If Our Eyes Could See Wireless Signals, Here's How Our World Might Look 

Our lives today depend largely on systems and infrastructure that is invisible — a hidden landscape of webs and waves that come from cell towers, routers, satellites and more.


Here's What California's Thick Blanket Of Wildfire Smoke Look Like From Orbit

NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS, records what’s happening on the surface of the Earth every day or two. That means recording dust storms, hurricanes, typhoons — and, as was the case this week, a thick layer of smoke over California.


Wildfires Have Devasted 5 Million Acres, And Alaska Is Still Burning

Alaska’s wildfires burned through their 5 millionth acre this week, making 2015 the third most destructive wildfire season ever recorded in the state, and NASA’s Terra satellite captured this striking image of the fires from above.


What's The Point Of A Fly-By When We Have The Tech To Go Into Orbit?

New Horizons’ fly-by of Pluto and its moons is the latest in a historic string of missions to objects in the solar system. But given that a fly-by lasts for just a short time, how much can we really get out of it? There’s no doubt that the mission will yield a great deal of interesting data, but surely more would be gained if the spacecraft could go into orbit for a number of days or actually land on the surface and take physical samples.


The Algerian Sahara Looks Stunning From Orbit

When you think “Sahara desert” your mind’s eye probably conjures images of tawny, windswept dunes stretching monotonously into the horizon. But satellites have a way of giving us a strikingly different, often much more interesting view of our world.


The Most Beautiful Landscapes From 10 Years Of Google Earth

Exactly 10 years ago, Google uploaded an announcement to its press page: Google Launches Free 3D Mapping and Search Product!

Google Earth turns 10 today, and to celebrate, the engineering team added 1500 new images to its great Earth View project, where it collects the most compelling images recorded by its source satellites.


A Space Lawyer Explains How We'll Forge A Civil Society Off Earth

Without even looking a century or so ahead when we’ll take a Virgin Galactic flight to spend our summers on Europa, there are many legal issues that are already confronting humanity in space. That’s why space lawyers are plenty busy today examining the particular economic and societal challenges found where Earth ends and space begins.


The San Francisco Bay Area From 640 Kilometres Above The Earth's Surface

This shot was taken by Landsat this spring and beyond being unbelievably beautiful, it’s also a great example of what Landsat does best: Give scientists a macro look at land cover, urban patterns, and geological features.


Amateur Satellite Trackers Found The Secret X-37B Space Plane In Orbit

The US Air Force’s supersecret X-37B was launched into orbit for the fourth time last week, and amateur satellite watchers have promptly identified its secret orbit — also for the fourth time. There is, you see, a small army of amateurs who keep track of over 300 spy satellites, often with little more than a pair of binoculars.


The Himalayas Dropped Almost A Metre After The Nepal Earthquake

The earthquake in Nepal was so violent it moved mountains. Satellite imagery shows that the parts of the Himalayas sank three feet (91cm) — and the area around it as much as five feet (152cm) — as tectonic plates snapped under extreme pressure. But the mountains will regain their height, slowly but surely, thanks to the geologic forces at work.
