Watch LIVE: Total Solar Eclipse of 20 March 2015 19 Mar 2015 3:39 AM (10 years ago)

A total solar eclipse is one of the most beautiful natural phenomena to watch. On 20 March at 8:30UT, this nature's beauty will visit Europe and the North Atlantic, allowing millions of people to witness it. Those who have been lucky enough to see a total solar eclipse or even a partial one will agree that it's never really the same to watch it through a computer screen than in person - which I completely agree! However, thanks to dedicated people and groups, we are able to witness it digitally, as it happens, bringing us more closer than we could.

Enjoy the eclipse viewing and if you come across more live webcasts, please drop me a message on comments or via Twitter @ThilinaH

Can MOOCs Educate the Developing World? 16 Feb 2015 4:04 AM (10 years ago)

Here's the larger question: can online classes be used to help not just a few exceptional students, but the developing world at large?

As the guest editor of The Big Future video series by The Verge, Bill Gates discussed this larger question. Gates believes that online courses can bring the world's best teachers to anyone with a smartphone or tablet, for free.

Over at edSurge, a short article discusses Gate's thoughts, "around a third of Coursera’s user base is from the developing world, but nearly 80% of those students already have a college degree--as opposed to 10% of the general population," and adds, "but Gates contends that if MOOCs are geared towards a developing nation’s elite, the courses will only exacerbate the digital divide between haves and have-nots."[1]

In their Foundation's 2015 letter, Bill and Melinda Gates share their bet for next 15 years, "The lives of people in poor countries will improve faster in the next 15 years than at any other time in history. And their lives will improve more than anyone else's" and adds further, "Before a child even starts primary school she will be able to use her mom's smartphone to learn her numbers and letters, giving her a big head start. Software will be able to see when she's having trouble with the material and adjust for her pace. She will collaborate with teachers and other students in a much richer way. If she is learning a language, she'll be able to speak out loud and the software will give her feedback on her pronunciation."
Education is the key to everything and MOOC is the way to go to achieve it. However, there's a big hurdle to cross - accessible technology. In order to improve the education through MOOCs, specially in developing world, we need much improvement in accessible technology. If I narrow it down to a developing country that I'm most familiar with - Sri Lanka - is now the best performer in basic education in the South Asian region, with a remarkable record in terms of high literacy rates and the achievement of universal primary education [2]. Even though the government of Sri Lanka has heavily invested in information and communications technologies (ICT) for distance learning, the lack of resources, low digital literacy, poor guidance, remains at large a problem to reach the mass population of students. From slow and limited internet access to lack of technological infrastructure remains a problem. These are not only to Sri Lanka, but applicable to many developing countries.

Accessible technology is the key to MOOCs future.

Data Visualisation: Gendered Language in Teaching Evaluation 13 Feb 2015 12:43 PM (10 years ago)

Are you a student at a university? Do you describe your female professor as annoying, bossy and ugly or your male professors as intelligent, brilliant and awesome?

Before we jump into any conclusion, I have to say that I'm not too happy to share the results in this post. But I'm glad that someone took the time and effort to create this interactive tool.

Created by Ben Schmidt, a history professor at Northeastern University, the 'Gendered Language in Teaching Evaluation' interactive lets you explore the words used to describe male and female teachers in about 14 million reviews from RateMyProfessor.com It allows you enter specific words to see how they correspond with the professor's gender and teaching discipline.

After playing around a bit myself, the data suggests that students tend to think more highly of male professors than females. Schmidt explains further about the interactive here and seems to be quite engaged through comments to discuss further.

Physics of Love for Valentine's Day 13 Feb 2015 11:56 AM (10 years ago)

It's time again, the romance is oozing from loved ones and singles looking for a date or ignoring the day. For the geeks out there, folks at Symmetry magazine (published by Fermilab and SLAC) created a fun set of physics-themed Valentine's cards for both in-love and out-of-love which ever the hat you are wearing this year.

My favourite from the lot explains, 'if you seek to rekindle (or extinguish) a romance with someone intrigued by the invisible elements of the cosmos, such as the yet-to-be-discovered dark matter, one of these cards might do the trick.'

Head over to Symmetry magazine to check more cards and to print yours. Just make sure that you choose the correct one for your current (or soon-to-be-x) partner.

