ECOSTRESS Maps LA's Hot Spots

NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) captured new imagery of variations in surface-temperature patterns in Los Angeles County.

A study on past reversals of Earth's magnetic field has found that a rapid shift occurred within two centuries -- such an event in future would increase our exposure to the Sun's radiation that may cause trillions of dollars in power and communications systems damage.

The Earth's building blocks seem to be built from 'pretty normal' ingredients, according to researchers working with the world's most powerful telescopes.

In this paper I revisit proposed definitions of the boundary between the Earth's atmosphere and outer space, considering orbital and suborbital trajectories used by space vehicles.

A large multidisciplinary team of scientists, equipped with advanced underwater robotics and an array of analytical instrumentation, will set sail for the northeastern Pacific Ocean this August.

Long-Term Warming Trend Continued in 2017

Earth's global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.

A recent study by NASA and several partners has estimated, for the first time, the global impact of atmospheric rivers on floods and droughts, as well as the number of people affected by these atmospheric phenomena.

Humans have so profoundly altered the Earth that, some scientists argue, our current geologic epoch requires a new name: the Anthropocene.

OSIRIS-REx Views Earth During Flyby

This image was taken just hours after the spacecraft completed its Earth Gravity Assist at a range of approximately 106,000 miles (170,000 kilometers).

Plate tectonics has shaped the Earth's surface for billions of years: Continents and oceanic crust have pushed and pulled on each other, continually rearranging the planet's fa├žade.

Scientists have long held the belief that planets - including Earth - were built from rocky asteroids, but new research challenges that view.

It only takes a simple compass to demonstrate that the earth has a magnetic field - but it is quite difficult to explain how exactly it is created.

Summer Solstice Viewed From Orbit

On 21 June at 06:24 the 2017 summer solstice, as seen in this image from EUMETSAT's Meteosat-10 geostationary satellite, began.

A new image from NASA's Cassini spacecraft shows planet Earth as a point of light between the icy rings of Saturn.

Earth and Its Moon as Seen From Mars

From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon.

Astronauts on the International Space Station take pictures of Earth out their windows nearly every day; over a year that adds up to thousands of photos.

Thermostat in Earth's Upper Atmosphere

A team led by the University of Colorado Boulder has found the mechanism behind the sudden onset of a "natural thermostat" in Earth's upper atmosphere that dramatically cools the air after it has been heated by violent solar activity.

A new multi-institutional study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the Earth system, with Earth's ocean absorbing the extra heat.

Orbital Evening View Of The Home Planet

Multi-hued clouds are seen from approximately 250 miles overhead on the International Space Station.

Measuring Earth Moon Distances By Laser

The Earth-Moon-Sun system has traditionally provided the best laboratory for testing the strong equivalence principle.
