Triton (One of Neptune's Moons)

Triton Neptune's largest moon.  It is the only moon in the solar system that orbits in the opposite direction than it's planet.  It consists of frozen nitrogen over a core of rock and metal.  This moon is apparently geologically active, it's surface is still young and has a tectonic terrains.  Triton's atmosphere is tenous nitrogen and some traces of methane close to it's surface.  The temperature on the surface is - 237.6 Celsius, that is pretty cold.  

 

Triton is kind of like the moons Europa and Titan.  It as complex molecules and nitrogen, just like Earth.  Did you know that nitrogen is a form of waste produced by living things.  These are signs are favorable for some life, except for the cold temperature.    

 

Neptune

Neptune is the farthest planet from the Sun.  It has 13 satelittes (moons), Triton was the first moon of Neptune's to be discovered.  Neptune's atmosphere is primarily composed of hydrogen and helium and some traces of methane.  The methane is what gives Neptune is blue color.  Neptune has the strongest winds of all the planets.  It's winds are as high as 2, 100 km/h.  WOW could you imagine living there!  Neptune's temperature can drop as low as - 218 Celsius, it can get this cold because it is so far from the Sun.    

The air of Neptune is extremely cold, with temperatures of -270 degrees to -380 degrees. The air is made of complex molecules, the same sort of molecules that we see coming out of cars on earth in the form of smog. Energy in the atmosphere comes from lightning, ultraviolet light, and charged particles.

This kind of atmosphere is very similar to the kind of environment in which scientists believe life began. But from prehistoric times until today, life on Earth changed, and now these conditions are no longer friendly for life as we know it.

The inside of Neptune is very hot and liquid-like, but the temperature is as high as 10,000 degrees.

Overall, the environment of Neptune sounds very unfriendly to life as we know it on earth.

So there may not be life in that planet now but maybe Neptune is just starting out.

Uranus

Uranus is the seventh planet from the Sun.  It is commonly mistaken for a star.  Uranus and Neptune have a different atmosphere than those of the larger gas giants Jupiter and Saturn.  It's atmosphere is categorized as a ice giant, it is mainly composed of hydrogen and helium and ice that is composed of  ammonia, water and methane.  It is one of the coolest (and I do mean temperature) in the Solar System, -224 degrees Celsius.    

So is there life on Uranus that is the big question for all planets?  

No one knows because we (human) haven't been there personally.  We sent the Voyager spacecraft which provided us with alot of data.  The conditions are very different from Earth so if there was life, the organisms would most likely be very different as well.  Scientist have found that Uranus has a rocky core which are covered by a deep ocean of  water.  We all know water in an essential part of live.  So maybe there are organisms growth, living, reproducing, evolving and civilizing the planet Uranus.    

Saturn

The planet with the Big Ring around it.  Saturn is fairly far from Jupiter, it's neighbor planet.  It 's also the second largest planet in our solar system, just a bit smaller than Jupiter.  Like Jupiter it is mostly made up of hydrogen and helium and has no solid surface.  Although all four of the giant planets have rings, Saturn is the only one that you can see through a telescope.  These rings are made up of small particles that orbit the planet like a moon does.  Saturn has many moons, most are the size of a small asteroid or comet.  The most interesting moon is Titan, which is larger than Mercury.  

Titan is the only moon known to have a dense atmosphere and surface liquid evidence.  The surface temperature is -180 degrees Celsius.  Because the temperature is so low the water would be solid ice,  but there is strong evidence for liquid hydrocarbons having flowed on Titan.  The atmosphere is %90 Nitrogen and there is no appreciable oxygen to breathe.  Even if there is no biology on this moon, the study of it could still tell us a lot.    

Jupiter

Jupiter, the large planet close to Mars.  In fact it is the largest planet in our Solar System.  Jupiter is classified as a gas giant (Jovian planet).  It is primarily composed of hydrogen with some helium.  There is a visible atmosphere and storms.  Jupiter has been explored by spacecraft, the latest spacecraft (New Horizons) exploration was in late February 2007.  In 1994 Shoemaker-Levy 9 collided with Jupiter.  This Comet was in many pieces ranging in size up to 2 kilometres in diameter and collided with a speed of approximately 60 km/sec.  Now with all this information do you think there could be life on this planet?

We know that the planet Earth was created with several impacts.  That is how it received the main elements for life.  Maybe Shoemaker-Levy 9 impacts brought all the essential element to start life on Jupiter.     

Mars

Mars is next to the planet Earth. Mars is bigger than Mercury but smaller than Venus and Earth. It has two moons that are too small to influence anything ( Earth's Moon influences tides). Mars has volcanoes, a cayon and polar caps. There is evidence of dried-up riverbeds. Astronomers believe that there was an ocean on the Northern atmophere. That is why there is less craters on that part of the planet. There have been soil samples taken, several landings and many photos of the planet have been taken. But humans have not yet visited this planet, it is below freezing, air pressure is very low, not enough oxygen to breath and no atmosphere to protect you from the harsh ultraviolet radiation from the Sun.

Earth

Earth, well we know there is life there! But there are organisms on earth that could help us understand the possibilities for life else where.

By Bjorn Carey

Extremophilic microbes are a wild bunch. They can be found thriving in some of the most hostile environments imaginable — swimming in near-boiling water, eating rocks, lounging in subzero temperatures and hanging out where radiation levels rival nuclear reactors.
They’re tougher than duct tape, boldly going where humans dare not and cannot.
Extremophiles are also a multimillion-dollar-a-year business — some of them are employed to eat oil and help clean up spills. Others have important applications in medical research. But for many scientists, these hardy microbes are interesting because they suggest the potential for life on other planets.

If such a organisms can live in extreme environments, then maybe there are organisms living in extreme environments else where.

Mercury & Venus

Venus on the other hand is a bit different from Mercury.  Venus is the second planet to the Sun.  Venus has thick clouds and an atmosphere that creates extreme greenhouse effect which bakes the planet up to incredible 470°C.  The atmosphere traps the heat from the Sun making this planet impossible to be lived on by humans or any other creates that live an Earth.  Or reasons for us not to be able to survive on Venus might be the fact that there is no water  or oxygen; the two most important factors of life for humans.  

Mercury & Venus

Let’s start with Mercury!  Mercury is the closest planet to the Sun, so you would it expect it to be the extremely hot.  In fact it the hottest AND coldest planet.  Daytime temperature is 425°C and drops down to -150°C at night.  There is no atmosphere to hold the heat in at night.  But the daytime temperatures are far to harsh your human to survive.  Mercury has no volcanic activity, no rain and no wind.  With all of these conditions there is no possible way anything from Earth could survive of this planet.  Now other life that we do not have on Earth is a possibility, but nothing has been discovered.

Welcome

Hey everyone I hope you will enjoy my blog.  I will be talking about the possibilities of living on other plants or there being life as we know it on Earth on other planets.  If you have any comments or question don’t hesitate to ask.
