The discovery of tiny salt grains in a sample from an asteroid provides strong evidence that liquid water may be more common in the solar system than previously thought. Sodium chloride, better known as table salt, isn’t exactly the type of mineral that captures the imagination of scientists. However, a smattering of tiny salt crystals discovered in a sample from an asteroid has researchers at the University of Arizona Lunar and Planetary Laboratory excited, because these crystals can only have formed in the presence of liquid water.

Even more intriguing, according to the research team, is the fact that th...

Curtin University-led research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth.

The international team studied three tiny dust particles collected from the surface of ancient 500-metre-long rubble pile asteroid, Itokawa, returned to Earth by the Japanese Space Agency’s Hayabusa 1 probe.

The study’s results showed asteroid Itokawa, which is 2 million kilometres from Earth and around the size of Sydney Harbour Bridge, was hard to destroy and resistant to collision.
