Announcements & Features

1) IAU: Under One Sky

In 2019, the International Astronomical Union (IAU) is celebrating its 100th anniversary. To commemorate this milestone, the IAU is organising a year-long celebration to increase awareness of a century of astronomical discoveries as well as to support and improve the use of astronomy as a tool for education, development and diplomacy under the central theme "Under One Sky".

The centennial celebrations will stimulate worldwide interest in astronomy and science and will reach out to the global astronomical community, national science organisations, societies, policy-makers, students, families and the general public.

There are no events planned for Singapore but there are events in Malaysia, Indonesia and Phillipines. So if you are interested in travelling over, you can find out more here.

Major Astronomical Events

1) Geminids Meteor Showers
This year, the Geminids Meteor Shower will be visible from the 6th to 17th of December, reaching its peak on the 14th of December. Being one of the most spectacular meteor shower of the year, there would be up to 120 meteors per hour during its peak. 
From Singapore, we would be able to see around 59 meteors per hour as the radiant of the shower would be high up in the sky at 36° above the north-eastern horizon at midnight. The Moon will be 7 days old, a waxing crescent at the point of viewing thus making significant interference in the evening sky. The moon will rise at 18:25 and set at 00:26 therefore chances of seeing some good meteors this year is still considerably high. A good technique to watch the meteor showers is to gaze at a dark patch of sky about 30°- 40° away from the radiant.

2) Comet 46P
The comet 46P/Wirtanen is a short period comet with a current orbital of 5.4 years. Discovered in 1948 by Carl A. Wirtanen, the comet would have its brightest pass by in 20 years on the 13th of December. From Singapore, it would be visible in the evening sky from around 19:25, 43° above the northern horizon. Standard binoculars would be required for viewing this astronomical event. Finder charts for the comet are also available online.

What's up in the Sky?

Above the North this month, flanked by her saviours, Pegasus and Perseus, is Andromeda, daughter of Cepheus, with her mother Cassiopeia closer to the Horizon.

While being a small constellation, Andromeda is well-positioned – it is right next to both of our galaxy’s large neighbours, Andromeda Galaxy (M31), the brightest spiral galaxy in the sky, and Triangulum Galaxy (M33) a bright spiral galaxy in its own right. One can find these galaxies by extending both ends of the line connecting Mirach and μ Andromedae, with Andromeda Galaxy being the one further west and closer to the horizon than its counterpart. Beside Andromeda is a smaller constellation, Triangulum, which is useful for finding NGC 752 (Caldwell 28) between Almaak and Mothallah. Thereafter, M34, the Spiral Cluster, can be found by extending a line from Mothallah through β Trianguli.

Below Andromeda and Triangulum, are the constellations of Perseus and Cassiopeia, home to a dearth of deep sky objects. Pacman Nebula (NGC 281) can be found by tracing the line from Shedir to Mirphak, while the Owl Cluster (Caldwell 13) can be found between Caph and Mirphak. The Double Cluster (Caldwell 14), a favourite for amateur astronomers and approximately the location where the Perseid meteor shower originates, can be found between Ruchbah and Mirphak. By extending a line through Navi (γ Cas) from Caph, one can find NGC 129, an open cluster, both the γ Cassiopeiae nebulae (IC 59, reflection and IC 63, emission) as well as the open clusters M103, NGC 663 (Caldwell 10) and NGC 654. Finally, by extending the line further, one can find the famous Heart and Soul Nebulae. Lastly, the Sailboat Cluster (NGC 225) can be found west of Navi while Caroline’s Rose, an open cluster, (NGC 7789) can be found north-west of Caph.
