"Biosignatures in the form of screaming" suggests that any life that had developed on the planet would be in continuous pain or fear due to their hazardous surroundings. In addition, this suggests that the screaming of these organisms would cause ripples in the atmosphere which we should be able to detect light-years away through the vacuum of space and that it would be more noticeable than other signs of life (such as the spectra from the ash produced by burning organic material.) | "Biosignatures in the form of screaming" suggests that any life that had developed on the planet would be in continuous pain or fear due to their hazardous surroundings.

− | The title text mentions that fire could indicate the presence of life. | + | The title text mentions that fire could indicate the presence of life. Sustaining a fire over time requires a sufficient supply of oxidiser. A steady supply of oxygen as oxidiser could be provided by plant life, which is the case on Earth. However, the plants known on earth could not survive on a flaming planet. It is worth noting that the title text mentions fire only as a potential biosignature since oxidisers other than oxygen exist and plants aren't its only possible source. It also mentions that such a fire would help indicate that the planet '''had''' supported life, '''before''' the gas released by the native life forms was ignited. |
