Arecibo Observatory, an ‘icon of Puerto Rican science,’ will be demolished
The telescope, known for cameos in moves like Contact and for fast radio burst observations, was feared to be on the verge of collapse.
- Space
Planets with many neighbors may be the best places to look for life
Solar systems with many planets in circular orbits suggest a calm life-nurturing past, while single exoplanets with eccentric orbits hint at chaos.
