An asteroid on a collision course with Earth is inevitable. Astronomer Michael Lund explains how a new telescope under construction in Chile will become a vital tool for detecting objects that could devastate our planet.
Blast off.

Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
From moon landing to space arms race.

Trunp’s new policy could lead to the militarisation of outer space and the beginning of a new space arms race.

The first step to mining an asteroid is finding a suitable candidate. Scientists estimate there should be some ten nearby targets.

Large asteroids have hit Australia over many millions of years and the evidence is in the landscape, if you know where to look.
Don’t panic…yet.

Small asteroids can be hard to spot. But what kind of threat do they pose to the Earth?

‘Oumuamua is likely a relatively young interstellar visitor from a binary star system.

A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.

Having discovered an asteroid from outside the solar system for the first time, scientists are hoping there are more out there – illuminating the path to extrasolar worlds.

The mass extinction of the dinosaurs was down to the location of the asteroid’s impact and the kind of rocks it landed on.
It’s a bird… It’s a plane… No, it’s an object from another solar system! Astronomers have been scrambling to identify a mysterious object passing through our solar system at a speed of about 160,000 km/h. This NASA file image shows a simulation of asteroids passing the earth.

Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.

The mystery object seen moving through our Solar system shows the void between the stars is far from empty. So can we expect more interstellar visitors?

Researchers are looking at whether devastating asteroid strikes are predictable or random.
It’s happened before: why we need to plan for the next doomsday event that could wipe out much of life on Earth.

NASA says there are ten “potentially hazardous” asteroids close to Earth. Good reason to make sure we have a backup plan should any catastrophic event wipe of much of life on Earth.

Evidence is mounting that water came from within the Earth not from asteroids or comets.
The end was nigh.
