DAY 7 (3/4): MAHARAJA’S ASTRONOMICAL LEGACY, Jantar Mantar, Jaipur, Rajasthan, India, 2018.11.30

In 2010, Jaipur’s astronomical experiment ground, Jantar Mantar, with what many referred as the “world’s largest sundial” was inscribed in UNESCO World Heritage.   The world’s largest sundial Vrihat Samrat Yantra was said to provide time with an accuracy of 2 seconds.  Built by Maharaja Sawai Jai Singh II in 1734 as one of the five Jantar Mantars (Delhi, Jaipur, Varanasi, Ujjain, Mathura) in India, Jaipur’s Jantar Mantar was used to observe the movement of the sun, moon and planets, and compile astronomical tables.

We are no astronomical experts, but were curious to check out the 18th century observatory.  Even without any astronomical knowledge, the splendid instruments can be appreciated purely for their physical beauty and historic values.  From Amber Fort, it took us a while to bargain with different tuk tuk driver to take us back with the same price that we paid in the morning.  In Jaipur, we get off at the entrance of Jantar Mantar, directly across the street from the City Palace.

IMG_0825The moment we entered the compound, we were immediately overwhelmed by the sight of the huge sundial, Vrihat Samrat Yantra.

DSC_2065Right by the entrance, we started from something much smaller, the Unnatamsa Yantra, an instrument to measure the altitude of celestial bodies.

DSC_2071After several smaller instruments, we arrived at the biggest of them all, the Vrihat Samrat Yantra.

DSC_2083With 27m (88 ft) in height, Vrihat Samrat Yantra literally means the “king of all instruments”.

DSC_2094Its shadow moves visibly 1mm per second.  Its face is angled at 27 degrees, the latitude of Jaipur.

DSC_2099Rashi Valaya Yantra is comprised of twelve gnomon dial to measure ecliptic coordinates of stars and planets.

DSC_2101They were also used to measure the coordinates of the 12 constellations.

IMG_0857A small piece of artwork indicates the corresponding constellation.

DSC_2067All instruments were made of stone and marble, with astronomical scale marked on a marble lining.

DSC_2117It must be delightful to witness the gentle movement of shadows across the astronomical scale.

IMG_0858Planet study was also a popular subject at Jantar Mantar.

IMG_0862The last instrument we encountered was Jai Prakash Yantra.

DSC_2105Jai Prakash Yantra is consisted of two bowl shaped marble slabs with inverted map of the sky.  it allows astronomers to move inside the slab to measure altitudes, azimuths, hour angles of celestial bodies.

IMG_0871The nearby Kapali Yantra is also consited of two sunken bowls with a map of the heaven carved on the bowl.

DAY 54 (2 OF 2) – PARANAL OBSERVATORY, ATACAMA DESERT, CHILE

Directed by Patricio Guzman, documentary Nostalgia de la Luz (Nostalgia for the Light) introduced us to the Very Large Telescope at Paranal in the Atacama Desert a few years ago.  In the film, Guzman on one hand depicts how scientists at Paranal Observatory search for the origin of the universe by looking up to the sky, and on the other hand, how a group of local women search for the remains of their loved ones who were executed under the Pinochet’s regime by looking down into the gravel of the Atacama desert near the Paranal Observatory.  Owned by European Southern Observatory (ESO), Paranal Observatory contains the most advanced telescopes in the world, allowing scientists to obtain HD images of the universe, and study in details the black hole at the very centre of our Milky Way Galaxy.  Name the Very Large Telescope (VLT), the four telescopes at Paranal are the biggest optical telescopes in the world, each with a lens of 8.2m in diameter.  Situated at 2600m above sea level atop Cerro Paranal, the thin air and dry weather allow scientists at Paranal to observe the night sky almost every night of the year.
From online research, we were glad to find out that the ESO offers free-guided tours of the Paranal Observatory every Saturday.  All we needed to consider was to find our own transportation to get there.  With a hired car from Antofagasta, we were able to reach the observatory half an hour before our appointment at 10:00.  Located 120km south of Antofagasta, the journey took us about 2 hours of driving in the Atacama Desert.  The drive was pleasant in early morning.  By the time we stepped out of the car at Paranal, we could immediately feel the heat and strong UV of the sun.  The tour lasted for about 2.5 hours.  We were led by the guide to visit the visitor centre, the interior of one of the four Very Large Telescopes, the central control centre, and the residence for the scientists and engineers.  The guide, who was an astronomer, explained to us in details about the functioning and maintenance of the telescopes.  Inside the telescope, we were fortunate to watch the engineer to test the rotation of the telescope.  The control centre was quite empty while we were there, because most of the staff was asleep in the residence during the day.  Winning numerous design awards a few years ago, the residence building was also interesting to check out.  Inside the building, the swimming pool and greenhouse create a desert oasis in the Atacama.  The building was also featured in one of the James Bond movie a few years ago.
The inspiring visit to the Paranal was definitely a highlight of our journey.  It further opened up our curiosity about the universe and the night sky.  This experience also concluded our journey in the Atacama, and to a larger extent, the Andean highlands of Bolivia, Northern Argentina and Chile.  Tomorrow, we would arrive at Chiloe Island in the Lake District, some 2,100km south of Antofagasta, where Martian landscapes would give way to Alpine scenery.

DAY 30 (2 OF 2) – STARRY NIGHT, SAMAIPATA, BOLIVIA

Accompanied by the sound of cicadas, the light of fireflies, and the faint shadows of agave plants, seeing the southern sky at a clear spring night in Samaipata was a real treat for us.
