Among some amateur astronomers, NGC 246 has garnered the nickname " Pac-Man Nebula " because of the arrangement of its central stars and the surrounding star field.

It has an overall magnitude of 8. 0 and a central star of magnitude 11. 0 ; it is 2600 light-years from Earth.

The light from the central star was blanked out by a vector vortex coronagraph.

The central blob is noise left over after light from the star has been largely removed.

Its central star is of magnitude 11. 4, an unusually bright specimen.

The black central circle is produced by the camera's coronagraph, which hides the central star to allow the much fainter disks to be seen.

The hottest region, closest to the central star, appears blue because of emission from helium.

The central star itself is a white dwarf with a temperature of 120, 000 degrees Kelvin.

When it was pointed out to Niven that the Ringworld was dynamically unstable, in that once the center of rotation drifted away from the central sun, gravity would pull the ring into contact with the star, he used this as a plot element in the sequel novel, The Ringworld Engineers.

With his roles in Leone's films, Van Cleef became a major star of Spaghetti Westerns, playing central roles in films such as Death Rides a Horse, Day of Anger, The Big Gundown and The Sabata Trilogy.

The PPN is energized by the central star, causing it to emit strong infrared radiation and become a reflection nebula.

Collaminated stellar winds from the central star shape and shock the shell into an axially symmetric form, while producing a fast moving molecular wind .< ref name = mnras360_1 > The exact point when a PPN becomes a planetary nebula ( PN ) is defined by the temperature of the central star.

The PPN phase continues until the central star reaches a temperature of 30, 000 K, after which is it hot enough to ionize the surrounding gas.

The badge of the Presidential Medal of Freedom is in the form of a golden star with white enamel, with a red enamel pentagon behind it ; the central disc bears thirteen gold stars on a blue enamel background ( taken from the Great Seal of the United States ) within a golden ring.

A special grade of the medal, known as the Presidential Medal of Freedom with Distinction, has a larger execution of the same medal design worn as a star on the left chest along with a sash over the right shoulder, with its rosette ( blue with white edge, bearing the central disc of the medal at its center ) resting on the left hip.

Although both planets orbit their central star ( as depicted in Star Trek Nemesis ), Romulus and Remus are often referred to as a double planet.

With the high infrared energy input from the central star, ideal conditions are formed in these circumstellar envelopes for maser excitation.

In its simplest form, a star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages.

An active star network has an active central node that usually has the means to prevent echo-related problems.

The star topology reduces the chance of network failure by connecting all of the systems to a central node.

Third, there were those ( notably Patrice Lumumba ) who favored a unified Congo with a very strong central government.

Our endeavor to capture even a faint sense of how strenuous was the fight is muffled by our indifference to the very issue which in the Boston of 1848 seemed to be the central hope of its Christian survival, that of the literal, factual historicity of the miracles as reported in the Four Gospels.

Only then in fact was payment for assembly attendance, the central event of democracy ( Similarly for the period before the Persian wars, but for the very early democracy the sources are very meagre and it can be thought of as being in an embryonic state ).

The intense secrecy surrounding the base, whose very existence the U. S. government did not even acknowledge until 29 September 1995, has made it the frequent subject of conspiracy theories and a central component to unidentified flying object ( UFO ) folklore.

On icy as opposed to rocky bodies, other morphological forms appear which may have central pits rather than central peaks, and at the largest sizes may contain very many concentric rings – Valhalla on Callisto is the type example of the latter.

The power of making by-laws was “ tacitly annexed to corporations by the very act of their establishment .” While they must not directly contradict the overarching laws of the land, the central or local government cannot be expected to regulate toward the peculiar circumstances of a given body, and so “ they are invested with authority to make regulations for the management of their own interests and affairs .”

By adopting the name Chung-cheng (" central uprightness "), he was choosing a name very similar to the name of Sun Yat-sen, who was ( and still is ) known among Chinese as Zhongshan ( 中山 — meaning " central mountain "), thus establishing a link between the two.

Another method is simply to release no data at all, except very large scale data directly to the central government.

In 1960, the country was in a very unstable state — regional tribal leaders held far more power than the central government — and with the departure of the Belgian administrators, there were almost no skilled bureaucrats left in the country.

straddles Equator ; very narrow strip of land that controls the lower Congo River and is the only outlet to South Atlantic Ocean ; dense tropical rainforest in central river basin and eastern highlands

This system though is not very reliable and lacks discipline, the high number of public cars that transit the roads, and the fact that they do not lend itself to regulation or central control, which causes frequent transit problems among city roads.

Nevertheless, the subsequent achievements of proof theory at the very least clarified consistency as it relates to theories of central concern to mathematicians.

By World War I drum kits were characterized by very large bold marching bass drums and many percussion items suspended on and around them, and they became a central part of jazz music, specifically ( but not limited to ) dixieland.

The central dispute in the letter concerns the question of how Gentiles could convert to Christianity, which shows that this letter was written at a very early stage in church history, when the vast majority of Christians were Jewish or Jewish proselytes, which historians refer to as the Jewish Christians.
