The night sky is full of stars and some of the very brightest we see have some very interesting characteristics. Next time you’re looking at Sirius or Canopus you’ll be able to appreciate just how big they are compared to our very own star - the Sun.
Stellar evolution is a fascinating topic and what happens in the last phases of a star’s life is mind boggling. Some stars are so big that their collapsing core turns straight into a black hole that suppresses the supernova.
Venus doesn’t capture a lot of press time as it’s often overshadowed by the more hospitable Mars and the more photogenic planets of Saturn and Jupiter. It’s not all quiet around Venus, as JAXA has Akatsuki orbiting Earth’s twin and sending back some great images and building our understanding of Venus.

We are getting a better and better at understanding how planetary systems are formed. This article tracks the historic development of the heliocentric model and how that relates to understanding the formation of our own Solar System.
