Within the side by side 20 years, human beings could discover life on other planets.

It was this startling prediction—and the subsequent realization that kids sitting in simple schoolhouse classrooms today would be the first generation to know where exactly these extraterrestrials alive—that stoked David Aguilar's imagination.

In his latest children's book, Alien Worlds, Aguilar presents eight worlds, all modeled after Earth-similar planets and moons that really exist in the Milky Way milky way. Aguilar projects dissimilar temperature, gravity, light and h2o conditions onto these planets—all educated inferences based on the many stages Earth has gone through in its history. In "Sea Earth," for example, the planet's surface is predominantly water, much like Earth was 450 one thousand thousand years agone, whereas the desert-like "Dying World," with temperatures ranging from 85 to 140 degrees Fahrenheit, is a glimpse at what World could be similar virtually one and a one-half billion years from now.

And then, Aguilar addresses the bigger question: what will the inhabitants of these worlds look like?

"The popular image is that they expect similar usa. They look like humans: ii artillery, two legs, a olfactory organ, 2 optics, two ears and something is just slightly dissimilar. They've got bumps on their nose or pointy ears or imperial colored pare, and then consequently they are alien," says Aguilar, the manager of public affairs and science information at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. He first got into children's literature with his 2007 book Planets, Stars and Galaxies. "Sitting on my shelf side by side to my computer is an array of domestic dog-eared books, that I had as a child on space, robots and rockets submarines—nostalgic reminders of the heady ideas that whisked my heed abroad to other places and other possibilities," he says. "I desire to open young minds out there to the wonders, beauty and sheer awesomeness of their universe."

But, biologists might say that it is time that we drop Hollywood's humanoid view of extraterrestrials. In reality, Aguilar says, "Nosotros are going to find bizarre adaptations."

To illustrate Alien Worlds, Aguilar created models of marvelously imaginative aliens out of forest, plastic and clay. He photographed these models, and, then, in Photoshop, added colors, textures and other charismatic features.

Run into his cast of characters:

Beachrollers

(David Aguilar)

In Aguilar'southward fictional universe, a moon dubbed Chaos orbits Wakanda, a giant ice planet. The gravitational strength between the two celestial bodies creates huge ocean tides on the moon. Nosotros're talking mighty waves measuring more than than sixty feet alpine!

And then, how does a marine animal protect itself—especially if, like a turtle, it needs to come ashore to lay its eggs?

"I idea of the airbags in a car," says Aguilar. His beachrollers—crustacean-like critters—simply inflate an airbag around themselves. "Coming down those big waves, they roll right upwards to the beach, take care of whatever they are going to exercise, lay their eggs or reproduce, and so crawl back into the water and swim out."

Seapups

(David Aguilar)

Arclandia, a rocky water earth where temperatures fluctuate from -25 to 45 degrees Fahrenheit, is much like Earth during its ice ages. On it, Aguilar imagines in that location beingness a seal-like brute, with a peculiar way of hunting.

"Instead of jumping downwardly and biting something, it extends its very long tongue with fish hooks on it," he explains. "Information technology grabs an obaki [the ruby critter in its mouth, similar to an octopus] and reels it in simply similar somebody who went fishing for the day out on the ice."

Two big lung sacs on the seapups' blue bodies inflate and deflate to help them ascend and descend in the water. And, Aguilar says the "friendly beasts" like to tickle each other.

Coneheads

(David Aguilar)

Only two meg miles abroad from Arclandia is its twin planet, Venera, covered in thick, steamy clouds. "If you can meet 20 anxiety in front of y'all, it'southward a clear mean solar day," says Aguilar.

Given the brume, the illustrator dreams up 10-human foot tall coneheads that navigate their world by emitting and receiving odors. "The idea that there could be creatures that communicate using odors instead of words is quite viable," says Aguilar. "Ants communicate with odors. When an ant lays odors down in a trail, all of the other ants tin can follow information technology."

Cave Crawlers

(David Aguilar)

"Ane of the ways creatures volition deal with extreme heat is to go underground," says Aguilar. So, naturally, on Moros, his then-called "Dying World," where temperatures attain 140 degrees Fahrenheit, cave crawlers burrow into subterranean tunnels. These cantaloupe-sized vermin take multiple eyes and spiky feelers that allow them to flourish in the dark or dimly lit caverns.

Windcatchers

(David Aguilar)

"Imagine, if on Globe, i side was e'er facing the sun, and so information technology was hot and desert-like, similar the Heart East, and the contrary side was always facing away from the sun, so information technology was always in the dark, and it was like Antarctica," says Aguilar. This is Yelrihs, or the "Infrared World."

Nigh of the planet's life forms inhabit the twilight zone—a temperate band running from the North to South Pole. And yet, strong winds blow in this ring, where warm and absurd air from both sides of the planet converge.

Aguilar imagines giant windcatchers, with 30-human foot wingspans, that float in the cakewalk for weeks at a time, descending only to lay their eggs in bodies of water. "It would be like having the most gorgeous kites flying in your sky," he says.

Arrowheads

(David Aguilar)

Scuba diving on Siluriana, Aguilar'south "Ocean World," would be an incredible, and frightening, experience. The immature planet—resembling Earth 450 million years ago—is almost completely covered in h2o, with simply a few volcanoes and continents piercing the surface. And, the sea is full of ghastly predators.

An arrowhead, for example, is a formidable cross betwixt a whale and a shark. Weighing in at 100 tons, the beast is shaped like an arrow, with a triangular head and a stiff, slender body measuring well-nigh 70 feet. Its precipitous teeth are 14 inches long.

Despite the arrowhead's fangs, it is the mohawk, a spiky turtle-like creature, that will triumph in the clash, pictured hither. The mohawk'southward spines release a debilitating poison.

Netserefs

(David Aguilar)

A netseref sort of resembles a mushroom, except under its cap is a mass of tentacles.  The fauna, nigh eight feet in pinnacle, is known to cling to rocks. It leaves its perch, even so, to hunt, whipping its barbed tentacles at prey.

The reddish dwarf star that orbits Yelrihs beams infrared light onto the planet. Netserefs have eyes uniquely equipped for the weather. "Everything that they come across is in the infrared spectrum," says Aguilar.

The artist shows two little critters chosen preencatchers in this illustration, as the netseref would see them. In infrared, the preencatchers look similar colorful heat maps.

"I wanted to introduce to kids that eyes, on different creatures, practise not ever meet the same thing," explains Aguilar. "We know at present that dogs and we think cats come across a lot of ultraviolet light."

Temmets

(David Aguilar)

Aguilar styled an alien he calls a temmet subsequently an actual fossil of Hallucigenia, a small worm with spikes on its backs and tentacles for legs that lived on Earth during the Cambrian period, nearly 500 one thousand thousand years ago. "I love that body shape," he says, "and then I put information technology on a earth that had less gravity. It was much larger in size."

Temmets roam the cloudy planet Venera. The gentle giants have 8 legs and long snouts, for sucking h2o from lakes. In place of eyes, which would be futile in the foggy conditions, temets utilise sonar for wayfinding. Their spikes emit acoustic signals that bounce off of their surround.

"They make not bad pets," says Aguilar, playfully. "They will not retrieve a ball. That'south the only problem."
