(Phys.org)—Astronomers have spotted transient, transit-like dimming events of a young star named RIK-210 located some 472 light years away in the Upper Scorpius OB association. However, what puzzles the scientists is the ...
Many scientists believe the Earth was dry when it first formed, and that the building blocks for life on our planet—carbon, nitrogen and water—appeared only later as a result of collisions with other objects in our solar ...
