Visualizing Gravity Wells - infographic comic

Another great new infographic comic from xkcd.com.  A mix of real science and humor, this one plays on the words "gravity well" by visualizing the strength of each planets gravity as the depth of a crater scaled to Earth's surface gravity.

The chart shows the "depth" of various solar system gravity wells.

Each well is scaled such that rising out of a physical well of that depth - in constant Earth surface gravity - would take the same energy as escaping that planet's gravity in reality.

Bill Nye Videos on the Scale of the Solar System

Two videos from Bill Nye the Science Guy showing the size and scale of the planets and the Sun.  He may have done similar examples, but these are the two I know about.  The one above (Planets & Moon) starts at about 4:00 into the video, and the one below (Outer Space) starts at about 2:00.  "Outer Space is HUGE!"



Thanks to @DannyDougherty on Twitter for sharing!

Scale Model of the Solar System

The Scale Model of the Solar System (from phrenopolis.com) shows both the relative sizes of the planets and the Sun as well as representing the distances from the Sun on the same scale.  This image is huge (just over half a mile wide), and as you can imagine mostly black.

This page shows a scale model of the solar system, shrunken down to the point where the Sun, normally more than eight hundred thousand miles across, is the size you see it here. The planets are shown in corresponding scale. Unlike most models, which are compressed for viewing convenience, the planets here are also shown at their true-to-scale average distances from the Sun. That makes this page rather large - on an ordinary 72 dpi monitor it's just over half a mile wide, making it possibly one of the largest pages on the web. This means you'll have to do a bit of scrolling if you want to find the planets, but don't despair. They are reasonably bright and labeled, so you can probably catch them flashing by in the blackness even if you are scrolling fairly fast.

Probes in the Universe - cool interactive infographic

Space Probes is a very well-done interactive graphic about all of the space probes we have launched, visually placing the probes in orbit around the object they are observing.  You can move around the 3-D space with the keyboard controls, change the date range with the sliders on the bottom or go directly to a particular probe from the list on the right that is group by planet or object they are around.  When you mouse-over a particular probe you get more details and an image.

The article and the infographic are in Portuguese from Brazil, so I took the liberty of using the Google Translator for a little help.

The infographic "Space Probes" Super, produced by the team of Internet Editora Abril Jovem, took the silver medal in the category Online Malofiej, top prize in the world of computer graphics.

Thanks to Daniel for the link and a little more information:

It won Malofiej's silver medal (first place, no gold medal) this year. 

It's an infographic about all space probes launched until the date it was published (except Earth probes, which are too many). The info has information about each probe, including the organization(s) that sent it, the target planet(s) (or moons, asteroids, comets and the sun), launch date and mission details, as well as pictures for most of them. User can navigate through our Solar System using the mouse and/or keyboard. It's also possible to know the details of Mars Science Laboratory, the next NASA probe to visit the red planet. The info is in Portuguese, but anyone can understand it's features and learn a little bit about space exploration so far.

Planets, a Solar System Visualizer

Check out Planets, an interactive solar system visualizer.  It lets you change the focal point so you can see the planetary motions as if you were standing on any of the planets.  A great way to understand retrograde motion.

Thanks Paul, for the link.

Dark Matter distorts light

From NASA.gov, an image depicting how Dark Matter (in red) distorts light from distant galaxies as it travels across the universe.

Explanation: Is the distant universe really what it appears to be? Astronomers hope not. Intervening dark matter, which is normally invisible, might show its presence by distorting images originating in the distance universe, much the way an old window distorts images originating on the other side.

GE Ecomagination Blueprint Ads

GE is running The Blueprint Series of five print ads combining photos with an overlay of infographics. This works really nicely because they kept the infographics relatively simple.

Timeline of Space Exploration

Newsweek has a cool interactive timeline showing all of the 150+ missions sent into space. Its organized by year (of course) but also by object of destination (planet/moon/asteroid). You can click on a year and zoom in to see specific dates of each launch. Rolling your mouse over any dot gives you the name and details of the mission.

Potential Solar Energy

Submitted by a reader (thanks Louis), this infographic is from Good Magazine. Of course there isn't actually a way to capture ALL of the light from the sun, but it is indicative that we should be able to capture more than we do.

Check out this link at Good Magazine for a few other infographics too.

The Elegant Universe

Following my earlier post on Imagining the Tenth Dimension, I found that NOVA has put the entire 3-hour show The Elegant Universe on their website.


The show is full of different visual methods to visual strings, gravity, the scale of particles and multiple dimensions. Brian Greene really did a fantastic job with this show based on his book on the same name.

The Cosmic Calendar

This last December was the 10th anniversary of Carl Sagan's death. One of his most popular episodes of Cosmos was titled The Dragons of Eden where he first described his Cosmic Calendar. This website from discovery.com has a simple image showing the Cosmic Calendar as Carl described it. A few websites are selling posters of the Cosmic Calendar, like AllPosters.com.

The premise is that if you compress the entire history of the universe into a calendar year, homo sapiens only exist in the last 6 minutes, and the last second represents the last 400+ years of human history.

You can see Cosmos, and hear Carl describe it on YouTube here:

Bodies in the Solar System

Another great infographic on kokogiak.com showing the relative size of large objects (88 of them, at least over 200 miles in diameter) in our solar system. The largest (of course) being the sun down to the smallest, which is Davida, an asteroid 203 miles in diameter.

The Size of Our World

This is a simple, but great infographic. How big are the planets? How big is our Sun? How small is the Earth? The site shows five different images on increasingly larger scales.

No numbers or measurements. Easy to understand. So simple, yet SO informative.
