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 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 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 believe the revision in question was the work of a single reviser, who in his changes and additions expressed the local interpretation put upon Acts in his own time.

Some expressed incomprehension or even hostility, varying from a rejection by the archaeological mainstream of what they saw as an archaeoastronomical fringe to an incomprehension between the cultural focus of archaeologists and the quantitative focus of early archaeoastronomers.

Some passengers expressed doubt that the bomb was real.

Some have recently expressed doubt to how much the theory was his.

Some Western scholars have expressed doubts over Laozi's historical existence, claiming that the Tao Te Ching is actually a collection of the work of various authors.

Some scientists and engineers have expressed reservations about nuclear power, including: Barry Commoner, S. David Freeman, John Gofman, Arnold Gundersen, Mark Z. Jacobson, Amory Lovins, Arjun Makhijani, Gregory Minor, Joseph Romm and Benjamin K. Sovacool.

Some special purpose languages such as Coq allow only well-founded recursion and are strongly normalizing ( nonterminating computations can be expressed only with infinite streams of values called codata ).

Some have expressed surprise that Heinz has responded to what they view as a small number of complainants, relative to the United Kingdom's 3. 6 million gay and lesbian consumers.

Some genes are found to be expressed from both maternal genomes while others are expressed exclusively from the lone paternal copy.

Some leading Conservatives ( e. g. Chancellor Ken Clarke ) favoured joining and insisted that Britain retain a completely free choice, whilst increasing numbers of others expressed their reluctance to join.

Some English players later expressed fears that a large-scale riot could break out and that the police would not be able to stop the irate home crowd, who were worried that Woodfull or Bradman could be killed, from attacking them.

Some theorists argue that the common language is not homogenizing ; and that there still remain strong differences expressed within the mass media.

Some say that there is no differentiation between the so-called internal and external systems of the Chinese martial arts, while other well known teachers have expressed differing opinions.

Some classical poetry forms, such as Venpa of the Tamil language, had rigid grammars ( to the point that they could be expressed as a context-free grammar ) which ensured a rhythm.

Anomie, variously expressed in the poetic terms of Hell's " Blank Generation " and the bluntness of the Ramones ' " Now I Wanna Sniff Some Glue ," is a common theme.

Some protestant writers have maintained that the " rock " that Jesus speaks of in this text is Jesus himself or the faith expressed by Peter.

Some classical Tamil poetry forms, such as veṇpā, have rigid grammars for rhyme to the point that they could be expressed as a context-free grammar.

Some in the literary community expressed disapproval of the award: Richard Snyder, the former CEO of Simon & Schuster, described King's work as " non-literature ", and critic Harold Bloom denounced the choice:

Some people, including Steven M. Greer, have expressed cynicism that the general public might not be informed in the event of a genuine discovery of extraterrestrial intelligence due to significant vested interests.
