Images captured of RAF Fylingdales on the Yorkshire Moors.
RAF Fylingdales is a small unit on the North Yorkshire Moors and was first declared operational in 1963 as one of 3 radar sites in the Ballistic Missile Early Warning System (BMEWS), the other 2 sites being in Alaska and Greenland.
The site was originally dominated by 3 ‘Golf Balls’ which housed mechanical tracking radars. In the early 1990s, the old radars were replaced by a much more capable Solid State Phased Array Radar (SSPAR), which underwent another upgrade completed in 2007.
The SSPAR was built by Raytheon and consists of a 3-sided truncated pyramid about 120 feet (40m) high. Each face is approximately 84 feet (28m) in diameter and contains an array of 2,560 transmit/receive modules, each with a circularly polarised ‘Pawsey Stub’ antenna. Each antenna has a power output of 340 watts and this gives an overall mean power output from the 3 faces of approximately 2.5 Mega Watts. The SSPAR has no big dishes that turn, indeed no moving parts at all. Instead, the SSPAR uses changes in electrical phase to steer the radar beam.
Each of the 2,560 transmitters on a face can send out its pulse at a slightly different time – or more correctly in a different phase. These pulses combine together to form a wavefront which can be effectively pointed in any direction simply by altering the timing, or phasing, of the 2,560 transmitters. Although the use of this ‘phased array’ principle is well known and many radars now use this technique, Fylingdales is the only 3-faced BMEWS radar in the world, providing a full 360º of cover.
The SSPAR can keep track of many hundreds of space objects per minute out to a range of 3000 nautical miles. The radar software is designed to ignore targets that do not behave like a rocket being launched or a satellite in orbit.

Im really glad that I captured this because at the strip of las vegas we barely see birds flying thru and the sun was setting just perfect timing.

My daughter spotted this rather large Carolina Wolf Spider (Hogna carolinensis) in the yard today! She was injured, and missing a leg. After a VERY brief photo shoot, we relocated her to my tea corner. She should have an easier time hunting aphids and other soft bodies insects over there. Captured using my Vivitar 90mm f2.8 Macro, along with 49mm of extension tubes and a slave flash in a bracket to the side of my lens. Getting good results from this cheap setup, and I'm pleased as punch!

Note: The adjacent star-like object is likely Neptune's largest moon Triton. Max separation is 9-16 arcsec and apparent magnitude is +13.5. Triton orbits Neptune every 5.9 days. Neptune has 14 known moons. Also, the haze around the globe in the image is most likely an artifact, vice the faint ring system.
from Wikipedia
Neptune is the eighth and farthest-known planet from the Sun. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, slightly more massive than its near-twin Uranus. Neptune is denser and physically smaller than Uranus because its greater mass causes more gravitational compression of its atmosphere. The planet orbits the Sun once every 164.8 years at an average distance of 30.1 AU (4.5 billion km; 2.8 billion mi). It is named after the Roman god of the sea and has the astronomical symbol ♆, a stylized version of the god Neptune's trident.
Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. After Bouvard's death, the position of Neptune was predicted from his observations, independently, by John Couch Adams and Urbain Le Verrier. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 13 known moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989; Voyager 2 remains the only spacecraft to visit Neptune. The advent of the Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
Like Jupiter and Saturn, Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, though it contains a higher proportion of "ices" such as water, ammonia and methane. However, similar to Uranus, its interior is primarily composed of ices and rock; Uranus and Neptune are normally considered "ice giants" to emphasize this distinction. Traces of methane in the outermost regions in part account for the planet's blue appearance.
In contrast to the hazy, relatively featureless atmosphere of Uranus, Neptune's atmosphere has active and visible weather patterns. For example, at the time of the Voyager 2 flyby in 1989, the planet's southern hemisphere had a Great Dark Spot comparable to the Great Red Spot on Jupiter. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 km/h (580 m/s; 1,300 mph). Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (−218 °C; −361 °F). Temperatures at the planet's centre are approximately 5,400 K (5,100 °C; 9,300 °F). Neptune has a faint and fragmented ring system (labelled "arcs"), which was discovered in 1984, then later confirmed by Voyager 2.
