Aryabhatta Research Institute of Observational Sciences
ARIES is an autonomous research institute under the Department of Science and Technology, Govt. of India, specializing in Observational Astronomy & Astrophysics, and Atmospheric Sciences. It was established on April 20, 1954, and moved to its present location on Manora Peak at an altitude of 1951m i n 1961. Its unique longitude (79° East) is critical for observing astronomical events not visible from other major global observatories. ARIES hosts powerful telescopes like the 104cm Sampurnanand Telescope and its Devasthal campus has the 3.6m Devasthal Optical Telescope for cutting-edge research. The institute is vital for studying star clusters, gamma-ray bursts, and atmospheric phenomena.

Himalayan Panorama:The broad, unobstructed view from Manora Peak of the Himalayan range, including peaks like Nanda Devi, Trishul, and Nanda Kot on a clear day, is a mandatory photo opportunity.
Forested Pathways:The serene, winding roads and pathways within the ARIES campus, framed by tall pine and oak trees, provide picturesque landscape photography.
Star Trails Photography:For serious astrophotographers with a prior night-viewing appointment, the clear skies are ideal for capturing star trails or deep-sky objects through personal equipment.Photo Gallery

Its lo...Scientific Prowess and Location Advantage:ARIES is famous for being one of India's foremost institutions in astronomical research, making significant contributions to the field, including the first successful Indian optical observations of Gamma-Ray Burst afterglows. Its location on Manora Peak offers remarkably clear, dark skies for observation, giving it a crucial advantage in the global network of observatories to capture time-critical phenomena.
Key Telescopes:The presence of the Sampurnanand Telescope and its connection to the modern Devasthal Optical Telescope are major highlights.
Stellar Discoveries:It has been instrumental in discovering new ring systems around planets like Saturn and Uranus in the past. -
Architecture:

Dome Dime...Research Infrastructure & Dome Design:ARIES is a complex of specialized scientific buildings, not traditional architecture. The primary architecture is functional, consisting of office blocks, residential quarters, and telescope domes.
Dome Dimensions:The 104cm Sampurnanand Telescope is housed in a large, white, cylindrical dome structure on Manora Peak, designed to open fully for observation and protect the sensitive equipment from weather and dust. The dome's rotating mechanism and sliding shutter system are precision-engineered. Other smaller telescopes, like the solar telescope, are housed in similar but smaller domes. The design prioritizes stable platforms and minimal thermal interference, essential for accurate astronomical observation.
Site Features:The campus is spread over 32. 38 hectares and utilizes reinforced concrete and steel for stability. -

By Train:The nearest major railway station is Kathgodam Railway Station (KGM), about 35 KMS away. Taxis, shared taxis, and buses are easily available from the station to reach Nainital. From Nainital, a local taxi is needed for the final 9 KMS ascent to ARIES.
By Road:ARIES is well-connected by motorable roads. From Nainital city center, take the road towards Manora Peak. It is about a 9 KMS drive, which takes approximately 30-45 minutes depending on traffic and road conditions. The road is steep and winding.
By Local Transport:The only viable local transport option from Nainital Mall Road is hiring a local taxi (like a Kumaon Taxi Union cab) for a dedicated round trip to the peak, as cycle-rickshaws or auto-rickshaws do not go up the steep hill. -

Ideal Part of the Day:Daytime visits are best during the designated afternoon hours (2:00 PM - 4:30 PM) on a weekday. The Evening/Night is the absolute best time for the core astronomical experience, but only with a prior appointment and clear weather. The early morning provides the best mountain view photography. -

Packing:Carry warm clothes even in summer, as the hilltop can be chilly, especially after sunset. A high-powered camera is a must for the panoramic views.
Accommodation:Stay in Mallital or Tallital in Nainital and book a round-trip taxi, as accommodation is not available on the restricted ARIES campus.
Other Topics:
Mandatory Booking:An absolute must is a prior written appointment from the ARIES Director's office for the night sky viewing or even the day visit; spontaneous visits are usually denied.
