Interference filters were used to restrict the wavelength range and, hence, decrease the background and crowding. The limiting absolute magnitude of the survey is about   The tip of the "wing" of the Small Magellanic Cloud galaxy is dazzling in this new view from NASA's Great Observatories. The Small Magellanic Cloud, or SMC, is a small galaxy about , light-years way that orbits our own Milky Way spiral galaxy. The .   Astronomers have combined hundreds of thousands of Spitzer Space Telescope images into a map of the whole Large Magellanic Cloud. They see features throughout the galaxy in such sharp detail that they can count newly formed stars, determine how much dust old stars are pumping into the galaxy and, for the first time, sensitively map the rate at which stars are forming across an entire galaxy.

The following image of the Large Magellanic Cloud (LMC) was taken with a Canon D and a Canon EFS 60mm f/ lens at ISO on the tracker, using autoguiding.

Combined, the peak contribution from these cool evolved stars occurs at ∼3–4μm, where they produce 32% of the SMC light, and 25% of the LMC flux. The TP-AGB star contribution also peaks at ∼3–4μm.

The Large Magellanic Cloud (LMC) is a satellite galaxy of the Milky Way. At a distance of about 50 kiloparsecs (≈, light-years), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (~16 kpc) and the possible dwarf irregular galaxy known as the Canis Major on readily visible stars and a mass of approximately 10 Apparent size (V): ° × °.

The Small Magellanic Cloud (SMC), or Nubecula Minor, is a dwarf galaxy near the Milky Way. Classified as a dwarf irregular galaxy, the SMC has a diameter of about 7, light-years, contains several hundred million stars, and has a total mass of approximately 7 billion solar masses.

The SMC contains a central bar structure, and astronomers speculate that it was once a barred spiral galaxy that Constellation: Tucana and Hydrus. The first book published by the press contained the proceedings of a one day meeting of the Astronomical Society of New York, held at Colgate University on the subject, "X-Ray Symposium ".

In the Milky Way, hundreds of discrete objects of differ-ent classes have been detected, together with diffuse interstellar emission over a broad range of spatial scales.

Like many other irregular galaxies, the LMC contains large volumes of dust and gas, and stars are currently being formed at a high rate all over the galaxy. In fact, despite its diminutive size, the LMC contains the Tarantula Nebula, which is one of the largest, and most active star-forming regions in the entire Local Group of Galaxies.

The HII regions in the Large Magellanic Cloud (LMC) offer ideal sites to study the stellar energy feedback effects on dust because stars can be resolved, and the galaxy's nearly face-on.

The Large Magellanic Cloud (LMC) is ablaze with star-forming regions. From the Tarantula Nebula, the brightest stellar nursery in our cosmic neighborhood, to LHA N 11, part of which is featured in this Hubble image, the small and irregular galaxy is scattered with glowing nebulae, the most noticeable sign that new stars are being born.

From previous samples of Red Supergiants (RSGs) by various groups, objects are assembled to compose a large sample of RSG candidates in LMC.

For of them, the identity as a RSG is verified by their brightness and color indexes in several near- and mid-infrared bands related to the 2MASS JHKs bands and the Spitzer/IRAC and Spitzer/MIPS bands.

This newly released Hubble image shows the globular cluster NGCa gathering of white and blue stars in the southern constellation of Dorado (The Dolphinfish). NGC is located aboutlight-years away, in the Large Magellanic Cloud (LMC), one of our closest cosmic neighbors and a satellite galaxy of the Milky Way.

Large Magellanic Cloud (LMC) Large Magellanic Cloud (LMC) is an irregular galaxy spanning the constellations Dorado and Mensa. It has an apparent visual magnitude of and its angular diameter is x arc-minutes. LMC lies at an estimated distance oflight years. LHA N55, or N55 as it is usually known, is a glowing gas cloud in the Large Magellanic Cloud, a satellite galaxy of the Milky Way located aboutlight-years away.

N55 is situated inside a supergiant shell, or superbubble called LMC 4. The Magellanic Clouds are irregular galaxies that share a gaseous envelope and lie about 22° apart in the sky near the south celestial pole. One of them, the Large Magellanic Cloud (LMC), is a luminous patch about 5° in diameter, and the other, the Small Magellanic Cloud (SMC), measures less than 2° across.

The Magellanic Clouds are visible to the unaided eye in the Southern Hemisphere, but. The Large Magellanic Cloud: Structure and Kinematics By Roeland P. van der Marel Space Telescope Science Institute, San Martin Drive, Baltimore, MD I review our understanding of the structure and kinematics of the Large Magellanic Cloud (LMC), with a particular focus on recent results.

This is an important topic, given the status. The Large Magellanic Cloud lies only aboutlight-years distant towards the constellation of Dorado. Spanning ab light-years, the LMC was the site of SNA, the brightest and closest supernova in modern times.

Together with the Small Magellanic Cloud (SMC), the LMC can be seen in Earth's southern hemisphere with the unaided eye. The first preserved mention of the Large Magellanic Cloud was by Persian astronomer Al Sufi, who in A.D., in his Book of Fixed Stars calls it Al Bakr, the White Ox, of the southern Arabs, and points out that while invisible from Northern Arabia and Baghdad, this object is visible from the Strait of Babd al Mandab, at 12deg 15' Northern.
