Astronomers estimate there are approx.
Our own Milky Way which is an average-sized galaxy stretches about 100,000 light years from extreme end to end. Compare that distance with the the intergalactic distance between the Milky Way and the Andromeda Galaxy some 2.2 million light years away and you get some notion of scale in the Universe. That is the closest galaxy to our own Milky Way. This scale extends into billions of light years and the Universe expands toward the wavefront of energy that cosmologists call the Big Bang. Because Windowpane Observatory is invested in the furthering of astronomical science, we make our astronomer available to you for your own questions and possible discoveries in our exciting field.
