About Program







This is part of its efforts to popularize science to the General Public and Students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time. Hence, to fill the gap between what students are acquiring through the curriculum and what it is required, TNSF is planning its activities on higher science to students who are pursuing higher education


The Nobel Prize in Physics 2019 was awarded "for contributions to our understanding of the evolution of the universe and Earth's place in the cosmos" with one half to James Peebles "for theoretical discoveries in physical cosmology", the other half jointly to Michel Mayor and Didier Queloz "for the discovery of an exoplanet orbiting a solar-type star."



The search for Extra-solar planets (popularly known as Exoplanets) was professionally initiated by Captain William Stephen Jacob, the then director of Madras Observatory in 1855 and finally Michel Mayor and Didier Queloz of Geneva Observatory discovered the first confirmed planets outside the Solar system for which they are awarded the Nobel Prize. We shall also describe that the ultimate aim of this field is to answer if life exists beyond the Earth and the current status towards achieving an answer to the eternal curiosity of mankind "Are we alone?"

புறக்கோள் (extrasolar planet, அல்லது exoplanet), என்பது சூரியக் குடும்பத்திற்கு வெளியே உள்ள ஒரு கோளைக் குறிக்கும். 1 நவம்பர் 2019 நிலவரப்படி, 3,067 சூரிய குடும்பங்களில் 4,126 உறுதிப்படுத்தப்பட்ட எக்ஸோபிளானெட்டுகள் உள்ளன, 671 அமைப்புகள் ஒன்றுக்கு மேற்பட்ட கிரகங்களைக் கொண்டுள்ளன. இவற்றில் பெரும்பாலான புறக்கோள்களின் புகைப்படங்கள் நேரடியாகப் பெறப்படாமல், ஆரத் திசைவேகம் (radial velocity) அவதானிப்புகள் மூலம் பெறப்பட்டவையாகும்.
பல புறக்கோள்கள் வியாழன் கோளை ஒத்த பெரும் கோள்கள் ஆகும். சில புறக்கோள்கள் எடை குறைந்தவையாகும். இவை பூமியை விட சில மடங்கு அதிக நிறை உடையவை பல விண்மீன்கள் கோள்களைக் கொண்டுள்ளதென இப்போது உறுதிப்படுத்தப்பட்டுள்ளது. கிட்டத்தட்ட 10 விழுக்காடு விண்மீன்கள் சூரியனை ஒத்தவை ஆகும்.
