Is the earth a test planet for extraterrestrials

1 phenomenon could point to extraterrestrial life for a long time

Humanity has been searching for the decisive one for ages Notethat in the universe extraterrestrial life exists. Researchers have now developed a completely new methodology that should help to finally track down hidden life in space.

Extraterrestrial Life: These signs in the universe could be indicative

According to researchers, the flickering of ultraviolet radiation from red suns can help to find hidden alien habitats. This radiation in the universe could trigger a protective glow emanating from life forms on exoplanets, the so-called autofluorescence or biofluorescence.

Cornell University's study includes an entirely new approach to tracking extraterrestrial life in the universe, according to lead author Jack O'Malley-James: "Imagine an extraterrestrial world that glows softly when viewed through a powerful telescope. "

Already on earth there are life forms that use biofluorescence to translate harmful UV radiation from the sun into harmless, visible wavelengths. Assuming that such extraterrestrial life also exists, there would also be a clear sign in the universe that betrays its existence.

Luminous exoplanets visible through telescopes

Astronomers generally agree that a large proportion of exoplanets, i.e. those planets outside of our solar system, are in a habitable zone of M stars, red suns. These are in abundance in the universe.

They flicker regularly and as a reaction could cause biofluorescent glow of extraterrestrial life on the neighboring planets. Such enlightened worlds could then be found through the next generation of earth- or space-based telescopes.

Testplanet is supposed to help find extraterrestrial life

To create model spectra and colors for such planets in the universe, astronomers use the emission characteristics of fluorescent pigments from corals. This is to determine the strength of the signal and whether it can be held for life.

The aim of such a test is to serve the exoplanet Proxima b-a, a world potentially habitable by extraterrestrial life that orbits the M-star Proxima Centarui. According to O'Malley-James, luminescence is considered to be one of the best chances of finding extraterrestrial life on exoplanets.

However, the actual series of tests can only be carried out with the coming generations of telescopes that can collect enough light from small planets for analysis. After all, the first possible signs of extraterrestrial life were already discovered on Mars, albeit differently than the Cornell researchers have in mind.
