A new study using the Vista telescope has shown that the Large Magellanic Cloud is distorting its companion, the Small Magellanic Cloud. This dwarf galaxy, located 200,000 light-years from Earth, is affected by the gravitational pull of the Large Magellanic Cloud, causing its stars to move away from the center.
- 01The Large Magellanic Cloud is approximately 163,000 light-years away from Earth.
- 02The Small Magellanic Cloud, a dwarf galaxy, is located about 200,000 light-years from Earth.
- 03The study utilized the Vista telescope over eleven years to observe the Small Magellanic Cloud.
- 04Stars in the center of the Small Magellanic Cloud are moving away at a speed of 10.6 miles (17 kilometers) per second.
- 05The findings suggest that the Small Magellanic Cloud had a more compact structure in the past.

Recent research has unveiled the influence of the Large Magellanic Cloud on its companion, the Small Magellanic Cloud, located about 200,000 light-years from Earth. Using the Vista telescope in Chile, astronomers conducted observations over an eleven-year period, allowing them to penetrate interstellar dust and examine the motion of stars within the Small Magellanic Cloud. The results indicate that the gravitational pull from the Large Magellanic Cloud is causing stars at the center of the Small Magellanic Cloud to move away at a speed of 10.6 miles (17 kilometers) per second. Florian Niederhofer, a researcher involved in the study, expressed astonishment at the quality of the stellar motion measurements, which provided an unprecedented level of detail regarding the internal kinematics of the Small Magellanic Cloud. This research not only highlights the current dynamics of the Small Magellanic Cloud but also suggests that its structure was significantly more compact in the past, indicating a transformation influenced by the gravitational forces at play.
