Using the Gran Telescopio Canarias (GTC), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have discovered a new extremely r-process-enhanced star in the Milky Way's thin disk. The finding was reported ...
The sun warms the Earth, making it habitable for people and animals. But that's not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the sun, is over a hundred times ...
