This secretion has anti-bacterial components as well. Hippos still need to stay well hydrated, which is why you probably find them in water or covered in mud! Why are you seeing a new color when the wheel spins? The colors are spinning at such a rate that your brain is unable to process them as the individual colors that are on the wheel.
Instead, your brain takes a shortcut and creates the secondary colors. Check out our math If you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly and we're speaking very roughly here 7. If we have a Hubble telescope and a calculator, we can count distant galaxies, faint stars, red dwarfs, everything ever recorded in the sky.
The population of stars jumps enormously, to 70 thousand million, million, million stars in the observable universe a estimate , so that we've got multiple stars for every grain of sand.
Male seahorses have a pouch on the ventral, or front-facing, side of its tail. For the next days, the male carries the eggs until they baby seahorses emerge. An astronaut's burps are different than those experienced on Earth.
If an astronaut does burp in space, it comes out as a wet burp! Over the course of one year, this will amount to 16 million storms across the Earth! Caffeine withdrawal is a real condition with neurochemical causes. Common symptoms include headache, fatigue, difficulty concentrating, and dysphoric mood. Saturn is predominantly comprised of hydrogen and helium gas, giving it an overall density lower than that of liquid water. While mammals have seven neck vertebrae, sloths have eight or nine.
The reasons for the extra vertebrae are not clear, but might contribute to their ability to turn their necks farther than other mammals.
That's all of the facts for now, but we have plenty more to discover! Check out our cooler than cool exhibit halls to amaze your brain even more! Explore The Museum. A day on Venus lasts longer than a year on Venus. Everything you see happened in the past. Footprints are still on the moon. Honey never spoils.
Our body is just a collection of atoms studying itself. A single bolt of lightning could contain enough energy to cook 20, pieces of toast.
Hummingbirds are the only birds that can fly backwards and upside down. On Saturn and Jupiter, it can rain diamonds. Peregrine falcons fly over 3 times faster than cheetahs run. An average cumulus cloud weighs more than 70 adult T. Our state reptile, the Texas Horned Lizard, can squirt blood from its eye sockets. Butterflies taste food with their feet. The first airplane flight was only 65 years before the moon landing. Only female mosquitoes drink blood. The brain named itself.
Had to think about that one, didn't you? Lava can flow as fast as a greyhound runs. The North Pole has one sunrise each year. Dinosaurs are not really extinct. Make some noise! Try It! You can start a fire with ice. Rainforests are home to over half of Earth's animals. The match was invented after the lighter. You are always looking at your nose, your brain just chooses to ignore it. At a standstill, you are actually traveling at 2. Snails have thousands of teeth. That means that a day on Venus is a little longer than a year on Venus.
Since the day and year lengths are similar, one day on Venus is not like a day on Earth. Here, the Sun rises and sets once each day. But on Venus, the Sun rises every Earth days. That means the Sun rises two times during each year on Venus, even though it is still the same day on Venus! And because Venus rotates backwards, the Sun rises in the west and sets in the east. This is a combination of images taken by the Magellan spacecraft.
The colors have been altered so you can see all the differences in Venus's surface. Magellan used radar to get information about the surface of Venus, which we can't normally see because of the thick, cloudy atmosphere. All About Venus. The swirling clouds covering Venus also add to its brilliance.
A transit occurs when a planet passes between the sun and the Earth. Transits of Venus occur in paired cycles with eight years in between the pairs. The first pair observed after the invention of the telescope were in and The most recent pair occurred in and Another transit isn't expected until Venus, although named for the goddess of beauty, is a vicious place.
The atmosphere is a layer of dense clouds that contain water vapor and sulfuric acid. The surface of the planet is marked with craters, extinct volcanoes and shapes that would be continents if the planet had any water to make oceans. Temperatures on Venus hover around degrees Fahrenheit degrees Celsius with little change in temperature between day and night thanks to the thick blanket of insulating clouds.
Based in Portland, Ore. Her articles have appeared in magazines such as "Herb Companion" and "Northwest Travel" and she is the author of six books.
