Looking up at the nighttime sky with a telescope is an irreplaceable experience.

The humble telescope is not an instrument that is featured in the media headlines. But it is an invention which has revolutionised our understanding of the planets, the galaxies, the stars and the universe. Getting a telescope as a child was an outstanding experience; looking up at the nighttime sky piqued my curiosity about what makes up outer space.
So here is an idea; how about introducing telescopes in school. No, not every student wants to be an astronomer. No, not every child aspires to be a scientist. However, a telescope in school introduces students to the techniques used, and information gathered by, astronomers and scientists.
Yes, every student now has access to a mobile device or a computer. The ubiquity of the internet has made information about the stars, planets and galaxies easily accessible. You can download the astronomy picture of the day, and that sparks wonder and admiration of the cosmic realm.
Of course telescopes, like every other scientific device, has undergone massive technological changes over the years. Telescopes are light collectors, and we view space objects in the visible light spectrum.
They have become updated to observe and collect data from the nonvisible bands of the electromagnetic spectrum. When connected to a computer, a telescope becomes a data processor. Now there are telescopes that, for instance, observe the X-ray portion of the EM spectrum. Ground-based telescopes, while highly sophisticated, are now supplemented by space-based telescopes.
The James Webb Space Telescope is one of a number deployed to outer space. The Earth’s atmosphere and the artificial electric light of urban environments interfere with the quality of Earth-bound telescopes.
Currently, telescopes are so sophisticated, their capabilities are astonishing. Consider the following; astronomers have made a 3D map of the atmosphere of Uranus.
Ok, okay – let’s get all the juvenile jokes out of the way, about Uranus and gas. Get it off your chest – the infantile urge to make jokes about the name Uranus and butts. Ok, is that over? Fine.
The planet, correctly pronounced ‘Yoor-an-us’, is named after the Ancient Greek god Ouranos. I have previously written about Uranus here. The first planet to be discovered by telescope, in 1781, Uranus has intrigued astronomers since then. Its atmosphere, thought to be bland and uneventful, is anything but that.
Composed mostly of hydrogen, the upper atmosphere of Uranus has been mapped by astronomers using the James Webb telescope. Learning more about the atmosphere of another planet helps us to understand planetary formation is its early stages. The magnetic field is also bizarre; rather than having a stable dipole structure similar to the Earth’s magnetosphere, Uranus’ magnetic field is unstable, much like a flailing jellyfish.
In Australia, we have a very narrow, parochial and opportunistic view of science education. The question, so after you have stated the science courses you are taking, is ‘so what can you do with that?’ We view education as a kind of garden implement; we learn only so we can ‘do something with it’, like a lawn mower or whipper snipper.
Now it is not wrong to think about the practical application of science courses. But if you study a subject only because you want to ‘do something with it’, then your education will be limited and confining. Education is a lifelong journey, and each topic has its own merits.
When I signed up for high school geology, I inevitably faced the question ‘do you want to be a geologist?’ My answer was no, not necessarily. So why did I study that course? Because every branch of science is endlessly fascinating, and rewarding in its own right.
Let us for the moment accept that I should be ‘doing something’ with a subject after studying it. Well, I can say that I am definitely doing something with the geology course. No, I am not a geologist, but I am applying what I learned in that subject to life today.
In 1986, the first lesson of geology class for the year was dedicated to examining the Challenger Space Shuttle disaster. This was the topic that we addressed in class, first lesson back from the summer holidays. We examined, as much as we could given the availability of information regarding that tragedy, the causes and consequences of the disaster.
Here we are, 40 years later, and the Challenger disaster is still a topic of investigative pieces, such as this one on the ABC. It remains a pivotal disaster in the history of the US space programme. I do not wish to disrespect or insult the memory of the seven dead astronauts, but let us observe the following.
In 1988, barely two years after the Challenger catastrophe, the Soviet space programme Interkosmos, successfully launched a team of cosmonauts which included Abdul Ahad Momand, an Afghan pilot and that nation’s first (and so far only) cosmonaut. The Interkosmos programme recruited and trained cosmonauts from non-aligned and Eastern bloc nations into the Soviet space programme.
Science education is one of those things where, you do not notice it until it is gone. With the Trump administration’s cutbacks to science programmes, including NASA, scientific education is under threat. The ability of future generations to tackle the hard scientific questions will be severely undermined if we do not invest now in building the required knowledge capital of students.
