#ThrowbackThursday post: June 6, 2012 Transit of Venus

June 6th last year, stargazers from across the globe gathered together to watch one of the rarest astronomical spectacles.

Many turned their attention to the daytime sky to view the planet Venus passing directly between the Sun and Earth – a transit that won’t occur again for another 105 years.

The transit of Venus happens in pairs eight years apart – but then with more than a century between cycles. During the pass, Venus appeared as a small, dark round spot moving across the face of the sun.


Venus Transit Observation in the Philippines

Viewing the Sun’s mole: People across the globe witnessed a very rare spectacular event that won’t be repeated until 2117.

I observed the whole duration of the  final  Transit of Venus of our lifetime at the College of Science Amphitheater in UP Diliman in a public viewing event  called ‘Rekindling Venus’ organized by members of various school-based astronomy organizations in the Philippines a last June 6, 2012.

There were lectures, talks, astro-images exhibit, free planetarium shows and telescope viewing, and more during the event, which have been attended by a lot of astronomy-enthusiasts coming from different places.

The sky was about 40-50% cloudy that day but it didn’t rain despite the weather forecast.

Observers set up their telescopes and pointed at the sun to view the transit.

Local newsgroups were present during the event and I was unfortunately spotted for a short interview. Haha!

This event was surely a memorable one.

Kudos to all the organizers and thank you to everyone who joined us in this event!


Rekindling Venus: Experience A Rare Celestial Event

Next month we will be the last people living today to witness one of the rarest astronomical events. On June 6, a special celestial event called the transit of Venus will take place, and it won’t be repeated in your lifetime.

During the transit, Venus will pass directly in front of the sun from Earth’s perspective, appearing as a small moving black dot.

The entire transit can be witnessed from eastern Asia, eastern Australia, New Zealand and the western Pacific, as well as Alaska, northern Canada and almost all of Greenland.

How rare is this astronomical event?

Transits of Venus occur in a pattern that repeats every 243 years with pairs of transits eight years apart separated by gaps of 121½ years and 105½ years. Only six of these transit have been recorded by civilization: 1639, 1761, 1769, 1874, 1882, and 2004. This June’s transit, the end of the 2004-2012 pair, won’t be repeated until the December 2117. This is the last chance for anyone alive today to see the rare celestial sight. Fortunately, the event is widely visible.

Unlike a total eclipse of the sun, which is visible only within a long narrow track traced by the moon’s shadow, during the 2012 transit of Venus the entire hemisphere of Earth facing the sun will get to see at least part of the planet’s solar crossing.

Importance

Astronomers during the 18th Century travelled thousands of miles and risked their lives to witness this precious sight.

They did so because they believed Venus held the key to the most pressing astronomical quest of the age: the size of the solar system.

In 1716, astronomer Edmund Halley realized that by timing the transits of 1761 and 1769 from widely-spaced locations on Earth it should be possible to triangulate the distance to Venus using the principles of parallax and give the distance between Earth and the Sun.

For astronomers today, the Transit of Venus offers a chance to gain insights into the planet’s notoriously thick, cloudy atmosphere, and use the refraction of sunlight to finetune techniques for hunting planets orbiting distant stars.

One of the most useful exercises will be to compare observations of the transit made by Earth-based telescopes, orbital telescopes and robot probes.

The Transit of Venus (TOV) is among the rarest astronomical phenomena and won’t happen again until the year 2117. So prepare now, and don’t miss out on this extremely special event!

Observing the TOV from the Philippines

Filipinos are lucky because the entire Philippines is well positioned to witness the transit of Venus on Wednesday 6th June 2012.

Safe Viewing

Warning: NEVER look at the sun with your naked eye, binoculars or a telescope. Serious and permanent eye damage, including blindness, can result.

The Black Drop Effect

The black drop effect occurs when Venus appears to “connect” to the edge of the Sun before actually reaching the edge. You can model the black drop effect by slowly pinching your index finger and thumb together. Your fingers seem to meet even before they touch. This optical phenomenon was originally thought to provide proof of Venus having an atmosphere. For an explanation of the black drop effect, check out the following links:

IAU Gala Night at the NIDO Fortified Science Discovery Center

Last October 21, 2011, I attended the International Astronomical Union (IAU) Formal Gala Dinner  at the Science Discovery Center in SM Mall of Asia, Pasay City.

Fellow members from my org, UP Astronomical Society; professors and students from different universities namely UPLB, RTU, and DLSU; astronomy educators, and amateur astronomers were also attendees of this gathering.

IAU Gala Night – October 21, 2011

The event’s theme was ‘Astronomy for Development’. It aimed to educate and promote awareness of Astronomy among Filipinos. It was also to inform the people about the importance of astronomy and to let them know the latest development and innovation in the field.

Speakers were Dr. Rogel Mari Sese, Head of Astrophysics Lab in the Institute of Mathematical Sciences and Physics, UPLB; and Dr. Kevin Govender, the current Director of the IAU Office of Astronomy for Development.

Before proceeding with  the talks, a short  planetarium show entitled “New Horizons” was played to entertain the audience. It was an all-dome-video experience that features a majestic journey through our celestial neighborhood.

Dr. Sese was the first one to deliver a talk. He discussed several key ideas in pursuing Astronomy as a profession particularly in the Philippines. He further explained that having a career in astronomy is challenging and highlighted a few important points on what in takes to be an astronomer. These, according to him are the following:

  • Passion – main motivation for one to learn
  • Plan – [Because] the learning journey is long
  • Perseverance – main motivation for one to finish

He finished his talk my leaving this inspiring message: “Be passionate and patient. It’s all worth it in the end.”

Meanwhile, Dr. Govender gave a talk about the importance of astronomy in the society. He also mentioned the current promotional strategies of IAU to  stimulate people in astronomy and to establish Astronomy Education, Research, and Outreach in developing countries such as the Philippines. Moreover, he emphasized several important points about Astronomy and Science:
“Astronomy stretches our imagination.”
“Science is about exploring God’s universe.”
“Astronomy for a better world.”

A short open forum was eventually held after the talks to allow questions from the audience. A lot of curious questions about astrophysics have been asked by several students until after the formal dinner.

All in all, the event was truly a great and memorable experience.

I’m glad that IAU is still taking its commitment in expanding astronomy development programs in areas where astronomy is still an emerging and minor field (such as in the Southeast Asian (SEA) region), even after the successful International Year of Astronomy (IYA 2009) was over. At the same time, I’m also proud that the Philippines is already taking part in holding activities such as this which enable  young astronomers and students in particular, to further develop their interest in the field.

The purpose of this office is to use astronomy to make the world a better place!

I hope that there would be more scientific collaborations such as this one, in the near future  that could stimulate the rapid growth of science among developing societies.

Ad astra per aspera!
