Google Maps is now letting users explore Earth's far-reaching lands filled with flickering lights using imagery from NASA and the National Oceanic and Atmospheric Administration's "Black Marble."

The Web giant announced the launch of its own Earth at Night today, which is a global view and animation of the images taken from NASA and NOAA's jointly operated Suomi NPP satellite. These series of images show what the Earth looks like from space once the sun sets.

"It took 312 orbits to get a clear shot of every parcel of Earth's land surface and … Read more

When the skies darken and the lights flicker on, the areas of Earth we populate gain a surreal glow that traces our existence in a breathtaking way.

A new series of photos released by NASA and the National Oceanic and Atmospheric Administration's jointly-operated Suomi NPP satellite gives us a clearer view than ever before at our illuminated world during nighttime. Perhaps you could compare the view to a series of electrified blood vessels and arteries. … Read more

Live in an area prone to flash floods, hurricanes, blizzards? Smartphone users will soon get a severe-weather alert from the National Weather Service, a division of the National Oceanic and Atmospheric Administration.

The new nationwide emergency alert system, called the Wireless Emergency Alerts (WEA), sends 90-character text messages to smartphones of people facing extreme weather conditions. Severe weather defined by the NOAA includes tornadoes, flash floods, hurricanes, extreme wind, blizzards and ice storms, tsunamis, and dust storms. Note that thunderstorms aren't on the list because they occur so frequently. … Read more

Whether you live in rainy Seattle or are expecting thunderstorms in Albany, N.Y., it's always a good idea to carry solid weather apps on your iPhone for quick forecasts.

The Weather Channel released version 5.0 of its app late last week with an upgraded interface and a few more features that will be useful to amateur meteorologists everywhere, but it doesn't have everything. One of the more useful parts of any local weather forecast is when you get to see the live Doppler radar for your location. The Weather Channel will show you a radar overlay, but you can't see it move. That's where the second app in this one-two punch comes in, NOAA Hi-Def Radar.

With this pair of apps, you might find that one or the other is the best weather app for you, but hopefully this comparison will help you find what best fits your needs.… Read more

You might not think that an iPad could help save whales, but that's just what an app released today is designed to do.

Known as Whale Alert, the iPad app is designed to help ship captains avoid colliding with whales in congested shipping channels.

Specifically, the app, which was created in partnership between the International Fund for Animal Welfare (IFAW), private companies, academia, and the government, is meant to link "the bridge of a ship to the latest data about right whale detections and informs users when their vessels enter right whale management areas."

North Atlantic right … Read more

The burning of fossil fuels and the release of carbon dioxide into the atmosphere don't affect just the air--it also impacts the Earth's oceans, according to U.S. National Oceanic and Atmospheric Administration (NOAA).

Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.

Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more

People who wouldn't normally see auroras are being treated to stunning sights today thanks to the largest solar radiation storm since 2005.

The storm is creating colorful auroras throughout the North and South Poles that stretched to countries that don't normally see the lights, such as England. The National Oceanic and Atmospheric Administration has maps on its Web site of the likelihood of seeing a nearby aurora.

This video by Helge Mortensen shows the aurora borealis at Tromvik Norway:

This video by NASA's Solar Dynamics Observatory shows a long duration flare erupting on the Sun and sending … Read more

Across the United States, people are experiencing some of the hottest weather of the year. Many cities are topping out in the hundreds, and some are even getting close to 110. Even a quick glance at the current weather map tells the story: It is hot just about everywhere and if you don't have air conditioning or a body of water nearby, you're probably not feeling too happy about the sunny weather.

This week's collection of apps are all about checking the weather to see when you can get some relief. The first gives the most weather information on one screen so you can know everything at a glance. The second is a fairly simple weather app, but offers one very useful feature. The third is the most complex, with both viewable weather data and national radio updates for weather in your area. Hopefully, with these apps in hand, you'll be able to see some light at the end of a very hot tunnel.… Read more

With hundreds of thousands of gallons of oil threatening some of America's richest wetlands and fisheries, crews grappling with the massive spill in the Gulf of Mexico have at their disposal new technologies never before available in such a disaster.

To be sure, oil spill response is a largely low-tech business that hasn't changed that much over the years. But as the aftermath of the explosion and subsequent sinking of the semi-submersible offshore oil rig Deepwater Horizon looks increasingly like it may result in the country's worst environmental catastrophe in decades, there are some ways that technology … Read more
