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...

DART is the mission based on the Hollywood blockbuster Armageddon. You know, the movie where the oil drillers are trained to go to space because there couldn’t possibly be an astronaut capable of being trained to be an oil driller. Anyway, if you think Michael Bay’s explosions are over the top, well...

We have rovers on Mars. Perseverance (or Percy, if you're on nickname terms) landed there just a few weeks ago to join Curiosity. And don't forget about Spirit and Opportunity (or Oppy, if you like) which also spent years traversing the Martian wastelands. Then just yesterday we saw the...

Here's a brief history on our understanding of black holes. In 1783 John Michell had a thought. Now that in itself was not unusual, as Michell was a philosopher, and someone whose thoughts were purportedly generations ahead of his contemporaries. What was unusual was that Michell began to think ab...
