Want to build your own telescope? Attend this session..

AASTRO Thiruvananthapuram will have its next monthly public lecture session on 2nd June 2011, 5.30 pm at Kerala State Science and Technology Museum and Planetarium, PMG, Thiruvananthapuram. The session will be handled by Mr K P Prabhakaran, who is an expert in home-made telescopes. He will present a demonstration and sky watching session with the aid of his own telescope. There is a common belief that a good quality telescope is a highly expensive one and not everyone can access it. Mr. Prabhakaran wish to convey the point that a good telescope is reachable to anyone without much expense.

Any interested person is welcome to the session. For details, feel free to call +91 9846608238

AASTRO May Session On Stellarium

 

 

The monthly public lecture session of May 2011 was held on 5th May, 5.30 pm at our usual venue of Priyadarshini Planetarium, PMG, Thiruvananthapuram. This time it was a presentation and demonstration on how to utilize Stellarium software for an effective sky watching. The session was handled by Mr.Vaisakhan Thampi and he pointed out  the key features of the software and the ways in which they can be utilized effectively. Students, teachers and other interested public were present.

Stellarium is an open source software, which can be downloaded installed, modified and redistributed by anyone. It renders a realistic sky visible from any part of the world at any instant of time, showing more than 600000 stars, respective constellation lines in 12 different cultures, their labels and even constellation art. It incorporates planets and their satellites with a very good zoom capacity. One can download Stellarium from here and its absolutely free !!

AASTRO outreach flavoured kid’s vacation camp @ Thiruvananthapuram

Around 90 kids were there with us when they enjoyed combining patches of clear night sky with patterns from the Stellarium software at Thiruvananthapuram last week.Vyloppilli Samskrithi Bhavan organised a vacation camp for students called Maampazhakkaalam 2011' .Last Thursday night,AASTRO people took them for a session exploring wonders of the night sky and digest a little astronomy.At the Planetarium open air theatre,Pappootty mash introduced basic astronomy to kids.Concepts of raashi, janmanaal etc were explained.Students were curious about all those and the excitement summited when they had a session on Stellarium.Shri.Vaisakhan Thampi and Shri.Kiran Mohan made a presentation comparing the available clear night sky with Stellarium.

Discussion on Model of the Universe-How it is…

In our April meet up,Mr. B. Saharsh shared his ideas about a new model of universe,how the boundary of universe can be and so on.An effective discussion concluded that our present knowledge may not be sufficient to understand the actual structure of universe.AASTRO members,teachers, students and astronomy enthusiasts participated actively.
AASTRO will conduct monthly public talks on every first Thursday.The topic will range from astrophotography to history of astronomy.These lectures are open to public and delivered by subject experts and enthusiasts in different disciplines.so far we organised more than 15 talks

Vishu – The Astronomical New Year

First of all, Happy Vishu to all....Lets talk some astronomy on this eve.... We all know that from Earth, Sun would appear to revolve around us. The ancient people believed Sun actually is revolving around Earth in a circular orbit. To locate sun in its orbit, they divided the 'solar orbit' around Earth, called the ecliptic, into twelve equal parts. To identify these parts in sky, they joined some of the stars in that portion of sky to make out a picture. Then they named each part according to the picture they made out in that portion. These twelve parts of sky on the sun's path around earth are called the twelve Raashi's(രാശികള്‍), named Medam, Idavam, Midhunam etc. The strip of sky around Earth that comprises of these twelve raashis is called the Zodiac(രാശിചക്രം). See the picture below:

 

 

As Sun takes 365 days to make a complete revolution, it is trivial to see that it spends around 30 days (365 days/12) in a particular Raashi. Our Malayalam calendar is based on this concept. That is, our Medamaasam(മേടമാസം) is that period of the year during which Sun is in Medam raashi. The day on which Sun moves from one raashi to another is called Sankraanthi(സംക്രാന്തി).
Vishu is astronomically the Medasankraanthi(മേട സംക്രാന്തി), that is, the day on which Sun enters Medam raashi. Historically, Medam 1 is the beginning of Malayalam calendar. But most of us consider Chingam 1 as New Year which is the beginning of Kollavarsham(കൊല്ലവര്‍ഷം). This is believed to be started by the King of Kollam (Venad Udaya Marthanda Varma) who thought Chingam, the season of harvest, can be the beginning of a new year. Chingam has no astronomical significance. More on this topic can be found here , an interesting blogg by Vaishakhan Thampi,AASTRO office bearer and a research fellow in Physics  from NIIST,Trivandrum

This is how AASTRO debunked the ‘Super Moon Hoax’

There were widely spread rumors and  fear among the people over chances of natural disasters and occurrence of unusual phenomenon because of  'Super Moon effect'  these days.Speculations have moved the goalposts to within 1 or 2 weeks of a supermoon to suggest a causal relationship with specific natural disasters such as the 2011 Tōhoku earthquake and tsunami. Such a widening of the effect window is unjustified since the Moon was further from the Earth than average, making a super moon effect impossible.

A supermoon is bigger and brighter than an ordinary full moon. The reason: the moon’s orbit around the Earth is elliptical, not round. And so when the elliptical path passes closest to Earth a full moon becomes 14 per cent wider and 30 per cent brighter than an average full moon. Not since 1992 has the moon passed as close to Earth as happened on Saturday night.

AASTRO Kerala took effective efforts  and organised activities at various levels to debunk this controversy.AASTRO Kozhikkode chapter organised classes and demonstration sessions thorough out the district.hundereds of people gathered to take in their fill of the ‘supermoon' that rose on Saturday night sky.Observations were arranged in places like Eranjikkal, Mananchira, Thondayadu, Mukkam, Balussery, Nadakkavu, Perambra,Madappally,Kuttikkaattoor,Kundamangalam and so on.Programmes were organised in different educational institutions too.

Through out the state,AASTRO organised moon watching sessions to strike out the 'hoax'.On cyberspace,AASTRO posted many articles and links over internet to make the science behind super moon clear.One of them can be found here : http://aastro.org/2011/03/super-moon/

Some studies have reported a weak correlation between lunar activity and shallow, very low intensity earthquakes. However, no evidence has been found of any correlation with major earthquakes.The 2011 Tōhoku earthquake and tsunami is the only earthquake of 8.0 magnitude or greater to have occurred within 2 weeks of the 14 extreme supermoons from 1900 to the present date,suggesting that the claim of a supermoon effect on the incidence of large-scale earthquakes is unjustified.