Happy valentine's day folks! Enjoy wherever you are with whoever you are with (or perfectly fine to let it go as just another day).

Will Be Back 10 Feb 2015 11:26 PM (10 years ago)

Since I moved to full-time freelance work last year (2014), I haven't been able blog that much. It's a myth that freelancers have more time in hand. When you have a full-time job with proper working hours, you stick to those and do bit more as well. But at the end of the day, you end up having time for other things. When freelancing, your work schedule gets filled around the clock, including weekends.

But after an year, I have learned to organise time management much better. I'll be back to blogging soon, with both astronomy and some personal thoughts as well. Maybe here, maybe somewhere fresh.

Another Orbit 24 Apr 2012 11:19 AM (12 years ago)

Universe is too wonderful to not to share with anyone, specially with children. Unfortunately many children discover the beauty of the Universe bit too late, or some never get to enjoy it. That's why I fully support Universe Awareness (UNAWE) - a program which put its heart and soul into inspiring every child with our wonderful Universe, regardless of the social status.

As I complete yet another orbit around the Sun, I couldn't have celebrated my birthday better than with children from an orphanage in Sri Lanka, doing astronomy!

Thank you for everyone who sent in wishes and helped with the event, specially my dad and aunt for helping with cooking, and Kavindi (UNAWE-Sri Lanka), Kaminda, Gihantha, Tijitha, and Janith for helping with the activities.

teaching basic astronomy concepts to kids

tour around the Universe

not only kids, but orphanage staff enjoyed the Universe

lunch time

it's wonderful to see how kids visualize the Universe

kids version of the Universe :-)

kids with UNAWE - Sri Lanka

busy with the "Eggnauts" challenge!

teaching kids is such a rewarding experience

"Tell me and I forget. Show me and I remember. Involve me and I understand"

time to test those "Eggnauts"

it was a wonderful day

Stars of Somalia: Tomorrow is late 7 Aug 2011 10:17 PM (13 years ago)

People in the Horn of Africa, living under the same sky as we live, are suffering from hunger and drought. Join us on August 13 to help the famine victims of Somalia.

Ever since the ancient times human being has been staring at the stars above, wondering what they are. One of these dazzling stars is the Sun, which is closer than any other star to the Earth. Our Sun has witnessed everything happened on Earth; the formation of life, all creatures, existence of human and his eagerness for knowing and finding more about the Universe. The Sun has been a witness to every crisis on earth; happiness and misery as well as war and peace. But recently the Sun is much more displease than any other time as with every dawn it observes the same old story of poverty and starvation in North Africa; this time even wider and much more tragic. The story of the drought crisis, civil wars, and enforced immigration of Somalis to find a secure place to survive, is a remarkable conflict of men against nature and men against his own race.

Many cultural and scientific organizations and NGOs around the Globe are trying to make peace and invite people to put an end to the battle of men against nature. StarPeace believes that all of us should participate in helping of the victims. According to the news, the situation is critical, and the experts warn us that even a small delay has a great impact: “Tomorrow is Late”. StarPeace invite all the members and cooperators to hold a public stargazing night in their cities and towns on August 13 to organize a fund raising event in order to help the drought victims of Somali. Donation might be inadequate, but it may well be sufficient to provide the victims a meal.

We all hope the innocent Somali children, who are enduring a hard time in refugee camps, will soon spend their nights under the twinkling stars of the Sky without suffering from hunger and fear.

Beauty of the Earth and Sky 10 May 2011 10:01 AM (13 years ago)

"I often think that the night is more alive and more richly colored than the day" ~Vincent Van Gogh


For Global Astronomy Month 2011, we held an astrophotography contest "Earth and Sky" in collaboration with The World at Night. The theme of the contest was "Dark Skies Importance”. The submitted photos were judged in two categories: “Beauty of the Night Sky” and “Against the Lights.” We received many entries from around the world. Below is the winning photos from both categories. Going through them will make you realise that words of Van Gogh's couldn't be more right.

The first prize in the Against the Lights category goes to Thomas Kurat for his photo “Alps at Night”. It shows the starry sky above a misty Alpine valley and village lights in Austria.


The second-place winner in the Against the Lights category is Mehdi Momenzadeh from Iran for his panoramic photo “Isfahan Milky Way”.


