Black hole smashup generated yottawatts of power
For a split second, LIGO’s black hole collision generated 36 septillion yottawatts of power, or 50 times the power from all the stars in the universe.
- Planetary Science
Mountains on Pluto are a winter wonderland of methane snow
On Pluto, methane snow blankets mountain tops.
- Planetary Science
Mercury’s dark secret revealed
Graphite from Mercury’s primordial crust might be responsible for making the innermost planet darker than the moon.
- Astronomy
A fast radio burst’s home galaxy may not be known after all
The recently claimed host galaxy of a fast radio burst may have been signs of a snacking black hole instead, study claims.
- Astronomy
Repeating fast radio bursts recorded for the first time
Until now, ephemeral blasts of radio waves from other galaxies have never repeated; this one erupted 10 times last year.
- Astronomy
Astronauts set to return to Earth after nearly a year in space
Scott Kelly and Mikhail Kornienko are scheduled to return Earth on Tuesday after a record-setting 340 days in space.
- Planetary Science
Charon’s surface cracked when ancient subsurface sea froze
A subsurface ocean on Charon, Pluto’s largest moon, might have once frozen and cracked the moon’s surface, creating some of the ridges and valleys seen today.
- Astronomy
Fast radio burst tracked to its galaxy of origin
After years of searching, astronomers finally track an elusive cosmic radio signal to its home: a galaxy about 6 billion light-years away.
- Astronomy
Black hole heavyweights triggered gravity wave event
Those gravity waves came from two black holes more massive than any known outside a galactic core and formed in an environment different than the Milky Way.
- Planetary Science
120 seconds in Pluto’s shadow
A 747 outfitted with a telescope worked with New Horizons to reveal details about Pluto’s atmosphere.
- Astronomy
Planets may emerge from stellar duo gathering icy dust
Gas freezing onto dust grains around a binary star could be setting up a site where comets or even planets might someday form.
- 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?
