The infographic at this link is worth checking out. A few observations:
- The temperatures are all in Celsius.
- Calling the Boomerang nebula the “coldest place in the universe” has always seemed a bit presumptuous to me. Still, the nebula is colder than the Cosmic Microwave Background radiation (about -270C) making the nebula colder than intergalactic voids.
- Tardigrades are a bit scary.
- Toward the bottom, the temperature increases are in orders of magnitude.
