#OTD 5 years ago, the Event Horizon 'Scope (EHT) shared the first image ever of a #BlackHole !
The black hole was M87*, and since then, the EHT also imaged Sgr A* (the black hole at the heart of our galaxy) and both objects in polarised light.
Can you say which image matches each? 1/
What is the temperature inside a black hole? It's very close to absolute zero (0 Kelvin). I wonder why that is?
