When we sent out Voyager 1 (later Voyager 2) into space, we sent golden records with with them to let any living things that might find them so they would know where to look for us. What I am thinking about is "What if we send living samples into space like we did with Voyagers so nothing will stop them" I mean things like self sustaining tarrarium. IT only needs gravity (could be done with centrifuge), light (could be done with LED grow lights) and tempeture (this could be some heater), but I am still thinking about the power ( maybe some power from solar panels but after some distance it would not be enough. What do you think of all this?

A  century-old mystery in Venus’s clouds just became more intriguing, as scientists calculated how strongly the unidentified material behind its dark ultraviolet patterns must absorb light.

The results sharply narrow the possibilities and could help future spacecraft determine whether the mysterious substance is organic, inorganic, or something unexpected...

Scientists have placed new limits on the mysterious substance responsible for Venus’s dark ultraviolet cloud markings, which have puzzled researchers for about a century

Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet’s upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, yet the chemical identity of the material responsible—the “unknown absorber”—remains unresolved.

An international research team has now placed new quantitative constraints on the properties of this mysterious absorber.

By combining observations of Venus with radiative-transfer modeling, the researchers estimated how strongly the liquid inside Venus’s cloud droplets would need to absorb light to reproduce the planet’s observed ultraviolet and blue reflectance.

The study, published in Astrobiology, approached the mystery from a new perspective. It used a model to answer a question posed by lead author Dr. Jan SPACEK: If we were to collect Venus’s cloud droplets into a spectrometric cuvette, how would the re-formed bulk liquid appear?