Third place: “Lisbon Sky Lights” by Miguel Claro from Portugal. The photo shows stars and the crescent moon trail over a landmark bridge in Lisbon dominated by the city’s light pollution.


Fourth place: “Venus above Reunion Island” by Luc Perrot.


Fifth place: “Lights from the Hidden City” by Ben Canales. The photo is taken from mountains near Portland in the United States and displays how the lights from the city illuminate clouds in the night sky.





The first prize in the Beauty of the Night Sky category goes to Stephane Vetter for his photo “A Starry Night of Iceland” which displays the northern lights and the Milky Way above arctic landscape of Iceland.


“Galactic View from Planet Earth” by Alex Cherney from Australia is the second-place winner in the Beauty of the Night Sky category.


Third place: “Beauty of Southern Sky” by Luc Perrot. The French night sky photographer made this panoramic image from Reunion Island in the southern Indian Ocean.


Fourth place: “The Great Wall at Night” by Xiaohua from China. The photo displays the Milky Way above one of the gates to the Great Wall of China.


Fifth place: “Startrails above an Alien Lake” by Grant Kaye. The image shows startrails around the north celestial pole as captured from the bizarre looking structures at shores Mono Lake in California.

Help SETI, Help You! 2 May 2011 11:37 AM (13 years ago)

The recent funding cutback on Allen Telescope Array is quite disappointing, but it’s more disappointing to see people questioning why we should spend so much money on keeping such science alive.

Here’s late Carl Sagan in his own words saying why we should.

To view this is a graphical perspective, John at μcosmologist put together a very nice infograph showing how much we spend on other things compared to the cost to run SETI for a year ($2.5 million).

Below is a part of the infograph. Full version is here. (Many thanks to John for putting this together.)

After watching the video above and the infograph below, if you think you can spare some dollars to help to SETI to get back on track, head to SETI website to donate. The science SETI does is for everyone, for the people. So...


Help SETI, Help You!

Pass it on when you're done with it 21 Apr 2011 5:45 AM (13 years ago)

Another orbit around the Sol concluded on April 18 and another is unfolding. It was an interesting year with many developments, both personally and professionally.

I'm pretty overwhelmed with all the birthday wishes from friends around the world. I want to "Thank You" each and everyone who sent greetings.

Unfortunately I wasn't able to do what I did last year for the birthday, because the kids were busy with a New Year program. But after seeing this moving campaign video done for Sri Lanka Eye Donation Society, I decided to donate my eyes on the morning of my birthday.

Hopefully, someone will get use of my eyes, when I'm done with it.

6th worldwide GLOBE at Night 2011 campaign 19 Feb 2011 7:11 PM (14 years ago)

Less of Our Light for More Star Light
- Join the 6th worldwide GLOBE at Night 2011 campaign: Feb. 21 - March 6




With half of the world’s population now living in cities, many urban dwellers have never experienced the wonderment of pristinely dark skies and maybe never will. This loss, caused by light pollution, is a concern on many fronts: safety, energy conservation, cost, health and effects on wildlife, as well as our ability to view the stars. Even though light pollution is a serious and growing global concern, it is one of the easiest environmental problems you can address on local levels.

Participation in the international star-hunting campaign, GLOBE at Night, helps to address the light pollution issue locally as well as globally. This year, 2 sets of campaigns are being offered. For the first campaign from February 21 through March 6, 2011, everyone all over the world is invited to record the brightness of the night sky. The second campaign runs from March 22 through April 4 in the Northern Hemisphere and March 24 through April 6 in the Southern Hemisphere. The campaign is easy and fun to do. First, you match the appearance of the constellation Orion in the first campaign (and Leo or Crux in the second campaign) with simple star maps of progressively fainter stars found. Then you submit your measurements, including the date, time, and location of your comparison. After all the campaign’s observations are submitted, the project’s organizers release a map of light-pollution levels worldwide. Over the last five annual 2-week campaigns, volunteers from more than 100 nations contributed 52,000 measurements, one third of which came from last year’s campaign.

To learn the five easy steps to participate in the GLOBE at Night program, see the GLOBE at Night website. You can listen to last year’s 10-minute audio podcast on light pollution and GLOBE at Night. Or download a 45-minute powerpoint and accompanying audio. GLOBE at Night is also on Facebook and Twitter.

