Lacerta Constellation Map

imagem

Legenda: The constellation Lacerta with its bright stars and surrounding constellations. Lacerta is surrounded by (going clockwise from the top): Cepheus, Cygnus, Pegasus, Andromeda and Cassiopeia. Lacerta 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 regions of the southern hemisphere with parts of the constellation visible from temperate southern regions. The whole constellation is circumpolar from arctic regions. Lacerta is best viewed in the evenings in the northern hemisphere autumn and southern hemisphere spring. The open cluster NGC 7243 lies in Lacerta, it is marked here with a yellow circle. 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.

Mapa da Constelação de Cão Maior

imagem

Legenda: A constelação de Cão Maior com suas estrelas brilhantes e as constelações vizinhas. Cão Maior é cercada por (no sentido horário a partir do topo): Unicórnio, Lebre, Pomba e Popa. A constelação é dominada por Sirius, a estrela que aparece mais brilhante no céu noturno, que supera em muito todas as outras estrelas da constelação. Cão Maior fica ao sul do equador celeste e é visível de todo o hemisfério sul, bem como das regiões equatoriais e temperadas do hemisfério norte. Sirius é visível de todas as regiões, com exceção das mais árticas. Cão Maior é mais visível à noite, no final do inverno no hemisfério norte e no final do verão no hemisfério sul. Os aglomerados estelares abertos M41, NGC 2360 e NGC 2362 estão na constelação. Eles estão marcados com círculos amarelos. O eixo y desse diagrama está em graus de declinação, com o norte para cima, e o eixo x está em horas de ascensão reta, com o leste à esquerda. Os tamanhos das estrelas marcadas aqui estão relacionados à magnitude aparente da estrela, uma medida de seu brilho aparente. Os pontos maiores representam estrelas mais brilhantes. As letras gregas marcam as estrelas mais brilhantes da constelação. Elas são classificadas por brilho, com a estrela mais brilhante sendo rotulada como alfa, a segunda mais brilhante como beta etc., embora essa ordem nem sempre seja seguida exatamente. As linhas de divisão pontilhadas marcam os limites das constelações da IAU e as linhas verdes sólidas marcam uma das formas comuns usadas para representar as figuras das constelações. Nem os limites da constelação nem as linhas que unem as estrelas aparecem no céu.

Cancer Constellation Map

imagem

Legenda: The zodiac constellation Cancer and its surrounding constellations. Starting from the top of the diagram and going clockwise, these are Lynx, Gemini, Canis Minor, Hydra, Leo and Leo Minor. The ecliptic (shown here as a blue line) passes almost exactly through the middle of the constellation, this is the path the Sun appears to take across the sky over the course of a year. The Sun is in Cancer from late July to mid August. The other planets of the Solar System can often be found in Cancer. Cancer lies just north of the celestial equator and is thus visible at some time in the year from all of planet Earth except for the most antarctic regions of the world. Cancer is most visible in the evenings in the northern hemisphere spring and southern hemisphere autumn. Two star clusters are visible in Cancer: M44, an open cluster often called the Beehive Cluster, and M67, a denser open cluster with about four times more stars than M44. These clusters are indicated by yellow circles with a dotted border on the map. 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 labelled 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 line marking the ecliptic, nor the lines joining the stars appear on the sky.

Carina Constellation Map

imagem

Legenda: The constellation Carina along with its bright stars and surrounding constellations. Carina is surrounded by (going clockwise from the top): Vela, Puppis, Pictor, Volans, Chamaeleon, Musca and Centaurus. Carina is notable for Canopus, the second brightest star in the night sky and for the famous variable star Eta Carinae. This latter object is a binary star system of two young very massive stars. Its brightness has varied greatly over the past few centuries. At one point it outshone Canopus before dimming by a factor of four thousand to become invisible to the naked eye. In recent years it has brightened enough to again be visible without the aid of a telescope. Carina is a southern constellation and thus the whole constellation is visible at some point in the year to the entire southern hemisphere. The whole constellation is also visible from equatorial regions of the northern hemisphere with parts of the constellation visible from northern temperate regions. The open clusters NGC 2516, NGC 3532 and IC 2602 lie in Carina. These are marked here by yellow circles. The Carina Nebula, also known as NGC 3372, lies in the constellation. This large nebula contains many massive young stars, including Eta Carinae. This diagram maps an area around the south celestial pole. Here lines of constant right ascension converge. The right ascension values of these lines are marked on the x-axis above and below the diagram. Some of the lines of constant declination are marked on the y-axis. 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. Carina was previously part of the larger Argo Navis constellation along with Vela and Puppis. As the letter designations for stars were created before this division took place, Greek letter designations are now divided between the three constellations with Carina having stars designated alpha and beta but no 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.

Serpens Cauda Constellation Map

imagem

Legenda: A map of part of the constellation Serpens. Serpens is unique amongst IAU constellations in that it is divided into two non-contiguous parts. The part of Serpens shown here is known as Serpens Cauda, representing the tail of the serpent. This part of Serpens is surrounded by (going clockwise from the top): Ophiuchus, Sagittarius, Scutum and Aquila. Serpens Cauda spans the celestial equator thus parts of the constellation are visible at some point in the year across the Earth. The whole constellation is visible to all but the most arctic and antarctic regions. Serpens Cauda is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The Eagle Nebula and its associated star cluster are marked here as M16 with a yellow circle. This region was the location of the famous “pillars of creation” image taken by the Hubble Space Telescope. 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.
