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 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 45 frequencies are assigned for use primarily by dominant Class 1, -- A or Class 1, -- B clear-channel stations, designed to operate with adequate power and to provide service -- both groundwave and ( at night ) skywave -- over large areas and at great distances, being protected against interference to the degree necessary to achieve this objective.

Some cases in evidence of the use of roleplaying for analysis may help explain the procedure.

Some of Thurber's curative methods involve strong potions of mixed metaphor, malapropism, and gobbledygook and are recommended for use only in extreme cases.

Some popular designs use the following types of ANOVA:

Some sources mention the use of an abacus called a nepohualtzintzin in ancient Mayan culture.

Some adaptations of the Latin alphabet are augmented with ligatures, such as æ in Old English and Icelandic and Ȣ in Algonquian ; by borrowings from other alphabets, such as the thorn þ in Old English and Icelandic, which came from the Futhark runes ; and by modifying existing letters, such as the eth ð of Old English and Icelandic, which is a modified d. Other alphabets only use a subset of the Latin alphabet, such as Hawaiian, and Italian, which uses the letters j, k, x, y and w only in foreign words.

Some may suggest that it is probably advisable to use mouthwash at least an hour after brushing with toothpaste when the toothpaste contains sodium lauryl sulfate, since the anionic compounds in the SLS toothpaste can deactivate cationic agents present in the mouthrinse.

Some results in constructive set theory use the axiom of countable choice or the axiom of dependent choice, which do not imply the law of the excluded middle in constructive set theory.

Some abugidas use a special symbol to suppress the inherent vowel so that the consonant alone can be properly represented.

Some modern descendants of this culture often choose to use the term " Ancestral Pueblo " peoples.

Some of the Australians wanted to use Bodyline in retaliation, but Woodfull flatly refused.

Some hard science fiction stories use small ( possibly nano-sized ) paired wormholes dedicated to communication by means of a laser which traverses the wormhole.

( Some newer protocols, such as Kerberos and Active Directory use DNS SRV records to identify services by name, which is much closer to the AppleTalk model.

Some consider such use of the term " incorrect.

Some natural tolerance to habitual use of ayahuasca ( roughly once weekly ) may develop through upregulation of the serotonergic system.

Some reports and scientific studies affirm that ritualized use of ayahuasca may improve mental and physical health.

Some Protestant US military chaplains carry the Roman Rite version of the Anointing of the Sick with them for use if called upon to assist wounded or dying soldiers who are Catholics.

Some Nasheed singers avoid instruments in the background due to the opinion of certain scholars that their use is prohibited.

Some guns were suitable for dual-role anti-aircraft and field ( anti-tank ) use.

Some studies have found decreased life expectancy associated with the use of antipsychotics, and argued that more studies are needed.

Some doubts have been raised about the long-term effectiveness of antipsychotics for schizophrenia, in part because two large international World Health Organization studies found individuals diagnosed with schizophrenia tend to have better long-term outcomes in developing countries ( where there is lower availability and use of antipsychotics and mental health problems are treated with more informal, community-led methods only ) than in developed countries.

Some critics have also analyzed the use of alleged front organizations and conflicted patient " advocacy " groups funded by pharmaceutical companies that seek to set the mental health agenda, including the use of the law to force people to take antipsychotics against their will, often justified by claims about risk of violence.
