Is there life outside of Earth?
People often think of other planets in our solar system like
Jupiter, Mars and Neptune when trying to answer this
but that is thinking too small and close.
The sun is a star. Just like the sun, other stars have planets
around them. Our galaxy (Milky Way Galaxy) is estimated to have between 100 to
400 Billion stars.
The probability that there is a planet out there with life in the
more than 100 billion solar systems just in our galaxy is high.
All that is just in one galaxy. scientists estimate there's between
100 billion to 2 trillion other galaxies in the observable universe.
