Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ... Raw versions of real-time processing pictures FDS 0000984 and FDS 0000986 were used (images 196 and 202). ...

... Меркурий - четвертая по блеску планета: в максимуме она почти так же ярка, как Сириус, ярче же бывают только Венера, Марс, Юпитер. Тем не менее Меркурий очень трудная для наблюдения планета из-за малости его орбиты и, следовательно, близости к Солнцу; его наибольшая элонгация (видимое угловое расстояние от Солнца) составляет 28 градусов. ... Вследствие всех этих разного рода трудностей только самым упорным наблюдателям удавалось обнаружить детали на поверхности Меркурия. ...

ПЛАНЕТА ОЗИРИС . ... Озирис оказался первой экзопланетой, которая была исследована как с помощью метода доплеровской спектроскопии, когда измеряются небольшие смещения линий в спектре звезды, вызванные гравитационным влиянием планеты, так и с помощью наблюдения т.н. транзитов, т.е. проходов планеты по диску звезды. ... Озирис вращается вокруг звезды HD 209458 на расстоянии 0,045 а.е. или 6,75 млн км, что составляет менее 9 звездных радиусов. ... Озирис в Энциклопедии внесолнечных планет . ...

Больше всего ее на полюсах - а вот на солнечной стороне Луны воду почти не найти. ... По расчетам физиков, как минимум одна молекула воды из тысячи покидает поверхность Луны под воздействием ультрафиолета. ... Аналогично, устойчивый поток фотонов, падающих на Луну, уносит воду или повреждает ее молекулы. ...

... The greenhouse effect . ... The Earth receives short-wave radiation from the sun, one-third of which is reflected back out to space. The remaining radiation is absorbed by the surface and heats up the planet. Then the Earth emits infra-red radiation because of the greenhouse gases contained in the atmosphere. ... Problems arise when greenhouse gases such as carbon dioxide and methane increase due to human activities and the Earth gets hotter. ...
