Galaxy clusters are large structures in the universe that consist of hundreds to thousands of galaxies bound together by gravity. They are among the largest known gravitationally-bound structures in the universe and contain not only galaxies but also vast amounts of hot gas, dark matter, and, in some cases, dark energy. Here are some key features of galaxy clusters: 1. **Composition**: A typical galaxy cluster contains a mixture of galaxies, hot intracluster gas (which emits X-rays), and dark matter.

Ismail al-Jazari was a notable Muslim polymath, inventor, engineer, and scholar who lived during the Islamic Golden Age, specifically in the 12th century (approximately 1136–1206). He is most famous for his book "Kitab al-Jami' bayn al-'Ilm wa-l-'Amal al-Nafi' fi Sina'at al-Hiyal" (The Book of Knowledge of Ingenious Mechanical Devices), written in 1206.

Johannes de Sacrobosco, also known as John of Holywood, was a medieval scholar and mathematician, best known for his work on mathematics and astronomy. He was likely born around 1195 and died around 1256. Sacrobosco is often associated with the University of Paris, where he taught and wrote.

MACS0647-JD is a distant galaxy that has garnered significant interest in the field of astronomy due to its extreme distance from Earth. It was discovered as part of a survey of galaxy clusters using the Hubble Space Telescope and other instruments. The galaxy is located approximately 13.3 billion light-years away, which means we see it as it was shortly after the Big Bang.

Abu'l-Hasan ibn Ali al-Qalasadi was a notable figure from the 15th century, primarily recognized for his contributions to the fields of mathematics and astronomy. He was born in 1412 in the city of Qalasād, which is located in present-day Spain. Al-Qalasadi is particularly renowned for his work in the development of trigonometry and the use of astronomical instruments.

Drying is the process of removing moisture from a substance, typically to preserve it, reduce weight, or prevent spoilage. It involves the evaporation of water or other liquids from a material and can take place through various methods, including: 1. **Air Drying**: Using natural airflow to remove moisture, often seen with fruits and herbs. 2. **Sun Drying**: Utilizing sunlight to evaporate moisture, common in warmer climates for drying foods.
