cwnl: Quick Space Fact: The light hitting the earth right now is 30 thousand years old The energy in the sunlight we see today started out in the core of the Sun 30,000 years ago – it spent most of this time passing through the dense atoms that make the sun and just 8 minutes to reach us once it had left the Sun! The temperature at the core of the sun is 13,600,000 kelvins. All of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

cwnl: Quick Space Fact: We are moving through space at the rate of 530km a second Our Galaxy – the Milky Way is spinning at a rate of 225 kilometers per second. In addition, the galaxy is travelling through space at the rate of 305 kilometers per second. This means that we are traveling at a total speed of 530 kilometers (330 miles) per second. That means that in one minute you are about 19 thousand kilometers away from where you were. Scientists do not all agree on the speed with which the Milky Way is travelling – estimates range from 130 – 1,000 km/s. It should be said that Einstein’s theory of relativity, the velocity of any object through space is not meaningful. Via Listverse

"We were not born critical of existing society. There was a moment in our lives (or a month, or a year) when certain facts appeared before us, startled us, and then caused us to question beliefs that were strongly fixed in our consciousness-embedded there by years of family prejudices, orthodox schooling, imbibing of newspapers, radio, and television. This would seem to lead to a simple conclusion: that we all have an enormous responsibility to bring to the attention of others information they do not have, which has the potential of causing them to rethink long-held ideas."

Quick Space Fact: Did You Know Some of The Rocks Found on Earth are Actually Pieces of Mars? Both Earth and Mars have been slammed by large asteroids in the past. Although most of the debris kicked up by the impact falls back down on to the planet, some of it can be ejected so quickly that it escapes Mars entirely. These ejected meteorites can orbit the Solar System for millions of years before they finally crash down on other worlds. Some have crashed on Earth, and been identified by scientists. Tiny amounts of Mars’ atmosphere were trapped in the meteorites, and this is how scientists were able to study the Martian atmosphere before sending the first spacecraft. via NASA
