Given the question: Information: - A nebula (Latin for "cloud"; pl. nebulae, nebul, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, "nebula" was a name for any diffuse astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was once referred to as the "Andromeda Nebula" (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble and others. - Serpens ("the Serpent", Greek ) is a constellation of the northern hemisphere. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations defined by the International Astronomical Union. It is unique among the modern constellations in being split into two non-contiguous parts, Serpens Caput (Serpent Head) to the west and Serpens Cauda (Serpent Tail) to the east. Between these two halves lies the constellation of Ophiuchus, the "Serpent-Bearer". In figurative representations, the body of the serpent is represented as passing behind Ophiuchus between Mu Serpentis in "Serpens Caput" and Nu Serpentis in "Serpens Cauda". - '' Pillars of Creation '' is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula , some 7,000 light years from Earth . They are so named because the gas and dust are in the process of creating new stars , while also being eroded by the light from nearby stars that have recently formed . Taken on April 1 , 1995 , it was named one of the top ten photographs from Hubble by Space.com . The astronomers responsible for the photo were Jeff Hester and Paul Scowen from Arizona State University . In 2011 , the region was revisited by ESA 's Herschel Space Observatory . - The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 174546. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" photographed by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the Pillars of Creation. - Arizona State University (commonly referred to as ASU or Arizona State) is a public metropolitan research university on five campuses across the Phoenix, Arizona, metropolitan area, and four regional learning centers throughout Arizona. The 2016 university ratings by "U.S. News & World Report" rank ASU No. 1 among the Most Innovative Schools in America for the second year in a row. - Phoenix is the capital and most populous city of the U.S. state of Arizona. With 1,563,025 people, Phoenix is the sixth most populous city nationwide, the most populous state capital in the United States, and the only state capital with a population of more than one million residents. - Arizona (O'odham: "Al onak" [ai onak]) is a state in the southwestern region of the United States. It is also part of the Western United States and the Mountain West states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is one of the Four Corners states. It has borders with New Mexico, Utah, Nevada, California, and Mexico, and one point in common with the southwestern corner of Colorado. Arizona's border with Mexico is 389 miles (626km) long, on the northern border of the Mexican states of Sonora and Baja California. - A low Earth orbit (LEO) is an orbit around Earth with an altitude between (orbital period of about 88 minutes), and (about 127 minutes). Objects below approximately will experience very rapid orbital decay and altitude loss. - The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. After reading the paragraphs above, we are interested in knowing the entity with which 'pillars of creation' exhibits the relationship of 'constellation'. Find the answer from the choices below. Choices: - andromeda - leo - phoenix - serpens
The answer is:
serpens
