    Study Notes

    Mystery Object in Our Galaxy

    • A mysterious entity was discovered in our galaxy, orbiting a pulsar, by the MeerKAT Radio Telescope in South Africa.
    • The unidentified object is circling a pulsar in a star cluster 40,000 light years from Earth.

    Pulsars and Their Beams

    • Pulsars are spinning, dead stars that shoot out powerful beams of light, similar to cosmic lighthouses.
    • These beams can flash by Earth at regular intervals, like a precise clock.

    Detection of the Mystery Object

    • The pulses of a pulsar called PSR J0514−4002E revealed an invisible companion, using the timing of the light flashes to determine its mass.
    • The object's mass is estimated to be 2.1 to 2.7 times the mass of the sun.

    Possible Identity of the Object

    • The object's mass might be too heavy for a neutron star, but too light for a black hole.
    • Scientists suspect that a neutron star collapses to form a black hole at a certain mass, but the exact mass is unknown.

    Future Research

    • Researchers hope to uncover the object's identity by continuing to track the pulsar's flashes.
    • This could provide insight into other similar mysterious objects in space.
