Personally, I'm not really an expert but I'd like to give chance to the Vera C. Rubin Observatory cause of:

- It will probe the nature of dark matter by mapping and cataloging billions of galaxies through space and time.
- It will manage and effectively analyze an enormous output of data. By 2018, estimates had risen to 250 teraflops of computing power and 100 petabytes of storage.
- It is also hoped that the vast volume of data produced will lead to additional serendipitous discoveries.

 

and also of course to the James Webb Space Telescope, cause of:

- is unique, basically is the HST successor but in infrared radiation, and this says it all.
- its goal to search for light from the first stars and galaxies that formed in the Universe after the Big Bang.

Webb, if only so we can stop poking fun at the endless delays.  Also because it might finally find Planet Nine, if it exists.

Also, I love that names like Very Large Telescope and Overwhelmingly Large Telescope are an accepted naming convention for these things.

They will launch it in 76 days, do you think they will delay it again?
Probably they must be sure that all those thousands parts work correctly,
cause once it has been launched they can't no longer repair it, like they did with HST.

Ah, the Planet 9 aka Planet X. It probably does not exist, according to NASA:
"In 2014, NASA announced the news that its Wide-Field Infrared Survey Explorer (WISE) exploration program, after probing space,
ruled out the existence of a planet X."

And even if they found it, it will be immediately de-classed as dwarf planet.
Don't we have enough of Trans-Neptunian object already?

yay, when I tried to translate "overwhelmingly" in Italian, the word, using an euphemism, did not satisfy me very much.
It means " in modo schiacciante", so it is literally "in a crushing way".
So it is so big that it crushes you.

Planet Nine wasn't even theorized then

 

And it wouldn't be a dwarf planet as it's hypothesized *through* its very significant effects (assuming they're not an artifact) on its neighborhood, at a significantly higher mass than Pluto (and Earth). If they did call it a dwarf planet, it would be an actual case of the definition being bad and need reworking, as opposed to it being entirely appropriate for Pluto

Planet Nine, not Planet X. Planet Nine is a hypothetical super-Earth (or Mini-Neptune) in the outer solar system that could be responsible for the clustering of certain TNOs. Its existence was first proposed in 2016.

I made a bit confusion due to a bad wikipedia ENG-ITA redirect and the fact I realized now that there are 2 different planets: Nine and X.

Yes ok, you're right. I read that "On June 20, 2017, the University of Arizona claimed to have calculated that a certain type of perturbations in the Kuiper belt
could be caused by a body of similar mass to that of Earth or Mars."
So not dwarf, even if TNO.

Thx for this clarification.

yes sorry, as I said there is a bad redirect in these wikipedia pages that confused me a bit.

https://en.wikipedia.org/wiki/Planet_Nine (Not to be confused with the Planet X proposed in 1906 by Percival Lowell.)

then switch to Italian

https://it.wikipedia.org/wiki/Pianeta_X (Nel 2014 la NASA ha comunicato la notizia che ... (WISE) dopo avere sondato lo spazio ha escluso l'esistenza di un pianeta X)

then switch to English

https://en.wikipedia.org/wiki/Planets_beyond_Neptune#Planet_X
 

I remember to have read something about this Planet X on a science book when I was young.

it’s crazy how outdated this became because of all the delays.

the vera c rubin telescope has been delayed to like… 2028 or something but it was worthy enough to get an entire LSR body out of it… so there still is some hope.

We have to build a telescope on the moon.  We're going there anyway, and I'm interested in more than water.

[NFUN]

give us a bit more time to work on quantum networking and remote entanglement so we can build IR/optical interferometer telescopes before we really commit

What if every space craft had a module on it that was an element of a large and growing phased array antenna across all active craft.   Very accurate position and signal time stamping would be required but that is doable. 

Picking what band to optimize for would be the hard part as antenna element size could vary quite a bit
