Condensing dust and gas light up newborn stars in a picture of Messier 8, aka the Lagoon Nebula, released on April 19 by the European Southern Observatory.
About a hundred light-years across, the stellar nursery is among the few such nebulae visible to the naked eye. It boasts a number of huge, hot stars that are sculpting the clouds with their strong radiation.

The star-forming region known as IC 1795 lights up the bottom right corner of a picture from NASA’s Wide-field Infrared Survey Explorer (WISE) telescope released on April 16.
The region, part of the Perseus arm of our Milky Way galaxy, appears mostly dark in visible light. But the gases and dust light up in infrared. The colors in this picture represent different infrared wavelengths coming from the dust cloud and the hot, young stars inside.
