Space Pebbles And Rocks Played A Pivotal Role In A Giant Planet’s Formation
Scientists analysing an ultra-hot giant planet believe it was formed by absorbing lightweight gases like methane evaporating from tiny space pebbles, whilst being bombarded with large rocky objects.

A New Way To Identify Liquid Water On Exoplanets
Scientists have devised a new way to identify habitable planets and potentially inhabited planets, by comparing the amount of carbon dioxide in their atmosphere, to neighbouring planets.
![Planets capable of supporting high O2 concentrations and, hence, technological civilizations. This figure shows the likely composition of planetary atmospheres based on mass and equilibrium temperature. For planets whose temperature and mass would lead to primarily CO2/N2/H2O atmospheres, high oxygen levels require a biological origin, i.e. photosynthesis. For higher equilibrium temperatures, high O2 levels can occur via the runaway greenhouse effect and the photolysis of water vapor at high altitudes.
