A gravitational wave detector is an L-shaped interferometer whose two arms, each four kilometres long, are watched for the minute change in length produced when a wave from colliding black holes or neutron stars passes through the Earth.

Their instruments, such as the giant sundial called the Samrat Yantra and the hemispherical Jai Prakash Yantra, measured time, declination and the positions of the planets with shadow and sightline alone, and the Jaipur site was inscribed on the UNESCO World Heritage List in 2010.

At that point the gravitational pulls of the Sun and the Earth combine with the orbital motion so that a spacecraft keeps station with the Earth, and from there the Sun can be watched continuously without any eclipse or occultation.

AstroSat was launched on 28 September 2015 by PSLV-C30 from Sriharikota into a near equatorial low Earth orbit.

In 1977 astronomers watched Uranus pass in front of a distant star from the observatory in the Javadi hills, and the dips in the star's light before and after the planet itself crossed showed that rings surround Uranus.

It is now part of the Indian Institute of Astrophysics, and its digitised archive of daily photographs of the solar disc, sunspots and the chromosphere is among the longest continuous records of the Sun anywhere, which makes it valuable for the study of long solar cycles.

The Indian Astronomical Observatory sits there at about 4,500 metres in a cold desert, one of the highest and driest observing sites in the world, where very little water vapour and almost no artificial light make the sky exceptionally clear and dark.

The telescope was built in collaboration with Belgium and activated in 2016 on the Devasthal ridge at about 2,450 metres, and the same site carries a 1.3 metre fast optical telescope and the four metre liquid mirror telescope.

Fourteen of them stand close together in a central square of about one kilometre, and the remaining sixteen are spread along three arms in a Y shape stretching some twenty-five kilometres, which gives the array both the sensitivity of a filled aperture and the resolution of a wide one.

The array stands at Khodad, near Narayangaon, about eighty kilometres north of Pune, on flat land chosen for its low level of man-made radio interference, and it is operated by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research.

The United States gives every person two citizenships, of the union and of the state of residence, while India deliberately gives one citizenship for the whole country, so that no state may treat the people of another state as outsiders.

The Weimar constitution allowed the President to suspend civil liberties in an emergency, and the Indian provisions under which the operation of certain Fundamental Rights may be restricted during a proclamation of emergency follow that model.

The Australian constitution has a list of subjects on which both the federal and the state legislatures may make law, and India adopted the device as the Concurrent List in the Seventh Schedule, with central law prevailing in case of conflict.

Two features are traced to the South African constitution: the procedure for amending the Constitution, which combines a special majority with the consent of States for some provisions, and the election of members of the Rajya Sabha by the elected members of the State legislative assemblies through proportional representation by…

India had no such chapter at first; ten Fundamental Duties were added in 1976 by the Forty-second Amendment on the recommendation of the Swaran Singh Committee, and an eleventh, the duty of a parent to provide education to a child, was added later.
