Dust erases evidence for gravity wave detection
The claimed detection of primordial gravitational waves does not hold up after taking into account galactic dust, a new analysis concludes.
- Astronomy
Neptune-like worlds could become habitable
Mini-Neptunes can drift toward their stars and lose their atmospheres, leaving behind ice-rich rocky cores that can become watery worlds.
