‘Gravity waves’ is an OK way to refer to gravitational radiation
There’s not lexicographical basis for complaints that ‘gravity wave’ is incorrect usage for gravitational waves.
- Physics
The long road to detecting gravity waves
Thanks to two colliding black holes, Einstein's historic prediction of gravitational waves disturbing the fabric of spacetime has finally been realized.
- Physics
Gravitational waves explained
Colliding black holes send ripples through spacetime that can be detected here on Earth. What are these gravitational waves, and how did Advanced LIGO detect them?
- Physics
Gravity waves from black holes verify Einstein’s prediction
Gravitational waves, tremors in the cosmic fabric of space and time predicted by Einstein a century ago, have finally been detected, opening a new avenue for exploring the universe.

Soviets nailed first landing on moon
The first spacecraft to safely land on the moon touched down on the lunar surface in 1966.

Odd star’s dimming not aliens’ doing
A star’s flickering light and century-long dimming have astronomers hunting for exocomet storms, prowling dust clouds and even alien engineers.
- Planetary Science
Computer simulations heat up hunt for Planet Nine
A giant planet in the far outer solar system could explain orbital oddities of bodies in the fringes of the Kuiper belt.
