And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: Genesis 1:14
"Astronomers using ESA’s Gaia satellite have discovered a large stellar stream that is currently traversing the immediate solar neighborhood at a distance of only 326 light-years. The stream contains at least 4,000 stars that have been moving together in space.
“Most star clusters in the disk of our Milky Way Galaxy disperse rapidly as they do not contain enough stars to create a deep gravitational potential well, or in other words, they do not have enough glue to keep them together,” said Dr. Stefan Meingast.
An extrapolation beyond these limits suggests the stream should have at least 4,000 stars, thereby making the structure more massive than most know clusters in the immediate solar neighborhood.
“As soon as we investigated this particular group of stars in more detail, we knew that we had found what we were looking for: a coeval, stream-like structure, stretching for hundreds of parsecs across a third of the entire sky,” said Verena Fürnkranz, a student at the University of Vienna."
