The Drake formula (calculating the probability of discovering intelligent aliens): the missing parameter and the fate of humanity

The Drake formula was an attempt to calculate the probability of intelligent life on other planets. But human history shows that the formula was probably too optimistic, and that there is something missing in the calculation. This missing parameter can

Processing of one of the images taken with the Hubble Space Telescope in ultraviolet radiation. Note the light blue structures that protrude from the surface of Europa's moon into space (at the bottom of the moon on the left side, 7 o'clock). Further tests revealed that these were most likely water eruptions from the surface of the moon.

Simulation of the orbital configuration of the Wolf 1061 system. Wolf 1061 is an inactive red dwarf, small and cold from the Sun located 14 light years away from us. The orbits of planets b, c and d have a duration of 4.9, 17.9 and 67.2 days. In the simulation it is seen that the orbits of the planets are on one plane. The habitable zone around the star is marked in green - the part where it is too hot is marked in red and the cold part in blue.