The big news is that children and adults can submit their measurements in real time if they have a smart phone or tablet. To do this, you can use the web application. With smart phones and tablets, the location, date and time are put in automatically. And if you do not have a smart phone or tablet, there are user-friendly tools on the GLOBE at Night report page to find latitude and longitude.

For activities that have children explore what light pollution is, what its effects are on wildlife and how to prepare for participating in the GLOBE at Night campaign, see the Dark Skies Rangers activities. Monitoring our environment will allow us as citizen-scientists to identify and preserve the dark sky oases in cities and locate areas where light pollution is increasing. All it takes is a few minutes during the 2011 campaign to measure sky brightness and contribute those observations on-line. Help us exceed the 17,800 observations contributed last year. Your measurements will make a world of difference.

Report: "A Match Under Starlight" 27 Jul 2010 10:40 AM (14 years ago)

Beginning of July 2010 concluded one of the most exciting sporting event - FIFA2010. While many football fans around the world celebrated the victories and the losing, Astronomers Without Border's National Coordinator for Iraq - Azhy Hasan came up with the idea to celebrate the World Cup with a touch of astronomy and peace - "A Match Under Starlight".

Amateur Astronomers Association of Kurdistan celebrated the event by gathering a youth group to play a football match which was followed by an observation session. Players enjoyed beautiful views of Saturn and medals for participating in the match. Azhy who organized this event took the extra effort to show the unity of other AWB member countries by displaying the national flags and playing the national anthems. You can see some unforgettable photos and a video of the event here.

This wonderful event was also celebrated by UNAWE - Romania. With the collaboration of “Angela Gheorghiu” School from Adjud, Vrancea, UNAWE Romania, organized a football game with 23 children aged between 5 and 9. All the children were awarded with a "Stellar Football Player" diploma for their enthusiasm and spirit. You can see this wonderful effort in a report with photos put together by Catalina Movileanu of UNAWE - Romania here.



Another event to celebrate the project was organized by “Rudolf Walter” foundation – Timisoara branch, the Astronomical Observatory of Timisoara, and the “Antares” astro-club of Timisoara. Kids at the “Rudolf Walther” foundation (a model institution where disadvantaged kids are educated and cared for) got to play football which was followed by 3-D projections and captivating talks. The kids got a special treat as well, Andrei Juravle – owner of astrovest.ro – donated a telescope. You can read a report of this event with photos put together by Virgiliu Pop of Romanian Space Agency here.


Many thanks to everyone who participated in this wonderful project highlighting world peace and the joy of togetherness. We hope you will join us in future events.

Totality and Victory 11 Jul 2010 6:14 PM (14 years ago)

During the 5-hour event, sky watchers spent as much as 4 minutes completely enveloped in the Moon's shadow watching in awe as the solar corona revealed itself to the human eye.

As soon as the eclipse ended, photos started pouring in, and it was a well treat for everyone. Below are some of the best images available up to now ( 5:30UT 12 July 2010). Enjoy!









It was a fantastic Sunday with the Total Solar Eclipse and the FIFA 2010 finals. If you missed the eclipse live feed, check the below video complied by Reuters.

Blind Date With An Asteroid 10 Jul 2010 3:04 PM (14 years ago)

We know how blind dates are, always not sure of what to expect! This was how exactly felt by ESA scientists and rest of the world watching the live web cast of ESA's Rosetta spacecraft's flyby of 21 Lutetia; the largest asteroid ever to visited by a satellite.

After weeks of maneuvers and optical observations, Rosetta is perfectly lined up to skim by the asteroid only 3,162 km (2,000 miles) away. ESA hosted a live web cast at 16:00 GMT on July 10 which was followed by many around the world.

I managed to watch the live web feed while Tweeting (@ThilinaH) and sharing updates on Facebook as well. It was a great experience and below are some stunning images of the Asteroid Lutetia.





Rosetta will continue on to its primary target, comet Churyumov-Gerasimenko. It will rendezvous with the comet in 2014 and accompany the comet for months, mapping it and studying it. Then in November 2014, Rosetta will deploy Philae to land on the comet nucleus.




Until then the ESA scientists will spend time getting to know this newly found friend (then stranger), analyzing data.
