  • Science is all about genuine curiosity for what surrounds us. And I believe that if everyone on Earth embraced their true "scientific" nature many problems would be solved. To begin with all existing inequalities. Science tells us that that there is no difference between humans. It teaches us that, in the end, we don't live in the Universe because we ARE a...

  • Love it.

  • Great! Go for it.

  • Don't bother about the formula, all you need is the concept that lies behind it. ;)

  • I'm glad you're enjoying the course, Vicki.

  • That's what they did...with unmanned missions though. And the results were very interesting.

  • I think the history of this debate, about the existence of water on the Moon, is very intriguing. For any supporting proof, there was a proof against it. There seemed to be no peace.

  • I couldn't agree more with the last sentence.

  • I think that no science debate is really finished. Science is all about progress, and as we progress we get enhanced technology which can lead us to new discoveries, and everything we believe is put at stake again. Take an example quantum physics.

  • That's exactly what the scientific method is all about! Great!

  • Water is present in all our Solar System. That's interesting, because life as we-know-it thrives in water. I myself was very surprised when I wen through week 6 the first time I took this course.

    My favorite week :D

  • @AngelaL Great!!! :D

  • Seeing it really makes a difference.

  • Thinking about costs, I think the latter would be a better option. Once it's in orbit it stays there. Besides I think it's easier to dock spacecrafts in orbit rather than land them on the Moon, only to launch them again into space.

  • Keep up with the course's steps and you will find out.

  • What always amaze me are the timespans involved! We're nothing compared to them - we live, on average, 75 years. That's why Geology is important, it makes us understand these huge changes and movements of Earth's (and other bodies') crust.

    Hello to everybody and welcome to WEEK 5! This week is all about lunar geology! You might not like it as much as the other material in this course. There are a lot of notions to take in. However, bear in mind that geology is very important. Not only for a complete understanding of our Moon, but also to get a deep insight in the history of our every planet....

  • Don't worry too much about the result. As long as you're interested and you learn something new you're doing fine. :)

  • That's why they were cautiously "packed" for re-entry :D

  • I'm glad you liked it!

  • That's an interesting observation. It must have something to do with the location of the heat shield of the spacecraft, however this is an artistic rendering.

    Just have a look at this NASA video when you have some spare time. The whole re-entry science is explained and it's one of the most mind-boggling stuff I've ever seen. I love...

  • It does make you think a lot.

  • Great! Thanks @MarkGray :D

  • Indeed. Tectonic activity recycles the Earth's crust and the oldest craters are gone after some million years.

  • We're so lucky to have our beloved atmosphere. Not only it permits life to exist but it also protects us from all of these little asteroids.

  • Great recap of al the variables! Don't forget gravity is important as well to understand the scattering of the debris left by an impact.

  • Hold that thought, guys! You'll learn more about the lunar maria when we'll explore the geology of our moon during WEEK 5. Volcanic eruptions did play a role in shaping the moon's surface in the past.

  • More than the atmosphere is the planet's gravity that affects the most how the debris will scatter around the crater. Keep on going on and you'll know more in the next steps. :)

  • Crater-science, here we go!!

  • Hold that thought till Week 8. We'll cover more in detail what is life-as-we-know-it. It's essential to know exactly what life is before looking for it elsewhere.

  • It's great to hear that you like the material, guys!

  • Fascinating, isn't it?

  • I think it must do. Consider that Ganymede's magnetic field is embedded into the magnetosphere of Jupiter, which is 20,000 times stronger that Earth's. It begins to avert the Solar Wind 3 million kms before it reaches Jupiter.

  • The triangle of fire includes fuel, oxygen and heat. On Titan either heat and oxygen are not present. I think that's the reason why the atmospheric gases wouldn't ignite if electric storms were to exist.

    Learn more on the triangle of fire here:

  • Perfect!

  • I love that movie.

    Welcome to week 2! This week you'll discover how craters have a science of their own. I hope you'll like it. Enjoy!

  • Indeed.

  • Earth does wobble. It's a slow cycle called precession. Have a look:

    https://www.youtube.com/watch?v=adzx547ptck

  • There are indeed retrograde moons. Likely captured and not formed in situ. Triton is a good example.

  • Good! I hope you'll learn more and more from us. :)

  • I like your comment. The fact is that, for example, the Moon and the Earth are considered like a binary system that, together, orbits the Sun. The are indeed bounded gravitationally one to another.

  • @GeronKees Although without its regulatory influence on our axis, axial precession would make seasons way more extreme on our planet. :) I don't think it's necessary for life to exist, I just think the moon, in our case, helped a lot.

