What to see in the night sky – a focus on Canis Major
The stars around Sirius make up the constellation of Canis Major which has some really nice open clusters to view through binoculars or a telescope.

The Stardate in the South Island over the weekend was a fantastic opportunity to learn about some objects that we haven’t seen before.
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.
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.
