Frame one of THEMIS/ASI images shows auroras on a collision course on Feb. 29, 2008. (Imag...

A network of cameras deployed around the Arctic to understand the trigger mechanism for the beautiful light display called the aurora borealis – also known as the Northern Lights – has discovered that sometimes the vast curtains of aurora borealis collide, producing a stunning outburst. The reason no one on Earth has ever noticed these collisions before is that they occur on such a vast scale it takes a network of sensitive cameras spread across thousands of miles to get the whole picture.  Read More

Power collected by solar panels in space is beamed back to earth in the form of radio freq...

Earlier this year we reported that California’s biggest power utility company, Pacific Gas and Electric (PG&E), was seeking to buy power generated by space-based solar panels pending regulatory approval from its home state of California. Now, true to the State’s goal of increasing its reliance on a diverse supply of renewable energy resources, the California Public Utilities Commission (CPUC) has granted regulatory approval, with energy start-up Solaren tackling the challenge of making the project work.  Read More

The ejecta plume about 20 seconds after the LCROSS impact (Images: NASA)

Scientists have long speculated about the source of significant quantities of hydrogen that have been observed at the moon's lunar poles, and just a few months ago NASA announced that water molecules were indeed present, but in relatively small amounts. Now the Lunar CRater Observing and Sensing Satellite (LCROSS) that was employed to shed some more light on the presence of water on the moon, looks like it has done just that with preliminary data indicating the mission successfully uncovered water in a permanently-shadowed crater.  Read More

The Soil Moisture and Ocean Salinity (SMOS) mission will make global observations of soil ...

The 658kg (1,450 lb) Soil Moisture and Ocean Salinity (SMOS) satellite launched by the European Space Agency (ESA) this week is the first ever satellite designed both to map sea surface salinity and to monitor soil moisture on a global scale. The unique radiometer it carries will enable passive surveying of the water cycle between oceans, the atmosphere and land thereby playing a key role in the monitoring of global climate change.  Read More

Global Positioning System (GPS) devices have permeated society to the point where millions of us rely on them daily for directions, locations and traffic avoidance (if only they could tell me where I left my car keys). GPS satellites send signals to a receiver in your handheld or car-based GPS navigator, which calculates your position on the planet based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver. But have you ever thought what tells the GPS satellites where they are in the first place?  Read More

Street View, regular and satellite View - Google Maps Navigation does them all

Every platform needs a killer app and for the Android OS the early contender for that title has to be the just announced Google Maps Navigation for mobile. Only available for Android 2.0 phones, the new application takes the current Google Maps for mobile and gives it a hefty shot of steroids. Most of the new features that set the app apart from most in-car turn-by-turn navigation systems come courtesy of its Internet connectivity, which makes it possible to access a wealth of relevant information residing on Google’s servers while out and about.  Read More

An image from the orbiting Hyperspectral Remote Sensor (HRS)

Combining sophisticated sensors in orbit with sensors on the ground and in the air has led researchers at Tel Aviv University (TAU) to create a “Hyperspectral Remote Sensor” (HRS) that can give advance warnings about water contamination after a forest fire, alert authorities of a pollution spill long before a red flag is raised on Earth, or inform the population where a monsoon will strike.  Read More

Just when you thought your room wasn’t big enough for a home theater, JVC has come to the rescue with its ultra-slim amplifier and speakers, designed to sit perfectly alongside or underneath your ultra-slim 50-inch TV or projector screen. The SP-FT model from JVC is a pair of 31mm thin satellite speakers and matching amplifier which pump out an adequate 80W total output over four independent channels and support Dolby Digital, DTS and AAC formats.  Read More

Competing with the big boys ... the Livestream Livepack lets you record and broadcast live...

A new backpack from Livestream called the Livepack puts a broadcast TV truck on your shoulders without the weight or cumbersome dimensions – but with the same broadcast capabilities. If you get A-list invitations that put you up close and personal with celebrities, or just fancy yourself as part of the paparazzi, this is a must-have device. The Livestream Livepack crams into a backpack the hardware unit to encode and transmit HD video, a Firewire cable, and six load-balanced built-in 3G modems in order to get the highest possible available bitrate. The system even comes with a dedicated IP address to stream to your Livestream channel - you’ll be a professional roving reporter before you know it (as long as you can provide your own Firewire DV camera).  Read More

Pretty as a picture … this mosaic of M31 merges 330 individual images taken by the ultravi...

In a galaxy far, far away … about 2.5 million light years, in fact, lie approximately 20,000 hot, young stars and dense clusters that comprise the Andromeda Galaxy. The galaxy, known as M31 in the constellation Andromeda, was recently captured by an ultraviolet optical telescope aboard NASA’s Swift satellite, and delivers the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.  Read More
