(Inside Science) -- Astronomers spent February uncovering ordinary things in unexpected places. They found X-ray sources strewn across the Whirlpool galaxy, observed a salty stellar atmosphere light years away, and even snapped pictures of clay as close as Mars. This month's variety of illustrations and photos show that discoveries in astronomy, like the universe, are ever-expanding.
