Scientists from top government institution (Indian Institute of Astrophysics in Bengaluru) have designed a special mirror- and lens-based apparatus.
It will ensure that every Ram Navami Day at noon, there is a ray of sunlight that falls directly on the forehead of the 'achal Ram Lalla' idol at Ayodhya.
It is officially called the 'Surya Tilak mechanism'.
The Surya Tilak mechanism would be fully operational when the full temple is constructed.
