	Image of the Day : Starry Toucan
		The southern constellation Tucana (the Toucan) is home to several clutches of stars, among them the globular cluster 47 Tucanae.
		Seen here, 47 Tucanae is one of the largest and brightest globular clusters in the night sky, and is surpassed only by an object known as Omega Centauri.
		Globular clusters contain several tens of thousands of stars which are all thought to have formed from the same cloud of gas at about the same time.

		Tucana, or the toucan (Tuc) is a small austral constellation located in the parallel of 60º of South, observable latitude solely in the South hemisphere during great part of the year and not in the north where I write these lines to you.
		Tucana limits the north with the constellations of Phoenix and Grux, to the east with Indus, the south with Octans and Hidrus and to the west with this one last one.

	Alpha Tucanae (Site not responding. Last check: 2007-10-28)
		Tucana, the latter more or less the counterpart of the celestial Queen, but being a toucan, much less regal.
		Tucana is known for the "Small Magellanic Cloud," a small nearby galaxy that lies only 200,000 light years away, and for the magnificent globular cluster 47 Tuc, both of which far overshadow the constellation's luminary, third magnitude (2.86) Alpha Tucanae.
		Only 30 degrees from the South Celestial Pole, Alpha Tucanae is circumpolar from much of the southern hemisphere, for all those to the south of 30 or so degrees south latitude, but never rises for anyone north of 30 degrees north.

		The Southern constellation Tucana (the Toucan) is probably best known as the home of the Small Magellanic Cloud, one of the satellite galaxies of the Milky Way.
		But Tucana also hosts another famous object that shines thousands of lights, like a magnificent, oversized diamond in the sky: the globular cluster 47 Tucanae.
		47 Tucanae is an impressive globular cluster that is visible with the unaided eye from the southern hemisphere.

		The bold and innovative observation pushed NASA Hubble Space Telescopeís capabilities to its limits, simultaneously scanning for small changes in the light from 35,000 stars in the globular star cluster 47 Tucanae, located 15,000 light-years (4 kiloparsecs) away in the southern constellation Tucana.
		The ideal target was the magnificent southern globular star cluster 47 Tucanae, one of the closest clusters to Earth.
		47 Tucanae is old and so is deficient in the heavier elements, which were formed later in the universe through the nucleosynthesis of heavier elements in the cores of first-generation stars.

	Hubble finds infant stars in neighbouring galaxy
		Hubble astronomers have uncovered, for the first time, a population of infant stars in the Milky Way satellite galaxy, the Small Magellanic Cloud (SMC, visible to the naked eye in the southern constellation Tucana), located 210,000 light-years away.
		The exquisite sharpness of the NASA/ESA Hubble Space Telescope has plucked out an underlying population of infant stars embedded in the nebula NGC 346 that are still forming from gravitationally collapsing gas clouds.
		The image was composed from two individual exposures taken through a V filter (555 nm, shown in blue) and a near-infrared filter (814 nm, shown in red).

	47 Tucanae (NGC 104)
		Binoculars clearly show an increase in brightness toward the center and a telescope with an aperture of at least 10 cm resolves some of the roughly 100,00 member stars.
		Although a conspicuous naked-eye sight, it lies so far south, in the constellation Tucana, that it wasn't discovered by astronomers until 1751 when Nicholas de Lacaille catalogued it in his list of southern nebulous objects.
		A search for Jupiter-like planets in 47 Tuc, carried out by an international team of astronomers using data from the Hubble Space Telescope, came up empty-handed.

	Epsilon Indi
		This star system is located about 11.8 light-years (ly) away from our Sun, Sol, at the northwestern edge (22:03:21.66-56:47:09.51, ICRS 2000.0) of Constellation Indus, the Indian -- southeast of Delta Indi and northwest of Alpha Tucanae.
		Epsilon Indi has such a high proper motion that, within a few thousand years, it will have moved out of Constellation Indus constellation and into neighboring Constellation Tucana, the Toucan.
		Constellation Indus was created by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman, who charted the southern skies from 1595 to 1597.

		The story behind the name: Tucana is named for the Toucan, a brightly colored South American bird with a very large, thick bill.
		Tucana is another collaboration between the Dutch navigators Keyser and de Houtman who charted the southern skies on a voyage to the East Indies, and Johann Bayer, an astronomer who cataloged and published their newly discovered star patterns in his 1603 sky atlas.
		Other astronomers, such as Johannes Kepler, who formulated the three laws of planetary motion, and Giovanni B. Riccioli, who was the first to observe a double star, called it Anser Americanus, the American Goose.

	Hubble opens southern window on distant galaxies
		Training its most far-sighted instruments to a point near the constellation Tucana, the Hubble spied thousands of galaxies ranged along a corridor in deep space some 12 billion light-years long.
		These latest observations were made over a 10-day period in October, and complement a similar Hubble survey of ancient galaxies made in 1995, when the orbiting telescope looked at a patch of northern sky near the Big Dipper constellation.
		The 1995 survey brought thousands of distant, faint galaxies -- some of them dating back 12 billion years or more -- to astronomers' attention, and the latest survey, known as Hubble Deep Field South, is expected to prompt research into a new region of the cosmos.

	Constellation Tucana (Site not responding. Last check: 2007-10-28)
		A small constellation in the cirumpolar region of the south pole of the sky.
		There are only few bright stars in this region, but Tucana became known due to the presence of the Small Magellanic Cloud and the second brightest globular cluster in the sky, 47 Tucanae, NGC 104.
		In fact it is a sextuple, but the other components are too faint to be observed with small scopes.

	Science: Galaxy becomes new member of our Local Group - 26 October 1991 - New Scientist
		Two astronomers in Australia have discovered that a faint galaxy in the southern constellation Tucana is a member of the Local Group of galaxies.
		The Tucana galaxy lies on the opposite side of the Milky Way to most members of the Local Group, so it may provide unique insight into the nature and origin of this collection of galaxies.
		Astronomers in the US first catalogued the Tucana galaxy in the 1980s, but they did not realise how close it was.
