  • The NASA researchers have found high energy particles erupting from ice in the Antarctic region.
  • The researchers believe that these particles are proof to parallel universe.
  • The ANTIA detect radio pulses that are being emitted by Antarctic ice sheet.
  • The neutrinos in the ice produce radio pulses due to Askaryan effect.
  • Askaryan effect is the phenomenon where a particle travelling at a velocity faster than light in a dense electric medium.
  • It is the first NASA observatory of neutrinos.
  • Neutrinos are the only particle that reaches the earth unattenuated.
  • Neutrinos are high-energy particles that pose no threat to us and pass through most solid objects without anyone even noticing.
  • Neutrinos constantly bombard Earth and 100 trillion neutrinos pass through our body every second.
  • Rarely do they interact with matter. 
  • But if they do smash into an atom, they produce a shower of secondary particles we can detect.
  • It allows us to probe where they came from in the universe.
