I just found a month-old outfit on my computer that I never posted! This was a great excuse to stay in comfy clothes all day, and not having to venture outside to take outfit photos ;)
So this skirt is quite a special vintage piece because it's actually a hand-me-down from my Grandma, which I shortened. And I think that plaid skirts look awesome paired with suspenders - it's something I've been doing a lot lately, pairing them with a plain shirt and then throwing on either a neutral-coloured or patterned cardigan over the top.

shirt - Cotton On

Titan is Saturn's largest moon. Titan is really cool because it has a super thick atmosphere, and although it is a pretty cold place with a lot of frozen water, it has lakes and rivers made up of liquid methane on its surface. Like Europa (see yesterday's post), Titan could possibly also have a liquid water subsurface ocean. Titan currently has the highest rating (other than Earth) on the "Planetary Habitability Index". This means it is the second most likely world in our solar system to harbour life.
The presence of methane in the atmosphere of Titan is intriguing, because it is something which is normally depleted in an atmosphere unless organisms (like us guys on Earth) are constantly replenishing it. Two years ago, a space mission reported anomalies in the atmosphere, which could have been due to methane-producing organisms. But, it could have also just been volcanoes spewing out gas (read more about this finding and the debate here). Because of the extremely cold temperatures (an average day on Titan is -180°C), life as we know it would not be able to exist on Titan, but life totally unlike what we would recognise could be a possibility. Laboratory simulations have shown that there is in fact enough organic material on Titan to start a chemical evolution similar to what probably occurred on Earth.
The NASA spaceship Cassini is currently doing multiple fly-bys of Titan, trying to figure out if it has a subsurface ocean, and looking for other signs of life, but it won't be landing on the surface. There was a probe sent to the surface in 2005, but unfortunately it only kept sending data back to Earth for 90 minutes (the picture below shows the sole image of the surface that was sent back). There have been proposals for other probes that would last a lot longer than that, but nothing concrete has been put in place yet.
I hope you're enjoying these posts about life in the solar system. I think that if I wasn't doing neuroscience and biochemistry, I'd love to do astrobiology. There will also be a part three and four, so look out for them in the next few days.
