NASA to blastoff solar satellite to gather images of the sun

Despite Earthlings depending on the sun for survival, there's a lot that scientists still don't know about our solar system's star. NASA is looking to change this.

The U.S. space agency is launching a solar satellite called the Interface Region Imaging Spectrograph (IRIS) on June 26 to get a closer look at the sun's lower atmosphere. This part of the atmosphere is important because it is where most of the sun's ultraviolet emissions are generated, which are known to impact Earth's climate and the near-Earth space environment, according to NASA.

"IRIS data … Read more

Google said to deploy Wi-Fi blimps in Africa and Asia

How can the Internet be brought to areas that have no infrastructure for high-speed wireless? Beam the Wi-Fi networks down from flying objects, of course.

Google is reportedly working on creating wireless networks for more remote parts of the world, such as countries in sub-Saharan Africa and Southeast Asia, with sky-bound balloons and blimps, according to Wired.

Dubbed "high-altitude platforms," these mechanisms will reportedly be able to connect roughly a billion more people to the Internet worldwide, according to Wired. The blimps signals are said to be able to reach people in areas that are hundreds of square … Read more

Spot expands lineup with satellite-powered Global Phone

Satellite phones may seem like a niche technology, and in many ways they are. You won't need one while roaming city streets, but they can be invaluable if you're ever trekking far from civilization -- though that didn't stop this guy from using the HTC One on Mt. Everest.

If you're an in-the-wilds type, then Spot has a new option for you. On Monday, the company announced the Spot Global Phone, a satellite handset that promises a voice and data connection in hard-to-reach places.

Though most satellite phones tend to be bulky, the Spot Global weighs … Read more

Landsat watches over the Earth, documenting 28 years of change

NASA's Landsat 5, which recently set a Guinness World Record for the "Longest Operating Earth Observation Satellite," has been delivering high-quality, global data of Earth's land surface for 28 years and 10 months.

Using the annual Landsat satellite imagery captured since 1984, Google has created dramatic composites, alongside other Google Earth satellite imagery, depicting our changing world, the death and growth of natural lands, and humans' impact on the landscape.

The animated GIFs shown here chronicle the development and destruction of life on Earth, pulsing like a living being, with forests receding, water evaporating, and cities … Read more

Time-lapse images let you witness 28 years of Earth's changes

A newly released series of dramatic time-lapse satellite images, available at Google's Timelapse Web site, shows just how quickly the world's landscapes have changed in the last 28 years.

The pictures, captured by the series of Landsat satellites and released in conjunction with the U.S. Geological Survey, NASA, and Time magazine, show several startling examples of how humans and natural processes have changed Earth from 1984 to 2012. You'll see the depressing decline of the Columbia Glacier in Alaska, the blossoming of Dubai's epic cityscape, and Las Vegas' urban explosion. There's also an alarming look at the deforestation occurring in the Brazilian Amazon forest. … Read more

NASA's Fermi telescope dodges a 3,100-pound bullet

The near miss that happened with a high-tech telescope orbiting the Earth last month was so dramatic that I have to assume Hollywood thrill makers will soon be calling up NASA project scientist Julie McEnery to get all the details and begin determining how feasible it is to jam Ben Affleck or Morgan Freeman into the story line.

McEnery works with NASA's Fermi Gamma-ray Space Telescope, which has the mission of mapping the highest-energy light in the universe. On March 29, McEnery learned that Fermi and a dead Russian spy satellite, Cosmos 1805, were speeding toward the same point in space on nearly perpendicular orbits. They would miss being in that same place at the same time by only 30 milliseconds, likely passing within about 700 feet of each other.… Read more

Check the weather in style with the Yahoo Weather app

Yahoo Weather is a weather app that displays stunning Flickr photos as a backdrop to a wide range of weather information on your iPhone -- more than you get with Apple's weather app. There are certainly other options with more weather information, but for a quick look at what's happening in your area, Yahoo Weather is a good-looking and well-made app.

When you launch Yahoo Weather, you'll be asked immediately if the app can use your location so it can give you information on the weather around your area. From there you'll be presented with a … Read more

Satellite Eyes for Mac 1.2.4 Review

Some users find that their computer background images are important. Satellite Eyes for Mac, which automatically changes the background image to a map of the user's current location, is an interesting personalization option for Mac.

Available as a freeware program, Satellite Eyes requires no payments to unlock its full functioning. The program downloaded and installed easily, with no interaction required by the user. Upon startup, the program prompts the user to enable the computer's location settings. It would have been a nice feature if the program took the user to that menu automatically, but it did not. Once … Read more

Blast your angry face into space to ward off alien invasions

While NASA has been busy sending friendly messages out into space, it's overlooked one important issue. What if the aliens aren't friendly? Haven't the folks at NASA watched the "Alien" movies? A Kickstarter project is aiming to counteract NASA's open-arms policy by blasting a satellite into space with a less likeable version of humanity onboard.

In the 1970s, NASA sent two Pioneer spacecraft out into the universe bearing plaques with directions to Earth and illustrations of naked humans to show what extraterrestrial visitors could expect upon arrival at our humble planet. Ridiculo.us, creators of the Your Face in Space Kickstarter, is more concerned about warding off hostile invasion forces from beyond our solar system.… Read more
