At the heart of the Milky Way, stars draw closer, threatening planets in their orbit
At the center of our galaxy resides the galactic bulge, a densely packed region of stars, dust and gas. Within this massive structure, which spans thousands of light-years, there are an estimated 10 billion stars, most of which are old red giant stars. Because of this density, astronomers have often wondered if a galactic bulge is a likely place to find stars with habitable planets orbiting them.
