HUBBLE - SPATIU - NEBULE - NGC 7027 - NCG 6302


June 19, 2020: PICTURE SHOWS: Hubble was recently retrained on NGC 6302, known as the ''Butterfly Nebula,'' to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor ''wings'' of gas. The observations highlight a new pattern of near-infrared emission from singly ionized iron, which traces an S-shape from lower left to upper right. This iron emission likely traces the central star system’s most recent ejections of gas, which are moving at much faster speeds than the previously expelled mass. The star or stars at its center are responsible for the nebula's appearance. In their death throes, they have cast off layers of gas periodically over the past couple thousand years. The ''wings'' of NGC 6302 are regions of gas heated to more than 36,000 degrees Fahrenheit that are tearing across space at more than 600,000 miles an hour. NGC 6302 lies between 2,500 and 3,800 light-years away in the constellation Scorpius.........STORY CAPTION:..NASA announced Thursday (18 June) Hubble has provided a holistic view of stars ''gone haywire''. ..As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Astronomers have employed Hubble's full range of imaging capabilities to dissect such crazy fireworks happening in two nearby young planetary nebulas. NGC 6303 is dubbed the Butterfly Nebula because of its wing-like appearance. In addition, NGC 7027 resembles a jewel bug, an insect with a brilliantly colourful metallic shell. .. The researchers have found unprecedented levels of complexity and rapid changes in jets and gas bubbles blasting off of the stars at the centers of both nebulas. Hubble is allowing the researchers to converge on an understanding of the mechanisms underlying the chaos...When: 19 Jun 2020.C
