Some cool facts about the Universe?

    • The very furthest galaxies are spreading away from us at more than 90% of the speed of light.
    • A day on Mercury lasts approximately as long as 59 days on earth.
    • The Milky Way galaxy is whirling rapidly, spinning our sun and all its other stars at around 1 million km per hour.
    • The Milky Way galaxy we live in: is one among the BILLIONS in space.
    • There may be 20 trillion galaxies in the Universe.
    • The brightest star in each constellation is called the Alpha Star, the next brightest Beta, and so on.
    • The red color of Mars is due to oxidized (rusted) iron in its soil.
    • Jupiter has no surface for a spacecraft to land on because it is made mostly from helium gas and hydrogen. The massive pull of Jupiter’s gravity squeezes the hydrogen so hard that it is liquid.
    • The largest moon in the Solar System is the Jupiter’s moon Ganymede

    Wow, these are some mind-blowing facts about the Universe! It's amazing to think about how the furthest galaxies are moving away from us at such incredible speeds. And the fact that there may be 20 trillion galaxies out there is mind-boggling. I never knew that Jupiter doesn't have a solid surface and that its gravity squeezes hydrogen into a liquid state. And Ganymede being the largest moon in the Solar System is just mind-blowing. Thanks for sharing these cool facts, noori!

    Wow, those are some mind-blowing facts about the Universe! It's absolutely fascinating to learn about the speed at which the furthest galaxies are moving away from us, reaching speeds of over 90% of the speed of light. Additionally, the sheer number of galaxies out there, potentially 20 trillion, is truly mind-boggling.

    I was also amazed to discover that Jupiter, the largest planet in our Solar System, lacks a solid surface and is predominantly composed of helium gas and hydrogen. The incredible gravitational force of Jupiter compresses the hydrogen to such an extent that it becomes a liquid. Furthermore, the fact that Ganymede, one of Jupiter's moons, holds the title of the largest moon in the Solar System is awe-inspiring. These cool facts truly highlight the immense wonders and mysteries that lie within our Universe.
