In the Name of Allah---the Most Beneficent, the Most Merciful.
A galaxy is a vast system of stars, stellar remnants, interstellar gas, dust, dark matter, and other celestial objects, all bound together by gravity.
A galaxy is a vast system of stars, stellar remnants, interstellar gas, dust, dark matter, and other celestial objects, all bound together by gravity. The observable universe contains hundreds of billions of galaxies, each varying in size, structure, and composition. Galaxies are classified into several main types based on their shape and appearance.
Types of Galaxies
Spiral Galaxies
Structure: Spiral galaxies consist of a flat, rotating disk containing stars, gas, and dust, along with a central bulge made up mostly of older stars. The disk often features spiral arms that emanate from the central bulge.
Subtypes:
Normal Spirals (Sa, Sb, Sc): Classified based on the tightness of their spiral arms and the size of their central bulge. Sa galaxies have tightly wound arms and large bulges, while Sc galaxies have loosely wound arms and smaller bulges.
Barred Spirals (SBa, SBb, SBc): Similar to normal spirals but have a central bar structure made up of stars. The arms of barred spirals originate from the ends of the bar.
Examples: The Milky Way, Andromeda (M31).
Elliptical Galaxies
Structure: Elliptical galaxies range from nearly spherical (E0) to highly elongated (E7). They have a smooth, featureless light profile and lack the spiral arms seen in spiral galaxies.
Characteristics: They contain older, red stars and have very little gas or dust, which means minimal new star formation. These galaxies are more common in large galaxy clusters.
Examples: M87, Centaurus A.
Lenticular Galaxies (S0)
Structure: Lenticular galaxies are an intermediate form between spiral and elliptical galaxies. They have a central bulge and a disk like spirals but lack significant spiral arms.
Characteristics: They contain older stars and very little interstellar matter, leading to minimal new star formation.
Examples: NGC 5866.
Irregular Galaxies
Structure: Irregular galaxies do not fit into the categories of spiral or elliptical galaxies. They have an irregular shape with no defined structure.
Characteristics: Often rich in gas and dust, leading to significant star formation. They may have been distorted by gravitational interactions or collisions with other galaxies.
Examples: Large Magellanic Cloud, Small Magellanic Cloud.
Additional Classification
Dwarf Galaxies
Structure: Smaller in size and lower in luminosity compared to regular galaxies. They can be found in various forms, including dwarf ellipticals, dwarf irregulars, and dwarf spheroidals.
Characteristics: Dwarf galaxies often orbit larger galaxies and can be abundant in galaxy clusters.
Examples: Draco Dwarf, Fornax Dwarf.
Other Notable Types
Peculiar Galaxies
Structure: Galaxies with unusual shapes or features that do not fit into the standard categories, often due to gravitational interactions, mergers, or other processes.
Examples: Antennae Galaxies (NGC 4038/NGC 4039).
Ring Galaxies
Structure: These galaxies have a ring-like structure of stars and gas surrounding a central core. The ring is typically formed by a collision with another galaxy.
Examples: Hoag’s Object.
Galaxies are not only fascinating in their diverse structures but also crucial to understanding the large-scale structure of the universe. Each type of galaxy provides insights into the processes of cosmic evolution, star formation, and the dynamics of gravitational interactions.
In the Name of Allah---the Most Beneficent, the Most Merciful. The Qur’an provides insights into the origins of human civilization, particularly through the narrative of Prophet Noah (Nuh, عليه السلام) and the Great Flood. According to Surah Hud (11:44) , after the floodwaters receded, Noah’s Ark came to rest on Mount al-Judi , which is located in Upper Al-Jazirah , near the foothills of the Taurus Mountains in modern-day southeastern Turkey and northern Iraq. This region, often identified as Mesopotamia , has historically been regarded as one of the earliest centers of human settlement and civilization. Al-Jazirah in the Context of the Qur’an Al-Jazirah, meaning “The Island” in Arabic, refers to the land between the Tigris and Euphrates rivers . This area, covering parts of modern Iraq, Syria, and Turkey , is known for its fertile soil, abundant water resources, and strategic location , making it an ideal place for the emergence of ...
In the Name of Allah---the Most Beneficent, the Most Merciful. 1. Introduction The Islamic system of governance is neither a theocracy run by priests nor a secular democracy founded upon popular sovereignty. It is a moral–legal system rooted in the sovereignty of Allah ( ḥākimiyyat-e-Ilāhiyyah ) , where human authority operates as a trust ( amānah) to implement divine law and uphold justice. The Qur’an declares: “The command (ḥukm) belongs to none but Allah.” (Yūsuf 12:40) This verse establishes that ultimate authority to legislate belongs to God alone. The human ruler, called Imām or Khalīfah , is therefore not sovereign in his own right but an executor of the divine will through the Sharī‘ah . 2. The Foundational Principle: Sovereignty of Allah The foundation of the Islamic polity rests on the recognition that Allah alone is the Lawgiver and Sovereign . The Qur’an states: “It is not for a believing man...
