If you assume that the XDF is a typical region of outer space, you can calculate how many XDFs it would take to fill the entire night sky; itâs about 32 million. Multiply by the number of galaxies you find in the XDFâwhich is around 5,500âand thatâs how we arrive at 176 billion galaxies, at least, in the Universe.
In fact, there are estimated to be 100 billion stars in 10,000 billion galaxies in the visible universe. This means that there are roughly 1024 stars out there. These spectacular powerhouses come in an array of different colours and sizes â and many make our own Sun look like a mere pipsqueak.
