Zenith (building)

The Zenith is a culture and exhibition centre, converted from an old railway reparation hall, located in Freimann, Munich, Germany.

The centre hosts concerts, fairs, company presentations and parties. The centre can hold up to six thousand people and has a floor area of 5046 m². The main stage is 24×16 metres in area. Its capacity is approximately 7,000 people

History

The building is of a unique architectural style, and formerly served as a railway construction and reparation hall. It was originally built from 1916 to 1918. The building is protected.

Zenith camera

A zenith camera is an astrogeodetic telescope used today primarily for the local surveys of Earth's gravity field. Zenith cameras are designed as transportable field instruments for the direct observation of the plumb line (astronomical coordinates) and vertical deflections.

Instrument

A zenith camera combines an optical lens (about 10–20 cm aperture) with a digital image sensor (CCD) in order to image stars near the zenith. Electronic levels (tilt sensors) serve as a means to point the lens towards zenith. Zenith cameras are generally mounted on a turnable platform to allow star images to be taken in two camera directions (two-face-measurement). Because zenith cameras are usually designed as non-tracking and non-scanning instruments, exposure times are kept short, at the order of few 0.1 s, yielding rather circular star images. Exposure epochs are mostly recorded by means of the timing-capability of GPS-receivers (time-tagging).

Data processing

Depending on the CCD sensor - lens combination used, few 10s to 100s of stars are captured with a single digital zenith image. The positions of imaged stars are measured by means of digital image processing algorithms, such as image moment analysis or point spread functions to fit the star images. Star catalogues, such as Tycho-2 or UCAC-3 are used as celestial reference to reduce the star images. The zenith point is interpolated into the field of imaged stars, and corrected for the exposure time and (small) tilt of the telescope axis to yield the direction of the plumb line.

Zenith (disambiguation)

The zenith is the point in the sky that appears directly above the observer (opposite: nadir).

Phil Fearon

Phil Fearon (born 30 July 1956) is an English record producer. He was the lead singer, songwriter and multi-instrumentalist for the 1980s band Galaxy.

Career

Fearon was born in Jamaica in 1956, but moved to London with his parents at the age of five. After running a reggae sound system, he joined Hott Wax (which evolved into Brit funk pioneers Hi-Tension after he left) and in the late 1970s was a mainstay of hit group Kandidate which scored a number 11 chart hit in 1979 with "I Don't Wanna Lose You". He set up a studio in his north London house and initially recorded with the group Proton on Champagne Records. Fearon’s first recording as Galaxy (with assistance from singers Julie and Dorothy) was "Head Over Heels" on Ensign Records in 1982, which became a club hit. The first success came with the Top 5 hit "Dancing Tight" in 1983 and over the next 15 months they chalked up a further four UK Top 40 singles including the Top 10s "What Do I Do" and "Everybody’s Laughing". Their radio-friendly pop/soul debut album, Phil Fearon & Galaxy also made the Top 10 in 1984. After a quiet period, Fearon returned to the Top 10 for the last time with a revival of Tony Etoria’s "I Can Prove It" in 1986 (also a minor US R&B hit). He continued to run a production company from his home making commercial dance records.

Galaxy (spacecraft)

Galaxy (previously Guardian) is a canceled prototype space habitat designed by the American firm Bigelow Aerospace, and was intended to be the third spacecraft launched by the company in their efforts to create a commercial space station. Like other modules made by Bigelow Aerospace, Galaxy is based on the inflatable TransHab design by NASA, and was to be used for advanced systems testing before the company launched human-rated vehicles.

Spacecraft history

Galaxy started life as twin spacecraft named Guardian which would have acted as 45% scale intermediates between the one-third size Genesis I & Genesis II pathfinders and the full size BA 330 man-rated module. Sometime after 2004, the two Guardian flights were split into the Galaxy module and larger Sundancer module, each testing progressively advanced systems. This Galaxy had twice the interior volume of the Genesis craft: 23.0 cubic meters (812.2 cu ft). In 2007, the parameters for Galaxy were again modified, with final specifications being for a spacecraft 4.0 meters (13.1 ft) in length, 3.3 meters (10.8 ft) in diameter and with 16.7 cubic meters (589.8 cu ft) of interior volume—45% greater than the Genesis modules. It was intended for launch in late 2008.

Galaxy is the seventh studio album by The Jeff Lorber Fusion it was released in January.
