Spacefiles

Country: Britain
Added: 2006
Category: Science
Abstract: We human beings are actually the outcome during universe evaluation, and we are always using our wisdom to explore the foremost origin of our ancestors. In all ages, we human beings are always investigating the universe with curious and prostrate feelings. And with technology developing so fast, we still can only see only a tip of the iceberg.The more we explore, the more we feel puzzled about it, and that may be the most charming part of the universe.

    Spacefiles — Sun

    The seething face of a star, the only star in the universe we can glimpse like this — that star is the sun. It's an inferno spewing energy, heat and light. Without our local star — just 150 million kilometres distant — Earth would be a lifeless planet.

    Spacefiles — Inside Track

    Mercury is scorched and eradiated as no other planet. It is the smallest inner planet. Earth is 18 times as massive. Mercury's surface is the history of our solar system — from the earliest times.

    Spacefiles — Venus

    Today, this is the reality — a lifeless world with a dense and choking atmosphere and temperatures to melt lead. Venus is Earth gone wrong, a runaway greenhouse effect, a planet resurfaced as molten lava spewed from within, and covered everything. Venus, always shrouded in cloud, is the second planet from the sun, orbiting at a distance of 108 million kilometres.

    Spacefiles — Earth

    Rotating once a day, Earth takes a year to orbit the sun at a distance of 150 million kilometres. Earth is the largest inner planet, third from sun and first with a moon. Little more than a veneer, the top layer of Earth is the crust.

    Spacefiles — Moon

    Most likely, our planet had received the luckiest "double-whammy". Quickly — in no more than a year or two — a molten moon was orbiting a molten Earth. And at 20 times closer than today, the moon loomed huge in earthly skies.

    Spacefiles — Red Planet

    Mars today is a freezing waste — the only visible water, polar ice. Since life depends on it, evidence of water remains the great quest on Mars. With water the objective, an American probe, Mars Odyssey, slots into Martian orbit.

    Spacefiles — Asteroid

    Out here, in the great void before Jupiter, is the asteroid belt. It's a vast disk of rocks — a ring of so-called minor planets. Were it not for the disruptive pull of Jupiter, the asteroid belt might have formed a single planet. As it is, orbiting between Mars and Jupiter, the belt is an array of potential projectiles.

    Spacefiles — King Planet

    Jupiter has at least 60 moons — many, mere chunks of rock. With three rings of dust, as tenuous as gossamer, Jupiter is more than five times farther from the sun than is the Earth. It is the biggest planet. Earth would fit 12 times across a diameter of almost 143,000 kilometres.

    Spacefiles — Lord of the Rings

    Saturn, Lord of the rings, God of the harvest, is the sixth planet from the sun. Taking almost 30 years to complete a revolution, the second largest planet, Saturn's diameter is 120,000 kilometers, the width of nine earths. Saturn could accomodate earth, 752 times, far fewer than Jupiter. Saturn has a tilt. The Earth leans at 23.4 degrees, Saturn at 27.

    Spacefiles — Uranus and Neptune

    Uranus, a bland ball of gas, has rings. They were discovered when astronomers saw a star winking as it passed behind the planet. The rings — 11 at last count — are dark and narrow. Uranus is a giant. Four Earths would fit across its girth.

    Spacefiles — Pluto

    Dark, diminutive and cold — it's the farthest planet from the sun. The frontier world of Pluto — so obscure — it wasn't spotted until 1930, or its moon Charon until 1978.

    Spacefiles — Comet

    As the Earth turns on its axis and the constellations appear to move across the heavens, there's more to the night sky than the stars, the planets and the moon. There are visitors that can shine brightly for weeks, nomads whose unpredictability makes them all the more exotic. We know them as comets.

    Spacefiles — Night Sky

    Astronomy is an ancient science. We've always tried to make sense of the heavens. We built observatories to mark the movements of the stars, the planets, the moon, and the sun. We learnt the passage of the night sky.

    Spacefiles — Discovery

    True astronomy began in the Middle East. From 4,000BC, on towering ziggurats, the Babylonians charted the rising and setting of the sun. They grouped stars into patterns or constellations. They understood the cycles of the sky. These ancient observers knew that the sun, the moon and the planets moved against the background stars.

    Spacefiles — Whither?

    It's the late 21st century, and 500 kilometres above the surface of the Earth, we approach a space station. Perhaps we're tourists spending a weekend in orbit. Or maybe we're in transit to the moon or Mars, for that's where the space station scores — as a space port.

    Spacefiles — Orbit

    Planet Earth is a global village. And we communicate with anyone anywhere on Earth. Chatter and data are a network linked from orbit. From satellite — dishes catch radio and TV — we watch images from across the world and from worlds beyond, like Mars, kids' cartoons and global news. Telelecommunication bathes the planet.

    Spacefiles — High Hopes

    The International Space Station — is it nightmare or dream come true? As the largest structure ever assembled in Earth orbit, hopes were high for this toehold in the sky. Built by astronauts and cosmonauts, it's a human colony in the hostility of space.

    Spacefiles — Quest

    We humans are the result of the evolution of the matters in the universe, and humans use their intelligence to explore the history and environmental changes. We often ask: how big is the universe? Where does the matters in the universe come from? Besides the earth, does somewhere in the universe have life existence?

    Spacefiles — Zero to Zillions

    Since the 20th century, astronomers have established various kinds of universe models, on which the Big Bang theory has a great influence. They think an amazing big bang occurred at a broiling hot point around 14 billion years ago. After the Big Bang, it quickly expansed and gradually formed our universe of today.

    Spacefiles — Galaxy

    Supernovae are the lifeblood of our galaxy. Their debris and shockwaves help create stars like the sun. Their chemical elements are in every planet and every one of us. Our galaxy, the Milky Way — just one among the 50 billion galaxies — is believed to comprise the universe.

    Spacefiles — Telescope

    This telescope hasn't been built, nor its location decided. But when it comes on stream, the sheer power of its vision could revolutionize our perception of the universe. Till then, the most powerful telescope is here.

    Spacefiles — Far Out

    How do we measure the universe? Astronomers describe it in light years — the distance light travels in a year. Just think of it, in one year, light travels 9.5 million million kilometres. Such distances only make sense as "light years".

    Spacefiles — X-ray

    The cosmos in x-ray — wavelengths that see what optical astronomy cannot. X-rays reveal the hotspots of the universe — gases around supermassive black-holes, galaxies in collision, supernovae, stellar firestorms.

    Spacefiles — Black Hole

    A binary star system is a blue supergiant and its hungry companion, a black hole. Relentlessly, a plume of gas is drawn from the hapless giant. The black hole is an object so collapsed that nothing escapes its voracious gravity, not even light.

    Spacefiles — Yonder to Infinity

    The sphere of our cosmos — everything we know to exist in the universe — could be a dewdrop in an infinite mist. On strands of gossamer may be parallel universes. They would have time and space like us, but possibly different forms of matter. This idea is gaining credence among physicists. Already, they've accepted that rather than four dimensions, there are eleven.
