The Samrat Yantra (giant sundial) at the Jaipur Observatory
Welcome to the new jantarmantar.org!
The redesigned website was launched in October 2015 - and we are still hard at work refining the content and tweaking the design. As new pages and features are added, they will be announced through our Facebook and Instagram pages, so follow us there!
New to jantarmantar.org is the Learn section, featuring a wealth of information about the observatories and the unique instruments Jai Singh created to observe celestial objects.
But more than that, the Learn section also features projects you can do to learn more about the observatories and sky observation without a telescope.
The Tours section features all new panoramic virtual tours that work on desktops, laptops, and mobile devices!
And the Gallery will be presenting curated collections of photographs, panoramas, 3D models, and animations in a portfolio format.
New this month!
We’ve added a project to the Learn section that features panoramas customized to work with the free open source planetarium software Stellarium. Now you can view the night sky from the Jantar Mantar!
