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 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 astronomers therefore suspect that it was once a comet.

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 people have luck and some have no luck and that, whatever people who prefer order say, is the size of it.

" Some prefer " America the Beautiful " over " The Star-Spangled Banner " due to the latter's war-oriented imagery.

Some bicycle parts, particularly hub-based gearing systems, are complex, and many cyclists prefer to leave maintenance and repairs to professional bicycle mechanics.

Some but not most Baptists prefer not to be called Protestants, claiming a direct ancestral line going back to the apostles in the 1st century.

Some doubt whether there is a unified cognitive science and prefer to speak of the cognitive sciences in plural.

Some authors of technical documents may prefer either mouse devices or the more generic pointing devices.

Some academics prefer to transliterate the term as Khalīfah.

Some dancers prefer to hold the arms much lower, similar to conventional ballroom positioning.

Some consumers prefer the taste of soda manufactured with sugar.

Some people also prefer to have the information on their tags transferred to a smaller, sometimes golden or silver tag by a jeweler, as the original tag can be considered too large and bulky by some.

Some forms of synthesis, like, for instance, sampling and additive synthesis are not feasible in analog synthesizers, while on the other hand, many musicians prefer the character of analog synthesizers over their digital equivalent.

Some prefer the Wade-based Taoism because it is more familiar than Daoism and because the borrowing is a fully assimilated English word anyway ; such words are generally unaffected by later systems of romanization.

Some theorists prefer to stick to Euclidean space and say that there is no dual.

Some Protestants prefer to call it an ordinance, viewing it not as a specific channel of divine grace but as an expression of faith and of obedience to Christ.

Some aficionados who prefer class-A amplifiers also prefer the use of thermionic valve ( or " tube ") designs instead of transistors, especially in Single-ended triode output configurations for several claimed reasons:

Some ' hard ' eurosceptics such as UKIP prefer to call themselves euro-realists rather than ' sceptics ', and regard their position as pragmatic rather than " in principle ".

Some proponents of spelling reform view homophones as undesirable and would prefer that they were eliminated.

Some noted brass pedagogues prefer to instruct the use of the embouchure from a less analytical point of view.

Some authors prefer to write all expressions covariantly.

Some luthiers prefer this method of construction as they claim it allows better sustain of each note.

Some veterinarians prefer radioiodine treatment over surgery because it does not carry the risks associated with anesthesia.

Some users prefer " C " style presses over " O " presses, as there is more room to place bullets into cartridge mouths on " C " presses.

Some prefer monogamous relationships for sex, and others may prefer many different partners throughout their lives
