The Blue Marble: Views of Earth From Far Away

Original image

In January 2012, the newly launched weather satellite NPP Suomi had gathered enough swaths of data to cover the entire Earth. To commemorate this, the mission team assembled this into a map and projected it over the globe:

NPP's "Blue Marble," western hemisphere, data acquired from about 824km altitude

It's a synthetic view; NPP flies too close to ever see this much of Earth at once. But there are spacecraft that do get that vaunted view—and more besides. Let's look at the Earth from increasingly more distant viewpoints...

35,786 km

GOES-7 image of Hurricane Andrew making landfall in 1992, from Geosynchronous Orbit, 35,786 km altitude

45,000 km


The original "Blue Marble" photo, taken by Apollo 17 during transearth cruise, 45,000km altitude

55,831 km

Mercury-bound MESSENGER got this during an Earth gravity assist flyby, at a distance of 55,831 km

384,000 km

The most famous of the Earthrise photos: Earth rising over the lunar limb as viewed from Apollo 8, distance of about 384,000 km

384,000 km


The USAF's Clementine spacecraft looks back from the moon, about 384,000 km away

384,000 km

Lunar Reconnaissance Orbiter looks back at Earth from lunar orbit, about 384,000 km away

400,000 km


The NEAR spacecraft, en route to 433 Eros, took this during a flyby of Earth, at a distance of 400,000 km

2 - 2.7 million km


Taken by Galileo during its first Earth gravity-assist flyby, between 2 and 2.7 million km away

2.6 million km

Mariner 10 looks back during departure, at a distance of 2.6 million km; a composite of two images, one of Earth and one of the Moon, moved together to show relative scale

3.5 million km

2011 Mars Odyssey looked back at Earth from 3.5 million km, in a view that shows the true size and distance relationship between Earth and Moon

6.2 million km

Taken during Galileo's second Earth gravity-assist flyby, about 6.2 million km away; the Earth and Moon are truly in conjunction

11.66 million km


Voyager 1 took this at a distance of 11.66 million km, while departing Earth; it's the first view showing both Earth and Moon together in a single frame without compositing and without being in orbit around either

From Mars

The Mars Exploration Rover A, "Spirit," saw Earth in the predawn sky on Sol 63 of its mission; the first image of Earth from the surface of another planet

142 million km

Mars Reconnaissance Orbiter took this from Mars orbit, at a distance of 142 million km

183 million km

MESSENGER, looking back at Earth from Mercury, at a distance of 183 million km

183 million km

Also MESSENGER, this is a solar system portrait from Mercury; the Earth image is part of this

1.5 billion km


Cassini took this from Saturn orbit, at a distance at the time of 1.5 billion km. Look carefully through the rings; there's a bright star in there. It's Earth.

1.5 billion km

6 billion km

February 14, 1990, Voyager 1 set a record that still stands for the most distant image of Earth. It is over 6 billion km away. This montage is a solar system family portrait, showing six of the planets. Mercury was too close to the Sun to be visible at this range. They attempted to photograph Mars, but it was too faint for Voyager's camera.

6 billion km


Enhanced, enlarged view of Earth from the solar system portrait; Carl Sagan called this image the "Pale Blue Dot." It is the most distant view we've ever recorded of ourselves.

Can You Spot the Python Hiding in the Photo?

A homeowner in Cooroy, Queensland, Australia came home to find a rather frightening surprise in his garage: what appeared to be a large snake was actually a pair of breeding pythons. Fortunately, the eagle-eyed experts at Sunshine Coast Snake Catchers, a professional reptile relocation service, noticed that there was a second snake and snapped this photo after removing the first one. Would you have been able to spot the second slithery guy? Take a look at the photo above and see.

Give up? Scroll down to see where it was hiding.

Lazy Cyclists Help Make These Massive Bike Graveyards in China

When bike share programs go right, they can make life easier for commuters while reducing a city’s impact on the environment at the same time. When they don't go exactly as planned, they can create sprawling bicycle graveyards like the one seen in these photos.

The eerie scenes, recently spotlighted by WIRED, can be found throughout the city of Hangzhou, China. Like many large cities, Hangzhou is home to an official bike share program. But there are also private bike share companies that give cyclists the option to pick up a bike and leave it wherever they please rather than return it to an official docking station. The result is thousands of bikes scattered around the city like junk.

In response to complaints, the city of Hangzhou has begun collecting these abandoned bikes and storing them in lots. These aerial images are a good indication of the sheer number of bikers the city has—and they also have a creepy, post-apocalyptic vibe. Check out the photos below.
