” One, Leo T, still has gas associated with it, providing the raw material for stellar births. “It’s arguably the smallest star-forming galaxy known,” Zucker says. The survey that found the satellite galaxies scanned only a fifth of the sky, so there could be dozens more waiting to be found.
In another surprise, Harvard University astrophysicist Nitya Kallivayalil recently announced that two of our largest satellite galaxies probably aren’t satellites at all. Kallivayalil found that the Large and Small Magellanic clouds are shooting by us at around 200 miles per second, faster than a satellite would. Louis J Sheehan
