AstroSat

stylish_lining

Recently, the Indian Institute of Astrophysics (IIA) marked the completion of ten years of successful operation of the UltraViolet Imaging Telescope (UVIT) onboard AstroSat. The milestone highlights the long-term scientific contribution of UVIT in ultraviolet astronomy.

About AstroSat

AstroSat is India’s first dedicated space observatory designed to study celestial objects across multiple wavelengths. It observes the universe simultaneously in X-ray, ultraviolet, and limited optical spectral bands, making it a unique mission in Indian space science.

The satellite covers energy bands ranging from 0.3 keV to 100 keV, enabling detailed studies of high-energy astrophysical phenomena.

Key Features of AstroSat

AstroSat enables simultaneous multi-wavelength observations of astronomical sources using a single satellite platform. This capability allows scientists to better understand the physical processes occurring in cosmic objects such as stars, galaxies, and black holes.

Payloads of AstroSat

AstroSat carries five scientific payloads:

  • UltraViolet Imaging Telescope (UVIT)

  • Large Area X-ray Proportional Counter (LAXPC)

  • Cadmium–Zinc–Telluride Imager (CZTI)

  • Soft X-ray Telescope (SXT)

  • Scanning Sky Monitor (SSM)

UltraViolet Imaging Telescope (UVIT)

UVIT consists of two co-aligned telescopes. One telescope observes near-ultraviolet and visible wavelengths, while the other is dedicated to far-ultraviolet observations.

Mission Operations

The satellite is operated from the Mission Operations Complex (MOX) at the ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru. ISRO manages AstroSat throughout its entire mission life.

Objectives of AstroSat

The major scientific objectives of AstroSat include:

  • Understanding high-energy processes in binary star systems containing neutron stars and black holes

  • Estimating the magnetic fields of neutron stars

  • Studying star formation regions and energetic processes in galaxies beyond the Milky Way

  • Detecting new and transient X-ray sources in the sky

  • Conducting deep-field surveys of the universe in the ultraviolet region
