Knowledge King - Local Group M33, the third largest galaxy in the Local Group may or may not be a companion to the Andromeda galaxy but probably has LGS 3 as a satellite. These two spirals each have a system of satellite galaxies. The group is comprised of over 30 galaxies; its gravitational center is located somewhere between the Milky Way and the Andromeda Galaxy. www.knowledgeking.net /encyclopedia/l/lo/local_group.html

Irregular Galaxies Other examples of irregular galaxies are the Large Magellanic Cloud (a satellite galaxy of the Milky Way) and the Messier object M82. This irregular galaxy is a member of the Local Group, at a distance of about 10 million light years (Ref). Hubble's original classification just lumped all galaxies that are not spirals or elliptical into the irregular category, but it is more common today to make further distinction between more "normal" irregular galaxies and peculiar galaxies, which are galaxies that look unusual in some respect (M82, for instance). csep10.phys.utk.edu /astr162/lect/galaxies/irregular.html   (246 words)

Multiwavelength Small Magellanic Cloud - Irregular Galaxy The image was taken with a small infrared telescope aboard the Midcourse Space Experiment (MSX), a military satellite that orbited the Earth in 1996-1997. Both of these galaxies are named in honor of the explorer Ferdinand Magellan, who noted their presence in becoming the first to sail around the world nearly 500 years ago. While considered dwarf galaxies, their close proximity means that the Magellanic Clouds subtend a large angle on the sky. coolcosmos.ipac.caltech.edu /cosmic_classroom/multiwavelength_astronomy/multiwavelength_museum/smc.html   (908 words)

Sagittarius Dwarf Irregular Galaxy - Wikipedia, the free encyclopedia SagDIG should not be confused with the Sagittarius Dwarf Elliptical Galaxy or SagDEG, a satellite galaxy of the Milky Way. The Sagittarius Dwarf Irregular Galaxy or SagDIG is a dwarf galaxy in the constellation of Sagittarius.

Satellite photographs reveal ancient road system CORONA satellite imagery permits archaeologists to measure the size of ancient sites with great precision because it enables measurement of uneven, irregular walls such as the site of ancient Nineveh in Iraq, across the Tigris river from modern day Mosul. The ancient roads, which are clearly seen in CORONA satellite surveillance photographs, indicate that the settlement was an important city. Archaeologists at the University of Chicago’s Oriental Institute have used recently declassified satellite surveillance images to show that subtle land depressions–which had gone largely unnoticed by scholars–are actually the remnants of ancient roadways that knitted together the fabric of emerging civilizations in the ancient Near East. www-news.uchicago.edu /releases/03/030128.ancientroads.shtml   (704 words)

Media - Satellite Television - Worldpress.org Irregular or nonexistent electricity supplies are a common feature of the sub-Saharan landscape, which is an obvious barrier to the growth of television. One field of assured success for cable and satellite stations operating in the South is the children’s market, which was neglected by national channels. Western influence on television should not be underestimated, but it is not as saturating as the proponents of cultural imperialism believe—and while there may be many American soaps filling in the dead times in the afternoon, they are not, in general, the most popular programs. www.worldpress.org /Europe/947.cfm   (3368 words)

Irregular galaxy - Hutchinson encyclopedia article about Irregular galaxy The two satellite galaxies of the Milky Way, the Magellanic Clouds, are both irregulars. Some galaxies previously classified as irregulars are now known to be normal galaxies distorted by tidal effects or undergoing bursts of star formation (see starburst galaxy).

Assorted natural satellite pseudo-MPECs The data for irregular satellites was mostly gleaned from Minor Planet Center data.

Sculptor Dwarf Galaxy - Wikipedia, the free encyclopedia The Sculptor Dwarf Galaxy (also called E351-G30, PGC 3589, A0058, Sculptor Dwarf Spheroidal Galaxy) is a dwarf spheroidal galaxy in the Local Group that is a satellite of the Milky Way in the direction of the constellation of Sculptor.

