Neil deGrasse Tyson is America's preeminent badass astrophysicist. He's a passionate advocate for science, NASA, and education. He's also well-known for a little incident involving Pluto, and he's not afraid to chide Hollywood about their scientifically implausible missteps. Plus, the man holds 20 honorary doctorates (in addition to his real one) and coined the term "Manhattanhenge" to describe the two yearly occasions when the sunset perfectly aligns with Manhattan's grid. In honor of his 60th birthday, here are 10 of our favorite Neil deGrasse Tyson quotes.

1. ON SCIENCE

"The good thing about science is that it's true whether or not you believe in it."

—From Real Time with Bill Maher

2. ON NASA FUNDING

"As a fraction of your tax dollar today, what is the total cost of all spaceborne telescopes, planetary probes, the rovers on Mars, the International Space Station, the space shuttle, telescopes yet to orbit, and missions yet to fly?' Answer: one-half of one percent of each tax dollar. Half a penny. I’d prefer it were more: perhaps two cents on the dollar. Even during the storied Apollo era, peak NASA spending amounted to little more than four cents on the tax dollar."

—From Space Chronicles

3. ON NAMING NATURAL PHENOMENA

"Once upon a time, people identified the god Neptune as the source of storms at sea. Today we call these storms hurricanes … The only people who still call hurricanes acts of God are the people who write insurance forms."

—From Death by Black Hole

4. ON THE BENEFITS OF TECHNOLOGY INVENTED FOR USE IN SPACE

"Countless women are alive today because of ideas stimulated by a design flaw in the Hubble Space Telescope."

(Editor's note: technology used to repair the Hubble Space Telescope's optical problems led to improved technology for breast cancer detection.)

—From Space Chronicles

5. ON THE DEMOTION OF PLUTO FROM PLANET STATUS

"I knew Pluto was popular among elementary schoolkids, but I had no idea they would mobilize into a 'Save Pluto' campaign. I now have a drawer full of hate letters from hundreds of elementary schoolchildren (with supportive cover letters from their science teachers) pleading with me to reverse my stance on Pluto. The file includes a photograph of the entire third grade of a school posing on their front steps and holding up a banner proclaiming, 'Dr. Tyson—Pluto is a Planet!'"

—From The Sky Is Not the Limit

6. ON JAMES CAMERON'S TITANIC

"In [Titanic], the stars above the ship bear no correspondence to any constellations in a real sky. Worse yet, while the heroine bobs … we are treated to her view of this Hollywood sky—one where the stars on the right half of the scene trace the mirror image of the stars in the left half. How lazy can you get?"

—From Death by Black Hole

7. ON DEATH BY ASTEROID

"On Friday the 13th, April 2029, an asteroid large enough to fill the Rose Bowl as though it were an egg cup will fly so close to Earth that it will dip below the altitude of our communication satellites. We did not name this asteroid Bambi. Instead, we named it Apophis, after the Egyptian god of darkness and death."

—From Space Chronicles

8. ON THE MOTIVATIONS BEHIND AMERICA'S MOONSHOT

"[L]et us not fool ourselves into thinking we went to the Moon because we are pioneers, or discoverers, or adventurers. We went to the Moon because it was the militaristically expedient thing to do."

—From The Sky Is Not the Limit

9. ON INTELLIGENT LIFE (OR THE LACK THEREOF)

"Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life."

10. PRACTICAL ADVICE IN THE EVENT OF ALIEN CONTACT

"[I]f an alien lands on your front lawn and extends an appendage as a gesture of greeting, before you get friendly, toss it an eightball. If the appendage explodes, then the alien was probably made of antimatter. If not, then you can proceed to take it to your leader."

—From Death by Black Hole

11 Easy Ways to Be Greener on Earth Day

Kermit got it all wrong: It is easy being green. Committing to go green doesn’t have to mean a 10-mile walk to work or abiding by "if it’s yellow, let it mellow"—you can make a difference by making small adjustments that add up to big change. Here are 11 ideas to get you started for Earth Day.

1. Use your dishwasher to go green.

It may seem counterintuitive, but your dishwasher is way more energy- and water-efficient at washing dishes than you are, as long as you’re running a full dishwasher. According to one German study, dishwashers use half of the energy and a sixth of the water, not to mention less soap. So, don’t feel guilty about skipping the sink of sudsy water, or about not pre-rinsing before loading up the machine—you’re actually doing the environment a favor by firing up your dishwasher.

2. Switch to online bill paying and use less paper.

Not only is it convenient to pay all of your bills with a click or two, it’s also an easy way to go green. One study found that the average U.S. household receives 19 bills and statements from credit card companies, banks, and utilities every month. By switching to online statements and online bill pay, each American household could save 6.6 pounds of paper per year, save 0.08 trees, and not produce 171 pounds of greenhouse gases. Not bad for simply clicking a few "receive online statements" boxes.

3. Opt out of junk mail and catalogs.

While you’re paring down the amount of stuff that arrives daily in your mailbox, visit Catalog Choice to opt out of various mailers you don’t want to receive. So far, the nonprofit organization says they have saved more than 500,000 trees, over 1 billion pounds of greenhouse gas, more than 400 million pounds of solid waste, and approximately 3.5 billion gallons of water.

