Who is staying in other planets ?

Question

Who is staying in other planets ?

Answer 1

Aiens live on other planets

Answer 2

  There are plenty of aliens staying on many planets.

Answer 3

The scientific answer is that we have no evidence (yet) of intelligent life on other planets. The sheer number of stars in the universe however make it likely that somewhere life evolved into intelligent species. Wil we ever contact them? Probably not, because of the vast distances we will not be able to travel. Even sending signals will take thousands of lightyears. So, good question, but trying to find intelligent life on earth is hard enough.

Answer 4

Mercury: Mercuatonians

Venus: Venionians

Jupiter: Juplins

Saturn: Saturnians

Uranus: Uranians

Neptune: Neptunians

Answer 5

gases, minerals rocks

....................but atleast not humans

Answer 6

I would assume that since we are living on a planet, the question should really be, where are the neighbours and why are they not visiting

I am staying on another planet, it will be difficult to prove me wrong

because the earth is really just another planet  

Answer 7

who is staying in other planets ?

1) no factual evidence yet

2) within otur own solar system if anything more than likely organic or bacterial life forms..

3) other planets in our galaxy, for example superearths, maybe intelligent species  - why not? we exist

Answer 8

E.T. and its family

Answer 9

Not humans!! maybe aliens

Answer 10

if the universe is made up of the same stuff would they be so alien

Answer 11

Imagination

Answer 12

some kinds of  lives... but exactly we don't know abt that? many  of planets  has methane... as per astrobiology microorganism can develope in methane.  

Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems to be of vital importance for the microorganism.

The researchers examined how a bacterium adapts to changing circumstances. The study focussed on the behaviour of the relatively simple methane producing microorganism Methanothermobacter thermoautotrophicus. In order to grow, this so-called archaeabacterium obtains hydrogen from the environment. However, the quantity of hydrogen, that is the food available, can vary considerably. The methane bacterium seems to use this to its advantage.

At high hydrogen concentrations, thus an excess of food, the bacterium grows as quickly as possible. In so doing the organism loses energy but at this point in time plenty of energy is available anyway. Furthermore, this wastage is a bonus as it results in the difference between the hydrogen ion concentrations inside and outside of the cell becoming smaller. Under these circumstances this is desirable, as otherwise a range of processes in the cell might cease to continue.

The observations confirm the prediction made in a mathematical model. That model, constructed by the Nijmegen research group, not only predicted that the methane bacteria would waste energy, but also how that would occur. At high hydrogen concentrations the microorganism would allow hydrogen ions to leak through the cell membrane. In this case the cell membrane would act as a sort of excess pressure valve.

The model summarises about 2000 different reactions in a small number of biochemical and thermodynamic equations. The researchers have now subjected the model and the assumptions on which it is based to extensive experimental testing. As had been assumed, the important reactions in the methane-forming process proceeded without energy loss.

Despite its relative simplicity, the model seems to accurately predict the behaviour of the microorganism. This implies that apparently complicated processes can in fact be determined by simple thermodynamic principles.

The researchers expect that this is not only the case for methane-forming bacteria but might also apply to other forms of life. This means that the research is not only interesting for microbiologists, but also for chemists, physicians, botanists and zoologists.
