Here’s a fantastic view of our home planet taken by the Russian weather satellite Electro-L. And while Elektro-L can take gigantic photographs of the entire planet every 30 minutes, it only can get a fully-lit view like this just twice a year — at the spring and autumn equinoxes. This image was taken during the autumnal equinox on September 22, 2013.
Below is an animated gif of the view, going from day to night.

Elektro-L orbits Earth in a geostationary orbit 36,000 kilometers above the equator, and with the Sun exactly behind the satellite on the equinox — the day the north and south poles get the same amount of light — the entire disk is fully lit.
You can see the typhoon Usagi raging over Southeast Asia, clouds and rain over Russia and swirling clouds in the ocean near Antarctica.
Electro-L was launched in 2011 and is Russia’s first geostationary weather satellite. It’s a data hog – sending back 2.56 to 16.36 megabits per second, with resolution of 1 kilometer per pixel. You can see the big 5000 x 5000 pixel version at the Electro-L website.
Thanks to Vitaliy Egorov for sharing this image with UT. He has posted the images at his zelenyikot/livejournal website.

Enjoy this tour of the Arctic and Greenland, courtesy of the pilots of IceBridge, a six-year NASA mission to survey the ice at both of Earth’s poles. These views come from NASA’s P-3B aircraft, and the video is a selection of some of the best footage from the forward and nadir cameras mounted to the aircraft taken during IceBridge’s spring deployment over Greenland and the Arctic Ocean.
This airborne mission is collecting radar, laser altimetry, and other data on the changing ice sheets, glaciers, and sea ice of the Arctic and Antarctic. It is the largest airborne survey of Earth’s polar ice ever flown, and it will provide an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. These flights will provide a yearly, multi-instrument look at the behavior of the rapidly changing features of the Greenland and Antarctic ice.
Data collected during IceBridge will help scientists bridge the gap in polar observations between NASA’s Ice, Cloud and Land Elevation Satellite (ICESat) — in orbit since 2003 — and ICESat-2, planned for late 2015. ICESat stopped collecting science data in 2009, making IceBridge critical for ensuring a continuous series of observations.

Astronauts have tried to explain the view of Earth from space, with many saying that there just aren’t the words to describe how beautiful it is. In the latest episode of the “Science Garage,” recent ISS astronauts Tom Marshburn and Chris Hadfield might do the best job so far of relating not only the “incredible and unwrapping perspective of looking at the Earth,” but how it changed their perspective of humanity. Hadfield compares coming into the cupola of the International Space Station as being like “entering the Sistine Chapel.”

Recently, Italian astronaut Luca Parmitano spent a “night flight” in the Cupola of the International Space Station in hopes of capturing night-time images of his home country from space. But he saw so much more, including this incredible image of the crescent Moon rising among bright blue noctilucent clouds. These wispy and mysterious clouds appear in Earth’s mesosphere — a region extending from 30 to 53 miles (48-85 km) high in the atmosphere — at twilight, usually in early summer. They can be seen from Earth’s northern hemisphere and, obviously, are visible from space too.
You can read about Parmitano’s night flight and see more of the images he took at his Volare blog. At the close of his image-taking night flight he says, “It’s late, and tomorrow will be a long day. With those lights still filling my eyes, I slowly close the seven windows and cross the Station to return to my sleeping pod. Not even dreams could replace the beautiful reality that revolves, oblivious, beneath us.”

I love those images taken from the International Space Station that show the Moon rising or setting above Earth’s limb, and when I first saw this image posted on Universe Today’s Flickr Group page, I thought someone had randomly posted one of those images taken by an astronaut on the ISS. But then I saw it was taken by Patrick Cullis, one of our “regulars” in our featured astrophotography posts.
This very beautiful, crisp and clear image was taken from a meteorological balloon at 86,000 feet (26,200 meters) above Earth, and it was no fluke that Patrick captured the Moon setting above Earth — it was planned.
“Once I knew the weather was going to work out for a launch I really planned out what time it needed to happen for the Moon to show up in the frame,” Patrick said via Flickr. “Definitely got lucky since the camera is just swinging around randomly under the balloon.”
He calls this image “Divided Moon,” as it shows the Continental Divide in Colorado. “I-70 can be seen snaking up from the bottom center towards Georgetown (valley stretching from left to right,) Loveland Pass, and the Eisenhower Tunnel,” Patrick explained. If you click on the image above (or go here to see it on Flickr) you can see other landmarks labeled.

Herbal Earth: that’s the title of a spectacular collection of vivid new views of the Earth’s vegetation captured over the past year by the Suomi NPP satellite.
NPP is short for National Polar-orbiting Partnership – an Earth science satellite partnership between NASA and the National Oceanic and Atmospheric Administration (NOAA).
Although it’s rather reminiscent of the manmade ‘World at Night’ – its actually the ‘Natural World of Living Green Life.’
The Suomi NPP satellite data were collected with the Visible-Infrared Imager/Radiometer Suite (VIIRS) instrument from April 2012 to April 2013 and used to generate this gallery of images and animations – released by NASA and NOAA on June 19.
Western Hemisphere -Vegetation on Our Planet. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas.

