A globular cluster is a spherical collection of stars that orbits a galactic core. Globular clusters are tightly bound by gravity, which gives them their spherical shapes, high stellar densities toward their centers; the name of this category of star cluster is derived from globulus -- a small sphere. A globular cluster is known as a globular. Globular clusters are found in the halo of a galaxy and contain more stars, are much older than the less dense open clusters, which are found in the disk of a galaxy. Globular clusters are common. Larger galaxies can have more: The Andromeda Galaxy, for instance, may have as many as 500; some giant elliptical galaxies, such as M87, have as many as 13,000 globular clusters. Every galaxy of sufficient mass in the Local Group has an associated group of globular clusters, every large galaxy surveyed has been found to possess a system of globular clusters; the Sagittarius Dwarf galaxy, the disputed Canis Major Dwarf galaxy appear to be in the process of donating their associated globular clusters to the Milky Way.
This demonstrates. Although it appears that globular clusters contain some of the first stars to be produced in the galaxy, their origins and their role in galactic evolution are still unclear, it does appear clear that globular clusters are different from dwarf elliptical galaxies and were formed as part of the star formation of the parent galaxy, rather than as a separate galaxy. The first known globular cluster, now called M 22, was discovered in 1665 by Abraham Ihle, a German amateur astronomer. However, given the small aperture of early telescopes, individual stars within a globular cluster were not resolved until Charles Messier observed M 4 in 1764; the first eight globular clusters discovered are shown in the table. Subsequently, Abbé Lacaille would list NGC 104, NGC 4833, M 55, M 69, NGC 6397 in his 1751–1752 catalogue; when William Herschel began his comprehensive survey of the sky using large telescopes in 1782 there were 34 known globular clusters. Herschel discovered another 36 himself and was the first to resolve all of them into stars.
He coined the term "globular cluster" in his Catalogue of a Second Thousand New Nebulae and Clusters of Stars published in 1789. The number of globular clusters discovered continued to increase, reaching 83 in 1915, 93 in 1930 and 97 by 1947. A total of 152 globular clusters have now been discovered in the Milky Way galaxy, out of an estimated total of 180 ± 20; these additional, undiscovered globular clusters are believed to be hidden behind the gas and dust of the Milky Way. Beginning in 1914, Harlow Shapley began a series of studies of globular clusters, published in about 40 scientific papers, he examined the RR Lyrae variables in the clusters and used their period–luminosity relationship for distance estimates. It was found that RR Lyrae variables are fainter than Cepheid variables, which caused Shapley to overestimate the distances of the clusters. Of the globular clusters within the Milky Way, the majority are found in a halo around the galactic core, the large majority are located in the celestial sky centered on the core.
In 1918, this asymmetrical distribution was used by Shapley to make a determination of the overall dimensions of the galaxy. By assuming a spherical distribution of globular clusters around the galaxy’s center, he used the positions of the clusters to estimate the position of the Sun relative to the galactic center. While his distance estimate was in significant error, it did demonstrate that the dimensions of the galaxy were much greater than had been thought. Shapley's measurements indicated that the Sun is far from the center of the galaxy contrary to what had been inferred from the nearly distribution of ordinary stars. In reality, most ordinary stars lie within the galaxy's disk and those stars that lie in the direction of the galactic centre and beyond are thus obscured by gas and dust, whereas globular clusters lie outside the disk and can be seen at much further distances. Shapley was subsequently assisted in his studies of clusters by Henrietta Swope and Helen Battles Sawyer. In 1927–1929, Shapley and Sawyer categorized clusters according to the degree of concentration each system has toward its core.
The most concentrated clusters were identified as Class I, with successively diminishing concentrations ranging to Class XII. This became known as the Shapley–Sawyer Concentration Class. In 2015, a new type of globular cluster was proposed on the basis of observational data: dark globular clusters; the formation of globular clusters remains a poorly understood phenomenon and it remains uncertain whether the stars in a globular cluster form in a single generation or are spawned across multiple generations over a period of several hundred million years. In many globular clusters, most of the stars are at the same stage in stellar evolution, suggesting that they formed at about the same time. However, the star formation history varies from cluster to cluster, with some clusters showing distinct populations of stars. An example of this is the globular clusters in the Large Magellanic Cloud that exhibit a bimodal population. During their youth, these LMC clusters may have encountered giant molecular clouds that triggered a second round of star f

God in Search of Man: A Philosophy of Judaism is a work on Jewish philosophy by Rabbi Dr. Abraham Joshua Heschel. Heschel saw the work's title as a paradoxical formula, rooted in the rabbinic tradition, summarizing human history as seen in the Bible: God in search of man. In God in Search of Man Heschel articulates a belief in a personal God who sees humankind as partners in creation, forging a world filled with justice and compassion. God in Search of Man: A Philosophy of Judaism is a companion volume to Heschel's earlier work Man Is Not Alone: A Philosophy of Religion where he delineates experiential and philosophical interpretations of Jewish views of humanity and the world, while in God in Search of Man Heschel focuses on Jewish revelation and orthopraxis. In God in Search of Man, Heschel discusses the nature of religious thought, how thought becomes faith, how faith creates responses in the believer, he discusses ways that people can seek God's presence, the "radical amazement" that we receive in return.
He offers a criticism of nature worship. Heschel, like his teacher Martin Buber, stresses the personal relationship between God and mankind, defined by Heschel as the Godly pathos and mankind's radical amazement; the first section concludes with a study of Jews as a chosen people. Section two deals with the idea of revelation, what it means for one to be a prophet; this section gives us Heschel's idea of revelation as an event, as opposed to a process. This relates to Israel's commitment to God. Section three discusses his views of how a Jew should understand the nature of Judaism as a religion. Heschel discusses and rejects the idea that mere faith alone is enough, but cautions against rabbis he sees as adding too many restrictions to Jewish law, he discusses the need to correlate ritual observance with spirituality and love, the importance of Kavanah when performing mitzvot. He engages in a discussion of religious behaviorism—when people strive for external compliance with the law, yet disregard the importance of inner devotion.
