The Moon

Posted on Wednesday, 24 July, 2013Sunday, 20 August, 2017 by Zheluo Cai

Last night, we had a Full Moon. We will always see only one side of the Moon due to its synchronous rotational mode (takes 27 days to obit the Earth) and angle between the Earth and our Sun. As it is the closest astronomical object (circumference of 10,917 km) to Earth (384,400 km away), and the only natural satellite of the Earth, its terrain can be appreciated on a clear night. Apart from the Earth, it is probably the most studied in terms of cosmic objects. Worth taking a closer look during each of its phases the next time round. It’s beautiful!

ASTRONOMY PHOTO OF THE DAY: The Red Rectangle Nebula. Credit: ESA, Hubble, NASA. The Red Rectangle nebula lies 2,300 light years towards the constellation of the Unicorn (Monoceros). At its centre is an aging binary star system that powers the nebula. The unusual shape is likely due to a thick dust torus which pinches the otherwise spherical outflow into tip-touching cone shapes, with the outflow occurring in fits and starts. In a few million years, as one of the central stars becomes further depleted of nuclear fuel, it will likely bloom into a planetary nebula.

THE FLAG OF PORTUGAL: The flag is a rectangular bicolour with a field unevenly divided into green on the hoist, and red on the fly. The lesser version of the national coat of arms (i.e. armillary sphere and Portuguese shield) is centred over the colour boundary at equal distance from the upper and lower edges. On 30 June 1911, less than a year after the downfall of the constitutional monarchy, this design was officially adopted.
