So you got your binoculars for Christmas, now what? If you live in the Southern Hemisphere then much awaits you. Same in the North, just I didn’t write about it here.

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.
