Theories of the formation and early evolution of planetary systems postulate that planets are born in circumstellar disks, and undergo radial migration during and after dissipation of the dust and gas disk from which they formed. The precise ages of meteorites indicate that planetesimals—the building blocks of planets—are produced within the first million years of a star’s life. Fully formed planets are frequently detected...

A map of the most vulnerable places on the planet
Enlarge / Global snapshot of the Vegetation Sensitivity Index (VSI), which measures environmental sensitivity to a changing climate, using satellite data gathered between 2000-2013 at 5km resolution. Areas in green are covered in vegetation that is the least sensitive to changes. Areas in red show the highest sensitivity. Grey areas are barren land or...

Planet X? Probably not, but ALMA telescope array’s readings stir up debate
An array of radio telescopes in Chile has picked up weird readings that appear to be coming from far-out objects – and that’s sparked a debate over whether they’re previously undetected worlds on the edge of our solar system, brown dwarfs,...
