An Illustrated Map of Every Known Object in Space: Asteroids, Dwarf Planets, Black Holes & Much More

Name all the things in space in 20 minutes? Impossible, you say? Well if there’s anyone who might come close to summarizing the contents of the universe in less than half an hour, with the aid of a handy infographic map also available as a poster, it's physicist Dominic Walliman, who has explored other vast scientific regions in condensed, yet comprehensive maps on physics, mathematics, chemistry, biology, and computer science.

These are all academic disciplines with more or less clearly defined boundaries. But space? It’s potentially endless, a point Walliman grants up front. Space is “infinitely big and there are an infinite number of things in it," he says. However, these things can still be named and categorized, since “there are not an infinite number of different kinds of things.” We begin at home, so to speak, with the Earth, our Sun, the solar system (and a dog), and the planets: terrestrial, gas, and ice giant.

Asteroids, meteors, comets, dwarf planets, moons, the Kuyper Belt, Dort Cloud, and heliosphere, cosmic dust, black holes…. We’re only two minutes in and that’s a lot of things already—but it’s also a lot of kinds of things, and those kinds repeat over and over. The supermassive black hole at the center of the Milky Way may be a type representing a whole class of things “at the center of every galaxy."

The universe might contain an infinite number of stars—or a number so large it might as well be infinite. But that doesn’t mean we can’t extrapolate from the comparatively tiny number we’re able to observe as representative of general star behavior: from the “main sequence stars”—Red, Orange, and Yellow Dwarves (like our sun)—to blue giants to variable stars, which change in size and brightness.

Massive Red Giants explode into nebulae at the end of their 100 million to 2 billion year lives. They also, along with Red and Orange Dwarf stars, leave behind a core known as a White Dwarf, which will become a Black Dwarf, which does not exist yet because the universe it not old enough to have produced any. “White dwarves,” Walliman says, “will be the fate of 97% of the stars in the universe." The number of kinds of stars expands, we get into the different shapes galaxies can take, and learn about cosmic radiation and “mysteries.”

The project does not have the scope to include explanations of how we know about these kinds of objects, but Walliman does an excellent job of turning what may be the biggest picture imaginable into a thumbnail—or poster-sized (purchase here, download here)—outline of the universe. We cannot ask more from a twenty-minute video promising to name “Every Kind of Thing in Space.”

When Albert Einstein & Charlie Chaplin Met and Became Fast Famous Friends (1930)

Photo via Wikimedia Commons “You do not really understand something unless you can explain it to your grandmother,” goes a well-known quote attributed variously to Albert Einstein, Richard Feynman, and Ernest Rutherford. No matter who said it, “the sentiment… rings true,” writes Michelle Lavery , “for researchers in all disciplines from particle physics to ecopsychology.” As Feynman discovered during his many years of teaching , it could be “the motto of all professional communicators,” The Guardian ’s Russell Grossman writes , “and especially those who earn a living communicating the tricky business of science.” Einstein became one of the world’s great science communicators by choice, not necessity, and found ways to explain his complex theories to children and the elderly alike. But perhaps, if he’d had his way, he would rather have avoided words altogether, and preferred acrobatic feats of silent daring to get his message across. We might at least conclude so from his reverence f...

Howard Zinn’s Recommended Reading List for Activists Who Want to Change the World

Image by via Wikimedia Commons Back in college, I spotted A People’s History of the United States   in the bags and on the bookshelves of many a fellow undergraduate. By that time, Howard Zinn’s alternative telling of the American story had been popular reading material for a couple of decades, just as it presumably remains a couple more decades on. Even now, a dozen years after Zinn’s death, his ideas about how to approach U.S. history through non-standard points of view remain widely influential. Just last month, Radical Reads featured the reading list he originally drew up for the  Socialist Worker , pitched at “activists interested in making their own history.” Zinn’s recommendations naturally include the work of other historians, from Gary Nash’s Red, White and Black: The Peoples of Early America (“a pioneering work of ‘multiculturalism’ dealing with racial interactions in the colonial period”) to Vincent Harding’s There Is a River: The Black Struggle for ...

1,100 Delicate Drawings of Root Systems Reveals the Hidden World of Plants

We know that plants can inspire art. If you, personally, still require convincing on that point, just have a look at Elizabeth Twining’s Illustrations of the Natural Orders of Plants , the drawings of Ernst Heinrich Haeckel , Elizabeth Blackwell’s  A Curious Herbal , and Nancy Anne Kingsbury Wollstonecraft’s Specimens of the Plants and Fruits of the Island of Cuba — not to mention the paintings of Georgia O’ Keeffe — all previously featured here on Open Culture. But those works concern themselves only with plant life as it exists above ground. What goes on down below, underneath the soil? That you can see for yourself — and without having to pull up one of our fine flowering (or non-flowering) friends to do so — at Wageningen University’s online archive of root system drawings . “The outcome of 40 years of  root system excavations in Europe,” says that site, the collection contains 1,180 diagrams of species from  Abies alba (best known today as a kind of Christmas t...
