Space
We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Cosmology
Celebrating a new way to listen to the universe
Editor in Chief Eva Emerson reflects on the detection of gravitational waves as a historic moment for physics.
- Chemistry
After 75 years, plutonium is still NASA’s fuel of choice
On the 75th anniversary of the discovery of plutonium, the radioactive element is still not a major source of fuel for nuclear power plants in the United States.
- 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
‘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.
