Matt Dodds is an Amateur Astronomer and the Education Officer for the Sydney University node of ASTRO 3D. He has a keen passion for Astronomy and Science Education and connecting people with the night sky. Having spent the better part of the last decade as a High School Science Teacher, Matt excels at inspiring students to follow their passions, ask questions and pursue their goals in Science related fields. Matt can often be found travelling around the country, sharing the eyepiece of his telescopes with school groups or the general public. He also presents various workshops to teacher and student groups such as the basics of spectroscopy, the scale of the solar system and how to build a telescope. One his long drives around Australia he loves listening to Astronomy podcasts such as "Space Nuts", "Cosmic Vertigo" and the "Exocast". He is on both Instagram and Twitter @ScienceWithMat.

Dr Sarah Caddy is an observational astronomer who loves anything to do with new and innovative telescopes that allow us to observe the skies in surprising and unexpected ways.

Sarah is from the Melbourne Space Laboratory where the team is developing new space telescope missions to monitor space debris, and flying the Australian SpIRIT space telescope. The little satellite recently celebrated 500 days in orbit, and spends its time taking pictures of the Australian landscape from space and hunting for high energy bursts of light from merging black holes and neutron stars.

Sarah and her team at Australian Astronomical Optics Macquarie operate the Huntsman Telescope where her work has taken an interesting twist from observing at night, to broad daylight which allows the team to monitor the skies for satellites. It seems like every day more and more satellites are launched which has started to create "traffic jams" in space. By trading stars for satellites, the Huntsman team hopes to help monitor the whereabouts of satellites to keep all astronauts and spacecraft safe.

Dr Rowina Nathan is an astrophysicist at the Australian National University who studies the Universe using gravitational waves—tiny ripples in space and time caused by energetic events like black hole collisions. Her research focuses on understanding extreme objects like black holes and neutron stars, and on testing Einstein’s theory of gravity in new ways.

Alongside her research, Rowina is passionate about science communication and shares videos about space and physics online as PinkAstrophysicist, helping make complex ideas more accessible and inspiring the next generation of scientists.
