It's very unlikely.
No, it is not possible to live on Sedna because it is a distant and frigid dwarf planet located in the outer regions of the Solar System with extremely cold temperatures and no known atmosphere to support life as we know it.
There is currently no scientific evidence to suggest the existence of aliens on Rigel or any other star system. The search for extraterrestrial life continues to be a topic of interest for astronomers and scientists.
Scientist really cannot see enough detail on Mars to be sure. There probably is water on Mars and scientist have been studying whether there used to be life there. They are looking for living bacteria and searching for tiny fossils that might indicate life,
The life zone of a star is a region around a star where the amount of heat is enough to sustain human and plant life. Earth is in the Sun's life zone. Planets farther than that zone are too cold for life to develop there, and planets more close to the star are too hot.
Astronomers believe there is a good chance that Europa, one of Jupiter's moons, contains liquid water under its icy crust. The moon's subsurface ocean is considered one of the most promising places in the solar system to find extraterrestrial life.
Mars
no
Astronomers have found evidence that leads them to think that there is a saline ocean under the H2O ice that dominates the surface of Europa. A saline environment would be amenable to life.
no
Other than us, not yet.
No, it is not possible to live on Sedna because it is a distant and frigid dwarf planet located in the outer regions of the Solar System with extremely cold temperatures and no known atmosphere to support life as we know it.
Astronomers have not yet made any findings regarding the possibility of life on Mars.
East Africa
Earth
No, but that does not mean there aren't any. Scientists, Astronomers and Cosmonauts are trying to find evidence of alien life. They have sent signals to Space to see if there are any. For example on Uranus, Neptune Or one of Jupiter's Galilean Moons (The largest) There have been ocean or sea like things and there just might be life there.
Because there is little or none of it.
As of yet, none that is convincing, only tantalizing. The #1 question astronomers and other scientists would like to know today is: "Was there ever life on Mars?" Future robotic missions, and inevitably, men landing on Mars, may answer that question.
