Author Interview with Professor Lisa Harvey-Smith
I have always had a fascination with the night sky, which blossomed
into a wonderful career in astronomy. Aside from my research though, one of the
most energising parts of my job has always been visiting schools and talking to
kids about space. They are always so excited and enthusiastic and the questions
they ask are so creative! I knew that I needed to create a book just for
them.
When I was a child, it was really the beauty of the stars
that first captured my imagination. My Dad and I used to go out somewhere
really dark and just take it all in. After a while though, I had questions
running though my head like, “How many stars are there?”, “How big is the
universe?”, “Is there other life out there?”... and the list goes on. So, I
began reading books about astronomy and I was enthralled by this amazing new
window on our universe.
*Astronauts age more slowly in space than they do on Earth,
ever so slightly! That's because the Earth's gravity bends our universe and
makes time pass more slowly. It's called 'time dilation'. Weird or what?!
*If you got too close to a black hole, your entire body
would be stretched by the enormous gravitational forces and you'd become 'human
spaghetti'.
*Ever wondered why the sky is blue? It's because the light
from the Sun is made up of all the colours of the rainbow. As the sunlight hits
our atmosphere, it is scattered across the sky by tiny particles of oxygen,
nitrogen and carbon dioxide that make up the air. These particles act as
millions of tiny mirrors. Blue light is scattered from these particles more
easily than red light, so that is why the sky appears blue.
*Shooting stars are not stars at all. They are actually tiny
specks of space dust that crash through our atmosphere as we orbit the Sun. The
bits of space dust rub against the air and heat up, reaching a temperature of
1000 degrees and burn up, creating bright streaks of light in the
sky.
*Our Sun is a gigantic ball of gas. Tiny particles crash
together in its middle, creating a nuclear furnace that burns at a
temperature of 15 million degrees. Four million tonnes of the Sun's gas is
burned into heat and light EVERY SINGLE SECOND!
I would have to say that seeing the first pictures from the
gigantic telescope I helped to build in remote Western Australia was a real
highlight for me. It's part of a global mega-science project involving more
than 10 countries and I had worked on the project for seven years before we got
any results. After all that time, seeing those first images of distant galaxies
was a real highlight for me. Also, on a personal note, touring Australia
with Buzz Aldrin, the Apollo 11 astronaut who first set foot on the Moon with
Neil Armstrong in 1969 was a real highlight for me. Talking with someone who
has explored another world and sharing their experiences, it's just such an
incredible feeling.
Since I was about 15, I have dreamed of being the first
Woman to go to the Moon. It won't be me, but I'm very excited that NASA has
pledged to send the first woman to the moon by 2024.
What do you think still needs to be discovered about space, the galaxies or the night sky?
The great thing about our universe is that there is so much still to discover! For example, we only understand what 4% of space is made from. The other 96% is completely out of our grasp. We don't know how the universe will end, or if it will ever end at all. We are yet to learn how life began on Earth and whether we are alone in the universe. So many mysteries are yet to explore.
Please describe a day in the life of an astrophysicist
Astrophysics is a wonderful pursuit. On a typical day I
might work with a team of scientists on a scientific problem or make pictures
of the sky from information I have gathered from telescopes. I'd read the
latest astronomy research and see what other people are discovering, to get new
ideas. I might travel to a conference or a telescope in a far-flung region of
the world or share my results by writing a scientific report or speaking to
fellow scientists about my latest discovery. Then I might work with students
and help the next generation of scientists learn and grow in their
discoveries.
What do you think kids will get most out of reading your new book?
Under the Stars: Astrophysics for Bedtime is all about
cultivating a sense of wonder and exploration in young children. The
illustrations are designed so that every child can see a role model who looks
like them. It is so important for girls and boys to engage enthusiastically in
science, technology, engineering and maths subjects so that we can build a
future designed by everyone that serves the needs of society.
Parents get an opportunity to read fascinating stories about
space to their children and help stimulate their curiosity at the same time. As
kids get older, they will get a bit of peace and quiet as children get
engrossed in reading the book themselves! Older primary-aged kids will love
reading the stories again and again, each time learning something new. And
don't tell the kids - but this book is also for the grown-ups too! You can have
a sneaky read once the littlies have gone to sleep. Learning is a life-long joy
after all.
Please feel free to share any amazing stories or anecdotes about writing this book if you have any!
Writing Under the Stars was a labour of love. Since I work
full-time, I did my writing at night, dreaming up stories and crafting the
book from my bed. I think that writing at night helped create the dreamy
'astrophysics for bedtime' vibe of the book.
