SOFIA Reveals New View of Milky Way’s Center


NASA has captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning a distance of more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.
 
I still think watching the SpaceX booster rockets land is one of the most amazing bits of engineering. All those guys in the pre spaceflight era depicting rockets landing on their tails, assuming some are still around, must enjoy that.

The pair landing simultaneously side-by-side last year when they launched the Tesla was one of the coolest things I've ever seen.

I remember watching it with my then 3 year old. I think we were both equally astounded.

A few years back some findings were published based on lunar rock analysis that suggests the moon had a volcanically outgassed atmosphere about 0.01 atm. It doesn't sound much but that's more than Mars has today and it's thought to have lasted around 70M years. That would be enough for water vapour to move around and settle in the colder places.
 
He's a bit of a buzzkill, but does a pretty good job laying out the reasons we have not seen a manned Mars mission to date.

 
Mars is no place to go unprepared. The radiation from the sun and CRP won't do you any favours at all. Elon envisages colonists living in glass domes. Personally I don't see it, I think the first people there will need to be looking for old lava tubes or something to cower inside of. Mind you, he also thinks nuking the poles will help "terraform" it.

And now Werner Herzog chiming in with we shouldn't be living there even if we are prepared:
In an interview with Inverse, Herzog described Musk's dream of colonisation as "an obscenity", and compared humans to locusts, emptying one planet of resources before moving on to the next.

As an aside, his new documentary on meteorites is very good. I watched it the other day and thoroughly enjoyed it.
 
So I'm a bit on the fence. If Mars turns out to be truly sterile then I have no real qualms with colonising it. If it is host to any native life then I'm not so sure. Except the only way we'll ever know for sure is with human exploration, which would almost certainly result in contamination.
