We summarize the week's science breakthroughs every Thursday.
- Planetary Science
The moon is about as old as we thought it was
Meteorite heat signatures pinpoint the age of the collision that created the moon — confirming many previous lunar age estimates.
- Astronomy
Ringing rings reveal Saturn’s innards
Scientists propose that exotic structures are buried within Saturn, based on analyses of subtle vibrations in the planet’s rings.

Galactic split provides clue to dark matter mystery
An oddly divided galaxy may provide the first evidence that dark matter particles interact through a force other than gravity.

Map pinpoints location of invisible dark matter
A new map shows that dark matter is concentrated in regions that contain a lot of ordinary matter in the form of galaxy clusters.

Map pinpoints location of invisible dark matter
Dark matter can’t be seen, but a new map shows where it’s hiding. The map confirms that the mysterious matter is concentrated in regions that contain a lot of ordinary matter in the form of galaxy clusters.
- Planetary Science
Atmospheric water may be giving Saturn its spots
Planetary scientists think that water in Saturn’s atmosphere could be driving the massive storms that appear every few decades in the ringed planet’s atmosphere.

Comet 67P shows no sign of magnetism
Philae found no evidence of a magnetic field on comet 67P/Churyumov-Gerasimenko, but did send back some clues about its rough landing.
- Astronomy
Afterglow alerts astronomers to gamma-ray burst
Astronomers have spotted the remnant glow from a gamma-ray burst without first observing its beam of high-energy gamma rays.
- Astronomy
Source of puzzling cosmic signals found — in the kitchen
One type of radio burst has a pretty mundane origin: prematurely opened microwave ovens.
- Planetary Science
A modest Plutonian proposal
Flagstaff, Echidna, Spock. Naming conventions for the landscapes of Pluto and its moons are proposed ahead of the arrival of the New Horizons probe.

Cyanides around young star signal complex organic chemistry
Abundances of cyanide compounds around a young star match those found in comets in our solar system.

One anniversary to celebrate, one to contemplate
In this issue, both feature articles focus on anniversaries, though of two very different kinds.
