Astronomers Have Found 72 New Galaxies And Trillions Of New Alien Planets

Another stunning discovery has just been made as researchers taking part in the deepest spectroscopic survey ever conducted have found 72 never-before-seen galaxies.

Furthermore, as noted by experts, these new galaxies have the potential to host trillions of alien planets, and some could be favorable for human life, while others could harbor alien life.

Located within the so-called Hubble Ultra Deep Field (HUDF), the 72 new galaxies come as exciting news, and are proof of the development made in recent years towards understanding our planet in the universe, and whether or not we are alone in it.

The Hubble Ultra Deep Field has been the target of various observations in the past, however, the new galaxies weren’t visible until astronomers actually looked at the patch of sky using the MUSE—ESO’s Multi Unit Spectroscopic Explorer.

Experts note that these galaxies remained hidden because they are Lyman-alpha emitters which basically means they only shine brightly in one color.

Furthermore, unlike observations produced with other telescopes, the Multi Unit Spectroscopic Explorer, as its name states, uses spectroscopy in order to break light into its component colors.

Roland Bacon of Lyon Centre for Astrophysics Research (CRAL), who led the MUSE HUDF Survey team, said in a news release:

“This allows us to measure the distance, colors, and other properties of all the galaxies we can see — including some that are invisible to Hubble itself.”

The new survey not only discovered 72 new galaxies, with trillions of potentially new alien worlds, but it also led to the collection of detailed spectroscopic measurements for 1,600 total galaxies, notes Futurism, explaining that using different ground-based telescopes in the past, astronomers could only obtain such precise measurements for about one-tenth that many galaxies.

The new discovery made by MUSE has yielded 10 new scientific papers all of which are due to be published in a special issue of Astronomy & Astrophysics. The studies range from how stars formed in the early universe, to ho material flow in and out of different galaxies.

The discovery is extremely important as it shows us just how many galaxies and planets exist in the universe with chances of hosting alien life.

NASA believes that in our galaxy alone there are between 100 and 400 billion stars. If all other stars have around 8 planets orbiting them, it would mean that the milky way could be home to up to 3.2 trillion planets.

If we take a look at the new, 71 recently discovered galaxies have at least 100 billion stars, and also 8 planets per star, we could be looking for aliens in 57.6 trillion worlds.

How’s that for ‘We are alone in the universe’ sound?
