Canes Venatici Constellation Map

صورة

الشرح: The constellation Canes Venatici with its brighter stars and surrounding constellations. Canes Venatici is surrounded by (going clockwise from the top): Ursa Major, Coma Berenices and Boötes. Canes Venatici is a northern constellation and thus the whole constellation is visible at some point in the year from the whole of the northern hemisphere. The whole of the constellation is also visible from equatorial regions of the southern hemisphere with parts of it visible from temperate southern regions. The constellation is best viewed in the northern hemisphere late spring and southern hemisphere late autumn. The famous spiral galaxy commonly known as the Whirlpool Galaxy (M51) lies in Canes Venatici and is marked here with a red ellipse. Other notable spiral galaxies in the constellation include M63, M94, M106 and NGC 4631. All are marked here with red ellipses. The globular cluster M3 is marked here with a yellow circle with a plus symbol superimposed on it. 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. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.

Triangulum Constellation Map

صورة

الشرح: The constellation Triangulum with its bright stars and surrounding constellations. Triangulum is surrounded by (going clockwise from the top): Andromeda, Pisces, Aries and Perseus. Triangulum is a northern constellation and thus the whole constellation is visible at some point in the year throughout the northern hemisphere. The whole constellation is also visible from equatorial and most temperate regions of the southern hemisphere. Triangulum is best viewed in the evening in the northern hemisphere winter and southern hemisphere summer. The Triangulum Galaxy M33 lies in the constellation. This spiral galaxy is the third largest member of the local group of galaxies after the Andromeda Galaxy and Milky Way. It is marked here with a red ellipse. 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 left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

Fornax Constellation Map

صورة

الشرح: The constellation Fornax with its bright stars and surrounding constellations. Fornax is surrounded by (going clockwise from the top): Cetus, Sculptor, Phoenix and Eridanus. Fornax is a southern constellation and thus the whole constellation is visible in the whole southern hemisphere at some point in the year. The whole constellation is also visible from equatorial and most temperate regions of the northern hemisphere. Fornax is best viewed in the northern hemisphere winter and southern hemisphere summer. The spiral galaxy NGC 1097 lies in Fornax and is marked here with a red ellipse. 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.

Ursa Major Constellation Map

صورة

الشرح: The constellation Ursa Major along with its bright stars and its surrounding constellations. Ursa Major is surrounded by (going clockwise from the top): Draco, Camelopardalis, Lynx, Leo Minor, Leo, Coma Berenices, Canes Venatici and Boötes. Ursa Major is famous for the prominent asterism often known in English as the Big Dipper or the Plough. This prominent northern asterism has a wide variety of names from cultures across the world. While most constellations and asterisms are made up of unrelated stars that randomly appear close together on the sky, five of the stars in the Big Dipper are part of the Ursa Major Moving Group, a group of stars moving through space together that likely formed in the same location 300 million years ago. The two stars on the right-hand end of the Big Dipper on this diagram form a pair of pointer stars that can be used to locate Polaris, the northern pole star which lies in the constellation of Ursa Minor. Ursa Major is a northern constellation and is visible from northern and equatorial regions. Parts of the constellation are visible from all but the most antarctic parts of the southern hemisphere but not all temperate regions of the southern hemisphere can see all of the Big Dipper. Conversely the Big Dipper and much of the rest of the constellation are circumpolar in arctic and many temperate regions of the northern hemisphere. Ursa Major is most visible in the evening in the northern hemisphere spring and southern hemisphere autumn. Two prominent galaxies appear in the northern part of this constellation, the spiral galaxy M81 and M82, a possible spiral galaxy whose structure is difficult to observe from the Earth as it appears edge-on. Both are shown here as red ellipses. The planetary nebula M97 (the Owl Nebula) lies in the middle of the constellation and is marked by a green circle superimposed on a plus symbol. 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. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.

Sculptor Constellation Map

صورة

الشرح: The constellation Sculptor with its brighter stars and surrounding constellations. Sculptor is surrounded by (going clockwise from the top): Cetus, Aquarius, Piscis Austrinus, Grus, Phoenix and Fornax. Sculptor 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 in equatorial and most temperate regions of the northern hemisphere. Parts of the constellation are also visible to the remaining northern temperate regions. Sculptor is best viewed in the evening in the late northern hemisphere autumn and late southern hemisphere spring. The irregular galaxy NGC 55, and the spiral galaxies NGC 253 and NGC 300 all lie in Sculptor. There are marked here with red ellipses. 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.
