What A Planet Needs to Sustain Life
What
Temperatures. To be like earth, needs to be warm enough for water to be liquid.
Venus
too hot because the atmosphere is too thick & warm
Mars
Too thin and cold atmosphere which makes it too cold to be liike Earth
Earth
Earth has perfect atmosphere because its not too cold or too warm
Magnetic fields. Earth has magnetic fields to protect its inhabitants from the sun's radiation.
Venus
Has no protection for deflecting solar particles
Mars
Mars is unprotected because it has no magnetic field
Earth
Has a magnetic field that allows energy to o through and reach Earth's atmosphere
How & Why It's Important
Magnetic Fields
scientists say that magnetic fields help planets interact with energy of the sun & wind than with itself alone
Habitable?
Doing further research & gathering knowledge will help us understand if planets likes Venus & Mars were ever inhabitable & if they can be
Estimation of 40 - 100 billion of planets are inhabitable within our galaxy
Atmospheres
research will allow us to gain knowledge about different atmospheres
Who
Scientists are working towards knowing how many molecules move out of the magnetic field and if it influences it in any way
Strong belief that over a period of time, humans will come to know of other planets that are habitable
Where
To figure out if life on other planets is possible, actions have been taken
Spacecrafts have been sent to both planets (Mars & Venus)
MAVENS spacecraft currently orbiting Mars
When all information is gathered, it will be easier for scientists to calculate the amount of particles going through the atmospheres
Water
On a lot of planets, a large amount of water can be found but is beneath a thick layer of ice and so is hard to get
Earth gives humans easy access to water
