One of the fireballs (highlighted by the red circle) captured over the Northern Territory.

Security cameras captured two separate fireballs over Australia this week. So what's responsible these bright flashes?
Searching for planets around nearby stars is like searching for a needle in a field of haystacks.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.
Thousands of Queensland beachgoers have been stung by bluebottle jellyfish in recent months.
Better public awareness about Australian jellyfish is vital, especially as many Aussies head to the beach for likely the last time this Easter.
Seberapa dekat posisi asteroid yang berpotensi berbahaya sebelum dapat terdeteksi?
Saat ini kita telah menemukan lebih banyak objek dekat Bumi, tapi tantangannya adalah mengidentifikasi benda yang berpotensi menabrak kita.
How close can a potentially dangerous asteroid get before it’s detected?
We're finding more near-Earth objects all the time, and the challenge is to identify those that could potentially hit us. So how come we missed one that caused a huge blast in December?
City clothes mark the wearer as being out of place in the country.
Your identity changes when you move house and, if that's to a different community, your clothes change along with you.
Again this year, the Closing the Gap report delivered disappointment.
There is little reason to think changes made to the Closing the Gap targets and partnerships with Aboriginal and Torres Strait Islander representatives will have much of an impact.
To make a success of moving home, to the country for example, it helps to be open to the ways a place will change you.
Think moving won't change you? You might want to rethink that. To feel 'at home' you need to accept the new place where you live as part of your changing identity.
Your tongue has special parts, bundled together as taste buds, that pick up flavour. But your other senses also help your brain work out how something tastes.
Your tongue, saliva and nose work together to help you taste your food.
An artist’s impression of Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone - the region around a star where liquid water, a requirement for life on Earth, could persist.
Life could exist in another solar system in a different part our galaxy. Or in another galaxy far away. We don't have the perfect technology yet to study such far away places but we're still trying.
The 2018 Geminids meteor shower recorded over two very cold hours on the slope of Mount Lütispitz, Switzerland.
Moonlight will spoil some of the big meteor showers this year, but still plenty of others to see. So here's your guide on when and where to look to catch nature's fireworks.

The comet 46P/Wirtanen is just 1.2km in size but it should be visible in the night sky this Saturday as it makes a close approach to Earth this year. And don't forget the Geminids meteor shower.
Uluru-Kata Tjuta: of 19 Australian World Heritage sites this is one of only two that recognise the values of ‘living’ Aboriginal culture.
Of 19 World Heritage sites across the country, only two, Kakadu and Uluru-Kata Tjuta, recognise the values of "living" Aboriginal culture. None of Australia's three sites inscribed purely for cultural values recognises Aboriginal people.
The South Pole Telescope and BICEP telescopes (pictured above) may discover clues that could teach us if there was something else ‘before’ the Big Bang.

Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.
How many times have you heard “get out of the way!” when someone is trying to change the channel?
Even the Voyager spacecraft are controlled remotely, 20 billion kilometres away. It takes 20 hours for instructions to travel from Earth to the spacecraft but we can do it -- using a remote.
An artist’s impression of the surface of the planet orbiting Barnard’s Star.
ESO - M. Kornmesser
The new planet is believed to be orbiting Barnard's Star, a red dwarf that's not visible to the naked eye but one of the closest stars to our Solar System.
Nobody knows for sure - but it’s possible.
There are probably more than a million planets in the universe for every single grain of sand on Earth. That's a lot of planets. My guess is that there probably is life elsewhere in the Universe.
The Sun is a star – but it’s not the only one.

There are lots of places where it's much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
The TV drama SeaChange had a huge public impact, which made the town where it was filmed, Barwon Heads on Victoria’s Bellarine Peninsula, a highly desirable destination.
We read about and watch other people moving to the coast or country and, in doing so, sometimes we're persuaded to join the seachangers and treechangers ourselves.
The community environment clearly has a large influence on child development, but exactly which factors are most important?
Research has started to identify the key factors in creating communities that promote good early childhood development.
