There are so many number systems! The ones you know now were developed over centuries but we are still making up more now.
The Romans were great engineers but they had a terrible number system. It didn’t even have zero.
The butterfly orchid grows beautifully.

The blotched butterfly orchid (Sarcochilus weinthalii) looks fairly unremarkable when it’s not flowering, generally resembling the far more common orange blossom orchid. But when it flowers, it is exquisite…
Astrophysicist Matt Agnew is looking for love on the Bachelor Australia.
Matt Agnew is on the hunt for love as star of the new Bachelor Australia series. But whoever he picks (and he already has, apparently) will have to compete with TESS. So who, or what, is TESS?
Clara, keen as ever for some well-deserved attention.
It can be tough to train a dog – but mainly because humans are even more prone to distraction and inconsistency than our canine companions. Wearable technology might help us be a bit more consistent.
When it was young, the Sun spun fast – very fast. It would do one rotation in a just one or two Earth days.
Yes, the Sun absolutely spins. In fact, everything in the universe spins. Some things spin faster than the Sun, some are slower and some things spin 'backwards'.
Today, we’re asking two astrophysicists and a planetary scientist: what’s the likelihood we’ll be living on Mars or the Moon in future?
What’s the next ‘giant leap’ for humankind in space? We asked 3 space experts.

What's the next thing that will blow us away or bring us together the way the Moon landing did in 1969? Moon mining? Alien contact? Retirement on Mars? Three space experts share their predictions.
Public libraries can use their status as community hubs to engage the public in scenario planning for the future.
We commonly think of libraries as repositories of knowledge accumulated over centuries. But the public library also connects people in ways that can enable communities to plan for their future.
The size of the Moon can be deceptive when viewed from Earth.
Just 12 people have walked on the Moon and they'll know better than anyone just how big (or small) the place is. But we can make some comparisons with things on Earth to get a measure of the Moon.
People do live outside Earth – on the International Space Station! But humans have had to find a way to make the conditions there more like what we’re used to at home.

The short answer is yes, but it’s really, really difficult.
It’s true the Sun often looks orange, but it isn’t really orange. It is white.
The very hottest stars actually glow blue.
We found students who played chess didn’t show significant improvements in their standardised test scores.
Previous studies that explored whether chess improves children's cognitive abilities have had mixed results. We found playing chess wasn't linked to better standardised test scores.
The number of students studying Mandarin in Australian schools nearly doubled between 2008 and 2015.
Even if only 130 Australians of non-Chinese heritage can speak Mandarin fluently, there are many more if you count those of Chinese heritage. And a level of fluency is not the only measure of success.
Students with vision impairments should the same opportunities as their peers.
Interviews with students who have a vision impairment show they wish their teachers and friends knew more about them. Here are the four key messages they want to communicate.
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.
