Crater Constellation Map

صورة

الشرح: The constellation Crater with its bright stars and surrounding constellations. Crater is surrounded by (going clockwise from the top): Leo, Sextans, Hydra, Corvus and Virgo. Crater is a southern constellation so the whole of the cluster is visible at some point in the year from the whole of the southern hemisphere.The whole constellation is also visible from temperate and equatorial regions of the northern hemisphere. The constellation is best viewed in the evening in the northern hemisphere spring and southern hemisphere autumn. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line at the top left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.

Scorpius Constellation Map

صورة

الشرح: The constellation Scorpius (often commonly called Scorpio) along with its bright stars and surrounding constellations. Scorpius is surrounded by (going clockwise from the top) Ophiuchus, Serpens Caput, Libra, Lupus, Norma, Ara, Corona Australis and Sagittarius. Scorpius’s brightest star Antares appears in the heart of the constellation with the famous tail of Scoprius in the south-east (lower left). Scorpius lies on the ecliptic (shown here as a blue line), this is the path the Sun appears to take across the sky over the course of a year. The Sun only spends a short amount of time in late November in Scorpius. The other planets of the Solar System can often be found in Scorpius. Scorpius lies south of the celestial equator. The whole constellation is not visible from the most arctic regions of the world with parts of Scorpius obscured for observers in northern parts of Asia, Europe and North America. Scorpius is most visible in the evenings in the northern hemisphere summer and southern hemisphere winter. The yellow circles mark the positions of the open clusters M6, M7 & NGC 6231 while the yellow circles with plus signs superimposed on them mark the globular clusters M4 and M80. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The circle around Antares indicates that it is a variable star. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line marks the ecliptic, the path the Sun appears to travel across the sky over the course of one year. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.

Lupus Constellation Map

صورة

الشرح: The constellation Lupus with its bright stars and surrounding constellations. Lupus is surrounded by (going clockwise from the top): Libra, Hydra, Centaurus, Circinus, Norma and Scorpius. Lupus is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is visible in equatorial and some temperate regions of the northern hemisphere with parts of the constellation visible to remaining temperate regions. Lupus is best viewed in the evenings in the northern hemisphere summer and southern hemisphere winter. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars.

Piscis Austrinus Constellation Map

الشرح: The constellation Piscis Austrinus with its bright stars and surrounding constellations. Piscis Austrinus is surrounded by (going clockwise from the top): Aquarius, Capricornus, Microscopium, Grus and Sculptor. Piscis Austrinus is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible to some equatorial regions of the northern hemisphere with parts of the constellation visible to the remaining equatorial and some temperate northern hemisphere regions. Piscis Austrinus is best viewed in the evening in the northern hemisphere autumn and southern hemisphere spring. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left.

The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line in the top right of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

Scutum Constellation Map

صورة

الشرح: The constellation Scutum with its brighter stars and surrounding constellations. Scutum is surrounded by (going clockwise from the top): Serpens Cauda, Sagittarius and Aquila. Scutum is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible from equatorial and temperate regions of the northern hemisphere with parts of the constellation visible from all but the most arctic regions. Two open clusters lie in Scutum: M11, commonly known as the Wild Duck Cluster; and M26. Both of these are marked here with yellow circles. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line at the bottom of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.
