New research reveals that collisions between stars in the galactic center are crucial in understanding mysterious phenomena.
Our planet is in the Milky Way’s suburbs—think of a quaint town in New Jersey, with the heart of Manhattan as the galactic center . However, instead of Central Park, the main attraction of the Milky Way is a supermassive black hole known as Sagittarius A*. This black hole is so large that it weighs a few million times our sun's mass.
While every star in this image has been seen to move over the past 20 years, estimates of orbital parameters are best constrained for stars that have been observed through at least one turning point of their orbit. The annual average positions for these stars are plotted as colored dots, which have increasing color saturation with time. Also plotted are the best fitting simultaneous orbital solutions.

Simulations Reveal Outcomes of Stellar Collisions at Milky Way's CenterNew research uses simulations to explore the outcomes of stellar collisions at the center of the Milky Way. Some collisions result in violent high fives, while others lead to mergers. Stars orbiting the central supermassive black hole appear young despite their ancient ages. Northwestern University researchers traced the journeys of 1,000 simulated stars orbiting Sagittarius A*.
