Tickle your brain with these interesting facts about space

  1. The oldest and therefore furthest known galaxy we have discovered is over 13.7 billion light years away. It’s called z8_GND_5296. The light has taken so long to reach us that the star which collapsed to form the gas that Sun is made out of wasn’t “born” yet. Galaxies this far away from help astronomers understand the very early universe and how it has evolved over time. Due to the expansion of space, the distant galaxy pictured here technically wouldn’t be there anymore and would actually be “currently 13.1 Giga light-years away from us. or 4.0×109 pc.”
  2. White dwarf stars will eventually stop emitting light and become black dwarfs. There aren’t any old enough in the universe for this to have happened yet and it’s estimated that it could take about a quadrillion years.
  3. Pope John Paul II once told Stephen Hawking to not study the beginning of the universe because it was the work of God.
  4. Plasma is actually the most common phase of matter in the universe. Despite being rare on Earth. The Sun, the stars, and the most interstellar matter is plasma.
  5. In 2008, a gamma-ray burst was observed. It was a violent cosmic explosion, 7.5 billion light-years away, which is halfway across the visible universe, which could have been seen with a naked eye from the surface of the Earth. Anyone who saw it was looking billions of years into the past with their eyes.
