PIX4669127: Dial of the Tower of the Clock - Auxerre - Clock on the clock tower in Auxerre - Clock with dials of the Tower of the Clock in Auxerre. This public clock was built in 1469 by a master watchmaker named Jean. It operated until 1812. The present mechanism dates back to 1817. The clock consists of two identical dials, one to the east (photo), the other to the west. The dials are divided into 24 hours: from noon to midnight, and from midnight to noon. A needle on which the Sun is depicted indicates the hours of the day. The second hand carries a globe with half black and half gold. This globe indicates the phases of the Moon. This needle indicates the lunar day, which is 24h49min. The stars pass to the Meridian (towards the south) when their image is at the top of the dial, on the number XII.

PIX4669179: The Earth and the Moon seen from space as it could appear from a satellite place at 35,000 km altitude. Composite image based on GOES (Geostationary Operational Environmental Satellite) data for clouds and Terra satellite for surface - This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth. The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Nasa's Terra satellite collected the land surface data over 16 days, while Noaa's Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth's clouds: Earth seen by satellite - Earth seen by satellite / Bridgeman Images
PIX4671658: Paraselene on a full moon night - Moon dog - A paraselene consists of light spots located on the left and right at the height of the Moon; they are equivalent to the parhelies of the Sun. These glowing patch is named Moon dog. Moon dogs are the same phenomenon as the sun dogs for the Sun / Bridgeman Images

These glowing patches on the right and left at the Moon's elevation are named Moon dog. Moon dogs are the same phenomenon as the sun dogs for the Sun / Bridgeman Images
PIX4671758: Halo and Light Column- Ice halos near Zeel am See, Austria - A light column is created by the reflection of a light source on the horizontal faces of ice crystals. So it takes a fairly stable atmosphere to keep these crystals parallel to the horizon. Lunar halo. The ice crystals in the cirrus decompose the lunar light (in fact, the solar light reflected by the lunar surface) as small prisms and can give rise to a large coloured circle. A paraselene consists of light spots located on the left and right at the height of the Moon. Austria, January 2016. A light pillar is created by the reflection of light on the horizontal face of ice cristals. So, a quiet atmosphere is needed in order that this cristals stay parallel to the horizon. Lunar halos are caused by moonlight being refracted by cirro-stratus clouds. These thin clouds are located very high in the atmosphere, and are composed of ice crystals. They bend light at a 22 degree angle, which creates a halo that is 44 degrees in diameter / Bridgeman Images
PIX4671763: Corona around the Moon - Corona around the Moon - When the light of the Moon passes through thin clouds of water droplets, it can create a moon crown of color. In meteorology, a lunar corona is produced by the diffraction of light from the Moon by small water droplets in a cloud / Bridgeman Images
PIX4653005: The Sun and Moon on Cerro Armazones - Sun and Moon on Cerro Armazones - 360-degree panorama showing the meteorological station at the top of Cerro Armazones. This 3060-metre mountain in Chile will host the giant telescope E - ELT (European Extremely Large Telescope). The construction of this 42-metre telescope is expected to start at the end of 2010 and will be inaugurated around 2018. Its main mirror will consist of 906 hexagonal mirrors assembled together, and its total surface will be equal to that of a football field. This sunset 360 degree panorama shows the ESO Astronomical Site Monitor on Cerro Armazones in the Chilean desert, near Eso's Paranal Observatory, site of the Very Large Telescope (VLT). Cerro Armazones was chosen as the site for the planned European Extremely Large Telescope (E - ELT), which, with its 42 - metre diameter mirror, will be the world's biggest eye on the sky / Bridgeman Images
PIX4571471: A comete approaches the Sun - Illustration - Comet near our Sun - artwork - Artist's view of the comete McNaught near the Earth and the Sun eclipse through the Moon. Comet Mcnaught makes its close approach to Earth in early 2007. It is New Moon and we are situated in a position above Earth where the moon eclipses the sun / Bridgeman Images
