Recently, the Cosmic Background Explorer or COBE satellite has carried out the most precise measurement of the temperature of the universe, specifically of the cosmic background radiation (CBR). This would be 2,726 degrees Kelvin , with a margin of error of one hundredth of a degree, according to data recorded by the spacecraft's spectrometer.
Although it is imprecise to say that the universe has a temperature, since today it is not in thermal equilibrium , explaining why the temperature of the CBR has this and no other value constitutes a challenge for astronomers.

How global warming will affect astronomy
Astronomical observations around the world will worsen in quality as a result of climate change, according to a new study.
Planetary heat wave rips through Jupiter's atmosphere
A heat wave is sweeping through Jupiter's northern hemisphere with temperatures reaching 700°C and has been created from a particularly intense aurora borealis.
These are the most Earth-like exoplanets
Among the more than 5,000 exoplanets discovered to date, these are some of the most similar in size, mass, temperature or star to the one they orbit.
Neutron stars aren't really stars.
Neutron stars are not true stars, although, thank goodness, they are made of neutrons.
Who were the first astronomers?
Since the beginning of time, human beings have observed the night sky with a mixture of fascination and fear, since it was there where the gods lived. But what was the first astronomical observation?
