June 17 , 2026 3 days 135 0
  • Astronomers at the National Centre for Radio Astrophysics discovered five new millisecond pulsars using India's upgraded Giant Metrewave Radio Telescope (uGMRT).
  • The pulsars were discovered in the ancient globular clusters Messier 69 and Messier 70, which are among the oldest and densest star systems in the Milky Way.
  • Millisecond pulsars are rapidly rotating neutron stars that spin within a few milliseconds and usually form in binary star systems.
  • Two pulsars were discovered in Messier 69 and three in Messier 70, marking the first-ever detection of pulsars in both clusters.
  • One pulsar, M69A, was found orbiting a companion star, likely a white dwarf, completing one orbit every few days.
