Venus' Transit 2012

Transits of Venus are exceptionally rare astronomical phenomena. A transit of Venus happens when the planet directly passes between the Sun and the Earth. These transits come in pairs eight years apart but are separated by at least a century.

A transit of Venus will be visible here in the Philippines on June 6, 2012. The last sighting was in 2004. The next one will occur in 2117. Thus, this is an event not surely to be missed.

Basically, it is an eclipse of the Sun by Venus. We should see Venus as an apparent dark spot passing across the face of the Sun from around 6:00am until 1:00pm. But be reminded that proper eye protection must be used in observing the transit. Solar filters are available in specialty stores.

Shown above is a simulation of the Venus Transit as viewed on June 6, 2012 from an Altitude-Azimuth mounted telescope. The loop is an effect of field rotation in Alt-Az mounted telescopes. However, Venus should be apparently traveling in a straight path across the face of the Sun when viewed on transit.

Transits provide opportunities for Scientists for more research. This is the main reason why many people travel miles just to have the chance to observe the transit. Astronomers are given the opportunity to search for exoplanets. Scientists are able to compare Venus' diameter from past recordings. Besides that, more information about the atmosphere of Venus will be provided. These phenomena also provided more evidence about the distances between the heavenly bodies.

Because this is an astronomical event not to be missed, UP Astronomical Society in collaboration with the Australian Embassy, UPLB Astronomical Society, RTU Astronomical Society, UP PreMedical SocietyDOST-PAGASA, and D'Great Rovers presents REKINDLING VENUS. A special coverage of the transit of Venus this June 6, 2012 at the UP Diliman College of Science Amphitheater.

The event is open and free for all, so bring your friends with you in this rare phenomena. See you on that special Wednesday morning, June 6th! For more information, contact Anj 09179494755, Dean 09175807420, or Nico 09264241505. You may also visit our event page for more details.

NAW 2012

In celebration of the National Astronomy Week 2012, UP Astronomical Society with the partnership of the Philippine Society of Youth Science Clubs, presents a week long celebration this February - March, 2012!

National Astronomy Week (NAW) is an annual celebration every third week of February in the Philippines (Presidential Proclamation No. 130). Astronomy enthusiasts such as the University of the Philippines Astronomical Society, participate in the celebration through activities set for the public.

The celebration starts off with Lakbay Langit at Siena College of San Jose in Bulacan this February 18-19. UP Astronomical Society's Lakbay Langit is a roaming astronomy camp that allows students to discover the skies in a whole new light. Lectures, sky gazing activities, workshops, and fun games make up the itinerary of the event.

Next stop is the Dorm Visit at UP Kalayaan Residence Hall this February 21. UP Astronomical Society arranges visits to dormitories to be able to reach out to astronomy enthusiasts, as well as to be able to provide awareness of astronomy to students in the University.

But the fun does not stop there! PAGASA Astronomical Observatory's Open House on February 22 provides a medium for the public to get to visit and know more about us. Visitors get the chance to see the wonders of the sky through the Country's Largest Telescope named "Andre the Giant".

Through one of the main objectives of UP Astronomical Society, which is to broaden the awareness, interest, knowledge, and understanding of astronomy among students and the general public, that the first Big Bang! was created. Big Bang is an astronomy quiz show that caters to high school students across Metro Manila. It started during the National Astronomy Week of 2007 with the assistance of the DOST-SEI and of UP NISMED. This year, the event shall take place at UP NISMED too this February 25.

Take-off! on the other hand, is a bottle-rocket making competition for high school students, which aims to develop ingenuity in the minds of the students. This competition also commemorates the great help of rockets to launch the most important astronomical observation instruments such as space probes, space telescopes, and astronauts. This event will take place at the UP NISMED and at the UP Sunken Garden on February 25, simultaneous with the Big Bang!

Aside from these activities, UP Astronomical Society also hosts the Sidewalk Astronomy or Siliptala. This activity is a free public observation, which includes stargazing, telescope viewing, and basic astronomy lectures. The organization visits different locations and caters to people of various fields of experience. On March 3, another Sidewalk Astronomy experience shall take place at the UP-Ayala Technohub, Diliman, Quezon City.

Another Public Observation shall take place on this year's NAW celebration. The organization shall be hosting an observation on the Conjunction of planets Venus and Jupiter this February 26-27. UP Astronomical Society has since then hosted various observations, from meteor showers to lunar eclipses, which is open to the public for free.

And to top it all, the organization aims to reach out to communities who are unfortunately unable to experience astronomy related activities through its final event, Astrosoc Outreach. This shall take place on the 17th of March.

Hence, the celebration of the National Astronomy Week by the UP Astronomical Society shall be a astronomy experience-rich and fun-filled series of events! But none of these will be possible without the help of our partner in this week-long celebration, the Philippine Society of Youth Science Clubs. We would also like to thank our major sponsors Moonleaf Tea Shop and D' Great Rovers, and our minor sponsors The Mind Museum, Blessings Book Binding and Photocopying Services, and Heat Flow Construction Corporation.

Join us as we partake on this celebration. Feel free to contact Carlo 09065880080 or Beb 09277086047, email us at, or follow us at UP Astrosoc's Twitter Page or at UP Astrosoc's Official Fan Page.

Lakbay Langit: Astronomy Camp


UP Astronomical Society's Lakbay Langit is a roaming astronomy camp that allows students to discover the skies in a whole new light. Lectures, sky gazing activities, workshops, and fun games make up the itinerary of the event. Surely, this activity has left in the students' minds a mark of raised interest and enthusiasm in Philippine astronomy.


• Promotion of Astronomy to students through a camp of games, lectures, and activities
• Endorsement of the other astronomical/ organizational events of UP Astronomical Society
• Publicity of UP Astronomical Society as a catalyst to gathering the youth as a market for involvement in UP Astronomical Society’s activities
• Fostering of communal relations and collaborations between UP Astronomical Society and schools
• Assessment and dissemination of astronomical knowledge and know-how to participants of the event and other attendees


UP Astronomical Society (UP AstroSoc) takes to its hands the challenge of bringing astronomy beyond its walls and into the hands of people. Chief of the goals and objectives of the organization are to open people’s eyes to what is great about astronomy and to broaden what they know about the heavens above.

Astronomy camps are a great venue for students and people in general to get to know what is up there. Through astronomy camps, students get to experience in an overnight event what it means to be an amateur astronomer. With workshops, lectures, games, and other activities aimed at presenting astronomy as fun and enticing, astronomy camps are the perfect way to reach out to the people and tap their minds to see the universe.

For more information about Lakbay Langit, email us at