MIMIC A tropical cyclone is passed over by one of these satellites only every 4-5 hours on average, although the time gaps are irregular, ranging from 30 minutes to as much as 25 hours. This allows the visual effect of rapidly-emerging or advecting cells inside larger areas of convection, which is observed in surface radar rapid scan imagery but is not apparent at the original temporal resolution of the satellite microwave imagery. The signal from these channels is strongly attenuated from hydrometeors generated by deep convection, and therefore the imagery is often used as a proxy for the distribution of precipitation. cimss.ssec.wisc.edu /tropic/real-time/marti/description.html   (740 words)

The Local Group The other members, mostly dwarf irregulars, cannot be assigned to one of these main subgroups, and float quite alone in the gravitational field of the giant group members. The third-largest galaxy, the Triangulum spiral M33, may or may not be an outlying gravitationally bound companion of M31, but has itself probably the dwarf LGS 3 as a satellite. The next more distant galaxy groups, the NGC 4244 group and the CVn I Cloud (with M94 and M64) are probably too remote to have interacted significantly with the Local Group in the past. www.seds.org /messier/more/local.html   (1626 words)

Local Group - Wikipedia, the free encyclopedia These two spirals each have a system of satellite galaxies. The Local Group is the group of galaxies that includes our galaxy, the Milky Way.

Our Milky Way Galaxy and its companions Both Magellanic Clouds are irregular dwarf galaxies orbiting our Milky Way galaxy, and thus are members of our Local Group of galaxies. Our current distance value takes into account the corrected Cepheid distance scale based on the Hipparcos satellite data published in early 1997. This dwarf galaxy remained undiscovered -- despite its enormous extent on the sky of 5 x 10 degrees -- because it can only be detected as a slight enhancement of the density of stars on the sky; the actual surface brightness of this galaxy is very low. www.public.asu.edu /~rjansen/localgroup/localgroup.html   (1626 words)

Sagittarius Dwarf Elliptical Galaxy (SagDEG, Sag dSph) A satellite galaxy of the Milky Way and the closest external galaxy; it is populated, as usual for a dwarf elliptical galaxy, by old yellowish stars. SagDEG should not be confused with another member of the Local Group, also in the constellation Sagittarius - the Sagittarius Dwarf Irregular Galaxy (SagDIG). SagDEG orbits our galaxy in less than one billion years and must therefore have passed through the dense central region of the Milky Way at least 10 times during our galaxy’s lifetime. www.daviddarling.info /encyclopedia/S/SagDEG.html   (1626 words)

satellite.html The lack of irregular satellites near inclinations of 90 degrees is believed to be due to the effect of the Kozai resonance, but may also occur due to the mechanism involved in the satellites' origin. The lack of irregular satellites at Neptune (other than Nereid), if observationally confirmed, may have resulted from the gravitational effect of its massive satellite Triton, which is believed to have been captured onto an initially eccentric orbit and may have ejected many pre-existing irregular satellites before tides circularized its orbit. The clumping of bodies at several different locations in this diagram suggests a few groups of irregular satellites with similar orbits, each of which may have originated by the disruption of one parent body. www.boulder.swri.edu /~davidn/satellite/satellite.html   (445 words)

Cornell News: New moons of Saturn discovered Burns notes that an irregular satellite's orbit is "long and looping," unlike the orbit of an inner moon, which is nearly circular and lies in the planet's equatorial plane. Until this latest discovery, Saturn was known to have only one irregular, outer satellite, Phoebe, which was discovered by W. Pickering 102 years ago. The great distance that the moons orbit from Saturn, says Nicholson, indicates that the moons were captured into orbit after the planet formed, unlike the larger regular satellites that are thought to have coalesced from a disk of dust and gas that surrounded the planet as it formed. www.news.cornell.edu /releases/Oct00/Saturn.moons.deb.html   (445 words)
