The 366 exoplanets were found by an algorithm that searched 800 million images of stars taken by NASA's Kepler Space Telescope in its K2 mission.
Scientists are now trying to learn more about the galaxy, named Pisces VII/Triangulum III, which has been described as a significant discovery.
Scientists believe the area, known as the Central Molecular Zone, could shed light on the origins of cosmic rays that bombard Earth.
The duel between the galaxies, 22 million light-years from Earth, resembles a violent encounter in the Milky Way's distant past that could have shaped it.
The possible Saturn-sized planet was detected in the galaxy Messier 51, 28 million light-years from Earth, making it the most distant exoplanet ever found.
The fact that the solar system could be traveling through a highly magnetized filament in space may also explain mysterious rope-like structures in the sky.
The massive cavity in molecular clouds within our galaxy was discovered as scientists studied the first 3D maps of these star-forming regions.
"There are likely more weird ones out there, and we need to think about how to look for them," said Davy Kirkpatrick, an author of the study.
The star cluster is located in the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way.
The vast galactic structure could tell reveal something "significant" about our own galaxy, according to one scientist.

Three astrophotographers share their top tips for taking beautiful images.
A Finnish artist who turned his camera skyward 25 years ago has completed an unprecedented image of the Milky Way.
Supernovae are cataclysmic explosions that occur during the last evolutionary stages in the life of massive stars.
Astronomers detected rare and never-before-seen structures in the galaxy's magnetic field including a helix-shaped featured and two vast "superbubbles."
The 200 stars appear to have come from a merger between the Milky Way and a dwarf galaxy long ago.
Determining the abundance of Earth-like planets is one of the major goals of planetary science.
Researchers say determining intelligence across the galaxy could give clues to our own fate.
"The flash was so powerful that it lit up the stream like a Christmas tree," said researcher Andrew Fox.
"It seems that an important part of the Milky Way's stellar mass was formed due to the interactions with Sagittarius and wouldn't exist otherwise," scientist Carme Gallart said.
The black hole forms part of a triple star system known as HR 6819, which can be seen without binoculars or telescopes from the southern hemisphere on a dark, clear night.
The fast radio burst appears to have come from a galactic magnetar and has been described as a "breakthrough" for the research field.
"Hubble has given us stunning insights about the universe, from nearby planets to the farthest galaxies we have seen so far," NASA's Thomas Zurbuchen said.
Researchers identified the minor planets beyond the orbit of Neptune.
Researchers have long debated the cause of this warping, and several hypotheses have been proposed to explain it.
"I was pretty excited. Coming into the internship, it would be hard to say that I expected to find a planet," Wolf Cukier said.
One planet, known as Proxima b, has already been detected around the star.
"It's not just a rare chance event. There has to be a mechanism to form them," study author Anna Ciurlo told "Newsweek."
