Some amateur astronomers use home-made radio telescopes, while others use radio telescopes that were originally built for astronomy research but have since been made available for use by amateurs.

Some astronomers endeavoured to explain this by parallax, but these attempts were futile, for the motion was at variance with that which parallax would produce.

Some astronomers had suggested that the impacts might have a noticeable effect on the Io torus, a torus of high-energy particles connecting Jupiter with the highly volcanic moon Io.

Some notable observed features of galaxy structure ( including our own Milky Way ) that astronomers wish to explain with galactic formation theories include ( but are certainly not limited to ) the following:

Some astronomers prefer to refer to Sedna and 2000 CR < sub > 105 </ sub > as belonging to the " extended scattered disc " rather than to the inner Oort cloud.

Some astronomers believe the two types of star clusters form via the same basic mechanism, with the difference being that the conditions that allowed the formation of the very rich globular clusters containing hundreds of thousands of stars no longer prevail in the Milky Way.

Some astronomers expressed scepticism at the result.

Some astronomers explain this by presence of small temperature fluctuations within planetary nebulae ; others claim that the discrepancies are too large to be explained by temperature effects, and hypothesize the existence of cold knots containing very little hydrogen to explain the observations.

Some Greek astronomers considered them to be a distinct constellation, and they are mentioned by Hesiod, and in Homer's Iliad and Odyssey.

Some Greek astronomers ( e. g., Aristarchus of Samos ) speculated that the planets ( Earth included ) orbited the Sun, but the optics ( and the specific mathematics – Newton's Law of Gravitation for example ) necessary to provide data that would convincingly support the heliocentric model did not exist in Ptolemy's time and would not come around for over fifteen hundred years after his death.

Some of the other astronomers involved in the project include Wei-Chun Jao, John Subasavage and Thom Beaulieu of Georgia State University, Phil Ianna of the University of Virginia in Charlottesville, Hartmut Jahreiß of the Astronomisches Rechen-Institut in Heidelberg, Germany and Edgardo Costa and Rene Mendez of the Universidad de Chile.

Some astronomers use the term QSO ( Quasi-Stellar Object ) for this class of AGN, reserving ' quasar ' for radio-loud objects, while others talk about radio-quiet and radio-loud quasars.

Some astronomers put this down to the presence of small temperature fluctuations within H II regions ; others claim that the discrepancies are too large to be explained by temperature effects, and hypothesise the existence of cold knots containing very little hydrogen to explain the observations.

Some astronomers have estimated that there may be twice as many Jupiter-sized rogue planets as there are stars.

Some astronomers conjecture that its large mass may be related to its location near the Galactic Center, since the star formation process there may favor massive objects.

Some of these extrasolar planets are large and resemble Yavin, although astronomers cannot yet tell whether any Earth type planetary moons exist around such extrasolar planets.

Some astronomers believe that ring galaxies are formed when a smaller galaxy passes through the center of a larger galaxy.

Some amateur astronomers use their telescopes the same way, but direct optical viewing with eyepieces is still very common.

Some astronomers, however, prefer to specify the resulting magnification power rather than the focal length.

Some astronomers now agree that Dr. Stuart may indeed have photographed an asteroid impact on the Moon.

Some elements of Indian astronomy reached China with the expansion of Buddhism after the Eastern Han Dynasty ( 25 – 220 AD ), but the most detailed incorporation of Indian astronomical thought occurred during the Tang Dynasty ( 618-907 ), when numerous Indian astronomers took up residence in the Chinese capital, and Chinese scholars, such as the great Tantric Buddhist monk and mathematician Yi Xing, mastered its system.

Some astronomers have argued that Thule's present orbit is the natural result of the force of Jupiter on a body orbiting at precisely the distance from the Sun Thule does, in the same way ( though with the reverse effect ) as the Kirkwood gaps in the more inner parts of the asteroid belt.

Some astronomers suggested that perhaps they were all one comet, whose orbital period was somehow being drastically shortened at each perihelion passage, perhaps by retardation by some dense material surrounding the Sun.

Some sidewalk " pitch men " charged the public to view astronomical objects through their telescope but other astronomers allow people to view for free.

