Astrophysics
Astrophysics explores how the Universe works. By combining physics, mathematics and astronomy, astrophysicists investigate stars, gravity, light, galaxies and the large-scale structure of the cosmos. Through observation, evidence and scientific models, astrophysics helps us understand how stars produce energy, how galaxies evolve and how the laws of physics shape the Universe around us.
These resources support senior students, teachers and curious learners exploring astronomy, astrophysics and Earth & Space Science through observation, scientific inquiry and advanced space science concepts aligned with the New Zealand curriculum.

This section explores astrophysics through real observations, scientific inquiry and advanced space science concepts designed to support curious learners, senior students and teachers exploring the deeper physical nature of the Universe.
How do we understand the Universe?
The universe is both unimaginably vast and somehow understandable by tiny conscious beings living on a small planet.
Astrophysics sits at a strange crossroads between awe and comprehension. It confronts us with scales, energies, and times beyond ordinary human experience — yet through mathematics, observation, and imagination, we can genuinely understand parts of it.

Black holes
Black holes fascinate people because they feel like nature pushing physics to its limits.

The origin of everything
Where did the universe come from? What was there before that?
cosmic scale and deep time
By the time you say “tick tock” you can go to the Moon and back if you travel at the speed of light.
Yet, the most exceptional idea of all…
The carbon in your cells,
the oxygen you breathe,
the iron in your blood,
the calcium in your bones—
all were forged inside stars.
We are literally made of stars
The universe evolved structures capable of becoming conscious and studying itself.

Astrophysics in Practice
In 2026, SpacewardBound NZ hosted students from across New Zealand for the national Astronomy and Astrophysics Olympiad training camp in Wairarapa. Through observation sessions, astrophysics workshops, and collaborative learning experiences, students explored advanced astronomy concepts while preparing for the international competition and engaging in scientific inquiry beyond the classroom.
