Albert Einstein voorspelde het fenomeen der zwaartekrachtlenzen en in 1979 werd er voor het eerst eentje gezien bij de quasar Q0957+651: het effect dat een relatief zeer sterk zwaartekrachtveld, zoals dat van een cluster van sterrenstelsels, het licht van een daarachterliggend voorwerp afbuigt én versterkt.…

An article published in "Astrophysical Journal" describes a research showing a link between a supermassive black hole and the galaxy that hosts it. A team of researchers used the ALMA radio telescope to study a galaxy in the heart of the Phoenix Cluster which has at its core a supermassive black hole that emits electromagnetic radiation jets that are stimulating the birth of new stars.

Phoenix Arizona - The Best Place To Visit

Early records : For on summit of 2,000 years, the Hohokam peoples occupied the home that would become Phoenix.The Hohokam created a propos 135 miles (217 km) of irrigation canals, making the desert on fire arable. Paths of these canals would well ahead become used for the objector Arizona Canal, Central Arizona Project Canal, and the Hayden-Rhodes Aqueduct. The Hohokam furthermore carried out extensive trade subsequent to the neighboring to Anasazi, Mogollon and Sinagua, as nimbly as later the more inattentive Mesoamerican civilizations. It is believed that surrounded by 1300 and 1450, periods of drought and unexpected floods led to the Hohokam civilization's handing greater than of the place. Local Akimel O'odham settlements, thought to be the descendants of the formerly urbanized Hohokam, concentrated in this area the Gila River.

When the Mexican-American War finished in 1848, Mexico sold its northern zone to the United States and residents became U.S. citizens. The Phoenix place became share of the New Mexico Territory. In 1863 the mining town of Wickenburg was the first to be customary in what is now Maricopa County, to the north-west of advanced Phoenix. At the era Maricopa County had not yet been incorporated: the home was within Yavapai County, which included the major town of Prescott to the north of Wickenburg.

The U.S. Army created Fort McDowell about the Verde River in 1865 to forestall Native American uprisings. The fort decided a camp vis--vis the subject of the south side of the Salt River by 1866, which was the first non-original submission in the valley after the decline of the Hohokam. In merged years, subsidiary comprehensible settlements would form and integrate to become the city of Tempe, but this community was incorporated after Phoenix.

Climate : Phoenix has a warm desert climate (Kppen climate classification BWh), typical of the Sonoran Desert in which it lies. Phoenix has long, the whole demonstrative summers and hasty, mild winters. The climate is arid, behind loads of sunshine and determined skies. Average high temperatures in summer are the hottest of any major city in the United States, and the city has more days in addition to than the temperature exceeds 100 F (38 C) than any auxiliary city in the United States.On average (19812010), there are 107 days annually subsequent to a high of at least 100 F (38 C), including most days from late May through in the future October. Highs peak 110 F (43 C) an average of 18 days during the year Every hours of day from June 10 through August 24, 1993, the temperature in Phoenix reached 100 F (38 C) or more, the longest continuous number of days (76) in the city's history. Officially, the number of days as soon as a high of at least 100 F (38 C) has historically ranged from 48 in 1913 to 143 in 1989. For comparison, by now 1870, New York City has seen a temperature of 100 F (38 C) or more a solution of by yourself 59 days. On June 26, 1990, the temperature reached an all-era recorded high of 122 F (50 C).However, despite Phoenix's allegation to the most extreme temperatures, it does not have the highest average temperature. In that admire it comes in second to Miami, considering than an average daily temperature of 75 F (24 C), compared to Miami's 77 F (25 C).[66]

Phoenix Cluster: A Fresh Perspective on an Extraordinary Cluster of Galaxies

New observations of the "Phoenix Cluster" at X-ray, optical, and ultraviolet wavelengths provide new details about this remarkable system.

The Phoenix Cluster holds several records for properties of a galaxy cluster.

X-rays from Chandra reveal giant holes, or cavities, in the hot gas that pervades the cluster.

Massive filaments of gas and dust surround the X-ray cavities and may play a role in the extreme star formation seen in the cluster.

Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the Universe held together by gravity.
