is the combined magnitude of the coma and nucleus. The apparent magnitude of an astronomical object is generally given as an integrated value—if a galaxy...

Apparent magnitude (m) is a measure of the brightness of a star, astronomical object or other celestial objects like artificial satellites. Its value...

pink hue, common to emission nebulae. It is fairly bright, with an integrated magnitude of 3.0. The Lagoon Nebula was discovered independently by John Flamsteed...

only viewable as a very faint object, though it has a fairly high integrated magnitude of 6.0. One of the visible galaxies in Aquarius is NGC 7727, of particular...

Orion is NGC 1999, also close to the Great Orion Nebula. It has an integrated magnitude of 10.5 and is 1500 light-years from Earth. The variable star V380...

dozen members but is best observed with binoculars. It has a total integrated magnitude (brightness) of 4.6 and spans an angular diameter of 29 arcminutes...

known, with an estimated age of 14 million years. It has a total integrated magnitude of 4.2, is located 1.95 kpc. or 6,440 light years from Earth, and...

Its old astronomical symbol is (♎︎). It is fairly faint, with no first magnitude stars, and lies between Virgo to the west and Scorpius to the east. Beta...

in England at the time. It has an integrated magnitude of 8.0 and is approximately 0.25° long. NGC 1502 is a magnitude 6.9 open cluster about 3,000 light...

convention is used. A galaxy's magnitude is defined by measuring all the light radiated over the entire object, treating that integrated brightness as the brightness...

second magnitude), Sheratan (Beta Arietis, third magnitude), Mesarthim (Gamma Arietis, fourth magnitude), and 41 Arietis (also fourth magnitude). The few...

extending the binary numeral system to represent signed numbers are: sign–magnitude, ones' complement, two's complement, and offset binary. Some of the alternative...

star formation and have strong ultraviolet emissions. It has an integrated magnitude of 7.5, making it visible in both binoculars and telescopes, but...

difficult target for an amateur telescope. NGC 1931 has an approximate integrated magnitude of 10.1; it is 3 by 3 arcminutes. However, it appears to be elongated...

best known planetary nebulae and the second to be discovered; its integrated magnitude is 8.8. It was discovered in 1779 by Antoine Darquier, 15 years after...

Gamma1 Normae. Its integrated magnitude is 13.6 and its mean surface brightness is 13.9. The central star is a white dwarf of magnitude 14.03. Mz 1 is a...

to be intertwined. Even though the nebula has a relatively bright integrated magnitude of 7, it is spread over so large an area that the surface brightness...

enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed...

spiral galaxy with an integrated magnitude of 9.0. M94 (NGC 4736) is a small face-on spiral galaxy with approximate magnitude 8.0, about 15 million light-years...

Comparatively, open cluster NGC 5715 is fainter (integrated magnitude of 9.8)—its brightest star is only 11th magnitude—and smaller (7.0 arcminutes), comprising...
