Indian Observatories and Astronomy

The Square Kilometer Array (SKA) is a radio telescope located in Australia and South Africa. It is the largest and most ambitious radio telescope ever built, consisting of thousands of individual antennas spread across multiple locations.

The cosmic microwave background was discovered in 1965 using the Cosmic Background Explorer (COBE) satellite.

The first pulsars were discovered in 1967 using the Arecibo Observatory.

Optical observatories use telescopes to collect and focus light from celestial objects, allowing astronomers to study their positions, motions, and other properties.

X-ray observatories are equipped with instruments that can detect and analyze X-rays emitted by celestial objects, allowing astronomers to study high-energy phenomena such as black holes, neutron stars, and supernova remnants.

Radio observatories are commonly used to study the properties of interstellar gas and dust, as radio waves can penetrate these regions and provide information about their composition and structure.
