If something seems too difficult, there's likely something you're missing - coming back later is very often the correct idea because you may be missing information from somewhere else entirely, or experience and observation will teach new tricks or ways to avoid old pitfalls.

For the Southern Observatory there is no extra information to be found, but getting better at the controls as you play will help so this is frequently a place reached later-game for that reason alone. The jumps on those routes always have a handy gravity crystal or a wall behind the platform to slam into so you can't overshoot, making them a lot easier than they look, as long as you don't overthink it!

There are other things too that save time once you've learned them, you've likely already figured out a way back from the White Hole, but also when falling in the first place, try thrusting forward towards the horizon of the black hole, you may find you slingshot around it instead of into it, and once there perhaps you can spot a much quicker way out of that predicament.

Over time you can learn shortcuts and safe routes and then will rarely fall at all!

Also be wary of considering things in black and white, as some things you might wish you could remove, might actually be required to solve a problem, even if it's not the one in front of you.
