Pluto, Charon, and New Horizons

I am sharing this post that was done up by Gary on his blog, so that everyone who sees this can tune in to watch the flyby and closeup of Pluto tonight.

On 14 July 2015, at 7:49:59 PM Singapore time (11:49:59 UTC) NASA's New Horizons spacecraft will make its historic closest approach to the dwarf planet Pluto, the most distant solid object to be visited by a spacecraft.

Venus + Jupiter Conjunction

It was an awesome sight to behold! Yesterday evening, I managed to witness the conjunction of Jupiter and Venus at their closest as I met Dave and Ava when they held a sidewalk session at Bishan Park. Sadly, we only caught a glimpse of the pair when thick clouds started to roll in, even the Moon was obscured by the overcast. I could only count myself lucky, other people who came to Bishan Park with the expectation to see the spectacle were sorely disappointed. Well, that's astronomy on the highway of clouds.

This shot was taken at Bishan Park on the 30th of June 2015. The bigger and brighter dot is Venus, with its companion Jupiter at the top.
