Howdy howdy and happy Monday, everyone! :D

For this week's community question, I thought I'd go a bit more broad with the parameters. To put it lightly, I am a big fan of Jupiter. Honestly, I wish I had a more fascinating reason than this: It's just a ridiculously huge planet. I mean, it's MASSIVE. Anyway, that's enough to amaze me.

So, what about you guys? What are your favourite celestial objects and why?

Remember, we'll be featuring some of our favourite answers on the weekly community round-up!

So many possible answers. To pick just one,Mars, because its the next place people will set foot on.

Big and beautiful and best! What is there not to like about the Big Dog on the block? I think Jupiter has been overlooked as a suitable environment for life. Pressure, temperature and chemical conditions roughly 150-200 miles below the cloud tops on Jupiter are remarkably similar to conditions in sediments under abyssal basins on Earth. These sediments deep under the oceans are very low in oxygen, low in water and chemically harsh. Yet these sediments are the comfy home for AOA Archaea microbes (Ammonia Oxidizing Archaea). These microbes are everywhere down there, and because 70% of the Earth is covered with ocean water, these Archaea are the most numerous lifeforms on Earth as well as the greatest total mass of any lifeform. There is nothing to stop these same microbes from living in the atmosphere on Jupiter.

"Science begets knowledge, opinion ignorance.
"conditions roughly 150-200 miles below the cloud tops on Jupiter are remarkably similar to conditions in sediments under abyssal basins on Earth."
