Witch Nebula Casts Starry Spell – NASA

This 2013 image taken by NASA’s Wide-Field Infrared Survey Explorer, or WISE, captures a nebula that looks like a witch screaming. Perhaps that imagined scream is a creation spell, for the Witch Hat nebula’s billowy clouds are a star nursery. We can see these clouds thanks to massive stars lighting them up; dust in the … Read more

Data From NASA’s WISE Used to Preview Lucy Mission’s Asteroid Dinkinesh – NASA

Researchers have utilized infrared survey data to refine the asteroid’s size and surface brightness in support of the Nov. 1 encounter by NASA’s Lucy mission. NASA’s Lucy mission will soon have its first asteroid encounter as the spacecraft travels through deep space en route to Jupiter’s orbit. But before the spacecraft passes 265 miles (425 … Read more
