How Earth Sounds from Space

A NOTE TO EVERYONE POSTING HERE!
-------------------------------

OK, first of all I had no idea this video was going to be this popular. Pretty exciting stuff. Anyways, there's alot of arguing on here about sound in space. Obviously sound needs a medium to pass through, to vibrate through so that it can carry the sound waves. Space has no air, and therefore cannot project sound in audible wave form. As it says in the description, these sounds are not from satellites zooming around the earth with a normal microphone. Sohpisticated instruments can detect the different sonic vibrations going on in the planet GENERALLY. So what you are hearing is not what it would be like if you just stuck an ear out the window of a space ship. First of all you would probably either die or go deaf in that ear for the rest of your life because of the pressure of the vaccum. What the remote sensors on the sattellite are doing is analyzing different radio frequencies coming off the surface of the earth and converting it into audible soundwaves for you and I to hear. So you're not hearing whales, you're not hearing cars or even wind. You're merely hearing the general frequencies of the Earth in an audible format.

here's where i got the sound file

Why Mars Died, and Earth Lived

This video explores the most basic question of all: why we explore space? Be sure to experience the visual spectacle in full HD, 1080P.

The Mars rover, Curiosity, is the latest in a long line of missions to Mars: landers sent to scoop its soil and study its rocks, orbiters sent to map its valleys and ridges.

They are all asking the same question. Did liquid water once flow on this dry and dusty world? Did it support life in any form? And are there remnants left to find? The science that comes out of these missions may help answer a much larger, more philosophical question.

Is our planet Earth the norm, in a galaxy run through with life-bearing planets? Or is Earth a rare gem, with a unique make-up and history that allowed it to give rise to living things? On Mars, Curiosity has spotted pebbles and other rocks commonly associated with flowing water.

It found them down stream on what appears to be an ancient river fan, where water flowed down into Gale Crater. This shows that at some point in the past, Mars had an atmosphere, cloudy skies, and liquid water flowing. So what could have turned it into the desolate world we know today?

One process that very likely played a role goes by the unscientific name, "sputtering." Like the other planets in our solar system, Mars is lashed by high-energy photons from the Sun. When one of these photons enters the atmosphere of a planet, it can crash into a molecule, knocking loose an electron and turning it into an ion. The solar wind brings something else: a giant magnetic field. When part of the field grazes the planet, it can attract ions and launch them out into space.

Another part might fling ions right into the atmosphere at up to a thousand kilometers per second. The ions crash into other molecules, sending them in all directions like balls in a game of pool. Over billions of years, this process could have literally stripped Mars of its atmosphere, especially in the early life of the solar system when the solar wind was more intense than it is today.

Sputtering has actually been spotted directly on another dead planet, Venus. The Venus Express mission found that solar winds are steadily stripping off lighter molecules of hydrogen and oxygen. They escape the planet on the night side... then ride solar breezes on out into space.

This process has left Venus with an atmosphere dominated by carbon dioxide gas... a heat trapping compound that has helped send surface temperatures up to around 400 degrees Celsius. The loss of Venus' atmosphere likely took place over millions of years, especially during solar outbursts known as coronal mass ejections.

If these massive blast waves stripped Venus and Mars of an atmosphere capable of supporting life how did Earth avoid the same grim fate? We can see the answer as the solar storm approaches earth. Our planet has what Mars and Venus lack - a powerful magnetic field generated deep within its core.

This protective shield deflects many of the high-energy particles launched by the Sun. In fact, that's just our first line of defense. Much of the solar energy that gets through is reflected back to space by clouds, ice, and snow.

The energy that earth absorbs is just enough to power a remarkable planetary engine: the climate. It's set in motion by the uneveness of solar heating, due in part to the cycles of day and night, and the seasons. That causes warm, tropical winds to blow toward the poles, and cold polar air toward the equator.

Wind currents drive surface ocean currents. This computer simulation shows the Gulf Stream winding its way along the coast of North America. This great ocean river carries enough heat energy to power the industrial world a hundred times over.

