The Universe is estimated to contain up to two trillion galaxies, each made up of billions of stars?
As far as we can tell, our own galaxy, the Milky Way, is just one small piece of an expansive cosmos that continues to astound us. Every day we learn more about the wonders of space, from cosmic explosions that light up the sky to vast clouds of interstellar dust and gases. Not to mention, there are plenty of mysteries that still baffle scientists, from the vastness of dark energy to the composition of mysterious objects like black holes and quasars. Our fascination with space only continues to grow, and with so much left to discover, it's exciting to think what else the night sky may hold.
