Another reflection on the stars by a writer who loves the wild places where dark skies are more likely, the stars more visible. Robert Macfarlane is moved, almost physically, by gazing up - or is it down? into the night sky. The unconverted and limitless nature of the night sky ... is given a depth by the stars that far exceeds the depth given to the diurnal sky by clouds. On a cloudless night, looking upwards, you experience a sudden flipped vertigo, the feeling that your feet might latch off from the earth and you might plummet upwards into space... Our estrangement from the dark [due to street lighting] was a great and serious loss. Robert Macfarlane, THE WILD PLACES, London, Granta, 2007. A similar emotion struck David, who must have spent many a night under the stars: For I will behold thy heavens, the works of thy fingers: the moon and the stars which thou hast founded. What is man that thou art mindful of him? or the son of man that thou visitest him? Thou hast made him a little less than the angels, thou hast crowned him with glory and honour: And hast set him over the works of thy hands. Psalm 8:4-7
Before we get carried away in gratification, let Macfarlane remind us that the loss of the night sky to urban dwellers is serious and stunting.
About the photograph: Image of the night sky above Paranal, Chile on 21 July 2007, taken by ESO astronomer Yuri Beletsky. A wide band of stars and dust clouds, spanning more than 100 degrees on the sky, is seen. This is the Milky Way, the galaxy to which we belong. At the centre of the image, two bright objects are visible. The brightest is the planet Jupiter, while the other is the star Antares. Three of the four 8.2-m telescopes forming ESO’s VLT are seen, with a laser beaming out from Yepun, Unit Telescope number 4. The laser points directly at the Galactic Centre. Also visible are three of the 1.8-m Auxiliary Telescopes used for interferometry. They show small light beams which are diodes located on the domes. The exposure time is 5 minutes and because the tracking was made on the stars, the telescopes are slightly blurred.
