In the absence of mathematical explanations, the universe would be irrational rather than unpredictable.
The dwarf planets in our Solar System are cold, dark, far away and full of surprises.
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Shrinking satellites are making it cheaper and more accessible to do science in space.
The future of Australia’s space efforts will hinge on coordination between defence, industry and universities.
