Partial Lunar Eclipse visible in Maldives on 31 December

A partial lunar eclipse will occur on 31 December 2009, right before the new year rolls on, and is to be visible in the Maldives. This partial eclipse involves the Moon just barely passing through the Earth's umbral shadow and hence will be only very minor. You are likely to not notice the eclipse unless you are actively watching out for it.

The penumbral phase of the eclipse starts at 10:15 PM on 31 December 2009 and ends 2:30 AM on 1 January 2010, Maldivian time. The umbral phase, which you will see, starts 11:51 PM on 31 December 2009 and ends 12:55 AM on 1 January 2010, Maldivian time.

More details can be found at NASA's "Eclipses during 2009" page.

International Year of Astronomy event by the Maldives Science Society

As you may already know, this year is being celebrated worldwide as the International Year of Astronomy. The effort, an initiative of the International Astronomical Union and UNESCO, intends "to help the citizens of the world rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery". And now, thanks to the hard work from the newly formed Maldives Science Society (MSS), Maldives will be joining in too.

MSS has organised for Dr. Kavan U. Ratnatunga, a Sri Lankan astronomer and Senior Research Scientist at Carnegie Mellon University (US), to travel to the Maldives and deliver a presentation. His presentation titled "The Universe as viewed through the Hubble Space Telescope" will center around the Hubble Space Telescope. It is a topic he is very much qualified to lecture - he has worked at NASA and has authored numerous research papers on various analyses and investigations of Hubble's snapshots of the universe.

The presentation is scheduled for 8:30pm - 11:00pm, 11th of February at the MCSE Seminar Room, Male'. If you are in Male' and interested in science and astronomy then it probably will be worth your while to attend the presentation. More details of the event are on the MSS Facebook event page and I presume updates will appear on the MSS website as well.

I commend the guys at MSS for putting so much of their time and their own money into making this event a reality. I hope they can make arrangements to participate in atleast some of the IYA cornerstone projects. The IYA Galileoscope project, which has developed a high-quality low-cost telescope kit, holds a lot of promise for MSS to make it possible for the public, especially kids and teens, to truly experience the universe through the lens of a real telescope. I, for one, had tears well up in my eye the first time I saw the rings of Saturn up close on a telescope... how will you react?

Browsing the sky with WorldWide Telescope (and Google Sky)

I am hooked... to WorldWide Telescope! I love Google Sky and am an avid fan of it, but this new software from Microsoft Research kicks it all up a notch. WWT gives access to images of the sky from various different databases including the DSS optical, infrared and even the WMAP microwave imagery in a really slick, smooth interface. I've spent a good few hours today browsing through the sky, literally, and reading up.

Here is an image of the Orion belt I snapped from WTT. These three stars are part of the Orion constellation and are among the most prominent and easily identifiable stars in the skyscape. In fact, any Maldivian who has ever looked up at the night sky should recognize them. It is one of the first star constellations that I had learnt of and was a source of great wonder when I was a kid.



And here is an image of the planet Mars - the (almost) unmissable bright red dot in the sky. Many Maldivians seem to have a special relationship with Mars - as demonstrated by a habit of falling for the Mars sunrise-from-west doomsday fantasy hoax and the Mars as-large-as-Moon hoax. I think it might be appropriate for all those people to see the planet up close. :-)



It is amazing that through modern technology, merely equipped with free software like the WWT or Google Sky (and its web version), that anyone of us can now zoom on these and other objects in the sky and enjoy a whole new level of awe and appreciation of the world around us...

Lunar eclipse photos

Here are some snaps of the moon during this morning's total lunar eclipse. The images are nothing special (and of pretty low quality) but given that I had no equipment other than an outdated digital camera this was the best I could have done.











Total lunar eclipse - not visible in the Maldives

I just scanned over the news headlines of the Maldivian media to see if there has been any mention of the lunar eclipse that is to take place tomorrow morning but, quite unsurprisingly, found none. Anyway, I thought I'd dish out some useful info for anyone interested in it.

Although tomorrows eclipse is a total lunar eclipse the eclipsing will not be visible in the Maldives as the moon sets well before it happens. Instead, Maldives will witness what is known as a penumbral eclipse starting 5:34 AM on 21 Feb (local time) as the Moon enters the penumbra - which, sadly, most likely will not bring about much discernible difference for the naked eye. At the time, the moon will be well on its way to set and can be seen approximately West-Northwest at an elevation of 9.5 degrees in the sky. The moon sets at 6.18 AM, which is well before the partial eclipse phase kicks off at 6.43 AM.

If you are disappointed, then wait for the partial lunar eclipse that is to take place on the 16 of August this year which should be clearly visible throughout the Maldives. As for me, I hope to be up tonight watching this magnificent event here in the UK where the total eclipsing is to be visible - it truly is a wondrous sight after all!

Hope that was useful. :-)

Explore the sky!

I still remember the time I first saw the planet Saturn, with it's glamorous-mysterious rings, on a borrowed low-end refracting telescope. I had spent hours tuning and adjusting for better focus while scouring the sky for that normally elusive close-up of one of the most sought after beauties that the heavens hold. I stood awestruck as the dot-in-the-sky got magnified enough times for my eyes to feast upon. The huge planet floated there in deep dark space peacefully minding its own business - just as it had been since Galileo set his sights on it. The planet was within the grasp of a single eyeful on the telescope yet knowing that it was hundreds of times larger than the Earth (Saturn's volume is over 700 times larger than that of Earth) made the experience all the more surreal!

The whole event changed something deep within me. Looking at Saturn from my telescope on that quiet, dark night made me feel like I was looking at myself on the surface of the Earth from afar. It made me realize how SMALL and INSIGNIFICANT I was! The universe was bigger than me - it was even bigger than the 2 km2 island of Male' that I had lived all my life. Heck, it was much bigger than the distance to the furthest place I had travelled. There were an unimaginable number of planets and stars existing for a time much much longer than my (statistically) expected 75 years on Earth. There I was, a mere blip both in space and in time. Till that moment, I had been an arrogant human being just like most others, walking tall and claiming the universe as being almost subservient to my random wishes. The apparent meaninglessness of being a random replicator that infected the surface of a random planet in a random galaxy, in a universe that could boast to contain millions upon billions of stars and planets, is just too overwhelming to be said. Yet, in that moment of understanding, hints of something very elegant, with purpose and more beautiful a meaning than I had supposed shone through brightly.

I would encourage everyone to dish out for a telescope and start gazing at some of the wonders that are out there. If you can't afford one quite yet, then do read up a little about the universe and our solar system and grab a copy of a sky map to help you identify the stars in the sky so you know which is which. The stars would soon loose their role as mere dots of light or hanging lamps on the black canopy of the night sky and become real, tangible objects - as real, as meaningful and often grander than the planet we walk on.

I wish there was an observatory in the Maldives for the public - an amateur one at the least. I surely would build one myself if I had the funds. It would do so much, I believe, to instil a sense of wonder and a much needed appreciation of science (as compared to technology!) in the country and hopefully make people a bit more aware of just how "significant" they really are. Sigh...

PS: Google has added a brilliant new feature to their already awesome Google Earth software - maps of the SKY! Traverse the visible universe on your computer ;-)
