A Variable Sentinel (Orchithemis pulcherrima) spotted at the Rail Corridor, Singapore, on 20 July 2021.

It took a while before I recognized it as a Variable Sentinel, since its body colours are variable. It has to be recognized more from its body shape.

Speech in Parliament by the Singapore Education Minister on the recent incident where a 16-year-old student was arrested for the murder of a fellow 13-year-old student, a shocking incident to happen in a school in Singapore.


M27, the Dumbbell nebula was the first planetary nebula discovered, by Charles Messier in 1764; though it would take until the 1780's for William Herschel to coin the term planetary nebula; and until the 1950's to figure out what they were.

Grey Fantail as seen from my veranda on the weekend. These delightful little birds catch insects on the wing and very active.
They also, as their name suggests, fan their tales for various reasons, sometimes to display a warning, sometimes in courting, and I suspect sometimes because they just want to look fabulous.

Heard a rapid rat-tat-tat racket while walking the mangrove boardwalk at Pasir Ris Park, Singapore, and traced it to this Laced Woodpecker (Picus vittatus) on 25 July 2021. It stayed there for some time, giving everybody a view of it.

The Laced Woodpecker is an uncommon resident bird.

"Ravidasvir hydrochloride, available as Ravida Tablet 200mg, had been given conditional approval by the Malaysian Drug Control Authority on Jun 4. Malaysia was the first country in the world to approve its use.

Manage to spot the Buffy Fish-Owl (Ketupa ketupu) found at Pasir Ris Park, Singapore, on 25 July 2021. It was high up on a tree. Even then, it looked quite big, and it has those intimidating claws

This bird is a generalist eater that also hunts fish, crabs, frogs reptiles and birds.

RIP. :-(

"John Carlos Baez @johncarlosbaez

Steven Weinberg died!

For all the talk of unification, there are few examples. Newton unified terrestrial and celestial gravity - apples and planets. Maxwell unified electricity and magnetism. Weinberg, Glashow and Salam unified electromagnetism and the weak force."

You can see unexpected things in some corners of Singapore. For example, Kin Yan Agrotech Pte Ltd, near Sungei Buloh Wetland Reserve, has a dragon model at their entrance. 🙂

A Scaly-breasted Munia (Lonchura punctulata) spotted at the Rail Corridor, Singapore, on 20 July 2021. I scared it away accidentally while trying to take photos of another creature. But when I moved away, it came back to continue feeding on some grass seeds, letting me take shots of it too.

The Scaly-breasted Munia is a common bird that is mainly a seed-eater and usually gathers in groups.

"[T]here’s intriguing evidence that a planet orbiting a nearby star may have the raw materials to build a moon, and one or more moons may be forming there right now. New (and extremely cool) observations confirm earlier ones that the planet is surrounded by a disk of dust with enough mass to make several moons the size of our own Moon."


"A trio of papers published Thursday in the journal Science, using data InSight has collected, reveals the red planet to be something like a colossal candy treat imagined by a ravenous deity. Its crust is split into two or three layers of volcanic chocolate. The mantle below has a surprisingly sizable and rigid toffee-like filling. And the planet’s core is surprisingly light — less nougaty center, more syrupy heart."


A pair of Ornate Coraltail (Ceriagrion cerinorubellum) spotted at the Rail Corridor, Singapore, on 20 July 2021. The female was laying eggs in the water, while the male was holding on to her.

Ornate Coraltail are common damselflies. But they are small and can be hard to spot.
