Floating Above An Ocean Planet

🔵 Thomas Pesquet: I was invited to the Ocean Pavilion at the IUCN World Conservation Congress this week, I had to get a rain check for professional reasons 😉.

The findings of a new study by the University of Liverpool provides further evidence of an approximately 200-million-year long cycle in the strength of the Earth's magnetic field.

The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion.

New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth's outer core, and the work suggests the core could be the planet's largest reservoir of that element.

Green Seaweed In The Yellow Sea

Algae made headlines around the world in June 2008 when an enormous bloom choked the coastal waters off Qingdao, China, the site of sailing events for that year's Olympic Games.

The Yukon-Kuskokswim Delta is one of the world's largest deltas, and it stands as a remarkable example of how water and ice can shape the land.

The global cryosphere--all of the areas with frozen water on Earth--shrank by about 87,000 square kilometers (about 33,000 square miles), a area about the size of Lake Superior, per year on average, between 1979 and 2016 as a result of climate change, according to a new study.

Clouds And Colors Seen From Orbit

Thomas Pesquet: These two pictures show random clouds, and they are nothing particularly exceptional for a view up here, but they have nice colours.

This composite photograph, a combination of several distinct photographs, of Cuba, the Bahamas and southern Florida was captured as the International Space Station orbited 263 miles above the Caribbean Sea.

NASA will design a new set of Earth-focused missions to provide key information to guide efforts related to climate change, disaster mitigation, fighting forest fires, and improving real-time agricultural processes.

Deforestation dropped by 18 percent in two years in African countries where organizations subscribed to receive warnings from a new service using satellites to detect decreases in forest cover in the tropics.

Sentinel-6 Michael Freilich, a joint U.S.-European satellite built to measure global sea surface height, has sent back its first measurements of sea level. The data provide information on sea surface height, wave height, and wind speed off the southern tip of Africa.

A new study from scientists at Scripps Institution of Oceanography at UC San Diego and the University of Chicago sheds light on a hotly contested debate in Earth sciences: when did plate subduction begin?

Long ago, all the continents were crammed together into one large land mass called Pangea.

Cataloging Craters On Earth

Prof. Dr. Thomas Kenkmann, geologist from the University of Freiburg's Institute of Earth and Environmental Sciences, together with mineralogist Prof. Dr. Wolf Uwe Reimold from the University of Brasilia, Brazil, and Dr. Manfred Gottwald from the German Aerospace Center (DLR) published an atlas providing a comprehensive overview of all known impact craters on every continent.

Chasing Satellites With Jacques Cousteau

Leaving from Nassau on a Tuesday night in late August 1975, Jacques Cousteau, his divers, and a team of scientists set out on the Calypso for a three-week expedition to determine if the young Landsat satellite mission could measure the depth of shallow ocean waters.

Scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests

Mediterranean Sea At Night From Orbit

This nighttime view from the International Space Station looks across the Mediterranean Sea ringed by the coastal city lights of southeastern Europe, the Middle East and north Africa.
