In excellent seeing conditions, it appears as large as the full moon. It shines bright at magnitude 4.0 and is easily visible with the unaided eye. The globular cluster 47 Tucanae also bears the catalog name NGC 104. Imagine the Toucan standing with its feet on the Small Magellanic Cloud. The bright ball of light to the upper right of the Small Magellanic Cloud is the globular cluster 47 Tucanae. | Can you spot Tucana the Toucan in this image of the night sky over the ALMA telescopes in Chile? The Small Magellanic Cloud lies within the border of Tucana. The result is this record-breaking image, the biggest infrared image of the Small Magellanic Cloud. The Visible and Infrared Survey Telescope allows a clearer view. Like the “cloud” in its name, the satellite galaxy also harbors obscuring dust clouds. The Small Magellanic Cloud galaxy is a striking feature of the southern sky, but visible-light telescopes cannot get a really clear view. Both of these nearby galaxies are being sucked inward by the Milky Way Galaxy and will eventually be absorbed by it. The Small Magellanic Cloud’s nearby kin, the Large Magellanic Cloud, lies in the constellations Mensa and Dorado. An excellent target for a telescope, clusters stream through its length and out one tail. The Small Magellanic Cloud has many clusters and nebulae within its expanse. It’s the smaller of the two satellite galaxies in the Southern Hemisphere skies, with the larger being the aptly named Large Magellanic Cloud. The Small Magellanic Cloud is an irregular galaxy but has a central bar as part of its structure, making it look like a disturbed former spiral.

You can see it without optical aid as a misty, cloudy patch from dark-sky locations. Small Magellanic Cloudĭespite its great distance of 200,000 light-years, the Small Magellanic Cloud is one of the closest galaxies to Earth. The nearby bright star is Achernar, across the border in the constellation Eridanus the River. The Small Magellanic Cloud is found in the southeast corner of the constellation Tucana. The whole Beta Tucanae system is an average of 140 light-years from Earth. Beta 2 shines at magnitude 4.53, and Beta 3 shines at 5.07. Beta 1 is the brightest and shines at magnitude 4.36. On the opposite side of the constellation from Alpha is Beta Tucanae, a star system containing six stars loosely bound together. The brightest star in Tucana is Alpha Tucanae, a magnitude 2.87 star that lies almost 200 light-years from Earth. Order yours before they’re gone! Stars of Tucana In fact, this constellation’s stars are harder to pick out than the globular cluster and galaxy that anchor its southern edge.

Plus southern stargazers know that a large globular star cluster – 47 Tucanae, visible to the unaided eye – is also located within the boundaries of Tucana. It’s because this constellation is famous for being home to the Small Magellanic Cloud, the fuzzy patch in the sky that represents one of two relatively large dwarf galaxies orbiting our Milky Way.
And, once we got there, we’d find that the stars of this constellation aren’t particularly bright or remarkable. So those of us in the Northern Hemisphere would have to travel southward on Earth’s globe to see Tucana. That’s because it’s near the south celestial pole, the point in the sky around which all southern stars revolve. The constellation Tucana the Toucan is visible year round from Earth’s Southern Hemisphere. Tucana the Toucan, deep in southern skies
It’s also home to another beautiful deep-sky object, visible to the unaided eye the globular star cluster 47 Tucanae. The claim to fame for Tucana the Toucan is that it’s in the same direction in the sky as where we see the Small Magellanic Cloud, a dwarf galaxy orbiting our Milky Way.