In the Name of Allah---the Most Beneficent, the Most Merciful. The Qur’an did not present mathematics as a formal or technical discipline in the way later scholars would define it; rather, it subtly reoriented human cognition toward quantification, proportionality, and precise measurement . Through its repeated emphasis on counting, fractions, multiples of ten, and the careful measurement of time, wealth, and obligations, the Qur’an trained the human mind to think in structured, measurable, and verifiable terms . Concepts such as inheritance shares, zakāh calculations, and ritual durations required accurate division, addition, and proportional reasoning, effectively making arithmetic a practical necessity in daily life. This cognitive framework created a fertile environment in which applied mathematics could flourish, as humans were already habituated to reason in numbers, ratios, and totals. By embedding numeracy into law, commerce, and ritual, the Qur’an not on...
In the Name of Allah---the Most Beneficent, the Most Merciful. Pakistan’s Strategic Canals Project, aimed at diverting water from the Jhelum and Chenab rivers into the Cholistan region, has sparked an ongoing canal conflict —not merely between provinces but between competing visions of national development and federal equity. At the heart of this complex issue is the challenge of how to expand agricultural productivity in barren regions like Cholistan while ensuring fair and sustainable water distribution among the country’s riparian provinces, particularly Sindh, which lies downstream on the Indus River System. The Strategic Canals Project: A National Vision Supporters of the project argue that the Strategic Canals Plan is not a unilateral initiative of Punjab, but a nationally approved and endorsed program aimed at revitalizing Pakistan’s agricultural sector. President Asif Ali Zardari, among others, has backed the initiative as part of a broader strategy to ensure food se...
In the Name of Allah---the Most Beneficent, the Most Merciful. Abstract This paper presents an empirical validation of a star‑anchored (sidereal) Muslim Horoscope system and the Universal Hijri Calendar (UHC) through repeatable astronomical tests. Using Metonic-cycle recurrences, heliacal star phenomena, and modern sidereal longitudes of key stellar anchors (notably Al‑Thurayyā / the Pleiades), we demonstrate that both systems converge on the same physical sky reality without reliance on tropical conventions. The results show simultaneous coherence between lunar mansions (manāzil al‑qamar), Hijri date structure, and observed stellar behavior, affirming the classical Islamic astronomical framework as empirically grounded. 1. Introduction Islamic astronomical practice historically integrated observation (ruʾyah), cyclic reckoning, and stellar anchoring. Over time, confusion arose due to the conflation of tropical zodiacal frameworks with sidereal stellar systems. T...
In the Name of Allah---the Most Beneficent, the Most Merciful. The 2025 ten-year U.S.–India Defence Framework was announced following a bilateral meeting between U.S. Defence Secretary Pete Hegseth and Indian Defence Minister Rajnath Singh in Kuala Lumpur . The venue and the ministerial-level representation indicate that the pact was the outcome of structured, institutional diplomacy rather than a sudden geopolitical maneuver. The level of the participating ranks —defence ministers rather than heads of state or government—underscores that the agreement is formal, procedural, and evolutionary in nature , not an outbreaking or revolutionary realignment. ( BBC ) This signals that both sides view the framework as a continuation and consolidation of ongoing cooperation rather than the launch of a new strategic alliance. It reflects bureaucratic maturity within the defence establishments of both countries, translating years of accumulated ...
In the Name of Allah---the Most Beneficent, the Most Merciful. Is Mercy-Killing Allowed in Islam? Euthanasia is the act of intentionally ending the life of a person who is suffering from a terminal illness or unbearable pain, often through the administration of lethal drugs. It is also referred to as assisted dying or mercy killing. Euthanasia can be voluntary, where the person who wishes to die makes a conscious decision to end their life, or non-voluntary, where a decision is made on behalf of a person who is unable to express their wishes, such as a person in a coma or with severe dementia. Euthanasia is a controversial and heavily debated issue, with arguments for and against its legalization and use. Let me explain: Is Mercy-Killing Allowed in Islam? Euthanasia, or intentionally ending the life of a person who is suffering from a terminal illness or unbearable pain, is not allowed in Islam. Islamic teachings consider human life to be sacred, and the taking of a life, whether ...
