Nasa has revealed that there are far fewer galaxies in the universe than previously thought.

The Milky Way may be one of only billions of galaxies in the universe, rather than trillions as previously estimated.

To estimate just how many galaxies are really out there, the team analysed existing images from New Horizons.

Thankfully, the remaining signal was just about measurable, allowing for a more accurate estimate of the number of galaxies.

However, Hubble relied on mathematical models to estimate the number of galaxies, as many galaxies were believed to be beyond the space telescope's ability to detect in visible light.

Monster galaxies, also known as starburst galaxies, are thought to be ancestors of massive galaxies like the Milky Way in today's universe
