Inner coma located on the edges of its nucleus after it entered the comet’s orbit, making observations from ten to eighty km relative to the comet’s center (Feldman et al.Alice detected atomic oxygen and hydrogen emissions initially, which was dependent on the orientation and position of its light slit relative to the comet’s nucleus, finding that the emissions were localized around the comet’s nucleus and highly concentrated around the comet’s neck (Feldman et al. This concentration around the comet’s neck was particularly observed around its northern latitudes. Subsequently, Alice also detected weaker atomic CO2 and carbon emissions. By analyzing the resulting relative line intensities, the study found that emissions of hydrogen and oxygen were due to dissociation of water molecules by photoelectrons. Moreover, they also found that dissociation of CO2 to the observed carbon atoms was the result of dissociation by electrons. Finally, the relative brightness of carbon atoms to hydrogen atoms observed by Alice was attributed to the variations in water and CO2 abundance within the nebulous envelope around the comet’s nucleus (Feldman et al.However, despite the media article and the scholarly article reporting on the same study and its results, they differ in terms of how they are structured or formatted. The media article is not divided into sections like the scholarly article, instead providing a short concise summary of the latter’s aims and results. The media article presents information on the scholarly article in continuous prose, integrating the results findings with its own derived conclusions that are compatible with those identified in the scholarly source. In addition, the study’s findings are reported in the first paragraph of the media source, after which it presents important aspects of the study. On the other hand, the scholarly article is structured in the classic research format. This involves an abstract, an introduction, instrument construction, observations, discussion, and conclusion. In addition, the scholarly also has a reference section, similar to the media source, although the former has more references than the latter. Moreover, some of the sections in the scholarly source’s structure are also divided into different subsections, such as the observations section that is divided into three subsections that cover observations during September, October, and November as the spacecraft orbited around the
