Euclid meets launches this weekend.
The EU Euclid mission to study nature of dark energy and dark matter. is due to launch this weekend.
Euclid is an ESA mission to map the geometry of the Universe and better understand the mysterious dark matter and dark energy, which make up most of the energy budget of the cosmos. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion of the Universe. [1]
There is also a comprehensive launch kit available [2] in English and other languages from.

The Universe May Have Started with a Dark Big Bang
Interesting article from Universe Today. This was posted to Fediverse by DeborahJRoss.
So if I understand this correctly normal matter (protons & Neutrons) formed at the same time as Dark Matter but the Dark matter evolved separately via a second big bang which produced the dark matter.
If this sounds confusing, then welcome to the world of cosmology, but it still really interesting.

Dark Matter Galaxy
We are always finding something new in the Universe. This is a discover from Chinese astronomers, who have found a dark galaxy 2% Hydrogen and 98 % dark matter.
There is another Mastodon post here, with a link to the paper and more information on the FAST observatory.