Suomi NPP was launched on October 28, 2011 by a Delta II rocket and placed into a sun-synchronous orbit 824 km (512 miles) above the Earth. It orbits Earth about 14 times daily.
The VIIRS instrument measures vegetation changes over time by looking at changes in the visible and near-infrared light reflected by vegetation. The 22-band radiometer sensor can detect subtle differences in greenness.

The data are incorporated into the Normalized Difference Vegetation Index (NDVI) which represents the photosynthetic potential of vegetation.
The NVDI measures and monitors plant growth, vegetation cover and biomass production from the Suomi NPP satellite information.

This is an article from our archive, but we’ve updated it with this spiffy video.
Every now and then I go looking for a free aerial view of my home. It’s amazing what’s available through the internet now, totally free. Thanks to commercial Earth observation satellites, and internet tools that make these photos accessible through the internet, it’s easy to see your house from space.
In our modern space age, there are more than 8,000 satellites currently orbiting the Earth. The vast majority of these are relaying data to and from the Earth, and many are equipped with high power cameras. Just look up into the sky any night, and you’re sure to see satellite after satellite passing overhead. But what are some ways you can get access to these satellite and aerial images of your house?
Satellite Images of the Whole Earth
If you want to go way out and just see a satellite image of the entire planet, there are some solutions for you: weather satellites. For example, NOAA’s Geostationary Operational Environmental Satellites (GOES) release images of an entire hemisphere of planet Earth every 3 hours. From these images you can see major weather patterns affecting parts of the Earth. But you really can’t see any specific spot on Earth with any detail.
What is really cool about these satellite views is that they’re live. The weather systems you’re seeing in those images are happening on the planet right now.
If you don’t want a live view, and really just want to see a beautiful view of the Earth’s hemisphere, check out these images produced by NASA. Here’s a composite photograph that shows the Earth’s Western Hemisphere, and here’s a view of the Earth’s Eastern Hemisphere.
Zoom in. Let’s see Satellite Pictures of Houses
If those whole Earth pictures don’t give you enough detail, let’s zoom in, and see some pictures of houses from space. The best tool on the market, in my opinion, is the service from Google Maps. All you need is a web browser and a connection to the internet. When you first start up, Google Maps displays a satellite view of North America. You can then zoom in, or pan the camera around to see any location on Earth. You can also type in the address of the location that you want to see. Once you do that, you’ll get a free satellite view of your house. You can save the image or print it off.
Another cool tool from Google is Google Earth. You can access by going to http://earth.google.com. The main difference between Google Maps and Google Earth is that you have to download and install Earth on your local computer (they have a version for PCs, Mac, Linux, and even the iPhone). Once you’ve downloaded and installed Google Earth, you can see a 3-dimensional view of Earth that you can zoom in and out and spin around. You can type in your address and get a view of your house from above. I actually like the printing function of Google Earth better, since it’s using your printer directly, and not going through the web browser.
And if you really hate using products from Google, no problem. There are similar services from Yahoo and Microsoft. Microsoft’s mapping service used to be called MSN Maps, and now it’s been changed to Bing Maps with their new identity. The Yahoo service is called Yahoo Maps, and it’s very similar to Google Maps. The two services do have some big differences, though, and there’s a cool application that lets you see the two of them side-by-side. I used it for my home and found that Google Maps has better resolution maps for my city.
Where Do All these Pictures Come From?
Google Maps and the other internet mapping services are really just customers for the satellite services that actually take these photographs from space. There are a few major services on the market, including GeoEye. GeoEye’s main competitors include DigitalGlobe and Spot Image.
Each company has a fleet of Earth observation satellites, with a capability of resolving features on the surface of the Earth as small as about 45 cm (18 inches). In other words, an object 45 centimeters across would appear as a single pixel in their photographs.
Each of these services allow customers to purchase satellite imagery directly, but I’ll warn you, the prices are extremely high: hundreds or even thousands of dollars for satellite imagery. You typically can’t buy directly from the satellite company itself, but through their international partners.It’s better to stick to the free sources.
Are These Live Satellite Views?
When you look at these amazing views of your house from space, you might wonder if this is live. If you walk outside and look up, will you be able to see yourself from space? Unfortunately, no. All of the free satellite images you’re accessing were captured by various spacecraft over the last couple of years.
You can actually get a pretty good sense of when the picture was taken by the image of your property. For example, in the photo of my house from space, I can see a car that I sold a couple of years ago. Obviously, this image isn’t live, it’s at least a couple of years old – even a decade old in some cases. A live satellite view of your house, is still a few years off.
There are some services which will give you a live view of Earth from space. For example, you can access a live broadcast from NASA’s International Space Station. About 40% of the time, if you follow this link you can see a live view of Earth from the space station. Another service called Urthecast will be attaching a high definition camera to the International Space Station in 2013 to broadcast a live view of Earth from space.
This picture, apparently the first verifiable photo of the Great Wall of China shot from low Earth orbit, was taken by International Space Station Commander Leroy Chiao on Nov. 24, 2004. Credit: NASA
One popular myth about space exploration is that the Great Wall of China is the only human-built structure that can be seen from space. But this is not true. The reality is that you can’t easily see the Great Wall with the unaided eye, even from low Earth orbit. And certainly, the Apollo astronauts couldn’t see it from the Moon, even though that urban legend has been widely circulated.
Canadian astronaut Chris Hadfield, who spent five months aboard the International Space Station in 2012-2013, reiterated the facts about the Great Wall’s visibility from space.
“The Great Wall of China is not visible from orbit with the naked eye,” Hadfield said via Twitter. “It’s too narrow, and it follows the natural contours and colours [of the landscape].”
Additionally, when China’s first astronaut, Yang Liwei, went into space in 2003, he said that he couldn’t see the structure of the Great Wall from out his capsule window.
NASA has confirmed that US astronaut Leroy Chiao took what is thought to be the first verifiable image of the Great Wall of China from out his window on the International Space Station in 2004, using a zoom lens. He photographed a region of Inner Mongolia, about 200 miles north of Beijing, but said Chiao himself said he didn’t see the wall with his unaided eyes, and wasn’t sure if the picture showed it.
The image above was taken with a 180mm zoom lens. If you can’t make out the Great Wall in the image above, here’s a cropped version of the image with annotation to help make out the feature:
This photo of central Inner Mongolia, about 200 miles north of Beijing, was taken on Nov. 24, 2004, from the International Space Station. The yellow arrow points to an estimated location of 42.5N 117.4E where the wall is visible. The red arrows point to other visible sections of the wall. Credit: NASA.
What human-made structures are visible from space? Space Station astronauts have said the ancient pyramids at Giza are relatively easy to see out the window, but most visible are roads or long bridges across straits. Those features stand out as straight lines on the landscape, such as this image shared by Chris Hadfield:
‘One straight human line drawn onto incredibly rough terrain,’ said astronaut Chris Hadfield about this image. Credit: NASA/CSA/Chris Hadfield.
And, of course, at night cities are visible from space because the light they produce. You can see some stunning images here that NASA released in 2012 from the Suomi NPP satellite of city lights from space.
The Apollo astronauts confirmed that you can’t see the Great Wall of China from the Moon. In fact, all you can see from the Moon is the white and blue marble of our home planet.
With all of the human construction, many buildings and other structures can be seen from space. But you can’t see the Great Wall of China from space.

