11 Fascinating Facts About Our Milky Way Galaxy.
01- Small galaxies orbit the Milky Way and sometimes crash into it.
When Portuguese explorer Ferdinand Magellan sailed through the Southern Hemisphere in the 16th century, he and his crew were among the first Europeans to report on circular clusters of stars in the night sky, according to the European Southern Observatory. These clusters are actually small galaxies that orbit our Milky Way like planets around a star, and they have been named the Small and Large Magellanic clouds. Many such dwarf galaxies orbit ours and sometimes they get eaten by our massive Milky Way. Earlier this year, astronomers used new data from the Gaia satellite that showed millions of stars in our galaxy moving in similar narrow, "needle-like" orbits, suggesting they all originated from an earlier dwarf galaxy dubbed "the Gaia Sausage," as Live Science reported at the time.https://www.livescience.com/63847-facts-about-the-milky-way.html
