Astronomy Camp at AIS 2011

Well, this is the first blog post that I'm publishing after 2 months. I'm really sorry about the absence of updates and news as i was really busy with University academics and AIESEC work. This post is about the Astronomy camp that we conducted for the Asian International School (AIS) last 18th of March

Astronomy Camp - March 2011 at University of Colombo

I'm now gonna blog about an event that we had in our University almost 2 months back. I'm really sorry guys for dragging this such longer due to the busy schedule I've been undergoing last few months due to various reasons. Hope you don't mind me sharing in so late. Anyway here it is...

Watch Total Solar Eclipse 11th July 2010 Live Streaming from EclipseBlog

The most awaited total solar eclipse of the year 2010 is about to take place in less than next 20 hours from now. There have been a lot of groups/ individuals flocked at South Pacific islands and Chilean territories right now waiting for the eclipse to take place.

IYA2009 Commemorative Coins Issued by Many Countries Worldwide

As the title of this post hints, there were lot of countries involved in this worldwide celebration during 2009, which was the 400th anniversary of both the discovery of telescope for astronomical observation by Galileo Galilei and the publication of “Astronomia Nova” by Johannes Kepler. These were the reasons which were prominent in specifying 2009 as the IYA.

A Tribute to Fiami the author of The Lives of Galileo

I have already made a post about Fiami, and his great gift that I received during the Christmas season. I got many great feedback on that and even my friends wanted to read it, as none of them had the comic book with them, So I thought of doing a youtube video featuring Fiami

"Star Quest 09" Won by Mahinda College, Galle | IYA 2009

Star Quest 09 Won by Mahinda College, Galle | IYA 2009
The second stage of the "Star Quest 09" islandwide Annual Astronomy Quiz Competition concluded today evening at the V.K. Samaranayake Auditorium, University of Colombo, Sri Lanka. After the hot & astounding Grand Finals, Mahinda College, Galle emerged Champions, grabbing the elegant trophy of "Star Quest 09"

Today the Quarter finals, started at 11.00 am with the participation of 8 schools, that qualified for the further competition, at the end of the 1st Stage of "Star Quest 09", held on last 24th.

The Quarter Finalists of "Star Quest 09"

  1. Ananda College, Colombo 10.
  2. Mahinda College, Galle
  3. De Mazenod College, Kandana.
  4. Sirimavo Bandaranayake Vidyalaya, Colombo.
  5. Devi Balika Vidyalaya, Colombo.
  6. Visaka Vidyalaya, Colombo.
  7. Royal College, Colombo.
  8. Nalanda College, Colombo 10.
There was a noticeable interest from the zealous students, all of whom wanted to go ahead in the contest. However the following 4 schools qualified for the Semi Finals, making the selection of winners, narrower.

The Semi Finalists of "Star Quest 09"

  1. Ananda College, Colombo 10.
  2. Mahinda College, Galle
  3. Sirimavo Bandaranayake Vidyalaya, Colombo.
  4. Devi Balika Vidyalaya, Colombo.
In the first session of the Semi Finals Ananda College, and Sirimavo Bandaranayake Vidyalaya were onstage, for the contest. Each team had 4 members and each school had to face three interactive rounds of questions, which were interrogated by the Miss Monika Madhavi, the president of Mathematical and Astronomical Society of University of Colombo. Then Mahinda College, Galle took on the astronomical team of Devi Balika Vidyalaya, Colombo. Sometimes the audience was so thrilled at the reactions and gestures of the students, who showed off their talents in Astronomy and related advanced sciences, like Cosmology and Astrophysics.

However, as per the marks, scored by each school, Ananda College, Colombo 10, and Mahinda College, Galle had the lead over their opponents.

The Grand Finalists of "Star Quest 09"

As the time passed by, the long-waited encounter arrived in the end. It was the elite Anandians who were taking on mighty Mahindians of Down-South. The grand final consisted of three rounds. First round delivered a separate question for each member of each team. The second round was funnier, as it was the busor round, which took the crowd with great joy and enthusiasm. The last round was a different session, which gave 3 niche-related words for each team for the precisest explanation. Each team had 2-minute time for expressing their idea on the special verbatim. It was astronomically funny to see each team getting together and building up the answer, collectively and the utterance, being expressed be an individual, as per the rules and regulations.

In the end, after an unforgettable quizzical experience in the International Year of Astronomy 2009, Mahinda College, Galle had taken the leading edge and thus were crowned Champions, while the Ananda College, became runners-up.

Then the chief guest, who was the renowned Dr. Chandana Jayaratne, a senior lecturer at University of Colombo, and both the patron and chief treasurer of the Mathematical and Astronomical Society delivered his address. He had been excited to behold such a good competition and said that he would envisage a separate department, arranged for Astronomy, in the long run.

The certificates, medallions and the trophy were awarded by the Dr. Chandana Jayarathne and the quiz-masters of the "Star Quest 09", Mr. Sachith Dissanayake, Mr. Praveen
Janantha and Mr. Lasitha Senarathe, all of whom were alumni of Ananda College, coincidentally.

