We summarize the week's scientific breakthroughs every Thursday.
- Planetary Science
Solar system’s future could be bumpy
A new study assesses the chances that two planets will collide or a planet will plunge into the sun in the next 5 billion years.
- Astronomy
Pinning down a pulsar’s age
Reporting at a meeting of the American Astronomical Society, researchers suggest some of these swirling stellar remnants are older, younger by a factor of 10.
