New observations about the age of some globular clusters in our Milky Way galaxy have cast doubt on a long-held theory about how the galaxy was formed. The Milky Way contains about 125 globular clusters (compact groups of anywhere from several tens of thousands to perhaps a million stars) distributed in a roughly spherical halo around the galactic nucleus. The stars in these clusters are believed to have been born during the formation of the galaxy, and so may be considered relics of the original galactic nebula, holding vital clues to the way the formation took place.The conventional theory of the formation of the galaxy contends that roughly 12 to 13 billion years ago the Milky Way formed over a relatively short time (about 200 million years) when a spherical cloud of gas collapsed under the pressure of its own gravity into a disc surrounded by a halo. Such a rapid formation of the galaxy would mean that all stars in the halo should be very nearly the same age.However, the astronomer Michael Bolte has found considerable variation in the ages of globular clusters. One of the clusters studied by Bolte is 2 billions years older than most other clusters in the galaxy, while another is 2 billion years younger. A colleague of Bolte contends that the cluster called Palomar 12 is 5 billion years younger than most other globular clusters.To explain the age differences among the globular clusters, astronomers are taking a second look at andldquo;renegadeandrdquo; theories. One such newly fashionable theory, first put forward by Richard Larson in the early 1970andrsquo;s, argues that the halo of the Milky Way formed over a period of a billion or more years as hundreds of small gas clouds drifted about, collided, lost orbital energy, and finally collapsed into a centrally condensed elliptical system.

The conventional theory of the formation of the galaxy contends that roughly 12 to 13 billion years ago the Milky Way formed over a relatively short time (about 200 million years) when a spherical cloud of gas collapsed under the pressure of its own gravity into a disc surrounded by a halo. Such a rapid formation of the galaxy would mean that all stars in the halo should be very nearly the same age.

However, the astronomer Michael Bolte has found considerable variation in the ages of globular clusters. One of the clusters studied by Bolte is 2 billions years older than most other clusters in the galaxy, while another is 2 billion years younger. A colleague of Bolte contends that the cluster called Palomar 12 is 5 billion years younger than most other globular clusters.

To explain the age differences among the globular clusters, astronomers are taking a second look at “renegade” theories. One such newly fashionable theory, first put forward by Richard Larson in the early 1970’s, argues that the halo of the Milky Way formed over a period of a billion or more years as hundreds of small gas clouds drifted about, collided, lost orbital energy, and finally collapsed into a centrally condensed elliptical system. Larson’s conception of a “lumpy and turbulent” protogalaxy is complemented by computer modeling done in the 1970’s by mathematician Alan Toomre, which suggests that closely interacting spiral galaxies could lose enough orbital energy to merge into a single galaxy.

The passage is primarily concerned with discussing

a)
the importance of determining the age of globular clusters in assessing when the Milky Way galaxy was formed
b)
recent changes in the procedures used by astronomers to study the formation of the Milky Way galaxy
c)
current disputes among astronomers regarding the size and form of the Milky Way galaxy
d)
the effect of new discoveries regarding globular clusters on theories about the formation of the Milky Way galaxy
e)
the origin, nature, and significance of groups of stars known as globular clusters

View answer

The movement for women’s rights traces its origin to the first half of the nineteenth century. The Seneca Falls Convention, held in Seneca Falls, New York in July of 1848, is commonly regarded as the beginning of the women’s rights movement in the United States. This conference was preceded by a series of ground-breaking events that made possible this seminal milestone in the history of American women.The idea for the convention emerged during the 1840 World Anti-Slavery Convention in London, a conference that precluded its female delegates from participation in discussions. Lucretia Mott, a famous women’s rights activist, wrote in her diary that calling the 1840 convention a “world” convention “was a mere poetical license.” She had accompanied her husband to London but had to sit behind a partition with other women activists, including Elizabeth Cady Stanton, who later became one of the main forces behind the Seneca Falls Convention.During the early 1840s, Elizabeth Cady Stanton composed the Declaration of Sentiments, a document modeled after the Declaration of Independence, declaring the rights of women. At the time of its composition, the Declaration of Sentiments was so bold that when Elizabeth Stanton showed the draft to her husband, he stated that if she read it at the Seneca Falls Convention, he would have to leave town. The Declaration contained several new resolutions. It proclaimed that all men and women are born equal and stated that no man could withhold a woman’s rights, take her property, or preclude her from the right to vote. This Declaration also became the foundation for the Seneca Falls Convention.On July 19-20, 1848, the Seneca Falls Convention brought together 240 delegates between ages 22 and 60, including forty men, who spent the two days at the conference debating, refining and voting on the Declaration of Sentiments. Most of the declaration’s resolutions received unanimous support and were officially endorsed. Later in 1848, the Seneca Falls convention was followed by an even larger meeting in Rochester, New York. Thereafter, national women’s conventions were held annually, contributing to the growing momentum in the movement for women’s rights.Q.Which of the following can be most reasonably inferred from the passage?

Larson’s conception of a “lumpy and turbulent” protogalaxy is complemented by computer modeling done in the 1970’s by mathematician Alan Toomre, which suggests that closely interacting spiral galaxies could lose enough orbital energy to merge into a single galaxy.The passage is primarily concerned with discussinga)the importance of determining the age of globular clusters in assessing when the Milky Way galaxy was formedb)recent changes in the procedures used by astronomers to study the formation of the Milky Way galaxyc)current disputes among astronomers regarding the size and form of the Milky Way galaxyd)the effect of new discoveries regarding globular clusters on theories about the formation of the Milky Way galaxye)the origin, nature, and significance of groups of stars known as globular clustersCorrect answer is option 'D'. Can you explain this answer? has been provided alongside types of New observations about the age of some globular clusters in our Milky Way galaxy have cast doubt on a long-held theory about how the galaxy was formed. The Milky Way contains about 125 globular clusters (compact groups of anywhere from several tens of thousands to perhaps a million stars) distributed in a roughly spherical halo around the galactic nucleus. The stars in these clusters are believed to have been born during the formation of the galaxy, and so may be considered relics of the original galactic nebula, holding vital clues to the way the formation took place.The conventional theory of the formation of the galaxy contends that roughly 12 to 13 billion years ago the Milky Way formed over a relatively short time (about 200 million years) when a spherical cloud of gas collapsed under the pressure of its own gravity into a disc surrounded by a halo. Such a rapid formation of the galaxy would mean that all stars in the halo should be very nearly the same age.However, the astronomer Michael Bolte has found considerable variation in the ages of globular clusters. One of the clusters studied by Bolte is 2 billions years older than most other clusters in the galaxy, while another is 2 billion years younger.
