This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1, and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches. The color range for this visualization is -7 cm to +7 cm (-2.76 inches to +2.76 inches), though measured data extends above and below 7cm(2.76 inches). This particular range was chosen to highlight variations in sea level change. Download the visualization: http://svs.gsfc.nasa.gov/cgi-bin/deta....

This winter, areas across the globe experienced a shift in rain patterns due to the natural weather phenomenon known as El Niño. New NASA visualizations of rainfall data show the various changes to California. According to the National Oceanic and Atmospheric Administration, El Niño was expected to produce wetter-than-average conditions from December 2015 to February 2016. Scientists refer to historical weather patterns and to look at trends of where precipitation normally occurs during El Niño events. Also, several factors—not just El Niño—can contribute to unusual weather pattern.

Re/code visits NASA's Silicon Valley research center, where a pair of startups are working together to democratize satellite data. Aquila Space is building a fleet of satellites while its partner Astro Digital is developing software tools that allow anyone to process and analyze the data. Among other things, the information could be used to help inform policy and responses for ecological disasters, including the droughts and wildfires plaguing California.

This timelapse video was made from images taken by ESA astronaut Alexander Gerst orbiting Earth on the International Space Station. The video is offered in Ultra High Definition, the highest available to consumers. Be sure to change the settings in YouTube if your computer or television can handle it for the full effect. The montage is made from a long sequence of still photographs taken at a resolution of 4256 x 2832 pixels at a rate of one every second. The high resolution allowed the ESA production team to create a 3840 x 2160 pixel movie, also known as Ultra HD or 4K. Playing these sequences at 25 frames per second, the film runs 25 times faster than it looks for the astronauts in space. The artistic effects of the light trails from stars and cities at night are created by superimposing the individual images and fading them out slowly. Alexander Gerst is a member of the International Space Station Expedition 40 crew. He is spending five and a half months living and working on the ISS for his Blue Dot mission.

Australia has a combined land and sea territory of more than 8 million square kilometers. Yet most of this is currently out of the reach of affordable communication. Now the University of South Australia's Institute for Telecommunications Research has turned this on its head, with the development of the Global Sensor Network. The Global Sensor Network is an innovative signal processing system which provides low cost, two-way, simultaeneous satellite communications to multiple users.

What do we see when we look at the Earth, and what do these observations mean for the years ahead? Barbara Ryan, secretariat director of the Intergovernmental Group on Earth Observations (GEO), discusses this Geneva-based, voluntary partnership of governments and organizations dedicated to coordinated, comprehensive, and sustained Earth observations and information — sharing what scientific observers worldwide are learning about the state and health of planet Earth.
