Jonathan Amos of BBC News reports that MIT researchers have identified a large rectangular feature on the moon. “The 2,500km-wide structure is believed to be the remains of old rift valleys that later became filled with lava,” writes Amos. 

Washington Post reporter Rachel Feltman writes that researchers have found evidence that the moon’s basin was formed by magma flows. "For anyone who's ever looked up at the moon and wondered why it has this pattern on its surface — now we have an answer,” says MIT Vice President for Research Maria Zuber.
