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.
From ancient climate changes caused by our solar system’s galactic road trip to NASA’s dishwasher-sized Moon explorer and Australia launching Vegemite into space, this month’s space roundup has it all. Plus, if you ever need to call ET, the 21 cm hydrogen signal might be your best bet! And did you know rogue planets aren’t necessarily kicked-out exiles? They might actually form on their own. 🚀🌍✨
There is real science that you can contribute to right now, just with a smart phone or computer and your brain. You don’t need a PHD in astrophysics or cosmology or anything else, just some pattern recognition skills and a desire to contribute to a better understanding of the universe.
Stars don’t last forever, it might seem like 10 billion years is almost forever but not every star lives as long as our Sun. This article covers what happens when stars die and shows some very awesome images from the European Space Observatory of the surface of some stars.
(And we can do something about it.)

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.
