  • The Brightest Supernova Ever Recorded Lit Up The Sky On This Day in 1006

    Stars have been born and also dying ever since God created this universe - you can not have life unless something dies - that is the lesson of the seed - unless a seed falls to the ground and dies it can not bring forth life

    The Brightest Supernova Ever Recorded Lit Up The Sky On This Day in 1006

    Heated gas (red) and electrons (blue) are all that remains of the brightest supernova in recorded history.

    Over a thousand years ago today, people around the world looked up into the night sky and saw something wonderful and terrifying. A piece of the night sky in the constellation Lupus which had previously been dark suddenly flared with light sixteen times brighter than Venus. Chinese astronomers called it a "guest star," but today we know that the bright object which briefly lit the night sky beginning on April 30, 1006, was a supernova -- the brightest in recorded history.

    Because the 1006 supernova was so bright, it's also one of the most widely documented astronomical events in history, even though it happened 600 years before the invention of the telescope. Observers as far north as Switzerland and stretching across a swath of the globe from Egypt to Iraq and east to China and Japan, recorded the "guest star" and its appearance. The 1006 supernova may even be depicted in a petroglyph in Arizona, made by the Hohokam people, although that interpretation of a white circle with lines radiating from it has sparked some debate among archaeologists.

    Those descriptions, many of which are remarkably detailed for observers working without telescopes or imaging instruments, give modern astronomers a lot of information to help them reconstruct what really lit up the sky in 1006.



    An astronomer at the Abbey of St. Gall in Switzerland reported that the supernova's brightness varied over the three months it was visible, sometimes dimming or fading altogether before flaring to life again. Eventually it disappeared and then reappeared, more dimly, for another year and a half. Egyptian astronomer and astrologer Ali ibn Ridwan estimated that the light source covered about two to three times as much of the visible sky as Venus, and compared its brightness to that of the quarter Moon. Chinese astrologer Zhou Keming and others recorded the supernova's position in the sky with great precision.

    Based on those descriptions, modern astronomers estimate that the 1006 supernova was a type 1a - the kind that happens in binary star systems in which at least one of the stars is a white dwarf which reignites briefly before dying in a fiery cataclysm. In this case, the star whose death brightened the early medieval sky was 7200 light years away.

    That means the supernova really happened about 8.200 years ago, but it took until 1006 for the light of the cosmic explosion to reach Earth. Today, SN 1006 isn't visible with the naked eye, but telescopes like the Chandra X-ray observator can still see it as expanding ball of gas, slowly cooling and fading, which will eventually contribute to the formation of new stars.

    Calculating the distance from the earth to stars that are near us is a simple Trig calculation. They can measure the angle to the star from the earth when it is on one side of its orbit around the sun and then measure the angle from the earth when it is on the other side of the orbit. We know the distance from one side of the orbit to the other, so it is a simple trig calculation to find the distance to that star.

    God has created light and the light coming from every element is different. So we can know what elements are in each star. We can identify different kinds of stars from the different kinds of light coming from them. Several kinds of stars have exactly the same amount of light coming from them. We call these "Standard Candles". We can find these Standard Candles and measure how bright the light is coming from them to the earth. We then can tell how near or far away from the earth these standard candles are.

    This star that had a supernova back in the year 1006 was seen by many men from all different locations on the earth. Some recorded the position of this supernova in the sky with great precision. So today they have located this star that was the source of the supernova. They have measured the distance of the remnants of this star from the earth and it is 7200 light years from the earth. We know the speed of light and so we can know when this star had the supernova. It took the light 7200 years to get to the earth.

    So we know that our galaxy was here 7200 years BEFORE the year 1006. So that is about 8200 years ago. God is not trying to deceive us. Instead God reveals to truth to those who seek The Truth.

    God has told us that His creation reveals The Truth:

    Psalm 19 (NIV)

    Psalm 19

    For the director of music. A psalm of David.


    1The heavens declare the glory of God;
    the skies proclaim the work of his hands.
    2 Day after day they pour forth speech;
    night after night they reveal knowledge.
    3 They have no speech, they use no words;
    no sound is heard from them.
    4 Yet their voice goes out into all the earth,
    their words to the ends of the world.
    So God's creation has revealed knowledge to mankind and it reveals that the universe is far older than 6000 earth years. God is in no hurry. A few billion years in nothing to Him. The Holy Scriptures do not say that the days of creation were earth days. In fact they were not about time, but about the coming of light.

      I will post this one more day for those who have not seen it yet.
