Faint gravitational waves could soon be on LIGO’s radar
In a few years, LIGO could detect hints of faint gravitational waves from black holes too far away to be seen directly.
- Astronomy
Odd white dwarf found with mostly oxygen atmosphere
A white dwarf that has been stripped of its hydrogen and helium provides a rare peek inside the core of a dead massive star.
- Astronomy
This eclipse goes on and on
The longest known stellar eclipse hides a nearby star for nearly 3.5 years behind a thick clump of orbiting dust once every 69 years.
- Astronomy
Earth’s hurricanes have nothing on this quasar
In a remote galaxy, a cosmic hurricane around a supermassive black hole is driving winds at nearly 20 percent of the speed of light.
