In a first, astronomers spot the aftermath of an exoplanet smashup
Infrared light from a distant star appears to be leftovers of an impact between a pair of Neptune-sized worlds.

Scientists Say: Pulsar
These rapidly spinning dead stars send beams of radio waves into space like cosmic lighthouses.
- Physics
Scientists Say: Explosion
Explosions happen when chemical or nuclear reactions blow out a lot of heat, noise and expanding gas.

Jets may have sculpted rings of Cat’s Eye nebula
The Cat’s Eye nebula is one of the most complex of its kind. A 3-D model now reveals the source of that complexity.

Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.

A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.

Explainer: Calculating a star’s age
Scientists can figure out a star's mass or composition pretty easily. Determining how old that star is, however, is a lot harder.
