NASA's Hubble Telescope, a project of international cooperation between NASA and the European Space Agency, has recently obtained a new view of an elliptical galaxy that that astronomers believe to have been "puffed up" because of black holes in its core. This galaxy is approximately ten times wider in diameter than the Milky Way and is part of the Abell 2261 cluster. Astronomers believe this galaxy is bloated, because there are two black holes are closely orbiting each other collectively having the mass of billions of suns. A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. The astronomers think that if one of the black holes was native to the galaxy, the second hole would have been added from a smaller galaxy that was gobbled up by the massive galaxy.
This article came from Science Daily, an American news website for scientific articles. The articles are selected from news releases by universities and other research institutions, making this source credible. The context surrounding this text is the newly taken pictures from NASA's Space Hubble Telescope.
Because it is more of a scientific article, there are no detected rhetorical devices found in this article.
This article was written for other scientists, mainly astronomers. The reader can tell this by the jargon used such as "black hole," "galaxy," and "theory of general relativity." The purpose of the article was to explain several theories surrounding the existance of an incredibly large galaxy. I think the author did an okay job of explaining these theories, because even though a fellow astronomer would be able to comprehend what the author was saying, the average reader would have difficulty understanding what the author was talking about. Even though analogies are used such as "Expecting to find a black hole in every galaxy is sort of like expecting to find a pit inside a peach," the article is still very complex.
