Does it orbit the Milky Way? Expert Q&A Additional resources Bibliography The Large Magellanic Cloud (LMC) is a dwarf galaxy that is close to the Milky Way. The LMC and its neighbor, the Small Magellanic Cloud (SMC), are so close to our galaxy that we can easily see individual ...
The scientists said that a shift toward wetter conditions, perhaps caused by natural shifts in the Earth’s orbit around the sun, led to growth of more trees starting about 2,000 years ago. The “findings suggest that rather than being rainforest hunter-gatherers, or large-scale forest ...
