We visited the Mars Yard at the Museum of Applied Arts and Sciences in Sydney a few weeks ago and had a great time at this fantastic facility that is doing very important work.
NASA’s Parker Solar Probe is set for launch on 31 July to begin it’s journey to the Sun’s corona to help us understand more about the solar wind and why the corona is so hot.
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.
