[14], Using this period-luminosity relation, in 1913 the distance to the SMC was first estimated by Ejnar Hertzsprung. This image is not blurry. hide. [32] The third Ariel 5 catalog (3A) also contains this early X-ray source within Tucana: 3A 0116-736 (2A 0116-737, SMC X-1). About 210,000 light-years away in the constellation of the Tucan ( Tucana ), it is more distant than other known Milky Way satellite galaxies , including the Sagittarius Dwarf galaxy and the Large Magellanic Cloud . [15] This later proved to be a gross underestimate of the true distance, but it did demonstrate the potential usefulness of this technique. [19], In 2017, using Dark Energy Survey plus MagLiteS data, a stellar over-density associated with the Small Magellanic Cloud was discovered, which is probably the result of interactions between SMC and LMC.

What is the Small Magellanic Cloud? They suggest the reason for this is due to a past interaction with the LMC splitting the SMC, and that the two sections are still moving apart. People who have wondered about this little fuzzy patch in the southern sky included Portuguese navigator Ferdinand Magellan and his crew, who had plenty of time to study the unfamiliar night sky of the south during the first circumnavigation of planet Earth in the early 1500s. The SMC has an average apparent diameter of about 4.2° (8 times the Moon's) and thus covers an area of about 14 square degrees (70 times the Moon's).

Within the area of this cloud he catalogued a concentration of 37 nebulae and clusters. They have dubbed this smaller remnant the Mini Magellanic Cloud. First determined with Hubble, the rotation of the LMC is presented here with fine data from the Sun-orbiting Gaia satellite. [21] The Be-star equatorial disk provides a reservoir of matter that can be accreted onto the neutron star during periastron passage (most known systems have large orbital eccentricity) or during large-scale disk ejection episodes. Required fields are marked *. [12] Henrietta Swan Leavitt, an astronomer at the Harvard College Observatory, used the plates from Arequipa to study the variations in relative luminosity of stars in the SMC.

They may be the objects mentioned by the polymath Ibn Qutaybah (d. 889 CE), in his book on Al-Anwā̵’ (stations of the Moon in pre-Islamic Arabian culture): Recent studies using XMM-Newton[25] and Chandra[26] have now cataloged several hundred X-ray sources in the direction of the SMC, of which perhaps half are considered likely HMXBs, and the remainder a mix of foreground stars, and background AGN. The Small Magellanic Cloud (More commonly called the SMC, or, by natives, Ventemir) is one of the largest satellites of the Milky Way galaxy, ranking at the number five largest satellite galaxy of the Milky Way. The ROSAT and ASCA missions detected many faint X-ray point sources,[24] but the typical positional uncertainties frequently made positive identification difficult.

Like its larger apparent neighbor, the Large Magellanic Cloud, the Small Magellanic Cloud was certainly known to the ancient southerners, and was probably mentioned by Amerigo Vespucci in a letter written during his third voyage about 1503-4, but became known to us only when Magellan went on his journey around the world, in 1519. People who have wondered about this little fuzzy patch in the southern sky included Portuguese navigator Ferdinand Magellan and his crew, who had plenty of time to study the unfamiliar night sky of the south during the first circumnavigation of planet Earth in the early 1500s. [33], It has been proposed by astrophysicists D. S. Mathewson, V. L. Ford and N. Visvanathan that the SMC may in fact be split in two, with a smaller section of this galaxy behind the main part of the SMC (as seen from Earth perspective), and separated by about 30,000 ly. The Small Magellanic Cloud (SMC), or Nubecula Minor, is a dwarf galaxy near the Milky Way. The Small Magellanic Cloud (SMC), pictured here , is about 250,000 light years away and contains a preponderance of young, hot, blue stars indicating it has undergone a recent period of star formation.
