Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle and challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.

Galaxies grow massive through mergers with other galaxies. Massive galaxies like the Milky Way and Andromeda not only merge with other large galaxies, they also absorb their much smaller satellite dwarf galaxies. But these smaller galaxies can become quenched long before they're absorbed, and new research examines this process at Andromeda (M31).

All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly challenging. For example, there has been a debate among astronomers for decades about the path that one of our nearest neighbors, the Large Magellanic Cloud (LMC), took over the last few billion years. A new paper from Scott Lucchini and Jiwon Jesse Hand from the Harvard Center for Astrophysics grapples with that question by using a unique technique - the paths of hypervelocity stars.
