Krystalzkris:
wonder why i didnt take my physics and geography class serious.

hahn:


Do you think johnnydon22 learnt all this via the Nigerian schooling system? It's apparent that he is self taught

Krystalzkris:
your right,I also think he must have fallen in love with those subjects in school before trying to learn more on his own... I never loved those two subjects..

hahn:


It doesn't necessarily work like that. I was a science student in school but then fell in love with business. I had to start learning business on my own. If you have interest in something, nothing holds you back from seeking it

I was in love with physics, geography and biology in school but my interest in astrophysics developed later.

Its a fascinating and breathe taking subject that i can't help getting obsessed with, you are right it is self taught though and countless of such e-books on my phone nearly pass normal documents.

Astronomical twitter handles are my favourite handles to follow, no celebrity stuff..

My girl friend once asked me why i like all the planets, astroids, galaxies, nebulas and other astronomical and physics pictures on my phone.. that it is boring..

I had to create folder for them (more than 400) so she can leave that side alone when using my phone and not complain again... That girl sef...

Lol. A lot of women are not into those stuff. Neither am I.

I more of business prone. When I am eventually rich, I will love to create a science institute here in Nigeria. Maybe we can work on it together when it's time

When i use a nebula as my whatsapp dp like i usually do, she will be like

"Baby remove that thing and put my picture "

Hhmm science institution, sounds neat... future achievement dream things ba?

EUROPA

Next stop on the list we port to Jupiter.. No! No!! No!!! not the planet jupiter, that humongous beast is a gas giant so finding water on it is a long story.. Am talking about Jupiter's moons.

Europa is one of Jupiter's 4 main moons or Galilean moons as they are popularly called.

Europa has a beautiful icy surface with salty liquid ocean beneath this surface. The tidal heat of its beast parent planet jupiter maintains this water in liquid form.

Europa is slightly smaller than our moon, just a tiny bit smaller but is one of our best shots or should i say bets of having micobile alien life forms lurking within...

herald9:

What's water doing in a moon when planets needs it most?

johnydon22:

Lol.. Most of these Moons are massive enough to achieve hydrostatic equilibrium under their own gravity...if they were orbitting the sun instead of planets, they would have been classified planets

After all planets are not primary source of waters but Comets and Asteroids probably..

herald9:

Was wondering, since the moon is made up of particles that reflects light, the surface temperature will be hot, which means water will be evaporated faster than its taken in.

How is it able to retain water in its icy form?

Teempakguy:
I have a theory that the reason why mars doesn't have much water on it's surface is because of solar winds blowing away liquid water away from the planet over the millennia. i need someone to work it out mathematically.

my evidence is er . . . well, mars only has dense gases on it's surface right now. and a lot of sand. that is weathering. how did that happen? how is it possible for the surface of a planet to be so full of sand if there wasn't a consistent weathering system? and i recently read of how mars had all the lighter gases in it's atmosphere blown away by solar wind because it's magnetic field is very weak.

it follows that as the gases were being blown away, water must have evaporated due to the decrease in temperature.. these would have then being blown away as well.

johnydon22, what do you think of this?

johnydon22:


I doubt the solar wind hypothesis. . . We are much closer to the Sun than Mars and so i think Solar winds should have much effect on the earth than Mars...

So If solar wind had such effects on Mars, Why is earth still hoarding an enormous amount of liquid water..

(tho waters on Mars must have been far more older than what we have on earth..)

Alongside Mars having an ancient ocean before, it is also thought mars had a much thick atmosphere like earth..

What ever murdered those Thick atmosphere took the water with it.

My best guess is a Planetary Collision, Mars might have been a bit bigger than it is now, a collision with another planetary body e.g Asteroid Can really dismantle Mars' rich atmosphere remember Asteroids react like nuclear bomb on impact.

So i think It was a collision which evaporated the Waters in the process, peeled off most of Mars' atmosphere until we are left with what we have now..

Debris from that collision must have contributed to the debris in the asteroid belt..

Take a look at the picture of Mars i put up there, You noticed the huge scar on the planets surface?..

Might be remnants from the impact.. ...

Teempakguy:

The solar wind is actually very dangerous. and also, in space, distance doesn't matter. without atmospheric friction to reduce speed over time, things do not slow down at all. the solar wind will continue to move at the same speed . . . forever.
earth still has a lot of water because of our magnetosphere. which deflects the solar wind. like a force field.. another of those cool things.


Mars does not have a strong magnetosphere. because of this, the solar wind is in direct contact with it. no deflection. i think the reason mars doesn't have this magnetosphere is because of that collision you mentioned. it must have jumbled up the core very badly and must have destroyed it. a planet needs to have an intact core in order to have a functioning magnetosphere.

I don't think the collision is solely responsible for the stripping of mars' liquid water because, earth has also been involved in such a collision. which gave rise to the moon. and yet, we still have water. i think the worst the collision could have done was to
1. convert a lot of the water into gaseous form, instead of liquid,
2. destroy mars' magnetosphere,

the result would be an eventual stripping of water vapour and oxygen over the millennia. transforming the planet into what we now see.

here is a picture (artistic representation) of what is going on.




Another depressing fact. in the last 200 years, the earth's own magnetosphere has decreased by 15%. so . . . get ready, the earth is going to be loosing some weight in the next 5000 years.

johnydon22:


Very true about the Magnetic field that is why i proposed a collision which is the only that should be powerful enough to severe Martian magnetic field that much..

Our collision with the body that formed our moon should not be as big as that Mars could have witnessed.

The body must have been nearly half the size of Mars to powerful enough to diminish the planets size, severe it's magnetic field and slice it's atmosphere leaving the water and possibly life forms on it at the mercy of Solar Wind like you rightly postulated.

The scar on Mars points towards a humongous collision..

I think understanding what really happened to the Red planet would give us incentive on how to prevent Earth from suffering such fate anytime soon..
