New Studies Increase Confidence in NASA's Measure of Earth's Temperature

Mars Imaged by Hubble

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

New insights about carbon and ice could clarify inner workings of Earth, other planets

Most people behave differently when under extreme pressure. Carbon and ice are no different.

Orbital View Of Nova Scotia, New Brunswick and the Bay of Fundy

Portions of the Canadian provinces of Nova Scotia and New Brunswick separated by the Bay of Fundy are pictured as the International Space Station orbited 257 miles above the North American continent.

Earth from Space: The Po Valley, Italy

This Copernicus Sentinel-2 image features the Po Valley, the most densely populated area in Italy, accounting for nearly half of the national population.

GRACE: What We've Learned from Water in Motion

When you hear news about ice loss from Greenland or Antarctica, an aquifer in California that is getting depleted, or a new explanation for a wobble in Earth's rotation, you might not realize that all these findings may rely on data from one single mission: the U.S.-German Gravity Recovery and Climate Experiment (GRACE).

Tropical Cyclone Ann Threatens Queensland

NASA-NOAA's Suomi NPP satellite passed over the Southern Pacific Ocean and captured a visible image of Tropical Cyclone Ann in the Coral Sea, off the east coast of Queensland, Australia.

Earth from Space: Milan, Italy

ESA's Living Planet Symposium - the largest Earth observation conference in the world - is being held on 13-17 May in Milan, Italy.

Tracking A Giant Ocean Vortex From Space

Researchers have found a new way to use satellites to monitor the Great Whirl, a massive whirlpool the size of Colorado that forms each year off the coast of East Africa, they report in a new study.

The Eastern Coast of the United States Seen From Orbit

This view of the eastern coast of the United States looks from (bottom left to right center) Virginia Beach, Virginia, all the way to Miami, Florida.

GRACE Data Contributes To Our Understanding Of Climate Change

The University of Texas at Austin team that led a twin satellite system launched in 2002 to take detailed measurements of the Earth, called the Gravity Recovery and Climate Experiment (GRACE), reports in the most recent issue of the journal Nature Climate Change on the contributions that their nearly two decades of data have made to our understanding of global climate patterns.

Earth from Space: Queensland Floods, Australia

The Copernicus Sentinel-2 mission takes us over Australia's northeast state of Queensland, where a large amount of sediment is visible gushing into the Coral Sea, close to the Great Barrier Reef lagoon.

Antarctica's Effect on Sea Level Rise in Coming Centuries

There are two primary causes of global mean sea level rise -- added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica's ice sheet is currently responsible for 20-25% of global sea level rise.

The Eye of the Sahara Viewed From Orbit

From an altitude of 255 miles, an Expedition 59 crewmember photographed the Richat Structure, or the "Eye of the Sahara," in northwestern Mauritania.

NASA Technology Pinpoints Potent Greenhouse Gases

Whether they're idyllic floating cotton balls on an otherwise blue sky or ominous grey swirls that block the sun, clouds all begin as an invisible dot of water vapor.

Earth from Space: Easter Island

The Copernicus Sentinel-2 mission takes us over one of the most remote islands in the world: Easter Island.

What Earth's Gravity Reveals About Climate Change

On March 17, 2002, the German-US satellite duo GRACE (Gravity Recovery and Climate Experiment) were launched to map the global gravitational field with unprecedented precision.

Earth from Space: Maritime Traffic in the English Channel

The Copernicus Sentinel-1 mission takes us over the busy maritime traffic passing through the English Channel.

Astro-ecology: Counting Orangutans Using Star-spotting Technology

A ground-breaking scientific collaboration is harnessing technology used to study the luminosity of stars, to carry out detailed monitoring of orangutan populations in Borneo.
