“Beautiful as it is, our Universe is constantly evolving, often through violent events like the Milky Way’s forthcoming collision with the Large Magellanic Cloud,” said Carlos Frenk, Director of the Institute for Computational Cosmology at the University of Durham. “Barring any disasters, like a major disturbance to the Solar System, our descendants, if any, are in for a treat: a spectacular display of cosmic fireworks as the newly awakened supermassive black hole at the center of our galaxy, Sagittarius A*, reacts by emitting jets of extremely bright energetic radiation.”
Editor, Jackie Faherty, astrophysicist, Senior Scientist with AMNH. Jackie was formerly a NASA Hubble Fellow at the Carnegie Institution for Science. Aside from a love of scientific research, she is a passionate educator and can often be found giving public lectures in the Hayden Planetarium. Her research team has won multiple grants from NASA, NSF, and the Heising Simons foundation to support projects focused on characterising planet-like objects. She has also co-founded the popular citizen science project entitled Backyard Worlds: Planet 9 which invites the general public to help scan the solar neighbourhood for previously missed cold worlds. A Google Scholar, Faherty has over 100 peer reviewed articles in astrophysical journals and has been an invited speaker at universities and conferences across the globe. Jackie received the 2020 Vera Rubin Early Career Prize from the American Astronomical Society, an award that recognises scientists who have made an impact in the field of dynamical astronomy and the 2021 Robert H Goddard Award for science accomplishments.
An enormous “something” more massive than a star, appears to have torn a hole in part of the Milky Way’s halo. The “dark substructure” was found in data from Gaia spacecraft observations—a mission producing the most detailed 3D map of our galaxy—with Harvard’s Ana Bonaca noticing a perturbation in a tidal stream. Bonaca is a leading authority on how the tidal field of the Milky Way galaxy disrupts globular clusters, and what the resulting debris can tell us about the underlying distribution of dark matter.

A team of researchers using the Subaru Telescope identified the outermost edge of the Milky Way –the boundary of the stellar system that makes up the galaxy. Its ultimate size is 520,000 light years in radius, 20 times larger than the 26,000 light years between the galactic center and our solar system. The galaxy is so big that it is impossible to identify the halo traces located at the outer boundary using 2.5 to four-meter telescopes.
