Aspiration vs delivery: the long road to the Square Kilometre Array

The Square Kilometre Array (SKA) radio telescope has been on the cards since the early 1990s. It took until May of last year to find out where it will be built – in South Africa, Australia and New Zealand…
It’s long been suspected that Mercury’s poles are home to water ice. That speculation has now been confirmed. NASA

Water ice found on Mercury – has the ‘heavy metal’ planet lost its edge?

Whenever I’m telling students or people at conferences about Mercury, I always describe it as the “heavy metal” planet. Many things on this closest planet to the sun are extreme, from its 88-Earth-day…
The explosion of a super-luminous supernovae can emit as much light as our sun will in 10 billion years. Rampant.Gaffer

Super-luminous supernovae: seriously worth the superlatives

Supernovae are the brilliant, explosive deaths of stars. For a short time, these explosions can outshine an entire galaxy containing billions of stars. A recently discovered rare class of supernovae, termed…

Alpha Centauri exoplanet is the closest ever – how was it found?

Earlier this week, a Swiss-based team searching for planets outside our solar system (exoplanets) published a paper in Nature announcing the detection of an Earth-mass planet orbiting the star Alpha Centauri…
Things may not be as they’d previously seemed regarding the moon’s formation. NASA/JPL-Caltech

Was the moon formed by a planetary hit-and-run?

New research published in the planetary science journal Icarus, shows the moon may have been formed by a glancing collision with an “impactor” in the violent days of the early solar system. Contrary to…

Scientists find evidence of first ‘middleweight’ black hole

Explosive outbursts of super-hot gas in a galaxy 300 million light-years away have provided evidence of the first known “middleweight” black hole, according to scientists who observed the plasma jets with…
There’s far more to the night sky than the human eye can see. Joseph Dsilva

Explainer: radio astronomy

Humans have always had a deep affinity with the night sky. Over millennia the stars have guided us in our travels, provided a grand canvas for the great stories of mythology and invoked a sense of wonder…
