  • Indian Scientists Develop New Method to Measure Distances in Deep Space

    Why in the News?

    Indian astronomers, including researchers from IIT Kanpur, have developed a new technique to measure distances in space using pulsars by combining dispersion measure and scatter broadening.

    What are Pulsars?

    • Pulsars are dense, rapidly spinning neutron stars
    • Emit regular radio wave pulses
    • Act as cosmic clocks due to highly stable rotation
    • Used to detect gravitational waves and deep space phenomena

    New Measurement Method

    Scientists combined two effects:

    1. Dispersion Measure (DM)

    • Radio waves pass through ionised gas
    • Lower frequency waves arrive later
    • Used to estimate distance

    2. Scatter Broadening

    • Plasma irregularities scatter signals
    • Signals follow multiple paths
    • Causes signal stretching

    New Approach

    • Combined Dispersion + Scattering
    • Improves accuracy of distance measurement

    Study Details

    • Observed 10 pulsars
    • Region studied: Gum Nebula
    • Found Vela Pulsar located behind nebula
    • Developed improved electron distribution model

    Significance

    • More accurate deep space distance measurement
    • No strict distance limitation
    • Can be used for Fast Radio Bursts (FRBs)
    • Improves understanding of interstellar medium
    [2023] Consider the following pairs: Objects in space : Description
