A few months ago I was watching a YouTube video which steered me towards the topic of this post. I am a (very small time) youtuber myself, and spend a lot of time looking for ways to tweak my content and make it more polished. The YouTube video mentioned above was made using screen capture software and the simulation package Universe Sandbox. The video featured all kinds of hypothetical scenarios being imagined and allowed to play out within the simulation. For example, the questions were asked: what if Saturn was moved closer to the sun? What if Earth passed through its rings on this inward journey? What if Saturn and Jupiter made a close approach to each other?
It was fascinating to watch. Simulating actual physics and real world parameters you could see what actually could happen if such scenarios actually took place. It got me thinking about my own video content, and about these simulation software packages. I of course had to get my hands on some!
Currently I am producing videos using both my laptop and my smartphone. In this post I will focus on the capabilities of a smartphone to produce videos about outer space.
Animations for this video were produced entirely on my smart phone, using several apps available on Google Play. My phone is an Android device, but I’m assuming there are equivalents over at the enemy camp.
First off, these apps are great educational tools. Perhaps where they are the most effective is getting people to explore from the palm of their hand. In this device obsessed era this is a big deal and also a drawcard for the digit generation. This video explores some mobile apps I’ve been using for my YouTube channel. It’s really amazing what you can do with amazing most nothing! I’ll also include a video about Uranus. All of the planetary animations came from mobile apps.
The Uranus video:
Here is another earlier video briefly introducing the moons of Mars…
And in this one I discuss Enceladus and some promising signs of habitability there:
These videos were extremely easy to make and perhaps the point of this post is that anyone can communicate something they care about. Enjoy!
Hi all. It’s been a while I’m ashamed to admit. I’ve been working on a new Facebook group to raise the profile of my channel. It’s been fun. Here is the link (hint: join the group!)
Here is my newest video. A basic breakdown of what exactly the Goldilocks (or circumstellar habitable) zone is, and it’s importance to life on Earth. If you like the channel please subscribe!
I’ve also provided the script/transcript for my upcoming episode of “Astro-Biological:”, which introduces us to the concept of the Goldilocks Zone….
G’day! Welcome to Astro-biological:!
Ben what the heck are you talking about? What’s the connection?
Let’s go check out THE GOLDILOCKS ZONE!!!!
Life, as I like to remind you, is really special. Here on earth, life exists only because certain conditions are met. Today, we’ll consider water. Everything needs it, but it only exists as a liquid at the surface here on Earth.
So? Big deal right?
Well it is actually!
Check out the sun. Giver of life! Driver of climate! Pumping out some pretty respectable energy. How much?
1 yottawatt equals 10 with 26 zeroes after it!
Brutal! And the sun is a pretty average star! Nothing special about it!So there’s plenty of sunlight for everyone!
Could other planets benefit from the sun’s golden goodness the way we do? Let’s take a look at the inner planets. They’re the only ones that really matter in all this…
Let’s see…Mercury, Venus, Earth and Mars. The rocky planets. The so called “Terrestrial Planets”.
Mercury is 58 million kilometres from the sun. That’s really close. This close proximity has turned Mercury’s surface into an oven, where liquid water couldn’t possibly last.
Let’s visit the next in line: Venus. Venus is similar to Earth in composition, gravity and size. Long ago Venus might have had oceans just like Earth, but again the planets closeness to the sun and other factors saw all that water disappear into space. Venus is now the hottest place in the solar system. Definitely no liquid water there anymore!
Wanna know more about what happened to Earth’s twin? This guy I know made a video!
Earth! Beautiful Earth. Our home. Every thing’s home actually. Eighty per cent of earth’s surface is covered by liquid water. There’s so much spare water here that our bodies are mostly made up of it! It’s absolutely everywhere, even locked up deep in the earth’s crust! Enough of earth. We’ve all been there.
Next planet out:
Mars. The cool planet. Every one wants to go here. Pity it’s so cold! Liquid water may exist here in tiny amounts, but most of the red planet’s water is locked up as ice or permafrost just below it’s surface. Plenty there for future colonists to use, but nothing readily available for biological processes. Pity. It’s a beautiful planet. Just ask Matt Damon!
So what is the Goldilocks Zone then?
Here’s the inner solar system. Mercury, Venus, Earth and Mars. Let’s visit a special guest who can explain the Goldilocks Zone for us…
ChefBenbit. (Watch the video when it’s up!)
Nice work Chef! So, if Earth was a bowl of porridge it would be the one Goldilocks ate: the one that was just right! it’s that simple! Earth is lucky enough to be at the perfect distance from the sun, where water likes to slosh around in liquid form. Things would be a lot different here if that wasn’t the case.
So that’s it for now! A simple but important piece of information. The Goldilocks Zone!
How am I going so far?

Thanks for watching astrobiological. Giving you the universe in plain human. Ciao!
