One early result of the 2nd release of the still ongoing Dark Energy Survey is the previously untold story revealed by old, giant RR Lyrae (RRL) pulsating stars with a mass of around half the sun’s, which tell scientists about the region of space beyond the edge of our Milky Way. These large-amplitude stars serve as tracers and distance indicators of old stellar populations in the Milky Way and neighboring galaxies. They are also essential laboratories for testing evolutionary and pulsation models.
A string of 13 dwarf galaxies in orbit around the massive galaxy Andromeda –remnants of the population of primordial structures that coalesced to form giant galaxies like the Milky Way–are spread across a flat plane more than one million light years wide and only 30,000 light years thick –a distance so vast that they have yet to complete a single orbit. The 2016 discovery suggests that conventional ideas regarding the formation of galaxies are missing something fundamental.
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.
The frustrating quest for dark-matter continues. An unidentified X-ray signature recently observed in a nearby galaxy clusters is not due to the decay of dark matter, researchers report. The findings ruled out previously proposed interpretations of dark matter particle physics. But the near future for solving this great mystery of 21st-century astronomy looks bright.
