Astronomers Discover Mystery Object in Milky Way More Massive Than Any Known Neutron Star But Lighter Than Smallest Black Hole

Astronomers have discovered a mystery object in the Milky Way that is more massive than any known neutron star but lighter than the smallest black hole.
The dense stellar remnant is orbiting a rapidly spinning neutron star or millisecond pulsar located around 40,000 light-years away within a dense clump of stars called a globular cluster in the Milky Way.
Astronomers Discover Mystery Object in Milky Way More Massive Than Any Known Neutron Star But Lighter Than Smallest Black Hole

Astronomers have discovered a mystery object in the Milky Way that is more massive than any known neutron star but lighter than the smallest black hole. The dense stellar remnant is orbiting a rapidly spinning neutron star or millisecond pulsar located around 40,000 light-years away within a dense clump of stars called a globular cluster in the Milky Way. If it's a black hole, this would make it an incredibly coveted radio pulsar-black hole binary system. The discovery could help scientists better determine where to draw the dividing line between neutron stars and black holes, both born when a massive star dies. A pulsar-black hole system with highly periodic outbursts of the pulsar can be crucial for testing theories of gravity, known as general relativity.

  • Unique Points
    • The object sits in Caldwell 73 (NGC 1851), a globular cluster that may have formed from two clusters that coalesced in a dwarf galaxy. It is half of a binary system, the other half being a pulsar.
    • If it's a neutron star, it may be the heaviest one known to date with lessons for the uncertain physics of extremely dense nuclear matter.
    • Both neutron stars and black holes are venues for some of the universe's most extreme physics. Better understanding their genesis and interactions will help astrophysicists decipher everything from quantum mechanics to the evolution of galaxies.
  • Accuracy
    • If it's a black hole, it may be among the lightest known which could affect understanding of supernova explosions or dynamical interactions such as neutron star mergers inside globular clusters.
  • Deception (30%)
    The article is misleading in several ways. Firstly, the author states that the object has a mass between 2.09 and 2.71 times that of our Sun which implies it could be either a neutron star or black hole but they are not sure which one it is.
    • The article claims that this compact object may be among the smallest known black holes, however according to NASA's Goddard Space Flight Center, the smallest known black hole has a mass of 5.4 times that of our Sun.
  • Fallacies (70%)
    The article contains an appeal to authority fallacy by citing the opinions of experts in the field without providing any evidence or reasoning for their conclusions. The author also uses inflammatory rhetoric when describing the potential implications of this discovery on our understanding of physics and cosmology.
    • ]If a neutron star, it is probably the heaviest one known to date, with lessons for the uncertain physics of extremely dense nuclear matter[
    • It may be the lightest known black hole which could affect our understanding of supernova explosions or dynamical interactions such as neutron star mergers inside globular clusters.
  • Bias (80%)
    The author uses language that implies the object is a mystery and something to be puzzled over. The use of phrases like 'confounding' and 'neither-here-nor-there' creates an air of uncertainty around the topic.

However, this statement is not entirely accurate as it does not take into account other possibilities such as dark matter or an unknown type of compact object. Secondly, the article states that if it's a neutron star then it would be exciting because it could provide new insights in nuclear physics at very high densities. This statement implies that there is no existing knowledge about nuclear physics at these densities which is not true as scientists have been studying this area of research for decades.

This statement implies that there are no existing theories about gravity or compact objects which is not true as scientists have been studying these areas of research for centuries.
