- 			 Science & Society Science & SocietyScience puzzles no longer so puzzlingThis year, researchers solved the riddle of mysterious radio bursts, the Erdös discrepancy problem and an elusive acid. 
- 			 Astronomy AstronomyEquipment failure pushes back Mars lander missionThe launch of the Mars InSight lander is suspended until at least 2018 because of a faulty seismometer. By Andrew Grant
- 			 Planetary Science Planetary ScienceEquipment failure delays Mars missionA leaky instrument will push back launch of the Mars InSight lander by at least two years. By Andrew Grant
- 			 Astronomy AstronomyNew recipe found for making supermassive black holeThe universe’s first supermassive black holes may have formed directly from gas in colliding galaxies, new simulations suggest. By Andrew Grant
- 			 Tech TechSpaceX rocket blasts to space and back, sticks the landingA Falcon 9 rocket section lands after launching a set of satellites during a successful test of SpaceX’s reusable rocket parts.

- 			 Astronomy AstronomyExoplanets need right stuff to be habitableThe elemental makeup of a star can reveal whether planets in its solar system could support sustained plate tectonics, a requirement for Earth-like life, researchers propose. 
- 			 Physics PhysicsPulsar pair ripples spacetimeA pair of pulsars gives scientists the best evidence so far for gravitational waves, which have yet to be detected directly. By Andrew Grant
- 			 Physics PhysicsGeneral relativity caught in action around black holeX-rays enable scientists to spot a black hole twisting the surrounding fabric of spacetime, just as Einstein’s theory predicts. By Andrew Grant
- 			 Cosmology CosmologyDebate grows over whether X-rays are a sign of dark matterThe dwarf galaxy Draco, which is chock-full of dark matter, doesn’t emit a band of X-rays that researchers hoped were produced by the mysterious invisible stuff. By Andrew Grant
- 			 Planetary Science Planetary ScienceIt’s a new planet! It’s an unknown star! It’s — oops!A couple of unexpected wandering points of light in the sky could be new planets or even a dim star orbiting the sun, but researchers have plenty of reasons to be skeptical. 
- 			 Astronomy AstronomyLISA Pathfinder to pave way for gravitational wave detectionThe successful launch of the LISA Pathfinder mission marks the first step toward testing techniques needed to build a space-based gravitational-wave detector.
