Thanks for your effort but I got the answer In space, coldest temperature is recorded in Boomerang Nebula which is lesser than temperature of space itself

The coldest temperature ever recorded in the observable universe was in Helsinki University in 1999, where a record #1 xx 10^-10# K (#100# pico Kelvins) was achieved.

Explanation:

The average temperature of the universe is about #2.73#K

The coolest naturally occurring temperature that we have observed is #1#K in the Boomerang Nebula, caused by about #1,500# years of releasing gases at high speed.
