  • Deception (80%)
    The article is deceptive in that it presents a new discovery when the information presented has been known for decades. The author claims to have resolved the debate about what was left behind after Supernova 1987A by stating there are compelling signs of a neutron star hiding in its debris field, but this conclusion has already been reached and accepted by scientists based on previous observations.
    • The author claims to have resolved the debate about what was left behind after Supernova 1987A, but this conclusion has already been reached and accepted by scientists based on previous observations.
    • The article presents new information as if it is the first time that evidence for a neutron star has been found when it was actually discovered decades ago.
  • Fallacies (85%)
    The article contains an appeal to authority by citing the James Webb Space Telescope as a source of information. The author also uses inflammatory rhetoric when describing the discovery as 'super-important' for nuclear physics and particle physics.
    • Bias (85%)
      The author of the article is biased towards a particular conclusion that there was a neutron star left behind in Supernova 1987A. The author uses language such as 'compelling signs' and 'super-important for nuclear physics and particle physics', which suggests they have already reached their own conclusion before presenting any evidence to support it.

                  The article is deceptive in that it presents a single scenario as the definitive answer when there are multiple possibilities. The author also uses sensationalism by describing the discovery of a neutron star as 'a once-in-a-lifetime opportunity to study one in the early stages of its life'. Additionally, they use selective reporting by only mentioning two possible scenarios and not discussing any other theories that may exist.

                  The article contains an appeal to authority fallacy by stating that the James Webb Space Telescope is the most powerful telescope ever built and has already revolutionized our understanding of the universe within its first two years of operation. The author also uses a dichotomous depiction when describing SN 1987A as having created either a neutron star or black hole, but only one possibility can be true. Additionally, there is an inflammatory rhetoric used in stating that the discovery will give astronomers a once-in-a-lifetime opportunity to study one in the early stages of its life.
