Education Around Earth – Ocean Literacy for a Blue Planet

Cropped image of children playing with seaweed at a pool.Ocean and aquatic sciences remain among the most underrepresented disciplines in K–12 educational curricula. Rarely taught at any level, concepts about the ocean, the coasts or the Great Lakes infrequently appear in K–12 curriculum materials, textbooks, assessments or standards. The National Oceanic and Atmospheric Administration (NOAA) is working to help educators bring ocean sciences into the classroom.

Large X-class Flare Erupts on the Sun

Large X-class Flare Erupts on the Sun

On Jan. 27, 2012, a large X-class flare erupted from an active region near the solar west limb. X-class flares are the most powerful of all solar events. Seen here is an image of the flare captured by the X-ray telescope on Hinode. This image shows an emission from plasma heated to greater than eight million degrees during the energy release process of the flare. Image Credit: JAXA/Hinode
