Observing the planets and their apparent relative sizes
When observing the planets in astronomy it can be quite surprising to see the different sizes that appear in the eyepiece and how this can change over time.

The game changer for access to space will be humanity moving away from the use of chemical rockets to get into orbit. The disrupters to the space industry will be the ones that perfect the alternative technologies.
We had a great time showing heaps of students Jupiter and Saturn during a talk about Matariki at Government House.
Hayabusa2 is about to have a close up and personal experience with the asteroid Ryugu. In this mission the spacecraft will collect a bit of the asteroid and return to Earth.
Now that your telescope is all ready, take it outside and start viewing the night sky.
Using a telescope for the first time can be quite daunting. So it’s worth taking the time to get familiar with the telescope and the mount and all of the accessories, so that you can make the most of your time outside and don’t hurt yourself or your new expensive equipment.
New Horizons will make its next encounter on 1 January next year as it approaches the Kuiper Belt Object Ultima Thule, formerly known as 2014 MU69.
The Pleiades are a fascinating star cluster that is easily spotted not far from the Hyades cluster in Taurus and is visible in the Southern Hemisphere summer, Northern Hemisphere winter.
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.
