brief periods of time.

Although both planets orbit their central star ( as depicted in Star Trek Nemesis ), Romulus and Remus are often referred to as a double planet.

Although we have not traveled to all the planets nor to the Sun, we know their masses.

Although it is known today that the planets revolve around the sun, the same terms continue to be used in order to describe the movement of the planets in relation to the stars as they are observed from Earth.

Although many other planets make that claim, Comporellon has a very long history with which to back it up.

Although Ptolemy relied mainly on the work of Hipparchus, he introduced at least one idea, the equant, which appears to be his own, and which greatly improved the accuracy of the predicted positions of the planets.

Although this system was not chosen as a primary candidate for the now-canceled Terrestrial Planet Finder, it was a target star for NASA's proposed Space Interferometry Mission to search for Earth-sized planets.

Although not clear from Kardec's works, later spiritist writers elaborated on this point further, claiming humanity cannot detect more advanced life forms on other planets, as they are living in a slightly different plane, in the same way the spiritual plane is superimposed over this plane.

Although some planets would resist the harvest fleet, they could never stop it.

Although no planets in the Solar System are completely tidally locked, planets with regular orbits in close to their primary stars are thought to typically experience tidal locking.

Although the models of Eudoxus and Callippus qualitatively describe the major features of the motion of the planets, they fail to account exactly for these motions and therefore cannot provide quantitative predictions.

Although polar cores have the clearest and longest chronological record, four-times or more as long, ice cores from tropical regions offer data and insights not available from polar cores and have been very influential in advancing understanding of the planets climate history and mechanisms.

Although planets and stars are neither in thermal equilibrium with their surroundings nor perfect black bodies, black body radiation is used as a first approximation for the energy they emit.

Although the solar chart is deficient in that it cannot show the ascendant, midheaven or the houses with any accuracy, it can neverthelss provide a fairly accurate profile of a person's character from examining the position of the planets alone.

Although they are forbidden to sit with the customers, the dancers are sometimes proffered drinks, and most of them can bolt one down in mid-shimmy.

Although the Af calculation is obvious by analogy with that for gravitational field and osmotic pressure, it is interesting to confirm it by a method which can be generalized to include related effects.

Although no national norms exist for the social development of children, the teacher can find a great deal of information concerning types of social behavior normally displayed by children at various age levels.

Although the first polyether foams on the market had to be produced by the two-step prepolymer method, today, thanks to new catalysts, they can be produced by a one-shot technique.

Although a complete picture cannot be given, we can indicate some aspects of life into which the Christian faith entered as at least one creative factor.

Although human morphology is not necessarily the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra ( devices that exhibit likeness ) and automata ( devices that have independence ).

Although digital setting circles can be used to display a telescope's RA and Dec coordinates, they are not simply a digital read-out of what can be seen on the telescope's analog setting circles.

Although the neutral ground-state chemical compounds of argon are presently limited to HArF, argon can form clathrates with water when atoms of it are trapped in a lattice of the water molecules.

Although hydrogen-like orbitals are still used as pedagogical tools, the advent of computers has made STOs preferable for atoms and diatomic molecules since combinations of STOs can replace the nodes in hydrogen-like atomic orbital.

Although not as accurate by themselves as STOs, combinations of many Gaussians can attain the accuracy of hydrogen-like orbitals.

Although the terms adiabatic and isocaloric can often be interchanged, adiabatic processes may be considered a subset of isocaloric processes ; the remaining complement subset of isocaloric processes being processes where net heat transfer does not diverge regionally such as in an idealized case with mediums of infinite thermal conductivity or non-existent thermal capacity.

Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks.

Although programs can alter the position of the screen in memory, the non-linear format of the display means that vertical scrolling can only be done in blocks of 8 pixels without further work.

Although such a conversion can be prone to loss, most modern audio systems use this approach as the techniques of digital signal processing are much more powerful and efficient than analog domain signal processing.

Although sometimes this energy is released in the form of an emitted photon, the energy can also be transferred to another electron, which is ejected from the atom.

* Conservation of Energy: Although energy can be converted from one form to another, the total energy in a given closed system remains constant.

Although colors can be mixed, pigments are often not specified.

Although some plants do prefer slightly basic soil ( including vegetables like cabbage and fodder like buffalograss ), most plants prefer a mildly acidic soil ( pH between 6. 0 and 6. 8 ), and alkaline soils can cause problems.

Although AVMs are often associated with the brain and spinal cord, they can develop in any part of the body.

Although oxidation reactions are crucial for life, they can also be damaging ; plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxidases.

Although integration is the primary purpose of these organizations, they also serve as forums in which Brazil can exercise its leadership and develop consensus around its positions on regional and global issues.

Although black is sometimes described as an " achromatic ", or hueless, color, in practice it can be considered a color, as in expressions like " black cat " or " black paint ".
