A collective noun (or collective name) is a name which denotes or represents a number of individual items. For example, a number of sheep together is known as a 'flock'. The word 'flock' is the collective noun for a number of sheep. Some items have multiple collective nouns, for example a collection of goats can be known as a 'herd', a 'tribe' or a 'trip'.

The Milky Way is the large, disk-shaped aggregation of stars, or galaxy , that includes the sun and its solar system. Its name is derived from its appearance as a faintly luminous band that stretches across earth's sky at night. This band is the disk in which the solar system lies. Its hazy appearance results from the combined light of stars too far away to be distinguished individually by the unaided eye. The individual stars that are distinct in the sky are those in the Milky Way galaxy that lie sufficiently close to the solar system to be discerned separately. From the middle northern latitudes, the Milky Way is best seen on clear, moonless, summer nights, when it appears as a luminous, irregular band circling the sky from the north-eastern to the south-eastern horizon. It extends through the constellations Perseus, Cassiopeia, and Cepheus. In the region of the Northern Cross it divides into two streams: the western stream, which is bright as it passes through the Northern Cross, fades near Ophiuchus, or the Serpent Bearer, because of dense dust clouds, and appears again in Scorpio; and the eastern stream, which grows brighter as it passes southward through Scutum and Sagittarius. The brightest part of the Milky Way extends from Scutum to Scorpio, through Sagittarius. The centre is in the direction of Sagittarius and is about 26,000 light-years from the sun. Research Milky Way
Douglas Adams was an English author. He was born in 1952 at Cambridge and died in 2001 of a heart-attack. Best remembered for his science fiction comedy, 'The Hitchhiker's Guide to The Galaxy', Douglas Adams also wrote and edited many of the scripts for the BBC television series 'Doctor Who' in which his subtle English humour and outstanding creativity and originality helped to make the series such an international success.

Walter Baade was a German-born American astronomer. He was born in 1893 and died in 1960. He proposed the existence of two stellar populations. He deduced this from photographs taken of the satellites of the AndromedaGalaxy (M31). Young stars belonging to the spiral arms of galaxies he called PopulationI stars and the old stars associated with the more central regions he called Population II stars. Baade reinvestigated the period-luminosity law for variable stars which can be used to measure the distances of nearby galaxies. In 1952 he proposed a revision of the law which meant that the estimated distances of these galaxies had to be doubled. Research Walter Baade

A nebula is a cloud of gas and dust in space. Before the invention of the telescope, the term nebula was applied to all celestial objects of a diffuse appearance. As a result, many objects now known to be star clusters or galaxies were originally called nebulas.
Nebulas exist within other galaxies as well as in our own Milky Waygalaxy. They are classified as planetary nebulas, supernova remnants, and diffuse nebulas, including reflecting, emission, and dark nebulas. Small, very bright nebulas called Herbig-Haro objects are found in dense interstellar clouds and are probably the products of gas jets expelled by new stars in the process of formation. Planetary nebulas, or planetaries, are so called because many of them superficially resemble planets through telescopes. They are actually shells of material that an old average star sheds during a late, red giant stage in its evolution, before becoming a white dwarf. The Ring nebula of the constellationLyra, a typical planetary, has a rotational period of 132, 900 years and a mass calculated to be about 14 times that of the earth's sun. Several thousand planetaries have been discovered in the Milky Way. More spectacular but fewer in number are nebulas that are the fragments of supernova explosions, perhaps the most famous of which is the Crab nebula in Taurus, now fading at the rate of about 0.4 percent per year. Nebulas of this kind are strong emitters of radio waves, as a result of the explosions that formed them and the probable pulsar remnants of the original star. Diffuse nebulas are extremely large structures, often many light-years wide, that have no definite outline and a tenuous, cloudlike appearance. They are either luminous or dark. The former shine as a result of the light of neighbouring stars. They include some of the most striking objects in the sky, such as the Great nebula in Orion. The tremendous streams of matter in the diffuse nebulas are intermingled in violent, chaotic currents. Many thousands of luminous nebulas are known. Spectral studies show that light emanating from them consists of reflected light from stars and also, in so-called emission nebulas, of stimulated radiation of ionised gases and dust from the nebulas themselves.
Dark, diffuse nebulas are observed as nonluminous clouds or faintly luminous, obscuring portions of the Milky Way and too distant from the stimulation of neighbouring stars to reflect or emit much light of their own. One of the most famous dark nebulas is the Horsehead nebula in Orion, so named for the silhouette of the dark mass in front of a more luminous nebular region. The longest dark rift observed on photographic plates of the star clouds of the Milky Way is a succession of dark nebulas. Both dark nebulas and luminous nebulas are considered likely sites for the processes of dust-cloud condensation and the formation of new stars. Research Nebula
