Cosmic Rays and Muons
Cosmic rays are hitting the atmosphere constantly. One of the products of the collisions is muons, and we can detect muons on the surface of the Earth to learn about the cosmic rays.

NGC6025 is an beautiful open cluster close to Beta Trianguli Australis in Triangulum Australe. Visible with binoculars and great in a telescope, well worth a look.
Star cluster and nebulae survey lists and astronomy observation catalogues are essential for finding cool things to look at or photograph. Imagine seeing a neat
We often give the Moon magical properties it simply does not have. The amount of illumination it provides changes and that’s about it.
Images of objects in space are often coloured to help astronomers work out what’s going on. This post looks at what we can work out.
This post explores the star Sirius A and its companion white dwarf, Sirius B. Discovered in 1862, Sirius B is a dense remnant of a larger star. The post discusses mass transfer between the two stars and explains the formation of white dwarfs. Sirius B’s density, surface temperature, and estimated age of 150 million years are also highlighted.
Recently published research has demonstrated that the expansion of the universe and black holes may be linked.
Stardate South Island was held 17-19 Feb 2023 at Staveley, near Christchurch. It was a fantastic weekend and you can read all about it here.
Venus doesn’t capture a lot of press time as it’s often overshadowed by the more hospitable Mars and the more photogenic planets of Saturn and Jupiter. It’s not all quiet around Venus, as JAXA has Akatsuki orbiting Earth’s twin and sending back some great images and building our understanding of Venus.
We got AI to describe Einstein’s theory of general relativity, and the results are pretty good. We also got some AI images created.
Cool things to look at in the May night sky. We describe 5 of our favourite ones, you may not have seen all of them before.
We run public stargazing sessions from an amazing dark sky location between Martinborough and Carterton in Wairarapa and we thought it would be helpful to cover what we do on our stargazing sessions.
Mapping of the night sky rests on some common features that enable the basis of a coordinate system. These include the Celestial Sphere, the Ecliptic and the Equinoxes.
The app we use to navigate around the night sky is SkySafari 7 Pro. Developed by Simulation Curriculum Corp, this app is a great way to learn about stars, planets and deep sky objects.
We can find out the age of a star cluster by plotting the stars on a graph called a Hertzsprung-Russell diagram.
Life needs CHNOPS, the six essential elements Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulphur. Curiosity found them on ancient Mars, but a new study shows Earth was born without them. Only a lucky impact with Theia made our world habitable. In contrast, Venus never stood a chance. Meet the three planetary siblings and discover why only Earth became a cradle for life.
Mars’s mantle contains ancient fragments up to 4km wide from its formation—preserved like geological fossils from the planet’s violent early history.
