  2. Messier 75 - Wikipedia

    en.wikipedia.org/wiki/Messier_75

    Messier 75 is part of the Gaia Sausage, the hypothesized remains of a dwarf galaxy that merged with the Milky Way. [10] It is a halo object with an orbital period of 0.4 billion years to travel around the galaxy on a very pronounced ellipse, specifically eccentricity of 0.87. The apocenter (maximal distance from Earth) is about 57,000 ly ...

    en.wikipedia.org/wiki/Messier_object

    The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers. [1] The catalogue includes most of the astronomical deep-sky objects that can be easily observed from Earth's Northern Hemisphere; many Messier objects are popular targets for amateur ...

    Evil Eye Galaxy, M64, NGC 4826, PGC 44182, UGC 8062 [11] The Black Eye Galaxy (also called Sleeping Beauty Galaxy or Evil Eye Galaxy and designated Messier 64 , M64 , or NGC 4826 ) is a relatively isolated [ 7 ] spiral galaxy 17 million light-years away in the mildly northern constellation of Coma Berenices .

  5. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    The term 64-bit also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a word size that defines certain classes of computer architecture, buses, memory, and CPUs and, by extension, the software that runs on them. 64-bit CPUs have been used in supercomputers since the 1970s (Cray-1, 1975) and in reduced ...

  6. Crack tip opening displacement - Wikipedia

    en.wikipedia.org/wiki/Crack_tip_opening_displacement

    The specimen is placed on the work table and a notch is created exactly at the centre. The crack should be generated such that the defect length is about half the depth. The load applied on the specimen is generally a three-point bending load. A type of strain gauge called a crack-mouth clip gage is used to measure the crack opening. [3]

  7. Binary angular measurement - Wikipedia

    en.wikipedia.org/wiki/Binary_angular_measurement

    Signed binary angle measurement. Black is traditional degrees representation, green is a BAM as a decimal number and red is hexadecimal 32-bit BAM. In this figure the 32-bit binary integers are interpreted as signed binary fixed-point values with scaling factor 2 −31, representing fractions between −1.0 (inclusive) and +1.0 (exclusive).

  8. Category:Messier objects - Wikipedia

    en.wikipedia.org/wiki/Category:Messier_objects

    use [[Category:Messier objects|###]], dropping the M prefix, and using only the number. The number should be padded up to 3 digits using zeroes. Articles without the Messier number in the title use [[Category:Messier objects]]. A redirect containing the Messier number should also be added to the category, sorted as above.
