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.

∙ 15y agoA big (non-scientific) law in the universe is the "Law of Mediocrity". It states that we shouldn't figure we're the best/only/unique/top of the heap/special because if we can do it it can be done by others too, and probably better.
When astronomers look into the unierse they see uncounted billions of stars, with a percentage of them being G-types like our own sun. hey estimatethat at leat 10% of these stars have planetary systems like ours. Fro this still immense number it is likely that life is present on some or all of them.
Astronomers look at data from analysis of the chemistry of the universe and find the basic building blocks of life everywhere. If life could arise here from these materials it is likely that it could arise in other places.
Astronomers and their friends the organic chemists know that the basic building blocks of life an be turned into the more complex building blocks of life by the action of UV light, electricity, heat and cold. It happened here and it can happen anywhere in the Universe
Astronomers and their friends the biologists look at life on Earth and find it everywhere from the depths of the oceans in the acid, boiling hot, poisonous waters from "black smokers", to water seeping in the pores of boiling hot rocks kilometers below ground, to the edge of space. If life could survive under these extreme conditions it can likely get a toe-hold anywhere - and there are a lot of anywheres in the universe.

Why do scientist hypothesize that Mars may once have had the conditions needed for life to exist?
life to exist there
Will Astronomers find evidence of life on Sedna?
It's very unlikely.
What layer of the atmosphere does life exist?
The troposphere is the only layer where life can exist
Are there any possible places besides earth where life can exist?
Without question, in the minds of most planetary scientists, yes.
Will you turn into a mermaid on a full moon if you are in water?
No. People can not change into other things. There is no magic to change people and not mermaids/mermen. They do NOT exist in real life. You can not become one.
What planet do astronomers believe there is life?
Earth
Why do people believe in a supreme being but not in the supernatural or life elsewhere in the rest of the universe?
Belief in a supreme being is actually a belief in the supernatural, but most people who believe in a supreme being are taught or conditioned as to what it is permissible to believe. Sometimes that conditioning extends to not accepting the possibility that life could exist elsewhere in the universe. More important to the issue of belief in the possibility of intelligent life elsewhere in the universe is that this could call into question the entire basis of religions as we know them.
Is there life anywhere else in the whole universe?
Currently it is not known. With current technology, we are not able to detect the presence of life on other planets even if it does exist. However, we now know that planets are relatively commonplace, which many scientists believe strongly suggests that life must exist elsewhere in the universe.
Besides Earth astronomers believe they are most likely to find evidence of life on what planet?
Mars
Is the Elixir of life real?
for those who believe,.. the elixir exist
Do astronomers think there could be life on europa?
They believe there is liquid water underneath its frozen surface. If there is liquid water on Europa, there might also be life.
What different types of scienist are there for Astronomy?
Most astronomers specialize in physics, but there are also those who specialize in geology who study planets, and those specializing in biology, who speculate on life elsewhere in the universe.
What objects live in space?
"Objects" generally doesn't refer to living things, but the only life in the universe that is currently known to exist is contained on Earth. (However, certain precursors of cellular life are likely to exist elsewhere, if not full life-forms)
When was Life Is Elsewhere created?
Life Is Elsewhere was created in 1973.
How did the idea come up?
It came about from people wondering if there was life elsewhere in the Universe, many people believe that there are life forms on other planets and others do not.
Do astronomers thinks there could be on europa?
They believe there is liquid water underneath its frozen surface. If there is liquid water on Europa, there might also be life.
Can life exists on other planet then earth?
So far as is known to date there is no life on any other planet in our solar system or elsewhere. That does not rule out the possibility that life may exist on other planets
