The Sun is currently middle-aged, having celebrated its 4,568,000,000th birthday at some point in the last million years.
In five or seven billion years time, the Sun's life will come to an end. And it will be really spectacular - if you're watching from far enough away.

Providing security in the blockchain would convert into a degree of predictability in the technology. If this was shown to work in the long term, it would also create trust.

Australia sends 20 million tonnes of garbage to landfill every year. With thousands of sites across the nation, it's hard to track exactly how many there are, where they are, and what's filling them.
Sweden performs in the 2017 Eurovision grand final.
As always, Eurovision 2017 blended pop and politics. Russia was missing from the Ukrainian-hosted contest, and the UK had healing words, post Brexit.
Almost every star has planets – so there are more planets in our galaxy than there are stars.

Plants on other planets are bound to be even weirder than the strangest ones we find on Earth – if they even exist.
Vouchers give parents more choice over schools.
There is no evidence to suggest that vouchers are simpler, fairer and more transparent than current funding models.
This illustration shows Cassini diving through geyser plumes on Saturn’s the ocean world
moon of Enceladus.
Earth is a relatively dry planet compared to some of the other ocean worlds in our Solar system. Life needs water so what about life on these other places?
The languages children learn in school might not be the most useful for their future.
There is usually a historical reason why schools teach certain languages. But as new economies emerge, such languages may no longer be the best ones to learn.
The most reliable way to find the best school for your child is to visit and find out about its philosophy and programs.
My School data does not show the quality of teaching, and school comparisons and rankings can be misleading.
Learning a language in a classroom is best for early teenagers.
The classroom setting is better for early teenagers, while self-guided language learning is better for adults.
An artist’s concept of what it could look like on the surface of one of the exoplanets of TRAPPIST-1.
Several of the newly-discovered exoplanets orbiting a small star appear to be locked in an intricate dance that hints at how such planetary systems can form.
It’s important to get the research across to and understood by decision-makers.
Research comes with risk and uncertainty so getting the right message across to the people who matter can be a challenge for scientists. A new plan out today hopes to change that.
Patience can be rewarded as with this composite of the 2016 Geminids meteor shower, seen over Mt Teide volcano on the Canary Islands, off Spain.
2017 is looking to be a spectacular year for meteor showers. So here's what to look out for in both the northern and southern skies.
Australia has slipped further down the international rankings in maths, science and reading.
Rather than leaping to conclusions about a failing education system, we need to look at what the data tells us about student performance at a state level to help us make more informed decisions.
Untangling the history of the Milky Way.
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
Younger farmers are more willing to take up the opportunities presented by outside investment, a new study shows.
Young farmers are more open to outside investment and ownership of the family farm, than older farmers, new research shows.
Networking online might not be so good for your “social capital” overall.
Spending lots of time on the internet might be good for getting what you want in the short term but it might not work in the long term.

Australians send about 4 million tonnes of food waste to landfill each year – but what if we could use it for other purposes?
An artist’s impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to our solar system.
Astronomers have found an Earth-like planet orbiting our nearest neighbour, the red dwarf star Proxima Centauri. So any chance that planet may be habitable?
The ruddy hue of our moon in a total lunar eclipse.
The red hue of the moon during a total lunar eclipse gives astronomers at cue on how to find out more about the planets being discovered around other stars.
