Reply to comment by porcupineapplepieces in Uranus atmospheric changes while slowly reaching the Summer Solstice by daenel

Indeed! One of the main NASA decadal objective is an Uranus orbiter, we have already planned it. The mission should be launched in 2030 to reach the planet in 2040. The main problem is the fund, and it looks they don't want to invest in it, so, we risk to loose our once-in-a-lifetime chance to get there

Dark matter isn't regarded as "not interacting". We know about it because we see observations that don't make sense with the matter we can see.

For example this system has more gravitational pull than makes sense unless there is 25% more matter.

What's that missing matter - dark matter.

Personal I feel that we will eventually find that there is lots of "heavy dust" out there. Perhaps small but dense bits of rock and particle matter that just isn't that visible compared to giant less dense and bright hydrogen clouds.
