I wonder what is temperature in orbit where station is now?
I think -273 is in deep space, like in interstellar space.

ISS orbits within Thermosphere.

The highly diluted gas in this layer can reach 2,500 °C (4,530 °F) during the day. Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat. A normal thermometer would read significantly below 0 °C (32 °F), due to the energy lost by thermal radiation overtaking the energy acquired from the atmospheric gas by direct contact.

There is the Cosmic Microwave Background (CMB) that heats up space. It is the left over from the Big Bang (supposedly) but it is real and has been mapped by various space probes. IIRC (and I'm too lazy to look it up now) it is around 2.73K. Space doesn't get any colder than that, but humans can make things colder in artificial conditions, a few nK (may less now?) has been achieved.

Strange. North-east america, right now, is experiencing "record winter heat waves."
