Viewing A "Glory" From Orbit

Despite humankind's scientific prowess there are still many phenomena that defy explanation or a common agreement on why something happens.

Five new NASA Earth science campaigns will take to the field starting in 2020 to investigate a range of pressing research questions, from what drives intense East Coast snowfall events to the impact of small-scale ocean currents on global climate.

How many times have you stepped outside into a surprise rainstorm without an umbrella and wished that weather forecasts were more accurate?

A new NASA-led study helps answer decades-old questions about the role of smoke and human-caused air pollution on clouds and rainfall.

A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect -- in both shape and in rotation.

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.
