Why does the inside of the solar system not spin faster
The motion of a tiny number of charged particles may solve a longstanding mystery about thin gas disks rotating around young stars, according to...
Scientists shed new light on dark matter
Scientists have developed a method for predicting the composition of dark matter—invisible matter detected only by its gravitational pull on ordinary matter and whose...
Cosmic radio pulses could help explore hidden matter around galaxies
Powerful radio pulses originating deep in the cosmos can be used to study hidden pools of gas cocooning nearby galaxies, according to a new...

Liquid water could exist for billions of years on non-Earth-like planets
Low-mass planets with a primordial atmosphere of hydrogen and helium might have the temperatures and pressures that allow water in the liquid phase.
The...
This star not only survived a supernova, but also became brighter
A supernova is the catastrophic explosion of a star.
Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind.
At...
