What we still don't know about the Universe could invariably fill most of the empty space in the Universe! That is changing, however, because of the likes of the "Spitzer Space Telescope", the Hubble Space Telescope, and the newest telescope, the James Webb Infrared Space Telescope...
The James Webb Space Telescope has yet to be commissioned into official service and it will probably happen somewhere in the June/July 2022 time period... That said, the JWST has already garnered a tremendous amount of data, imaging and more of deep space and the celestial objects like Galaxies, Planetary Nebulae, Star forming Nebulae that heretofore have never been seen in such magnificent detail...and it has only begun to scratch the surface, so-to-speak, in its primary mission...
For reference I provide you with a bit of information on three of the more important telescopes...
1) "The Spitzer Space Telescope, formerly the Space Infrared Telescope Facility, was an infrared space telescope launched in 2003. Operations ended on 30 January 2020. Spitzer was the third space telescope dedicated to infrared astronomy, following IRAS and ISO." - Wikipedia
2) "The Hubble Space Telescope is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy." - Wikipedia
3) "The James Webb Space Telescope is a space telescope designed primarily to conduct infrared astronomy. The most powerful telescope ever launched into space, its greatly improved infrared resolution and sensitivity will allow it to view objects too old, distant, and faint for the Hubble Space Telescope.
- Launch date: December 25, 2021
- Dimensions: 20.197 m × 14.162 m (66.26 ft × 46.46 ft), sunshield
- Cost: 10 billion USD (2016)
- Bandwidth: S-band up: 16 kbit/s; S-band down: 40 kbit/s; Ka-band down: up to 28 Mbit/s
- Launch mass: 6,161.4 kg (13,584 lb)
- Power: 2 kW
- Manufacturers: Northrop Grumman, Ball Aerospace & Technologies" - Wikipedia
However, In the technical scheme of things from a global perspective there have been a plethora of different types of Telescopes launched into space for specific purposes with the mission to gain as much information as possible for Scientific Study of our Universe!
Kindly watch this video in FULL SCREEN ON THE LARGEST SCREEN YOU HAVE AVAILABLE! Anything smaller than a 14 inch laptop or monitor will not have the same technical effect for the viewer...
I hope you all enjoy this Astronomy video,
Kerry

We've already sent different types of messages out into space for space aliens to intercept and interpret. Why don't we just wait for space to come to us, I think it would be a lot cheaper.

IF all Messages sent in to space traveled at the maximum speed of light (speed of light in a vacuum is 186282 miles per second (299792 kilometers per second), then a message that might be received at Proxima Centauri B, would take 4.2 Light years to get there...(and that is the closest exoplanet to Earth), then the return message would take another 4.2 light years... It might be cheaper, but for exoplanets in the range of 20 to 30 light years away would take up to 60 light years round trip and obviously the further away from Earth would take longer... Meanwhile we may be contacted by Extra terrestrials who have overcome the standard laws of Physics, and they could be intent on making Earth their new home and wipe us out... So what is the real cost? It's really speculation...at this point.

Sgt (Join to see) Boy, with that answer you made my head spin, and I think I was boosted out into outer space.

Hahaha if they knew what was good for them they would ignore us. Earth is a shit show

yes much we don't know about the Final Frontier, perhaps if we can get the enterprise up and running could give us a few more answers.
