Vega vs Medina

Informations

Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun". Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when its declination will be +86° 14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive, its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. Vega is also a variable star that varies slightly in brightness. It is rotating rapidly with a velocity of 236 km/s at the equator. This causes the equator to bulge outward due to centrifugal effects, and, as a result, there is a variation of temperature across the star's photosphere that reaches a maximum at the poles. From Earth, Vega is observed from the direction of one of these poles.Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of collisions between objects in an orbiting debris disk, which is analogous to the Kuiper belt in the Solar System. Stars that display an infrared excess due to dust emission are termed Vega-like stars.

Medina, officially Al Madinah Al Munawwarah (Arabic: المدينة المنورة‎, romanized: al-Madinat al-Munawwarah, lit. 'The Enlightened City'), commonly simplified as Madīnah or Madinah, is one of the three holiest cities in Islam and the capital of the Medina Region of Saudi Arabia. The 2020 estimated population of the city is 1,488,782, making it the fourth-most populous city in the country. Located at the core of the Madinah Province in the western reaches of the country, the city is distributed over 589 square kilometers (227 square miles), 293 km2 (117 sq. mi.) of which constitutes the city's urban area, while the rest is occupied by the Hejaz mountain range, empty valleys, agricultural spaces, older dormant volcanoes and the Nafud desert. The city is considered to be the second-holiest of three cities in Islamic tradition, the other two being Mecca and Jerusalem. The Masjid al-Nabawi ('Prophet's Mosque') built by Muhammad in 622 CE, is of exceptional importance in Islam and is the site of burial of the last Islamic prophet. Muslims visit his rawdhah in what is known as Ziyarat at least once in their lifetime, although this is not obligatory. The original name of the city before the advent of Islam was Yathrib and it is referred to by the same name in the Qur'an in Chapter 33, al-Ahzab (The Confederates). It was renamed Madīnat an-Nabī (City of the Prophet or The Prophet's City) after Muhammad's death and later al-Madinah al-Munawwarah (The Enlightened City), before being simplified and shortened to its modern name, Madinah (The City), written in English as Medina. Saudi Arabian road signage uses Madinah and al-Madinah al-Munawwarah interchangeably.The city is known to have existed for over 1500 years before Muhammad's migration from Mecca, otherwise known as the Hijrah.

Medina was the capital of a rapidly increasing Muslim caliphate under Muhammad's leadership, serving as its base of operations and as the cradle of Islam, where Muhammad's Ummah (Community), composed of the citizens of Madinah, known as the Ansar and those who immigrated with Muhammad, known as the Muhajirun, collectively known as the Sahaba, gained huge influence. Medina is home to three prominent mosques, namely al-Masjid an-Nabawi, Masjid Quba'a, and Masjid al-Qiblatayn, with the masjid at Quba'a being the oldest in Islam. A larger portion of the Qur'an was revealed in Medina in contrast to the earlier Meccan surahs.Much like most of the Hejaz, Medina has seen numerous exchanges of power within its comparatively short existence. The region is known to have been controlled by Arabian Jewish tribes (up to the 5th century CE), the 'Aws and Khazraj (up to Muhammad's arrival), Muhammad and the Rashidun (622–660 CE), Umayyads (660–749 CE), Abbasids (749–1254 CE), the Mamluks of Egypt (1254–1517 CE), the Ottomans (1517–1805 CE), the First Saudi State (1805–1811 CE), Muhammad Ali Pasha (1811–1840 CE), the Ottomans for a second time (1840–1918), the Hashemite Sharifate of Mecca (1918–1925 CE) and finally is in the hands of the modern-day Kingdom of Saudi Arabia (1925–present CE).In addition to visiting for Ziyarah, tourists come to visit the other prominent mosques and landmarks in the city that hold religious significance such as Mount Uhud, Al-Baqi' cemetery and the Seven Mosques among others. Recently, after the Saudi conquest, the Saudis carried out a demolition of several tombs and domes in and around the region fearing these might become sites of association of others in worship beside Allah (shirk).
