Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
Magnetars are some of the most extreme objects we know about, with magnetic fields so strong that chemistry becomes impossible in their vicinity. They’re neutron stars with a superfluid interior that includes charged particles, so it’s easy to understand how a magnetic dynamo is maintained to support that magnetic field. But...
Astronomers have uncovered a link between Neptune’s shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun’s entangled magnetic fields drives solar activity.
A new NASA study offers an explanation of how quakes could be the source of the mysteriously smooth terrain on moons circling Jupiter and Saturn.
I love the show One Strange Rock, I know Will Smith has pretty much lost his noodle, but c’mon, couldn’t there be a different host and still listen to the astronauts? Has @astropettit made it here yet? Are there any other shows that offer a look from the astronauts point of view?
We noticed this community was abandoned by its previous founder and moderators, and so we’re here to help it thrive again!...

New observations of a faraway rocky world that might have its own magnetic field could help astronomers understand the seemingly haphazard magnetic fields swaddling our solar system’s planets.
This was a really well written article describing what we know about Neptune.

Been Studying alternatives to Dark Matter and the rabbit hole has led me to MOG/STVG by John Moffat. The video I’m sharing is a long and great interview by Curt Jaimungal with Moffat. There are plenty of MOND-like alternatives to Dark Matter and all may be proven wrong should science make further progress discovering Dark...
Voyager Space, one of several US companies formulating concepts for new commercial space stations, has established a joint venture with Airbus to co-develop an Earth-orbiting research outpost called Starlab....
What are the risks, by the numbers? How many asteroids hit Earth and how many can we expect to zip past us?
