NASA just confirmed that asteroid Oumuamua broke apart, and a smaller meteorite was injected into Earth orbit! Remains found at the impact site near San Francisco included a small capsule. The capsule, or device continuously transmits the following message, oddly enough obtained from Earth.

How burning Forests melt Ice Sheets

Forest fires can melt glaciers thousands of miles away by changing the colour of the ice – all thanks to a heavy little particle called black carbon. This strange story of smoke, dust and algae looks at the lesser-known half of a positive feedback loop: not only does climate change make fires bigger and badder,…

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ
