Puppis appears to form the rear part of a great sailing ship with Carina and Vela forming the rest of the ship

Puppis Constellation Map

image

Légende : The constellation Puppis with its bright stars and surrounding constellations. Puppis is surrounded by (going clockwise from the top): Monoceros, Canis Major, Columba, Pictor, Carina, Vela, Pyxis and Hydra. Puppis 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 equatorial and some temperate regions of the northern hemisphere with parts of the constellation visible to all but the most arctic regions. Puppis is best viewed in the evenings in the northern hemisphere winter and southern hemisphere summer. The open clusters M46, M93 and NGC 2477 lie in Puppis and are marked here with yellow circles. The globular cluster M47 also lies in Puppis and is marked here with a yellow circle with a cross 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. Puppis was previously part of the larger Argo Navis constellation along with Vela and Carina. As the letter designations for stars were created before this division took place, Greek letter designations are now divided between the three constellations with Puppis having stars designated epsilon and zeta but no alpha, beta, gamma or delta. 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.

The stars in Tucana form an oval shape. The Small Magellanic Cloud lies in the constellation’s south east

Tucana Constellation Map

image

Légende : The constellation Tucana with its bright stars and surrounding constellations. Tucana is surrounded by (going clockwise from the top): Grus, Indus, Octans, Hydrus, Eridanus and Phoenix. Tucana 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 to some equatorial regions of the northern hemisphere with parts of the constellation visible to the remaining northern equatorial regions. Tucana is best viewed in the northern hemisphere autumn and southern hemisphere spring. The Small Magellanic Cloud (SMC), a satellite galaxy of the Milky Way lies in Tucana with a small part spilling over into the neighbouring constellation of Hydrus. The SMC is marked here with a green loop in the south east of Tucana. The globular clusters NGC 104, also known as 47 Tucanae or 47 Tuc, and NGC 362 lie in Tucana and are marked here with yellow circles with plus signs superimposed on them. While these two clusters appear close to the SMC on the sky, they are both significantly closer than that satellite galaxy. 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.

Vela appears to form the sail of a great sailing ship with Carina and Puppis forming the rest of the ship

Vela Constellation Map

image

Légende : The constellation Vela with its bright stars and surrounding constellations. Vela is surrounded by (going clockwise from the top): Pyxis, Puppis, Carina, Crux, Centaurus and Antlia. Vela 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 regions of the northern hemisphere with parts of the constellation visible from most temperate northern hemisphere regions. Vela is best viewed in the evening in the northern hemisphere spring and southern hemisphere autumn. The planetary nebula NGC 3132 lies in Vela and is marked here with a green circle superimposed on a plus sign. The globular cluster NGC 3201 also lies in Vela and is marked here with a yellow circle with a plus sign superimposed on it. A yellow circle marks the position of the open cluster IC 2391. 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.

Hydra is shaped like a snake going from the south east to the north west

Hydra Constellation Map

image

Légende : The constellation Hydra with its bright stars and surrounding constellations. Hydra is surrounded by (going clockwise from the top): Leo, Cancer, Canis Minor, Monoceros, Puppis, Pyxis, Antlia, Centaurus, Lupus, Libra, Virgo, Corvus, Crater and Sextans. Hydra is a large constellation that covers over a quarter of the celestial sphere in right ascension. It also spans the celestial equator and thus part of the constellation is visible from everywhere on the Earth at some point in the year. All parts of the constellation are visible at some point for all but the most antarctic parts of the southern hemisphere and to equatorial and most temperate regions of the northern hemisphere. However the wide span of the constellation means that all of it may not be visible at the same time in many of these regions. Hydra is best viewed in the northern hemisphere spring and southern hemisphere autumn. The famous spiral galaxy M83, also known as the Pinwheel Galaxy, lies in Hydra. It is marked here with a red ellipse. The planetary nebula NGC 3242 can also be found in Hydra. It is marked here with a green circle with a plus sign superimposed on it. The open cluster M48 is marked here with a yellow circle while the globular cluster M68 is marked with a yellow circle with a plus sign 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. The blue line on 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.
