The Boomerang Nebula — 5,000 light years away — remains the coldest known natural place in the Universe at –272°C (–458°F). But on Earth, at the Low Temperature Laboratory, Helsinki University of Technology (Espoo, Finland), scientists achieved something even colder — –273.15°C (–459.67°F), just a fraction above absolute zero. At that point, atoms almost completely stop moving. #space #science #PHYSICS #cryogenics #BoomerangNebula #finland #aaltouniversity #astronomy #cold #deepspace #astrophysi

The Boomerang Nebula is the coldest known place in the universe, with temperatures around −272°C, just one degree above absolute zero. Gas expanding rapidly cools itself, creating a cosmic freezer far colder than anything humans have ever made on Earth. Drop a ⭐ if you learned something | FactPop
