It's here. I’ve been harping on about this for a while now. I was so looking forward to it that one of my 2024 things to look forward to was that we'd be one year closer to first light. I'm talking about the Vera C. Rubin Observatory of course, and it has not disappointed. The first images, commis...

I’m fascinated by cosmology. What's not to love? It's the science of the origin and evolution of the universe and its ultimate fate. And the great thing is you can kind of figure a lot of it out by assuming the Big Bang happened and just working forward from there. One of the bits of evidence...

Titan is an interesting place. It's the largest moon of Saturn, bigger than our Moon and bigger even than the planet Mercury. It's also the only place besides Earth in the solar system with a dense atmosphere and standing bodies of liquid on its surface. Yes, Titan has rivers, lakes, and seas which...

In the outer solar system, beyond all the planets, there’s a lot of stuff. Small rocky and icy objects orbit the sun at enormous distances. But strangely there’s a group of these objects that seem to be clustered together. Now, the use of the word 'clustered' might imply that these objects are close...

Psyche is the mission to the asteroid 16 Psyche – a piece of space rock that is supposedly worth $100k quadrillion. Or, depending which media report you read today, it might be a billion quadrillion dollars, or even a trillion quadrillion dollars. At this point these numbers don’t even mean anyth...

Nuke Mars. You’ve probably heard about this, or maybe you have the t-shirt. The idea is simple. Mars has a cold, thin atmosphere that doesn’t support liquid water on its surface. You might think this is a non-problem not looking for a solution, but there is a segment of society intent on moving to M...

Osiris-Rex travelled around 6-billion km to get to asteroid Bennu, pick up some samples, and get them back to Earth. Now, you won’t often see people more excited by dirt, but this is dirt from another planet – which as a consequence of being other-worldly is rather rare on Earth. And it might jus...

The hybrid solar eclipse in Exmouth a couple of weeks ago was a pretty rare event, but to the surprise of no-one it was predicted with more-or-less perfect accuracy (cause, science). But it wasn’t always that way – actually, it was only a few hundred years ago that Halley (the comet guy) made the fi...

The post office got a bad rap during COVID, but I’m not sure too many people want their mail delivered by rocket. Regardless, it seemed like a good idea to Heinrich von Kleist who was going to use fixed artillery batteries to fire letter-filled shells to speed up delivery of the mail. This was in th...
Being almost the holidays, this might be a good time to talk about space tourism. Let’s ignore the advertising of well-known rocket launch companies and...
