Terraforming Tidally-Locked Worlds
- Terraforming a tidally locked planet faces challenges due to eternal daylight on one side and eternal darkness on the other.
- The daylight side could become a humid jungle, while the dark side remains frozen and uninhabitable.
Reusable Rockets Reduce Ocean Impact
- The rocket industry is moving toward reusable technology to reduce ocean debris.
- Current ocean rocket debris is minimal compared to other pollutants, but ignoring it risks future pollution problems.
Sagittarius A* Image Is Real Data
- Images of Sagittarius A* from the Event Horizon Telescope are based on real radio wave data from a global telescope network.
- The image shows the black hole's shadow with features verified by actual data, though colorized for human visualization.