  • @RichardWright Thank you Richard! :)

  • Good luck with your first quiz! Don's stress, just have fun. :)

  • One doesn't learn this stuff at school. Love it! I hope you like the contents of this course. All free knowledge for you. Moons are indeed fascinating.

  • I don't know if anyone of has seen this BBC documentary, but it's mind-opening.

    https://www.youtube.com/watch?v=I1_TZqAO76A

    It's about the moon and its influence on life on Earth.

    I personally think life wouldn't have evolved the way it has without the stabilizing effect of our satellite. However, life is like a spreading and highly adaptable virus...

    Apparently, it's not only about companionship, but it's also about the very development of life and how our satellite influenced it. :)

  • Considering the whole Solar System is 5 bln years old, it would be interesting to know how this hypothetical life would have evolved until now. Look at how life has evolved on Earth. Great comment Geron, thanks! Keep it up!

  • When I first took this course I was very impressed that ice could behave like rock. Science is mind-boggling.

  • They do deserve a subject of their own. So much stuff to know and to learn.

  • You're in the right place!

    Hello!!! Welcome to everybody!! I hope you'll enjoy this course. It's fascinating.

  • Well, I run my own science page. It's called @scienceathand and you cand find it on facebook or on instagram. :)

  • Interesting the see the same story told by different angles. It's incredible how the reliability of the story can be affected.

  • Interesting brief history of cancer and its treatment here:

    https://www.youtube.com/watch?v=yWAFOZPIzUU

  • I would use the NHS website, cancerresearchuk.org, aacrfoundation.org and similars.

  • Be careful with wikipedia though ;)

  • I love Titan!!

  • It's amazing!!!

  • Indeed robots require less "maintenance" then humans do!!! That's the great advantage they have!

  • Geology is tricky sometimes. But don't worry, you're not alone. Many people, including me, struggle with recognizing samples and fully understanding the chemistry behind geological processes. However, as long as you keep your interest for our Universe alive, you are in the right place. Keep it up!!

  • Thanks, Ian. I hope you enjoyed using it.

  • Thanks for sharing, Lorna.

  • The radiometric dating gives you the "age" of the sample you are analyzing. Usually the samples we're able to analyze on Earth all come from the Solar System, which is approximately 5 bln years old, so they can't be older than that. If you found a sample, say, 10 bln years old, well, that surely wouldn't have been born in our Solar System.
    Besides, the Big...

  • Never say never! :)

  • Science is indeed impressive. I'm glad there are so many people out there (like all the participants in this course) who marvel at what we humans discover through science. Not everybody does.

  • I think you will like this:

  • I think it's got to do with the molecular shape of ice, which tends to crack following straight lines patterns.

  • Hello Katherine. Have you tried seeing the Brian Cox video in the link?

    (https://www.youtube.com/watch?v=LpjbdH1y_ds)

    Alternatively, check this out:

    https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment

  • Yes, it makes us realize we're very "small" after all in our world, compared to the giants out there!!

  • Life in the outer Solar System, below the icy shell of Europa. Or so I hope. :P

  • The best video of the whole course!!

  • I love the course supplements. I usually go through the course with my laptop and I use the supplementary pdfs on my tablet. It reduces a great deal the amount of notes I have to take down. Excellent idea!

  • Imagine the "D" shaped crescent Moon in London transitioning to a crescent "C" in Rio de Janeiro. Clearly you pass through a crescent "smile". :)

  • Don't worry Annette. You are all here to learn and we will always support you!! :)

  • Now you know why. :)

  • Not many people know this.

  • So had I.

  • What a great idea!!!

  • Great video! I've always loved it.

  • Anything orbiting something else is called a "satellite". I think we could use this word.

  • I like your point.

  • Definitely not easy to name them all.

  • Interesting observation.

  • You were a smart kid!! :)

  • Here explained the "dark" (we'd rather say "far") side of the Moon.

  • It's got to do with eclipses. Good comment, Joan.

  • Thanks for the question Andrew. Weeks 4-5-6 will be entirely dedicated to our satellite.

  • It's interesting how Maths is our Universe's language. Good question Joan. And good answers guys!

  • Great!! That's what we want!

  • I would suggest that you come back to this video by the end of the course to see if you better understand what you see. ;)

  • I doubt you'd rather go on Io. Eheh ;)

  • You'll see they can be spongy too. Keep on going on with the course.

  • Indeed. It's not something we're taught at school. Moons are a "world" of their own.

  • Loved the metaphor! A family album of our Solar System.
