Galaxy Zoo Team Discovers New Class of Galaxy Cluster

[/caption] A new class of galaxy clusters has been identified by volunteers and astronomers of the Galaxy Zoo project, together with the Sloan Digital Sky Survey. These clusters are rare, and have apparently gone unnoticed before, despite their unusual linear properties. Astronomers believe the identification of these types of clusters depend on the visual inspection of large numbers of galaxies, a feat which has only recently been made possible by the Galaxy Zoo project, and this may explain why they haven't been discovered until now. "Space is, after all, really big," said the Galaxy Zoo scientists, "and full of really surprising things."

These clusters are unusually elongated, possess young and highly dynamic galaxy populations, and most unexpectedly, present neatly typeset, left-justified, messages written in the English language. One sample even includes punctuation similar to an exclamation mark. (See image below.)

[/caption] The occurrence of these new galaxy phenomena could potentially lend support to some of the more exotic models for Dark Energy or modified gravity, which one of the Universe Today trolls may find extremely notable. More controversially, as most occurrences of English sentences are considered to be the work of intelligent beings, the existence of these messages might indicate intelligent life beyond our own.

Conversely, however, they could indicate that many phenomena usually attributed to intelligent life on Earth may actually occur spontaneously, without any thought necessarily being involved at all. While these new discoveries may have profound implications for cosmology, the most important thing to consider is the date of this publication, being April 1.

The Galaxy Zoo team stresses that, despite their implausible appearance, the galaxies comprising each individual character in the figures presented here are taken directly from the SDSS multicolour composite imaging. Note, however, that some degree of translation and rotation has been performed to the individual characters, for presentation purposes.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
