This word means "milky," because, in Greek mythology, it is the milk spurt from the breasts of Hera, Zeus's wife, while she was nursing the baby Heracles. The Romans inherited the Greeks' gods and mythology, and called this spectacular structure "Via Lactea," which means "Milky Way."...
This would mean that the total number of stars in the universe are greater than the number of grains of sand on Earth. What is the name of our galaxy? Our galaxy is a spiral galaxy called the Milky Way. It is called the Milky Way because of the milky appearance it makes in the ...
ALL of the matter and energy that exists What is the universe? The star at the center of our solar system What is the Sun? The Milky Way galaxy Which galaxy is our solar system a part of? The Sun is much closer than other stars Why does the Sun provide more light and energy to Ea...
2 DYNAMICS OF MULTIPLE STELLAR COMPONENTS 2.1 The case of Andromeda II And II is a dSph satellite of M31 located at a distance of ∼ 650 kpc from the Milky Way (McConnachie et al. 2004, 2005). McConnachie & Irwin (2006) present its sur- ...
Milky Way GalaxyGalactic EvolutionMass To Light RatiosSolar NeighborhoodThe determination of the relative masses of the disks, bulges and dark halos of galaxies has received considerable attention in the present proceedings. The attention is well deserved, since any attempt to understand the formation ...
The halo of the Milky Way provides unique elemental abundance and kinematic information on the first objects to form in the Universe, and this information can be used to tightly constrain models of galaxy formation and evolution. Although the halo was once considered a single component, evidence ...
Milky Way GalaxyWe investigate statistically the relative velocities of the ionized gas in HII regions and the neutral gas in the molecular clouds associated with them for 151 optical HII regions in our Galaxy. The...doi:10.1007/978-94-009-7778-5_28M. Fich...
Milky Way GalaxyProtonsShock WavesSupernova RemnantsRe-acceleration of cosmic rays in interstellar space has been studied in detail in order to examine the behaviour of the ratios of secondary to primary nuclei in cosmic radiation. It is found that modest acceleration in a confinement region, where...
Context. The Andromeda galaxy is the best-known large galaxy besides our own Milky Way. Several images and studies exist at all wavelengths from radio to hard X-ray. Nevertheless, only a few observations are available in the microwave range where its average radio emission reaches the minimum....
Another method involves the isophotal radius measurement [2], determining the size attributed to a galaxy component according to the corresponding surface brightness level. A way to characterise the light distribution independent of the light profile is through the concentration measure, defined by the...