4. Plant a tree so Earth Day is Every Day.

Planting trees is obviously great for the environment, but if you’re strategic about it, it can help you reduce your energy costs and use less fossil fuel. According to ArborDay.org, planting large deciduous trees on the east, west, and northwest sides of your house can shade and cool your home during the warmer months, even slashing your air conditioning costs by up to 35 percent.

5. Turn off the tap while you're standing at the sink.

If you leave the tap running while you tend to your pearly whites, you’re wasting approximately 200 gallons of water a month. Just turn the tap on when you need to wet your brush or rinse, instead of letting H20 pour uselessly down the drain. The same goes for anyone who shaves with the water running.

6. Go thrifting for clothes and housewares.

Take some advice from your old pal Macklemore and hit up some thrift shops—and that goes for whether you’re getting rid of clutter or adding more to your home. Buying and donating to thrift stores and second-hand shops means you’re recycling, supporting your local economy, and saving money. In fact, by some estimates, every item of clothing donated reduces 27 pounds of carbon emissions.

7. Get a houseplant to clear the air.

And grab a little guy for your desk at work, too. House plants and desk plants have been proven to improve your mood and raise productivity, but they also purify the air by removing volatile organic compounds (VOCs) found in homes and offices. They also absorb carbon dioxide and increase the humidity. Low-maintenance plants include pothos, spider plants, jade, various succulents, and peace lilies.

8. Get scrappy with Art and crafts.

Cut up paper that has only been used on one side and use it to scribble reminders, notes, grocery lists, etc. Or flip it over for any kids you know to color on. (You can color on it, too, if you want.)

9. Put your caffeine fix to work for the Earth.

Your coffee likely traveled thousands of miles to arrive in your pantry, so get good use out of it. Use your grounds to mulch plants that love acidic soil, like roses, evergreens, and rhododendrons. If your garden problems tend to be less about the dirt and more about the things that live in it, certain garden denizens hate coffee—namely ants, slugs, and snails. Sprinkle grounds in problem areas to deter them.

10. Enlighten yourself to Energy Savings.

Compact fluorescent bulbs (CFLs—the spiral light bulbs) may cost more upfront, but they’ll save up to $57 over the life of the bulb. More importantly, they use 70 percent less energy than traditional bulbs and installing them is as easy as screwing in a light bulb. (Insert joke here.)

11. Make tracks instead of short car trips.

You don't have to cut out your daily driving entirely, but when you only have a few blocks, or perhaps just a mile or two to travel and don't need to transport anything bulky, consider walking or hopping on your bike. Walking on those short trips generates less than a quarter of the greenhouse gasses that are emitted by driving the same distance.

20 Black-and-White Facts About Penguins

Who is a penguin's favorite family member? Aunt Arctica! 

We kid! But seven of the 17 species of penguins can be found on the southernmost continent. Here are 20 more fun facts about these adorable tuxedoed birds. 

1. All 17 species of penguins are found exclusively in the Southern Hemisphere.

2. Emperor Penguins are the tallest species, standing nearly 4 feet tall. The smallest is the Little Blue Penguin, which is only about 16 inches.

3. The fastest species is the Gentoo Penguin, which can reach swimming speeds up to 22 mph.

4. A penguin's striking coloring is a matter of camouflage; from above, its black back blends into the murky depths of the ocean. From below, its white belly is hidden against the bright surface.

5. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs.

6. Penguins ingest a lot of seawater while hunting for fish, but a special gland behind their eyes—the supraorbital gland—filters out the saltwater from their blood stream. Penguins excrete it through their beaks, or by sneezing.

7. Unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt.

8. All but two species of penguins breed in large colonies of up to one thousand birds.

9. It varies by species, but many penguins will mate with the same member of the opposite sex season after season.

10. Similarly, most species are also loyal to their exact nesting site, often returning to the same rookery in which they were born.

11. Some species create nests for their eggs out of pebbles and loose feathers. Emperor Penguins are an exception: They incubate a single egg each breeding season on the top of their feet. Under a loose fold of skin is a featherless area with a concentration of blood vessels that keeps the egg warm.

12. In some species, it is the male penguin which incubates the eggs while females leave to hunt for weeks at a time. Because of this, pudgy males—with enough fat storage to survive weeks without eating—are most desirable.

13. Penguin parents—both male and female—care for their young for several months until the chicks are strong enough to hunt for food on their own.

14. If a female Emperor Penguin's baby dies, she will often "kidnap" an unrelated chick.

15. Despite their lack of visible ears, penguins have excellent hearing and rely on distinct calls to identify their mates when returning to the crowded breeding grounds.

16. The first published account of penguins comes from Antonio Pigafetta, who was aboard Ferdinand Magellan's first circumnavigation of the globe in 1520. They spotted the animals near what was probably Punta Tombo in Argentina. (He called them "strange geese.")

17. An earlier, anonymous diary entry from Vasco da Gama's 1497 voyage around the Cape of Good Hope makes mention of flightless birds as large as ducks.

18. Because they aren't used to danger from animals on solid ground, wild penguins exhibit no particular fear of human tourists.

19. Unlike most sea mammals—which rely on blubber to stay warm—penguins survive because their feathers trap a layer of warm air next to the skin that serves as insulation, especially when they start generating muscular heat by swimming around.

20. In the 16th century, the word penguin actually referred to great auks (scientific name: Pinguinus impennis), a now-extinct species that inhabited the seas around eastern Canada. When explorers traveled to the Southern Hemisphere, they saw black and white birds that resembled auks, and called them penguins.
