Indian Institute of Astrophysics                 भारतीय खगोलभौतिकी संस्थान The official page of the Indian Institute of Astrophysics (IIA), located in Koramangala, Bengaluru. A 1.3 m telescope named after Prof. J. C.

The Indian Institute of Astrophysics traces its origin to William Petrie, an enlightened officer of the East India Company, who in 1786 began observations of the meridian transit of stars from Madras, mainly for maritime purposes. This in a short period of ten years, blossomed into the Madras Observatory. The Madras Observatory, especially under the leadership of N.R. Pogson, made tremendous progr

ess, diversifying its focus to the astronomical studies of planets, asteroids, the sun, solar eclipses and variable stars. Teams from the Observatory were among the first to observe the Helium line at the solar eclipse in 1868, visible from Guntur in South India. Around the end of the 19th century, the Madras Observatory was shifted to Kodaikanal. The Kodaikanal Observatory became famous in
its own right with pioneering contributions such
as the Evershed Effect discovered in 1909. The
work at Kodaikanal continues without any break
even today and the observatory holds an archive of spectroheliograms which are recorded daily. In 1971, the organization became an autonomous academic institution devoted to astronomy, astrophysics and allied topics, under the directorship of Professor M.K.Vainu Bappu. It is now a premier Institute in the country specialized in Astrophysics and it is fully funded by the Department of Science and Technology, Government of India. Several new major facilities have been added
during the last four and half decades. They include: the 2.34 m Vainu Bappu Telescope (VBT) at Kavalur, the 2-m Himalayan Chandra Telescope (HCT) at Hanle and the Radio Heliograph at Gauribidanur. Recent initiatives at Hanle include: commissioning of a High Altitude Gamma Ray (HAGAR) telescope array and setting up of a Major Atmospheric Cerenkov Experiment (MACE) telescope by BARC jointly with TIFR and IIA. Bhattacharyya was installed at Kavalur and commissioned in 2014. The Ultra-Violet Imaging Telescope (UVIT) system, developed by the Institute jointly with national laboratories, was calibrated in a specially established facility, the M.G.K.Menon Laboratory, at the Institute’s campus in Hosakote. The system is
integrated on to the ASTROSAT satellite which is put into the orbit by ISRO on 28 September, 2015.

भारतीय ताराभौतिकी संस्थान देश का एक प्रमुख संस्थान है, जो खगोल ताराभौतिकी एवं संबंधित भौतिकी में शोधकार्य को समर्पित है। इसका उद्गम मद्रास (चेन्नै) में 1786 में स्थापित की गई एक निजी वेधशाला से जुड़ा है, जो वर्ष 1792 में नुंगम्बाकम में मद्रास वेधशाला के रूप में कार्यशील हुई। वर्ष 1899 में इस वेधशाला को कोडैकनाल में स्थानांतरित किया गया। 1971 में कोडैकनाल वेधशाला ने एक स्वायत्त संस्था भारतीय ताराभौतिकी संस्थान का रूप ले लिया। संस्थान का मुख्यालय कोरमंगला, बेंगलूर में अपने नए परिसर में वर्ष 1975 में स्थानांतरित हो गया। विज्ञान एवं प्रौद्योगिकी विभाग के अवलंब से संचालित यह संस्थान आज देश में खगोल एवं भौतिकी में शोध एवं शिक्षा का एक प्रमुख केन्द्र बन गया है। संस्थान की प्रमुख प्रेक्षण सुविधायें कोडैकनाल, कावलूर, गौरीबिदनूर एवं हान्ले में स्थापित हैं।
एक शताब्दी से भी अधिक समय से कोडैकनाल वेधशाला प्रेक्षणात्मक सौर एवं वायुमंडलीय भौतिकी में सक्रियता का मुख्य केन्द्र रही है। कावलूर स्थित वेणुबप्पू वेधशाला 1960 के दशक से रात्रिकालीन खगोल की मुख्य प्रकाशिक वेधशाला रही है। यहां अनेक दूरदर्शी कार्यशील हैं जिनमें प्रमुख हैं - 2.34 मीटर वेणुबप्पू दूरदर्शी। गौरीबिदनूर रेडियो वेधशाला में एक डेकामीटर तरंग रेडियो दूरदर्शी विन्यास एवं रेडियो होलियोग्राफ स्थापित है।
दक्षिण पूर्व लद्दाख के हान्ले नामक स्थान में स्थापित की गई नई उच्च उत्तुंग भारतीय खगोल वेधशाला ने संस्थान की रात्रिकालीन खगोल संबंधी सुविधाओं में वृद्धि की है। यहां वर्ष 2001 से 2 मीटर व्यास का हिमालयन चंद्रा दूरदर्शी कार्यरत है। सात इकाइयों वाला एक उत्तुंग गामा किरण दूरदर्शी भी हान्ले में हाल ही में स्थापित किया गया है।
बेंगलूर परिसर में एक विशाल पुस्तकालय, संगणक केन्द्र, भौतिकी एवं इलेक्ट्रॉनिकी प्रयोगशालायें, प्रकाशिकी तथा यांत्रिक कार्यशालायें विद्यमान हैं जो संस्थान के सक्रिय उपकरण विकास कार्यक्रम को ठोस अवलंब देती है।

The Hon'ble Minister of State (Independent Charge) of the Ministry of Science and Technology, Government of India, Dr. Jitendra Singh, visited the Indian Institute of Astrophysics on 28th April to lay the foundation stone of the "MKV Bappu Bhavana" building at the Institute’s campus in Bengaluru. The foundation stone was laid in the presence of Dr. S. Somanath, Chairperson of the Governing Council of IIA & Former Secretary of the Department of Space, and other dignitaries.

The new building will be aptly named in honour of Prof. Manali Kallat Vainu Bappu, the founding Director of IIA and a pioneer of modern Indian optical astronomy. Prof. Bappu served as the Director of IIA until 1982 and was President of the International Astronomical Union, as well as a recipient of the Padma Bhushan.

The Hon’ble Minister also inaugurated the Aspheric Grinder & Polisher at the Optics Lab, inspected the mirror roundels and Segment Support Assemblies for the Thirty Meter Telescope project, following which, he visited the Payload Operations Centre (POC) which receives data from the UltraViolet Imaging Telescope (UVIT) on board AstroSat, and the Visible Emission Line Coronagraph (VELC) on board Aditya-L1.

The Hon'ble Minister and Dr S. Somanath addressed the staff of IIA following a presentation by the Director IIA on the Institute's history, current research, and future projects. These include the National Large Solar Telescope, National Large Optical-IR Telescope, Upgraded Himalayan Chandra Telescope, and COSMOS-2 planetarium.
