An international of researchers, including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) have used the James Webb Space Telescope to uncover 12 black holes from 12.9 billion years ago, shedding light on how black holes and galaxies evolved in the early Universe.

Jupiter and its moons are busy in October. If skies are clear, be sure to set your alarm and follow the largest planet in our solar system this month. While massive Jupiter always warrants a view through even a small telescope, its four major Galilean moons warrant special interest, as we’re in the midst of a season of rare double shadow transits.

It's Harvest Moon week, when the Moon shines low and bright at nightfall for many days running. Along the way it passes edge-on Saturn.
