Life almost certainly exists on other planets in the universe and, with only slightly less certainty, exists in our galaxy. The probability of no life elsewhere is too small to contemplate. Complex life, leading to great diversity, is much less likely.Of the thousands of exoplanets – planets around other stars – confirmed by our increasingly powerful telescopes, and despite extensive probing of the solar system, ours is still the only planet known to host life.Although no extraterrestrial life has been found and life may still be just a rarity from Earth, there are scientific reasons to suspect that it can exist elsewhere, and technological advances that may detect it if it does. Many scientists are optimistic about the chances of finding alien life.
What is NASA’s search for life : NASA's search for life
The ultimate goal of NASA's Exoplanet Program is to find unmistakable signs of current life. Exoplanets' own skies could hold such signs, waiting to be revealed by detailed analysis of the atmospheres of planets well beyond our solar system.
What planet could humans live on
Flexi Says: Right now and for the foreseeable future, humans can only live on Earth. Humans have not traveled very far into space. The Moon is the only other place humans have visited. No other planet in our solar system currently has the conditions to support life as we know it on Earth.
Can humans live on Mars : However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen.
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen.
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
Could we live on Mars
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen.Astrobiology is the study of the origin, evolution, and distribution of life in the Universe, and searching for life on Mars is a major goal of the Mars 2020 mission.Astronomers say that the planet is in the “Goldilocks zone”, meaning that the distance of the planet from its star is just right, making it not too hot and not too cold for life to exist. The same is true of the Earth in our own solar system.
Answer: From the table we see that Mercury has the greatest percentage of oxygen in its atmosphere.
Could we live on Jupiter : Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Can we live on Pluto : It's about 3.6 billion miles away from the Sun, and it has a thin atmosphere composed mostly of nitrogen, methane, and carbon monoxide. On average, Pluto's temperature is -387°F (-232°C), making it too cold to sustain life. Pluto is orbited by five known moons, the largest of which is Charon.
Does space ever end
In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
In recent years, there have been proponents and skeptics of multiverse theories within the physics community. Although some scientists have analyzed data in search of evidence for other universes, no statistically significant evidence has been found.Saturn's environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Can life exist on Jupiter : Potential for Life
While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons. Europa is one of the likeliest places to find life elsewhere in our solar system.
