	HubbleSite - NewsCenter - Thackeray's Globules in IC 2944 (01/03/2002) - Introduction
		When radio astronomers observed the faint hiss of molecules within the globules, they realized that the globules are actually in constant, churning motion, moving supersonically among each other.
		This may be caused by the powerful ultraviolet radiation from the luminous, massive stars, which also heat up the gas in the region of glowing hydrogen gas, causing it to expand and stream against the globules, leading to their destruction.
		Despite their serene appearance, the globules may actually be likened to clumps of butter on a red-hot pan.

	Thackeray's Globules - Wikipedia, the free encyclopedia
		Thackeray's Globules are dense, opaque dust clouds in outer space, known as globules, in the star-forming region IC 2944.
		Little is known about the origin and nature of these globules in IC 2944, which were first found by astronomer A.D. Thackeray in 1950.
		Globules are generally associated with large hydrogen-emitting star-formation regions, which give off the glowing light of hydrogen gas.

	Bok globule - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-02)
		A Bok globule is a dark cloud of dense dust and gas in which star formation is taking place.
		Bok globules are found within H II regions, and typically have a mass of about 10–50 solar masses contained within a region about a light year or so across
		Bok globules were first observed by astronomer Bart Bok in the 1940s.

		N this case, the globules were observed in a region known as IC 2944.
		It is likely that these globules are dust and gas clumps that already existed before the birth of the highly massive stars that surrounds them.
		If the stars that surrounds the globules where born later, it is probable that these clumps would have given birth to several low mass stars like the Sun.

	2002 News Releases - Hubble Captures Opaque Globules in Space
		Globules are generally associated with large hydrogen-emitting star-formation regions, which give off the glowing light of hydrogen gas.
		The globules are most likely dense clumps of gas and dust that existed before the hot, massive stars were born.
		The hydrogen-emission image that clearly shows the outline of the dark globules was taken with Hubble's camera in February 1999 by Bo Reipurth, University of Hawaii, Honolulu, and collaborators.

	Hubble Thackeray's Globules Photo
		Although globules like these have been known since Dutch-American astronomer Bart Bok first drew attention to such objects in 1947, little is still known about their origin and nature, except that they are generally associated with areas of star formation, called "HII regions" due to the presence of hydrogen gas.
		Despite their serene appearance, the globules may actually be likened to clumps of butter put onto a red-hot pan.
		It is likely that the globules are dense clumps of gas and dust that existed before the massive O-stars were born.

		I was able to satisfy myself that the ÏrelativeÓ age of the globules to the meteorite was reasonable; that is, it is likely that the globules are younger than the meteorite itself.
		Within those fissures, the globules themselves were not spherical but pancake-shaped, indicating that whatever caused them to form was limited spatially by the walls of the crevice.
		Carbon isotope studies of these globules that look at the content of stable carbon-13 indicate that the globules are probably not terrestrial, and other meteorites recovered from the same area in Antarctica show no such globules.

	Scientific American: Ancient Meteorites from Outer Solar System May Have Provided Raw Materials for Life
		The ratios of the nitrogen and hydrogen isotopes in the hollow globules, measured with a spectrometer, indicate the "organics are completely indigenous to the meteorite" and did not come from Earth contamination, according to team member Michael Zolensky.
		The globules' rare isotope composition and the presence of particles from other stars that managed to survive the chaotic environment of the early solar system indicate the organic matter likely originated in the cold molecular cloud that gave birth to the planets.
		Alternatively, the globules could have originated as icy grains that were exposed to the alkaline solutions in the Tagish Lake meteorite's parent asteroid, hollowing out the center.

		Hepatic Hyaline Globules in an Eclectus Parrot (Eclectus roratus)
		Hyaline globules may form as a result of damage to hepatocyte cell membrane, permeation of blood plasma protein into the hepatocyte due to increased sinusoidal pressure, or acceleration of phagocytosis by hepatocytes.
		Otherwise, the internal structure of the globules is identical to that described in laboratory animals and human beings.

		The isotopic composition of the carbon and oxygen associated with the carbonate globules also indicates that they are indigenous to the meteorite and were not formed during its 13,000-year residence in the Antarctic environment (13).
		The origin of these globules is controversial; Harvey and McSween (11) and Mittlefehldt (4) argued, on the basis of microprobe chemistry and equilibrium phase relationships, that the globules were formed by high-temperature metamorphic or hydrothermal reactions.
		The textures of the carbonate globules are similar to bacterially induced carbonate crystal bundle precipitates produced in the laboratory and in a freshwater pond (57).

	Homogenization
		Homogenization is a mechanical treatment of the fat globules in milk brought about by passing milk under high pressure through a tiny orifice, which results in a decrease in the average diameter and an increase in number and surface area, of the fat globules.
		While most of the fat globule reduction takes place in the first stage, there is a tendency for clumping or clustering of the reduced fat globules.
		Globules are thus torn apart by these eddie currents reducing their average size.

		These globules, which are not observed at first, seem to have the ability to reproduce by budding or elongation, and because of this can form globules in chains.
		The globules of ferment are able to develop very rapidly, because when one collects the total amount of yeast that is produced during the fermentation, one finds that this quantity weighs about seven times the initial quantity of yeast added, which agrees with the microscopic examination.
		It has been reported to me that it is possible to cause the production of globules w hen egg white is diluted in water and heated, and that the globules of yeast arise from a nitrogenous material of animal or vegetable origin, which is present in the wort, and coagulates to form the globules.

		Furthermore, we compare the magnetic field topology with the spatial structure of the globules, in particular with the orientation of the outflows and the orientation of the nonspherical globule cores.
		In the case of the globules B335 and CB 230, the outflows are oriented almost perpendicular to the symmetry axis of the globule cores.
		The magnetic field, however, is aligned with the symmetry axis of the prolate cores in the case of the Bok globules B335 and CB 230, while it is slightly aligned with the outflow axis in the case of the Bok globules CB 26 and CB 54.

