Bandar Seri Begawan – Look west in twilight on February 20 and 21 as two planets, Venus and Mars, appear close one another in the sky and will be accompanied by the thin moon crescent. The celestial phenomena known as conjunctions occur when celestial bodies have the same right ascension or the same ecliptic longitude as seen from the Earth. While it would be very low in the twilight sky, it might be an interesting photo opportunity. Venus will be shining bright in the west after sunset and sky gazers can locate Mars as they are separated within 1 degree apart. If the weather cooperates, it could be a spectacular image.

Bandar Seri Begawan – There will be a close pairing of the moon and the planet Venus, a perfect chance to all stargazers to enjoy witnessing an astronomical event with family and friends this Hari Raya.
Gaze the western horizon on these days August 9 and 10, 2013, just after sunset, at around 6:35 pm and you will be greeted with a beautiful sight: the crescent moon beside a very bright star-like object, the planet Venus. The event will be visible to the naked eye and does not require any special equipment. Clear sky and Selamat Hari Raya Aidilfitri.
To use the accompanying map, turn it around until it matches the view in your binoculars. Start your tour by learning the Moon’s large, dark plains, called maria (the Latin plural of mare, “sea”). Early telescope users and mapmakers in the 17th century thought these dark markings were similar to Earth’s bodies of water and gave them fanciful names like Mare Nectaris, “Sea of Nectar,” and Mare Nubium, “Sea of Clouds.” Today we know that the Moon is an airless, waterless, and lifeless world. The maria are in fact great lava flows that filled much of the lunar lowlands billions of years ago.
When the Moon is a slender crescent in the western sky after dusk, we see the features near the right-hand edge of the map. As you can see, Mare Crisium and Mare Fecunditatis are the only major “seas” visible. In the next few days the retreating terminator gradually unveils Mare Nectaris, Mare Tranquillitatis, and Mare Serenitatis. At first-quarter phase we see the entire right half of the map. After first quarter Mare Imbrium and Mare Nubium appear, and just before full, Oceanus Procellarum and Mare Humorum come into view.
At full phase the Moon is at its dazzling brightest. Because the Sun shines onto the Moon from almost directly behind us at this time, we see no shadows of craters and mountains. The bright ray system of the craters Tycho, Copernicus, and Kepler stand out especially prominently. The rays are splash patterns of debris from the impacts that formed the craters. After full phase the advancing terminator covers up the surface in the same right-to-left order.
Unlike astronomical telescopes, which give inverted (upside-down) and sometimes mirror-reversed images, binoculars show you right-side-up views that are never mirror-reversed, making comparison with the lunar map very easy. Once the map is oriented properly, you will be able to readily identify the major seas, craters, mountain ranges, and other features. In time the geography of this alien world will become as familiar to you as that of our own.
The moon, mighty Jupiter and bright stars cluster of Pleiades appear in celestial conjunction on the night of Dec 25, 2012. Stargazers will be able to see the moon is closed to the planet and stars cluster through the night sky. A great opportunity to all astrophotographers in Brunei to capture the spectacular event.