The track of the tornado that struck Moore, Oklahoma on May 20, 2013 is visible from space in this false color image taken on June 2, 2013 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite.
The tornado that devastated the region around Moore and Newcastle, Oklahoma on May 20, 2013 has been determined to be an EF-5 tornado, the most severe on the enhanced Fujita scale, and has been called one of the most powerful and destructive tornadoes ever recorded. In this new image taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, the scar of destruction on the Oklahoma landscape is clearly visible from space. In this false-color infrared image, red highlights vegetation, and the tornado track appears as a beige strip running west to east across this image; the color reveals the lack of vegetation in the wake of the storm.
According to the National Weather Service, the tornado was on the ground for 39 minutes, ripping across 17 miles (27 kilometers) from 4.4 miles west of Newcastle to 4.8 miles east of Moore. At its peak, the funnel cloud was 1.3 miles (2.1 kilometers) wide and wind speeds reached 210 miles (340 km) per hour. The storm killed at least 24 people, injured 377, and affected nearly 33,000 in some way.
In this image, infrared, red, and green wavelengths of light have been combined to better distinguish between water, vegetation, bare ground, and human developments. Water is blue. Buildings and paved surfaces are blue-gray.
You can also see an interactive satellite map from Google and Digital Globe, showing detail of every building that was damaged or destroyed. Satellite data like this are helping to assist in the recovery and rebuilding of the area. Satellite imagery can provide a systematic approach to aiding, monitoring and evaluating the process.

This is just a gorgeous shot of our home planet from the International Space Station, shared by astronaut Karen Nyberg via Twitter. While many pictures of Earth from space show a bright view of our planet, this view of the world plunging into darkness provides a unique, not-often-seen view. If a picture can be this beautiful, imagine what must look like in person.
Nyberg is sharing her experiences via Twitter and also — I believe she is the first astronaut sharing on Pinterest. She describes herself as “Aspiring quilter, crafter, artist” (perfect for the Pinterest crowd) in addition to being an astronaut by day, and said she hopes to do some crafting in space if she has any spare time. Nyberg has a special board for “Hair in Space” (which includes both bald pates and gravity defying hair,) hoping to inspire the younger generation of women to get interested in space exploration. “When girls see pictures of ponytails, don’t you think it stirs something inside them that says, that could be ME up there!” Nyberg writes.
