It is likely to evolve into an elliptical galaxy, instead of a spiral
Astronomers Discover First Look-alike galaxy 12 billion light-years away. Astronomers at the Planck Institute for Astrophysics have found a look-alike of the Milky Way 12 billion light-years away. The help of the Atacama Large Millimetre/sub-millimetre Array (ALMA).
- “The galaxy is thus far away its light has taken quite 12 billion years to succeed in us,” the institute said in a politician handout .
This makes it a good more engaging discovery as consistent with the National Aeronautics and Space Administration (NASA) our universe is around 13 billion years, give or take a couple of billion.
- “This result represents a break through within the field of galaxy formation, showing that the structures that we observe in nearby spiral galaxies and in our Milky Way were already in situ 12 billion years ago,” says Francesca Rizzo. PhD student from the Planck Institute for Astrophysics in Germany, who led the research published within the journal Nature.
The galaxy, called SPT0418-47, doesn’t appear to possess spiral arms lie. Our Milky Way but Has a minimum of two features that are almost like our galaxy: a circular disc and a nodule. This is the primary time a lump has been seen this early within the history of the Universe, making SPT0418-47 the foremost far-off Milky Way look-alike, analyst said.
The big surprise
- “The big surprise was to seek out that this galaxy is really quite almost like nearby galaxies, contrary to all or any expectations from the models and former , less detailed, observations,” said co-author Filippo Fraternali, from the Kapteyn Astronomical Institute, University of Groningen within the Netherlands.

It is difficult for researchers to watch these galaxies even with the foremost powerful telescopes thanks to the space . The team utilized a close-by galaxy as a strong hand glass — an impact referred to as gravitational capture to beat this hard. This allowed ALMA “to see into the distant past in new detail. during this effect, the gravitational pull from the nearby galaxy distorts and bends the glow from the distant galaxy, causing it to seem twisted and multiply.”
- “What we found was quite hard; despite forming stars at a high rate, and thus being the location of highly energetic processes. SPT0418-47 is that the most well-ordered galaxy disc ever observed within the early Universe,” said co-author Simona Vegetti, also from the Planck Institute for Astrophysics.
- “This result’s fully unexpected and has important meaning for a way we expect galaxies evolve.”
Though the galaxy is sort of almost like ours, astronomers expect it to evolve into a galaxy very different from the Milky Way. it’s likely to get into an elliptical galaxy, instead of a circular.
