Seeing Red

Fourth planet from the Sun and named after the Roman god of War. Next in our series of planets we are going to talk about Mars (I promise Earth will be here as well). It is the last of the four terrestrial planets in the Solar System, again these are the rocky ones instead of the gassy ones. Mars is a lot smaller than Earth only having about a 1/10th of the mass (if you imagine all the dry area on the Earth, that is how big the surface of Mars is). The red colour of Mars is caused by Iron being oxidised, you know how metal left outside can rust? This is pretty much what happened to Mars!

Mars doesn't have a very strong magnetic field, which suggests that the core of the planet has stop being as active. It also means that some of the atmosphere of the planet has been stripped away! Mars has the biggest known volcano in the solar system called Olympus Mons (it is almost two and a half times bigger than Mount Everst!). It is one of the only bodies in the solar system that we have observed water on! In all these pictures you can see that Mars has a North Pole like we have here on Earth. Recently we have found evidence to show that there was probably once rivers and seas on Mars, does this mean in the past if could possibly have had life on it?!

 Mars is one of the most heavily explored planets in the Solar System with over the Curiosity Rover being the most recent one launched. It landed on the Gale Crater of Mars on the 6th of August, and has a whole host of instruments on board to help it explore. It was safely landed on Mars using a sky crane (yeah, sky crane, how cool is that?!), Curiosity was suppose to run for only 2 years but due to the success of it, it has been extended indefinitely!  

Curiosity taking a selfie on Mars..

Mars is a pretty big topic to cover in just one post, so I will definetly come back to it. This is just a bit of an intro to it!
What do you think? Coolest selfie ever?


  1. interesting post dear !! i love your blog !! its so much science and i love science :) xx

  2. This is a really interesting blog! Astronomy mixed with everything that a young girl likes!
    I don't want to offend anybody, but it isn't usual find girls with interesting interests hehe so I really appreciate when a girl have further ideas than fashion, beauty or boys (and I have to admit that I also like fashion, beauty and boys :) )
    I like astronomy a lot, but I don't know so much about it. I'm glad that you make this blog.
    I follow you from now!


    my blog is this one, maybe you want to see it:

    1. Aww thank you! I love beauty, fashion and boys as well, but we are all so different! Astronomy is just such as interesting subject :D

  3. Do they have any ideas are to why the core is no longer active? Def can't wait to read more about Mars!

    1. I think one of the reasons is that Mars has a much smaller mass than Earth, and they are about the same age, so it could just be that. One of the only reasons we can kinda guess this is that the magnetic field on Mars is a lot less than what we think it should be!

      Thank you so much for the comments!


  4. Really interesting post, I've just been reading the rest of your series too - so fascinating! :)x
