World’s most powerful telescope reveals best images yet of universe

Recommendable! One of the missions of this new telescope is to find asteroids that could potentially hit earth (then you have a real climate crisis if the asteroid is big enough and it's not anthropogenic).

Mapping the Universe at the Rubin Observatory in Chile

Very recommendable! Amazing stuff! This is one of the largest digital cameras ever built. It can capture a golf ball on the moon and shoots images very fast.
