ISRO and IIT Guwahati Discover New Challenges in Theories of X-Ray Pulsar

ByNews Polite

Researchers from IIT Guwahati and the Indian Space Research Organisation (ISRO) have made a surprising discovery that could reshape our understanding of X-ray pulsars. They found that the X-rays emitted by Swift J0243.6+6124, the first known Galactic Ultraluminous X-ray Pulsar, exhibit an unexpectedly low level of polarization. This pulsar, which…

Sun’s Magnetic Activity Is Making It Difficult to Gauge Its True Age, Study Finds

ByNews Polite

Astronomers have traditionally relied on helioseismology to estimate the Sun’s age by analysing the vibrations that ripple through its interior. However, recent research has uncovered a significant obstacle, the Sun’s magnetic activity, which follows an 11-year cycle, appears to be distorting these measurements. Data from the Birmingham Solar Oscillations Network…
