which heavenly body/bodies have/had the capacity to sustain life, besides earth?

Answer 1

Europa (a Jovian moon) and Mars are the best candidates in the solar system.

Mars had abundant liquid water billions of years ago, some simple life might still survive.

Europa is covered with ice, and there is believed to be an ocean underneath the ice.

Answer 2

Gliese 581c

A newly-discovered planet where life is thought to be feasible orbits Gliese 581, one of the nearest 100 stars to us, 20.4 light years away.

The new planet was found on 23rd April 2007 by a team led by Stephane Udry of Geneva University, The observatory they used was high in the Chilean Andes, where good viewing conditions would be available.

It is in the constellation Libra. It is the 87th closest star system to us. Its star (a Red Dwarf) is too faint to be seen with the naked eye, however. Its magnitude is 11.56.

What is unusual about Gliese 581c, amongst the 241 planets we have found orbiting other stars is

a) it is a rocky terrestrial planet not a gas giant

b) it is in the habitable zone i.e. with a temperature range at which water would be a liquid not ice. This is felt to be essential if it is to harbour life.

c) it has a radius 1.5 times that of earth (and a mass 5 x earth), the smallest yet,

(d) It orbits very close to its star (as the star, a Red Dwarf, is much cooler than our Sun, the planet needs to be nearer in to be warm enough to be habitable) and its year is a mere 13 Earth days in length.

There are two other planets in the same stellar system, one even further in (Gliese 581 b) a Neptune-sized planet of 17 Earth masses found in 2005 and one further out (Gliese 581 d) a planet of 8 Earth masses found in 2007.

The big question marks are:

(a) it is big enough to retain an atmosphere but is it breathable by humans?

(b) does it actually have (a plentiful supply of) water?

(c) how would we get there? (our present fastest rockets available would take 300,000 years)

(d) is the planet gravitationally locked to ts star, such that the same side of it always faces the star?

Many of the questions people will inevitably ask can only be answered when we can send an unmanned probe there. Meanwhile other planets will be found even nearer to us. (We know of a planet 10.5 light years away around Epsilon Eridani (the 9th nearest star) and 3 around Gliese 876, 15 light years away.)

Wilhelm Gliese was a German astronomer, best known for the Gliese Catalogue of Nearby Stars that he compiled.

Answer 3

Given the vast reaches of space, you may conclude that the odds are in favor of another planet existing somewhere that has the same atmosphere & components of our Earth. Alas, it has not been proven that any other heavenly body has or had the ability to sustain human life as we know it. Only conjecture at this point.

Is life elsewhere? Three possible scenarios exist:
1. Life evolved elsewhere from the same microbial beginings as defined in the theory of evolution.
2. Life was transplanted there from another planet.
3. God created life there as may have happened on Earth.

So any way you look at it, if it happened here, it is possible to have occured elsewhere.

Hope that helps you,
Have fun!

Answer 4

Millions perhaps, in the other side of the Milky way, or another galaxy. Until we can perfect terraforming or biospheres (or a decent space program for that matter), we'll just have to be content with our planet.

Answer 5

Very good question. There are some interesting theories that mars once had life. No proof yet

Answer 6

It all depends how you Consider what life is designed as.
It you consider life as anything that has motion ,than the life on planets are atoms.

Answer 7

probably billions, if you consider that our puny little solar system is on the outside edge of a minor galaxy in a universe that has millions more galaxies

Answer 8

it is believed that mars had water on its surface billions of years ago so it probably had life.

Answer 9

None that we know about, so far.

Answer 10

Well, hi n CONGRATULATIONS, SHACHI!!!!

92.4% is great…
N u r blessed too. Expecting 60/70 n getting 84…….
