PPT-Dark Nebula Joseph Gregory

Dark nebula A type of interstellar cloud that is too dense for light to pass through Mostly comprised of tiny dust particles coated in frozen carbon monoxide and nitrogen Irregular form no defined boundaries.

Cloud would have been mostly hydrogen with some helium – small amounts of the heavier elements.. Hubble Telescope. Compiled by Chris Wolfram, RA University of Maryland-College Park. The Red Spider Nebula. . Huge waves are sculpted in this two-lobed nebula some 3000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.. Note: on Sundays sometimes the Polyeleos is not sung, but rather immediately Nebula (Messier). Parker . Kvenvold. .

Grade World History/Honors. Cobalt Institute of Math and Science. Pope Gregory VII. The growing role of church leaders in Europe’s politics caused many arguments over who was in charge. Kings wanted church leaders to obey them, while the pope claimed he could crown kings. In 1073 Gregory VII was elected pope. He wanted to stop nobles and kings from interfering in church affairs. He issued a decree, or order, forbidding kings from appointing high-ranking church officials. The pope’s decree angered Henry IV, the Holy Roman Emperor. For many years, the Holy Roman emperor had appointed bishops in Germany. Without them, Henry IV risked losing power to the nobles. Henry refused to obey Gregory. He declared that Gregory was no longer pope. Gregory then stated that Henry was no longer emperor. He excommunicated Henry. This means to exclude a person from church membership. Catholics believe that if they were excommunicated, they could not go to heaven. When the German nobles defended the pope, Henry backed down. He traveled to Italy and stood barefoot in the snow outside the pope’s castle asking to be forgiven. Gregory forgave Henry, but the German nobles still chose a new king. When Gregory accepted the new king as emperor, Henry went to war. He captured Rome and named a new pope. Gregory’s allies drove out Henry’s forces, but the dispute was not resolved. In 1122, a new pope and the German king finally agreed that the pope could choose bishops, but only the emperor could give them jobs in government. This deal, called the Concordat of Worms, was signed in the city of Worms. A concordat is an agreement between the pope and the ruler of a country. By the time Innocent III became pope in 1198, the Catholic Church was at the height of its power. Innocent was able to control kings. If a ruler did not obey, Innocent would excommunicate him or issue an interdict against the ruler’s people. An interdict forbids priests from providing Christian rituals to a group of people. The pope anticipated that by using an interdict, local people would pressure their ruler to obey.. Spiral Nebulae: . A Huge Challenge!. The . ‘. Great Debate. ’.
