Dan Phiffer found this image on a message board (it's by Adam Nieman / Science Photo Library), and by his calculations, he says it's accurate.
Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc.
Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth.

Conceptual computer artwork of the total volume of water on Earth (left) and of air in the Earth's atmosphere (right) shown as spheres (blue and pink). The spheres show how finite water and air supplies are. The water sphere measures 1390 kilometres across and has a volume of 1.4 billion cubic kilometres. This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the atmosphere. The air sphere measures 1999 kilometres across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometres of the atmosphere.

Scientists combined multiple imaging technologies to deliver an unprecedented 3D view inside the body of crawling cancer cells, spinal cord circuit development, and immune cells traveling within a zebrafish (above). Nobel laureate Eric Betzig and his colleagues at the Howard Hughes Medical Institute integrate a technology called lattice light sheet microscopy with adaptive optics resulting […]
Landru79 created this spectacular GIF from images captured in 2016 on the surface of Comet 67P/Churyumov–Gerasimenko by the European Space Agency lander Philae deployed by the Rosetta probe. The video is significantly sped up, compressing 25 minutes into a few seconds of intense action. But what exactly are we looking at in this pandemonium? From […]
Using DNA to store digital data has been a classic forecast in infotech futurism for more than two decades. The basic concept is that you could synthesize strands of DNA encoded with digital information and then decode it with DNA sequencing techniques. While several amazing experiments have demonstrated that DNA data storage is possible, it’s […]
Our computers are home to a myriad of files and documents, many of which contain sensitive information. While storing this data on your computer is convenient, it’s not exactly safe, and with news headlines highlighting data leaks and ransomware attacks on what seems like a daily basis, moving them to a safer location is a […]
Total versatility isn’t something you’d typically find in a telescope. While magnification tech has come a long way, most telescopes are designed to either gaze upon the stars or view the landscapes beneath them. The Omegon Maksutov Telescope MightyMak 60 lets you do both, and thanks to its compact design, you can easily incorporate some sightseeing into […]
The web is an invaluable tool for connecting small businesses with their target audiences. However, when it comes to building a website and marketing online, the learning curve can be steep if you’re doing it on your own. The WordPress Essentials Lifetime Bundle can help you out by getting you up to speed with the platform […]