Hi all. This post is essentially the script for a YouTube episode I have coming up on my Ben’s Lab channel. Like the “Holiday on Venus” episode, this one also is meant to depict a TV or radio presenter, outlining a vacation package across the solar system. Zip on past this video if you like, but it provides a bit of continuity for the script.
“Do you love risking life and limb? Do you think extreme sports is the perfect way to relax? Well then strap yourselves in! Did you love your trip to Venus! Venus is the testing ground for the Apocalypse! Not for the faint hearted!
If you thought Venus was hardcore, and you’re thirsty for more, Time-X has the ultimate vacation package for you! A grand tour of the craziest places in the Solar System! Let’s go!!!!
Mars! Been there, done that, I know, but have you seen a REAL Grand Canyon! Valles Marineris: the longest Canyon in the solar system! Not only the longest, but the deepest!
Those guys in Norway back in the old days… thought they were pretty cool jumping off cliffs, here, swooping down gracefully in their seagull suits! How do you think they’d like to jump into this bad boy! At 2485 miles long, there’s plenty of parking! That’s the distance from San Francisco to Washington. Or, just a bit more than the distance from Sydney to Perth! Holy Frehole! Not only is this canyon long, stretching a quarter of the way around Mars, it’s deep: 7 km deep in places. Hooley Dooley! Cliff jumpers will go insane for this place!
Should we tell them there’s almost no atmosphere on Mars, and they’ll drop like stones?…..Nah!
Still on Mars!
Enjoy a sunrise atop Olympus Mons. Sounds lovely! At an altitude of 21.9 kilometres! That’s pretty tall! How tall is Mount Everest in comparison? Do we even care? Look, look at the little poopoo! Nawwww!!! Olympus Mons is an extremely ancient shield volcano, which has long since become extinct. Climbing its slope, you’d actually be virtually standing in outer space once reaching the peak! What’s not to like about that?
Moving on… ahem!
Next stop, Vesta, a lovely little chunk of prime real estate in the Asteroid belt. Boasting lots of peace and quiet and some really epic views, Vesta has the tallest mountain in the Solar System: Rheasilvia.
Plopped right in the middle of a gigantic crater that takes up 90 percent of the diameter of Vesta, this monster was formed by a meaty impact with something really big and mean around 1 billion years ago. Sorry Olympus Mons, Rheasilvia is just a little bit higher than you, at 22 km.
Let’s head further out! Where are we now?
Io, orbiting Jupiter, is the most geologically active object in the solar system! Did someone say geology? That doesn’t sound very extreme, you say. What does that mean for the extreme sports nut? Well, Io has 400activevolcanoes! 400! Ride your mountain bike down one of those- there’s no shortage of them! Just ride really fast! This place is a little bit too extreme! I’m not hanging around for that!
We haven’t forgotten water sports! Europa is the place to go for extreme deep sea diving! Back on earth the deepest point in the ocean is the Marianas Trench in the Pacific Ocean, which gets to 12 km below sea level. You could hide majestic Mount Everest inside it. Poor Everest, a little bit inadequate today!
Europa orbits Jupiter, and looks pretty serene, but that pretty icy shell hides an ocean averaging 62 km deep! I’d like to explore that myself! Just be mindful though, extreme sportsters; Europa may have it’s own life. No littering and no feeding the natives!
That’s some pretty serious water! On to our next stop: Neptune and Uranus!
If extreme weather is your thing, then line up! Go hang-gliding in these winds! On Uranus, winds in the upper atmosphere blow along at over 900 kph!
Stop the world, I wanna get off!
But wait, there’s more!
On Neptune, similar winds scream along at a brain splattering 2100 kph! Just think about it. Whiplash from hell, anyone?
If you still can’t get jumping off rocks out of your system, then you will LOVE Miranda, one of the moons of Uranus. What’s so great about Miranda?
Only the TALLEST CLIFFS IN THE ENTIRE SOLAR SYSTEM!!
For some colon twisting thrills, these cliffs fit the bill. At 20 km deep, it’ll be a real high jump! Thing is though, we offer this jump to newbies. Why? Because with Miranda’s tiny gravity, it’ll take 12 minutes to fall to the bottom! You’ll hit pretty hard, at about 200 kph, but a tonne of bubble wrap will get around that! We do give a Seniors discount for this jump.
Well those places are nasty, no doubt, But never let it be said that we at Time-X are not discerning purveyors of the ultimate in bowel clenching excitement!
Let’s leave the Solar system altogether! Hurry up! It’s 63 light years away!
The perfect way to say “I love you” to the raving psychopath in your life!
Exoplanet HD189733B (Catchy name, I know!)
This place eats the others for breakfast. Uranus and Neptune are super windy, but they’re just farting compared to this place. Winds reach speeds of 5400 miles per hour, or 8690 kph!! Oh my gosh! AND it rains glass!! Sideways!! If you’re still keen to visit, put your affairs in order and say goodbye to your loved ones, because that’s what extreme sports are all about!!
Places on this trip are going fast! Mind you, we have a slightly high turnover, so you don’t really have to wait too long for a seat. Call now.