It breaks down in massive whirlpools that spread warm tropical waters over northern seas. Below the surface, they mix with cold deep currents that swirl around undersea ledges and mountains. Earth's climate engine has countless moving parts: tides and terrain, cross winds and currents -- all working to equalize temperatures around the globe.

Over time, earth developed a carbon cycle and an effective means of regulating green house gases. In our galaxy, are still-born worlds like Mars the norm? Or in Earth, has Nature crafted a prototype for its greatest experiment... Life?

What If We Detonated a Nuclear Bomb on the Moon?

The U.S. Air Force considered trying to detonate a nuclear device on the moon during the late 1950s. A physicist who worked on the project said a single explosion would have been "microscopic," with little impact. But what if the plans had been bigger—do we have enough nuclear weapons to push the moon out of orbit?

Not even close. Depending on where the detonation happened, sending the moon careening away from Earth would take somewhere between 10 billion and 10 trillion megatons of TNT. The most powerful nuclear device ever detonated, the Soviet Union's "Tsar Bomba," yielded the energy equivalent of 50 megatons of TNT. The current nuclear arsenal of the world could produce less than 7,000 megatons.

The moon is constantly edging away from us, though, without any human intervention. The moon's pull drags a portion of the Earth's water out of its natural position, creating bulges at each end of the planet. As Earth rotates, these bulges exert force on the moon, adding to its kinetic energy and making its orbit grow larger. On average, the moon floats 3 or 4 centimeters further away every year.

Life without the moon would be strange in the near term and disastrous in the long term. If the stabilizing influence of the moon disappeared, the Earth would begin to teeter dramatically on its axis, and seasons would no longer be constant. Over the long term, it's possible the Earth could topple over, as apparently happened to Uranus, which orbits the sun on its side.

Earth 100 Million Years From Now

Earth's landmasses were not always what they are today. Continents formed as Earth's crustal plates shifted and collided over long periods of time. This video shows how today's continents are thought to have evolved over the last 600 million years, and where they'll end up in the next 100 million years.

Cosmic Journeys : The Largest Black Holes in the Universe


Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?

A new era in astronomy has revealed a universe long hidden to us. High-tech instruments sent into space have been tuned to sense high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes and do not penetrate our atmosphere. On the ground, precision telescopes are equipped with technologies that allow them to cancel out the blurring effects of the atmosphere. They are peering into the far reaches of the universe, and into distant caldrons of light and energy. In some distant galaxies, astronomers are now finding evidence that space and time are being shattered by eruptions so vast they boggle the mind.

We are just beginning to understand the impact these outbursts have had on the universe: On the shapes of galaxies, the spread of elements that make up stars and planets, and ultimately the very existence of Earth. The discovery of what causes these eruptions has led to a new understanding of cosmic history. Back in 1995, the Hubble space telescope was enlisted to begin filling in the details of that history. Astronomers selected tiny regions in the sky, between the stars. For days at a time, they focused Hubble's gaze on remote regions of the universe.

These hubble Deep Field images offered incredibly clear views of the cosmos in its infancy. What drew astronomers' attention were the tiniest galaxies, covering only a few pixels on Hubble's detector. Most of them do not have the grand spiral or elliptical shapes of large galaxies we see close to us today.

Instead, they are irregular, scrappy collections of stars. The Hubble Deep Field confirmed a long-standing idea that the universe must have evolved in a series of building blocks, with small galaxies gradually merging and assembling into larger ones.

Rainbow Cake: How to Make a Rainbow Cake

How to make a rainbow cake covered with rainbow frosting.

UPDATE: I have been getting a lot of questions regarding exactly how much cake batter and buttercream that should be used for this recipe. If you want a cake as large as the one that I made, you will need 1.5 amounts of the batter recipe linked below and at LEAST double the amount of the buttercream. If you are using a box mix, I would use two boxes (mixed according to the package) and only use about 1.5 amounts of the batter that is made. Hope that helps you all out!
