I’m off to see Mom

I’m leaving on a jet plane, don’t know when I’ll be back again … stay tuned.

XRISM Provides the Sharpest Image to Date of a Rapidly Spinning Black Hole January 5, 2026
The first results on the iconic active galactic nucleus MCG–6-30-15 captured with the XRISM mission show the most precise signatures yet of its supermassive black hole’s extreme gravity and the outflows that shape its galaxy.
New Research Reveals how Gravitational Waves Could be Used to Decode Dark Matter January 3, 2026
A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on Einstein’s theory of general relativity, that tracks in detail how a black hole interacts with […]
Earth-like Planets Need a Cosmic-Ray Bath January 3, 2026
Terrestrial planets such as Earth need an early solar system rich in short-lived radioisotopes. But the supernovae that create these elements would tend to rip an early system apart. A new study suggests that these isotopes are produced by a bath of cosmic rays from more distant supernovae.
Using Webb, Canadian Astronomers Shed Light on the Milky Way's Turbulent Past January 2, 2026
A team of Canadian astronomers has used Webb's observations of "Milky Way twins" in the early Universe to learn more about our galaxy's turbulent youth.
Solar Flares and Stellar Flares Hit Different January 2, 2026
Sunspots and solar flares go hand in hand. They generally occur in the same region of the Sun around the same time. We've long thought the same would be true for other stars, but a new study finds that isn't the case.
