Do Interstellar Objects Pose A Threat To Earth? November 7, 2025
We're only starting to awaken to the passage of interstellar objects through our inner Solar System. So far we know of three, but there are bound to be many more. Do they pose an impact threat to Earth?
Habitable Zone Planets Around Red Dwarfs Aren't Likely To Host Exomoons November 7, 2025
The planets in our Solar System host hundreds of moons, so it seems likely that planets in other solar systems do, too. New research examines the likelihood of rocky planets around M dwarfs having exomoons, and it doesn't look good. They don't last long enough for them to give life a helping hand like Earth's […]

Astronomers Observe a Black Hole in Another Galaxy Tearing a Star Apart November 7, 2025
New study reveals, for the first time, a tidal disruption event (TDE), where a black hole tears apart a star, occurring outside the center of a galaxy that produced exceptionally strong and rapidly evolving radio signals. This rare discovery shows that supermassive black holes can exist and remain active far from galactic cores, challenging current […]