	IngentaConnect Extracellular Matrix Globules in Renal Oncocytoma
		Extracellular hyaline globules resulting from abnormal accumulation of matrix components have been described in several pathological conditions, including renal tumors.
		PAS staining greatly facilitated the identification of globules in the remaining six cases, where they were fewer in number.
		We conclude that, although the mere presence of extracellular hyaline globules does not justify a distinction between renal oncocytoma and renal cell carcinoma, the detection of a large number of well-demarcated, roundish extracellular bodies with smooth contours suggests renal oncocytoma.

	CARBONATE GLOBULES FROM SPITSBERGEN, NORWAY: TERRESTRIAL ANALOGS OF THE CARBONATES IN MARTIAN METEORITE ALH84001? (Site not responding. Last check: 2007-11-02)
		In composition, mineralogy and petrology the AMC globules from Spitsbergen are strikingly similar to the carbonate globules in ALH84001.
		The AMC globules occur within interstitial quenched glass and as fracture fillings, although we have not seen replacement fabrics analogous to carbonate rosettes replacing glass in ALH84001.
		Aside from the clay minerals, the principal mineralogical difference between the AMCs and the ALH84001 carbonate rosettes is the presence of concentrated zones of nanophase magnetite in the rosettes, notably absent in the AMCs.

	Fossil Life in ALH 84001?
		As all of McKay’s evidence for martian life is inside the carbonate mineral globules in ALH 84001, it is critical to show that the carbonate mineral globules are martian and that they were formed by liquid water.
		The globules are much older than the meteorite impact event that launched ALH 84001 from Mars on its way to Earth (see Carbonate Age and Cosmic Ray Exposure Age.
		In the carbonate globules of ALH 84001, McKay and his co-workers found microscopic shapes that resemble living and fossil bacteria on Earth; microscopic mineral grains like some produced by living and fossil bacteria on Earth; and organic chemical compounds that resemble the decay products of bacteria on Earth.

		It is in the form of much larger globules, with an average of 3 to 5 micrometers in diameter as shown by the diagram at the title.
		Fat globules in fresh milk are encased ('packaged') in membranes which are lipophilic ('fat loving') on the inside where they are in contact with fat and hydrophilic ('water loving') on the outside where they are in contact with the aqueous medium.
		Each globule is covered with a membrane and the membranes on all fat globules break as the cream is churned to produce butter.

		Fat is mostly in the form of small globule clusters and the protein is in the form of relatively large particles.
		Fat globules originally present in the cheese were extracted from the sample while it was prepared for scanning electron microscopy.

	FIR mapping of bok globules CB202, CB220 and CB236(L1166) with ISOPHOT (Site not responding. Last check: 2007-11-02)
		Therefore, due to their optical appearance, Bok globules are of great interest in the study of star formation, as they are possible candidates for harboring such objects.
		The results from a preliminary analysis of these data, based on single short scans across the globules at 100 and 200 microns, has already been presented (Russell et al, 1998, Star Formation with ISO, p214), but was restricted to an investigation of the morphology of the FIR emission.
		The initial single short scans across these globules have yielded detections of cold dust at 200 microns, but, due to the limited field of view, it has not been possible to determine the total flux from these small extended sources.

	Milk Homogenization and Heart Disease
		Oster postulated that because homogenization reduces the fat globules to a fraction of their original size, the XO is encapsulated by the new outer membranes of the smaller fat globules which form during the homogenization process.
		The milk fat globule membrane from sheep's milk does not separate and butter cannot be made from such milk even though there is twice as much fat in sheep's milk as in cow's milk.
		The original fat globule membrane is lost and a new one is formed that incorporates a much greater portion of casein and whey proteins.

		However, the average size of the globules in their catalogue is not exceeding 5 - 6 arc-minutes in diameter, which makes them perfect objects for observing with new wide-field infrared cameras such as Omega Prime.
		If it happens that the observed object is extended and/or has extended outflows (parsec scale outflows), then there would be roughly a half chance of it appearing fully in the observed area.
		According to this scheme each position on the sky can be imaged four times on the different parts of the detector array in order to allow for a correction of pixel defects.

	MELT/MELT-DIFFUSION IN GLOBULE-BEARING ALKALINE MAGMAS
		Due to differences in temperature and chemistry, the intruding melt is dispersed as globules with diameters from less than a few millimeters to several centimeters.
		Globules can ideally be studied on the latite/trachyte intrusion of the Bittersberg subvolcanic complex where latite is dispersed as globules in a volumetrically dominant trachytic host.
		In these globules trends of element distribution are similar to the intermediate globules: Na (±K) is enriched in the matrix of the globules while the contents of Ca, Mg, Fe, and Ti are decreased relatively to the host rock.

		Due to the diffuse input of lighter elements, the density of the globules was significantly lowerd.
		This rock is completely built up of globules and represents the result of melt/melt-intrusion, diffuse alkali enrichment in the globules, rising up of the globules within the host melt and their aggregation beneath the top of the magma chamber situated in a deeper crustal level generating an alkali enriched extraction melt.
		The presence of analcite and the resorption of olivine in the globules indicate an additional diffuse enrichment of fluids.

		But the microscopic organic globules that make up about one-tenth of one per cent of the object appear to be far older.
		Messenger and colleagues write that the isotopic anomalies in the globules indicate that they were formed in very cold conditions and believe these could not possibly have formed where the meteorite itself had formed.
		Organic matter in meteorites has been a keen subject of study among space scientists because this material is believed to have formed at the beginning of the solar system and may have provided the earth with its building blocks of life.
