Bandar Seri Begawan β A perfect alignment of the 3 celestial bodies, Earth-Moon-Sun, will occur on Sunday June 21, 2020, resulting in a spectacular annular solar eclipse which can only be view from specific areas on Earth.
The annular phase of this solar eclipse will be visible from parts of Africa including the Central African Republic, Congo, and Ethiopia; Asia in Yemen, Oman, south of Pakistan and northern India, China including Taiwan. You must be located within the narrow path of annularity represented on the map above by a red line (about 11,400 km long and 21 km width), where people in these areas will see the characteristic “ring of fire”.

Paris β Sebanyak 110 pasangan nama exoplanet dan bintang induknya diberikan nama melalui kempen IAU100 NameExoWorlds telah diumumkan di sidang media di Paris pada 17 Disember 2019. Bersempena ulang tahun Kesatuan Astronomi Antarabangsa (IAU) yang ke-100 pada tahun ini, kempen di peringkat nasional telah dianjurkan di 110 negara yang melibatkan penyertaan lebih dari 780,000 orang di seluruh dunia, untuk mencadangkan dan memilih nama-nama bagi setiap exoplanet dan bintang induk negara masing-masing.
Projek IAU100 NameExoWorlds telah melihat penyertaan yang meluas dan
besar-besaran di seluruh dunia untuk memberikan masyarakat umum peluang untuk
mencadangkan nama-nama sistem exoplanet yang bermakna, kreatif dan unik bagi
negara masing-masing. Penganjuran ini adalah kali yang kedua dalam sejarah di
mana sebuah kempen telah menghasilkan penamaan bintang dan exoplanet. Pada keseluruhannya,
sebanyak 360,000 cadangan nama telah diterima dari 110 negara. Penganjur program
di setiap negara telah menyenarai pendekkan nama-nama yang dicadangkan, dan
seterusnya dibukakan bagi pemilihan melalui undian kepada orang ramai. Seramai
420,000 orang telah mengundi calon-calon nama yang diberikan. Projek ini akan
memberikan kesan yang berkekalan di mana nama-nama yang dipilih sebagai
pemenang akan digunakan selari dengan tatanama saintifik yang sedia ada dengan
penghargaan kepada individu, kumpulan ataupun institusi yang telah mencadangkan
nama tersebut.
Paris – More than 110 sets of names of exoplanets and host stars named in the IAU100 NameExoWorlds campaigns were announced at a press conference in Paris (France) on 17 December 2019. Within the framework of the International Astronomical Unionβs 100th anniversary commemorations (IAU100) in 2019, more than 110 countries organised national campaigns that stimulated the direct participation of over 780 000 people worldwide, who proposed and selected names for each exoplanet and its host star.
The IAU100 NameExoWorlds project saw massive and widespread participation around the world, as the public eagerly engaged in this exciting opportunity to suggest meaningful, creative and unique names for exoplanet systems for their respective countries. This is only the second time in history that a campaign has led to the naming of stars and exoplanets. Overall, 360 000 proposals for names were received from 110+ countries. The National Committee in each country reduced their proposals to a shortlist of national candidates, which were presented to the public for their votes. A total of 420 000 people voted for their preferred candidates. This project will have a lasting impact, as the winning names will be used in parallel with the existing scientific nomenclature, credited to the person, group or institution that suggested them.
“Astronomical observations over the past generation have now discovered over 4000 planets orbiting other stars β called exoplanets. The number of discoveries continues to double about every 2Β½ years, revealing remarkable new planet populations and putting our own Earth and Solar System in perspective. Statistically, most of the stars in the sky are likely to be orbited by their own planets β they are everywhere,β said Eric Mamajek, co-chair of the NameExoWorlds Steering Committee. βWhile astronomers catalogue their new discoveries using telephone-number-like designations, there has been growing interest amongst astronomers and the public alike in also assigning proper names, as is done for Solar System bodies,β Mamajek continued.

Bandar Seri Begawan β People of Brunei will have the
opportunity to name a selected exoplanet and its host star to commemorate the
100th-anniversary celebration of the International Astronomical Union (IAU).
Currently there are a total of
more than 4,000 confirmed planets that orbit stars outside the solar system
known as exoplanets. Most of these exoplanets have no proper names.
NameExoWorlds offers the opportunity for all countries
in the world including Brunei Darussalam to give a name to one exoplanet and
its hosting star.

Bandar Seri Begawan – On Dec 26, 2019, an annular solar eclipse will occur from few cities in Borneo, on the narrow track of the Moon shadow. Yes you have you be along the eclipse path to witness this special kind of eclipse of the sun – and we will bring you there! The celestial alignment happens when the moon passes in front of the sun, but the orbit of the moon is a little further away from the Earth and the moon does not completely cover the sun.
It will be a very spectacular sight, when a βring of fireβ or annulus surrounds the sun at central eclipse. Watch a “string of beadsβ (Bailyβs Beads Effect) on the edges of the sun during the beginning of annularity eclipse. As the horizon darkens to deeper blue than normal, observe the animals reacting to the dramatic changes in the sky. Look for the brightest planet, Venus, shining east of the sun at mid-eclipse. Jupiter, Saturn and Mercury are up there too, but they are fainter and so will be harder to see. This is a rare celestial event as the next annular eclipse will take place in Borneo in 2031.
The visible surface of the sun in a fiery ring around the moon can still blind you. So be sure to watch indirectly, or with special filters. Do not look at the sun directly without eye protection at any time during this eclipse. PABD will provide each member with an eclipse glass (included in your package) for this expedition.

Bandar Seri Begawan – A perfect alignment of the Earth-Moon-Sun bodies will occur on December 26, 2019, resulting in a spectacular annular solar eclipse visible in few cities of Saudi Arabia, India, Sri Lanka, Sumatra, Borneo and the Pacific Ocean .
Partial Eclipse from Brunei Darussalam
As seen from a location on Earth, a solar eclipse happens when the moon moves in front of the Sun thus block the Solar disk. It is a miss, as people in Brunei will only see a partial eclipse with 85.8% obscuration of the Sun by the Moon. A simulation of the partial Solar Eclipse as seen from Brunei during mid-day is shown in the video below.
