One particular thing to bear in mind is that the timescales on Mars might be long - it's a quiet place, these days - and so it may just be that chemistry does these things naturally. As ever, much more work is needed but I'm still betting #itsneveraliens.

Following the K2-18b news, I’m wishing all my astro pals the very best of luck this week in dealing with the media and with slightly more fringe members of the general public on socials. #ItsNeverAliens

Alien abduction 😐 #ItsNeverAliens #OrIsIt

just had a lovely chat with the Beeb about 3I Atlas☄️ #ItsNeverAliens

Our two visitors are different: Borisov was a pretty typical comet, 'Oumuamua wasn't. Everything from processing of it by cosmic rays (likely?) to a hydrogen iceberg (maybe?) to an alien spaceship (#itsneveraliens) has been suggested to explain its properties. (4/n) 🛰️🔭🧪

Time for your daily dose of clickbait! News outlets just love to drop aliens into their article titles with wild abandon, don't they? #space #astronomy #itsneveraliens

I put together this handy flowchart to help you identify that thing you saw in the night sky! #astronomy #space #itsneveraliens

It's likely this was one of the bedrocks of the "It's never aliens" premise which has quite rightly pervaded astro sciences ever since.
How incredibly ironic that it was most likely wrong!

The Viking missions made it to Mars because the Great Galactic Ghoul was preoccupied. #space #Mars #itsneveraliens

In case anyone's wondering what's up with all the drones...

1) The type of cunt that would buy a high-level drone is the eaxct type of person to fly it near airways for attention.

2) Do you really think aliens aren't aware there are countries that aren't the USA?
