Our understanding of heavy element production in supernovae, exploding stars way beyond our solar system, may need to change following some discoveries we have made looking not to the skies, but deep under…

While the Mars Rovers and the Rosetta spacecraft will continue to make headlines in 2015, the stage is set for the solar system’s next great mission – the Pluto-bound New Horizons. Discovered in 1930…
Looking west after sunset on Friday September 26, the thin waxing crescent moon forms a triangle with Mercury and Spica, the brightest star in the constellation of Virgo. You can see how far Mercury has…
What makes our sun shine has been a mystery for most of human history. Given our sun is a star and stars are suns, explaining the source of the sun’s energy would help us understand why stars shine. An…
Take a look at the moon and it isn’t hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on…
Without the sun, there would be no Earth – but amazingly, we don’t know the finer details about the prenatal history of our sun, where it was born and if other stars in our galaxy share a similar history…
On August 6, millions of miles away from Earth, the firing of a rocket thruster signalled the end of a decade-long journey by a European spacecraft to reach its ultimate target – a comet. The spacecraft…
New observations of a youthful binary star system, reported today in the journal Nature, may help to explain one of exoplanetary science’s greatest unanswered questions – the peculiar orbits of so many…
In June, the popular press went wild. A planet had been discovered that was so much like Earth it was heralded as our best bet for supporting life. Positioned 16 light years away, Gliese (or GJ) 832c was…
NASA revealed today that the iconic Great Red Spot on Jupiter has shrunk to its smallest size ever – and astronomers have no idea why. The Great Red Spot is a giant anticyclone storm that has been raging…
An ocean of water has been found underneath the icy crust of Enceladus, Saturn’s sixth largest moon, according to observations of the Cassini spacecraft published in Science today. This result has come…
Finding liquid water on a celestial body within the solar system is exciting. The only thing that is probably more exciting is finding an ocean full of it. Today such news comes via Cassini, which has…
In a surprise discovery two rings have been found around the remote asteroid Chariklo, which lies more than a billion kilometres from Earth. This is the first time rings have been discovered around an…
A new, planet-like body has been found on the outer edges of the solar system. This object, called 2012VP113, is the second body of its class found since the identification of the dwarf planet Sedna in…
Comet ISON’s fate has left many sad. For the public, the comet could have made for a spectacular view in December. For scientists, it would have been a chance to learn more about these mysterious bodies…
Following India’s maiden Mars probe launch earlier in the month, last week saw the successful launch of the Martian Atmospheres and Volatiles Evolution mission, or MAVEN for short. With the second spacecraft…
While research suggests that Jupiter’s Great Red Spot should have disappeared by now due to fluid dynamics, a new study has…
A megavolcano found at the bottom of the Pacific Ocean is being reported as the largest single volcano on Earth. Tamu Massif, as the megavolcano is called, may be as voluminous as Olympus Mons on Mars…
You may have read the sun’s magnetic field is heading for a change in field polarity - meaning it will flip upside down - and could have ripple effects throughout the entire solar system. So what does…
CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, show that the planet Nibiru doesn’t…
