• The skies abruptly lowered on us.

  • Additionally, colour constancy in the visual system recalibrates the relations between the colours of an object and its surroundings, and since the surrounding sky is comparatively dark, the sunlit Moon is perceived as a bright object.

  • Allison's theory worked, with City winning the 1969 FA Cup Final, 1970 League Cup Final and the 1970 European Cup Winners' Cup Final in red and black stripes as opposed to the club's home kit of sky blue.

  • Another hypothesis argues that long-period comets, rather than arriving from random points across the sky as is commonly thought, are in fact clustered in a band inclined to the ecliptic.
  • Wikipedia: Planets beyond Neptune
  • As the region of sky close to the ecliptic became well explored, later sky surveys began looking for objects that had been dynamically excited into orbits with higher inclinations, as well as more distant objects, with slower mean motions across the sky.

  • Astronomers have calculated that such an object so close to Earth would be visible to anyone looking up at the night sky.

  • By contrast, at the major population centers of the northern temperate latitudes, Mercury is never above the horizon of a more-or-less fully dark night sky.

  • Deep sky surveys show that galaxies are often found in relatively close association with other galaxies.

  • During the infiltration, Vaan encounters Balthier and Fran, a pair of sky pirates who are after the magicite that Vaan took from the royal treasury.

  • Each pixel on the WFPC2 CCD chips recorded an area of sky 0.09 arcseconds across, but by changing the direction in which the telescope was pointing by less than that between exposures, the resulting images were combined using sophisticated image-processing techniques to yield a final angular resolution better than this value.

  • Finally, the background sky is darker in space than on the ground, because air absorbs solar energy during the day and then releases it at night, producing a faint—but nevertheless discernible—airglow that washes out low-contrast astronomical objects.

  • Folklore often identifies a green sky with tornadoes, and though the phenomenon may be associated with severe weather, there is no evidence linking it specifically with tornadoes.

  • For a finale, to the close the Games, the lights were extinguished and a 20-minute fireworks display lit up the night sky.

  • Hence, prior to the invention of the telescope, nothing was known about the planet besides its position on the sky.

  • However, better measurements of cosmological parameters through deep sky surveys and satellites such as COBE have resolved this issue as have computer models of stellar evolution that have different models of mixing.

  • Hyakutake was moving so rapidly across the night sky that its movement could be detected against the stars in just a few minutes; it covered the diameter of a full moon (half a degree) every 30 minutes.

  • Ideally, the sky should be very clear, with the observer at a high altitude, the star passing overhead, and the Sun low down on the horizon.
  • Wikipedia: Sirius
  • If three-quarters or more of the sun is obscured, then an effect can be observed by which the daylight appears to be dim, as if the sky were overcast, yet objects still cast sharp shadows.

  • In 2005 a rotating 15-foot (4.6 m) slotted observatory dome, two 12-foot (3.7 m) clamshell domes, and a 10-by-12-foot (3.0 by 3.7 m) sky shed were added, as well as a small amphitheater for programs.

  • In addition, detailed planning had been dislocated by the voluntary German withdrawal to the Hindenburg Line, secrecy had been compromised, and German planes gained control of the sky making reconnaissance difficult.

  • In interstellar astronomy, visible spectra can appear redder due to scattering processes in a phenomenon referred to as interstellar reddening — similarly Rayleigh scattering causes the atmospheric reddening of the Sun seen in the sunrise or sunset and causes the rest of the sky to have a blue color.

  • In the cult of the sun god Ra, for instance, hymns were sung day and night for every hour of the god's journey across the sky.

  • It is an enormous – 192.4 by 62.2 arcminutes in apparent size – barred spiral galaxy similar in form to the Milky Way and at an approximate magnitude of 3.5, is one of the brightest deep-sky objects in the northern sky.
  • Wikipedia: Andromeda (constellation)
  • It is visible to the naked eye in the night sky and can occasionally be seen in the daytime when the sun is low.

  • Nearby stars often have a relatively high proper motion, so astrometric binaries will appear to follow a sinusoidal path across the sky.

  • On 11 July 2011, Neptune completed its first full barycentric orbit since its discovery in 1846, although it did not appear at its exact discovery position in our sky because the Earth was in a different location in its 365.25-day orbit.
