The positions of the planets next month will mean diminished communications between Earth and NASA's spacecraft at Mars.

With data from 73 ice and sediment core monitoring sites around the world, scientists have reconstructed Earth's temperature history back to the end of the last Ice Age.

Looking out at Earth's surface from the International Space Station (ISS), astronauts and cosmonauts frequently observe sunglint highlighting both ocean and inland water surfaces.

NASA's Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of space.

The striking coincidences of the asteroid 2012 DA14 flying close to the Earth, and a large meteor crash in Russia's Chelyabinsk region on 15 February, showed again the need for coordinated international efforts to predict, and if necessary, mitigate such threats posed by near-Earth objects in the future.

Close Earth Flyby By Asteroid 2012 DA14

A little-known asteroid will skim past Earth on 15 February, passing just 28 000 km from our planet. The 50 m-diameter chunk of space rock was discovered in last year by ESA-sponsored amateur astronomers in Spain.

A nearby short-duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhauser.

NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1988, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

Air Quality Suffering in China

Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history.

As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation - which would bombard astronauts on deep space missions to places like Mars - could accelerate the onset of Alzheimer's disease.

Mission Accomplished for Landsat 5

Today the U.S. Geological Survey announced that Landsat 5 will be decommissioned over the coming months, bringing to a close the longest-operating Earth observing satellite mission in history.

New Views of Earth at Night

Scientists unveiled today an unprecedented new look at our planet at night. A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before.

On Oct. 28, 2011, the Suomi National Polar-orbiting Partnership (NPP) satellite successfully blasted into orbit in a spectacular night launch from Vandenberg Air Force Base, Calif.

New Theory on Earth and Moon Formation

New research, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five times the size of Mars.

Most researchers imagine the initial oxygenation of the ocean and atmosphere to have been something like a staircase, but with steps only going up.

This Envisat image shows us a very rare, cloud-free view of Iceland. Located in the North Atlantic Ocean east of Greenland and immediately south of the Arctic Circle, Iceland is the westernmost European nation, and has more land covered by glaciers than the whole of continental Europe.

Stunning Video Of Earth at Night

From high above the Earth, the International Space Station (ISS) provides a unique vantage point to view our home planet. Stunning time-lapse photography of cities, aurora, lightning and other sights are seen from orbit.

Today, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument on MSG-3 captured its first image of the Earth. This demonstrates that Europe's latest geostationary weather satellite, launched on 5 July, is performing well and is on its way to taking over operational service after six months of commissioning.

Why Is Earth So Dry?

With large swaths of oceans, rivers that snake for hundreds of miles, and behemoth glaciers near the north and south poles, Earth doesn't seem to have a water shortage. And yet, less than one percent of our planet's mass is locked up in water, and even that may have been delivered by comets and asteroids after Earth's initial formation.

Suomi NPP Begins Direct Broadcast

Real-time data that will be used in everything from weather forecasts to disaster response is now being beamed down to Earth from a cone-shaped appendage aboard the nation's newest Earth-observing satellite.
