There's many a new telescope coming online for all of in, on, around and above our Earth...

Let's see what they see?...


Here for a good start is:

Mysterious dark matter mapped in finest detail yet
wrote:
... described as the most detailed ever map of the influence of dark matter through cosmic history. A telescope in Chile has traced the distribution of this mysterious stuff on a quarter of the sky and across almost 14 billion years of time.

The result is once again a spectacular confirmation of Einstein's ideas...

... dark matter influences the large scale structure of everything we see - where all the galaxies are, where the voids in space are. It's the scaffolding on which the visible structure of the Universe is hung. It neither emits nor absorbs light. The only way you can very obviously infer its presence is through its interplay with gravity...

... the [Cosmic Microwave Background] can be decoded to reveal all intervening structure on its journey to us.

There have been "gravitational lensing" detections similar to this in the past, most notably by the European Space Agency's Planck observatory a decade ago. But [Atacama Cosmology Telescope] surpasses all in terms of resolution and sensitivity...

... "It's one of the 'cosmic tensions' we all talk about," said Prof Jo Dunkley from Princeton University, US. "But with this new result, we find exactly the right amount of [expected] lumpiness - no tension! So, if there is a tension, it is something that appears in the galaxy data - not in ours,"...



Only a theory?...

It's what our Universe and we ourselves are made of!

Fantastic stuff!!

And for another new biggest bestest telescope yet in space, go self-healing liquid metal!


What is the Fluidic Telescope?


Fantastic way to go!
