Daylight Come & Me Wanna Go Home*
The Big Picture:
NASA Langley researchers using the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite--a joint venture between NASA and the French space agency, Centre National d'Etudes Spatiales--recently learned something new about tiny squid and krill. Turns out those little creatures swim from the bottom of the ocean's depths to the surface to feed at night, returning home before sunrise. This means they conduct the longest migration of all animals on Earth.
The researchers also confirmed that CALIPSO's laser can penetrate the ocean's surface as far down as 200 meters (more than 65 feet) deep. So yeah.