Some Anglicans accept that anointing of the sick has a sacramental character and is therefore a channel of God's grace, seeing it as an " outward and visible sign of an inward and spiritual grace " which is the definition of a sacrament.

Some operations may change the state of the ADT ; therefore, the order in which operations are evaluated is important, and the same operation on the same entities may have different effects if executed at different times — just like the instructions of a computer, or the commands and procedures of an imperative language.

Some mathematicians, especially in set theory, do not consider the sets and to be part of the relation, and therefore define a binary relation as being a subset of x, that is, just the graph.

Public discourse ranged in tone from organized arguments by tobacconist and medical practitioner John Williams, who posited that " several arguments proving that inoculating the smallpox is not contained in the law of Physick, either natural or divine, and therefore unlawful ," to more slanderous attacks, such as those put forth in a pamphlet by Dr. William Douglass of Boston entitled The Abuses and Scandals of Some Late Pamphlets in Favour of Inoculation of the Small Pox ( 1721 ), on the qualifications of inoculation's proponents.

Some experiences were therefore rejected out of hand, and some unpleasant experiences endured in the present to ensure a better life in the future.

Some critics, such as Jerry Coyne ( professor of evolutionary biology at the University of Chicago ) and Eugenie Scott ( a physical anthropologist and executive director of the National Center for Science Education ) have argued that the concept of irreducible complexity, and more generally, intelligent design is not falsifiable, and therefore, not scientific.

Some Kuwaitis are originally from Persia and other non-Arab countries, however, they assimilated with the Arabs of Kuwait after acquiring Kuwaiti citizenship and are therefore Arabized Arabs.

Some followers of Marx concluded, therefore, that a communist revolution would inevitably occur.

Some North American fans, already attached to particular spellings, took great umbrage at Schodt's renditions, forgetting that in the original Japanese most character and mecha names are written in katakana, and that there were, therefore, no " official spellings.

Some people use the phrase " naturalistic fallacy " or " appeal to nature " to characterize inferences of the form " This behaviour is natural ; therefore, this behaviour is morally acceptable " or " This property is unnatural ; therefore, this property is undesireable.

Some physicists have explored the notion that if the dimensionless physical constants had sufficiently different values, our Universe would be so radically different that intelligent life would probably not have emerged, and that our Universe therefore seems to be fine-tuned for intelligent life.

Some historians, mainly of the late 19th century and before, therefore speculated ( on no evidence ) that he must have traveled overland to the mouth of the Loire or the Garonne.

Some have argued that logic dictates, therefore, that the jar acts as a prison for Elpis as well, withholding it from men.

Some pollutants are biodegradable and therefore will not persist in the environment in the long term.

Some historians, social scientists and anthropologists have, however, argued that their disciplines already describe psychological motivation and that Psychohistory is not, therefore, a separate subject.

Some of the sources say that Descartes denied the animals could feel pain, and therefore could be used without concern.

Some manufacturers therefore built transmitters that supplied + 5 V and-5 V and labeled them as " RS-232 compatible ".

Some philosophers see language as representing directly entities that already exist in the objective world, and that categorization is therefore not generally variable but to some extent pre-given.

Some, therefore, of the miserable remnant, being taken in the mountains, were murdered in great numbers ; others, constrained by famine, came and yielded themselves to be slaves for ever to their foes, running the risk of being instantly slain, which truly was the greatest favour that could be offered them: some others passed beyond the seas with loud lamentations instead of the voice of exhortation ... Others, committing the safeguard of their lives, which were in continual jeopardy, to the mountains, precipices, thickly wooded forests, and to the rocks of the seas ( albeit with trembling hearts ), remained still in their country.

Some in the UFO community, such as nuclear physicist Stanton Friedman, say there is no basis for the search and it is therefore unscientific.

Some scenes of the Mesolithic, however, can be typed and therefore, judging from their various modifications, are fairly clear.

Some, like Louis Jacobs, argue that the main body of the Gemara is not simple reportage of conversations, as it purports to be, but a highly elaborate structure contrived by the Saboraim, who must therefore be regarded as the real authors.

Some scholars therefore believe that it is an interpolation, while others have argued that it is original.

Some critics were dissatisfied by his choice of poem order and omissions in the book and some feminists argued that Hughes had essentially driven her to suicide and therefore should not be responsible for her literary legacy.