Further, Miss Susini De Silva, the Secretary of Mathematical and Astronomical Society of University of Colombo, made the vote of thanks, paying tribute to everyone, who contributed to the success of "Star Quest 09", organized by the Mathematical and Astronomical Society of University of Colombo. In terms of sponsorships, Sri Lanka Telecom was the golden sponsor, whereas ACBT, Achievers, National Lottery Board & Sustegen also sponsored
"Star Quest 09", providing financial means for the project. The event came to and end at 02:45 pm local time (05:15 h EDT), Colombo, Sri Lanka.
-----------------------------------------------------------------------------
I , J D Prasanna Deshapriya, the blogger of IYA 2009-Astronomy Sri Lanka was glad to report the event, and at the same time felt sad as I could not give all my readers, a live feed of the event, as just as it was taking place, due to technical and financial difficulties. However, I am looking forward to doing that next time.

Thus, another Sri Lankan contribution towards International Year of Astronomy 2009 | IYA 2009 came to a successful conclusion. Long live IYA 2009 !

Around the World in 80 Telescopes : 100 Hours of Astronomy

Around the World in 80 Telescopes : 100 Hours of Astronomy

How wonderful and amazing it is to observe the sidereal skies from any location that you like real time! "Around the World in 80 Telescopes" was a great webcast that covered the heavens on both hemispheres, providing anyone one Earth, the access to online observation. A paramount endeavor of IYA 2009 Cornerstone Projects, 100 Hours of Astronomy, thus unfolds. The observations were carried out with an integration of telescopes, based on and off the terrestrial territories. The live webcast was available from 100HA channel on Ustream.tv.

Astronomers provided a variety of resourceful presentations from different observatories featuring a wide range of telescopic views. Meantime, observations were in progress to analyze the faraway galaxies, extrasolar planets, earth-like planets and many more. In addition to those there were researches dealing with different wavelengths of light to determine exclusive data.

However the webcast come to an end with a successful conclusion, which fetched a great number of feedback from online community worldwide. A big round of applause should go to the dedicated team behind the scene, who were capable of handling the situatin and leaving us all a beautiful memory of IYA 2009.

Japanese Sand & Flower Festa 2009 themed after Galileo & IYA 2009

Japanese Sand & Flower Festa 2009 in themed after Galileo & IYA 2009

The 22nd Japanese Sand & Flower Festa 2009 in Minamisatsuma was held from May 2 to 6 at Fukiage Beach in Kagoshima Prefecture. The festival has a such a beautiful story that relates how the city was determined to activate with efforts of making gigantic sculptures from the sand of Fukiage beach. The inaugural festival was held back in 1987 and the festival continued to be held annually thereupon. This has also become a major tourist attraction of Japan as there were some 150 thousand visitors to the Fukiage beach during previous episode of the festival, held last year.

Well, one might wonder what this has to do with astronomy and IYA 2009. What does something like that has do with an astronomy and IYA 2009 blog.

Yes, there's indeed a lot, to be precise. As this year's festival has been themed after Galileo Galilei and IYA 2009, there's a lot indeed to talk about IYA 2009 happenings of Japan as well.

However this contribution too will generate a lot of new experience to anyone involved in "Sand & Flower Festa 2009". Plus this has been declared an official event if IYA 2009.

Seiichi Sakamoto, one of JAXA's (Japanese Aerospace Exploration Agency) bloggers on the Cosmic Diary was invited to deliver a speech as a delegate of the IYA 2009 Japan Committee and JAXA at the event.

The number of stamps, published for IYA 2009 is fast growing at the moment. A lot of countries and states have already published many valuable and beautiful stamps for International Year of Astronomy 2009. However I though of publishing this new set of stamps that I came acr0ss in the blogosphere, despite my previous post on stamps at http://iya2009sl.blogspot.com/2009/04/iya-2009-official-stamps-issued.html on the very IYA 2009 stamps. But before begin, give a warm round of applause for Galileo Galilei, the fundamental figure behind the IYA 2009.

Long Live Galileo!

IYA Coins Issued by Australia

I just thought of making available some information on IYA coins, that have been issued by Australia back in 2008, as they have not received some reputation. This post will give you some idea of those coins.

IYA 2009 Coins issued ny Australia

In fact two coins were launched by Australian Royal Mint on 7th November 2008, as an effort to highlight IYA 2009 events, which were coming alongside the International Year of Astronomy, in collaboration with the 400th anniversary of Galileo's telescope.

Janine Murphy, Chief Executive Officer of the Royal Australian Mint was quoted saying "In 2009 the world celebrates the exploration of our universe. It marks the 400th anniversary of Galileo Galilei’s first use of the telescope and recognizes his revolutionary discoveries that began modern astronomy"IYA 2009 Coins issued ny Australia
The numismatic collection was really a boost for the IYA 2009 as it needs much reputation.
Other countries are encouraged to launch IYA 2009 stamps to promote astronomy and International Year of Astronomy in general.

Out of both coins, $ 1 coin features CSIRo's Parkes radio telescope known as "The Dish" whereas the 20-cent illustrates a star-gazing amateur astronomer, who is ina background, filled with stars and constellation.

Go here if you want to order the coins online.

The following image shows you the Astrophotographer David Malin and Director of the Anlgo-Australian Observatory, Professor Matthew Colless, at the launch of the IYA coins.
