The giant impact hypothesis is the most widely supported theory for how the moon was formed, with research in 2014 adding support to this theory over other possibilities. Now UCLA-led research reconstructs a massive crash that took place 4.5 billion years ago (abstract, full article paywalled), supporting the theory that the Moon was produced by a head-on collision between Earth and Theia, a forming planet.
We know space is big, but trying to understand how big is tricky. Say you stare up at the sky and identify stars and constellations in a virtual planetarium, you can't quite fathom how far away all those stars are (previously, twice). Even if you could change your point of view and zoom around in space to really see 100,000 nearby stars (autoplaying ambient music, and there are actually 119,617 stars mapped in 3D space), it's still difficult to get a sense of scale. There's this static image of various items mapped on a log scale from XKCD (previously), and an interactive horizontal journey down from the sun to the heliosphere with OMG Space (previously). You can get a bit more dynamic with this interactive Scale of the Universe webpage (also available in with some variants, if you want the sequel [ previously, twice], the swirly, gravity-optional version that takes some time to load, and the wrong version [previously]), but that's just for the scale of objects, not of space itself. If you want to get spaced out, imagine if If the Moon Were Only 1 Pixel, and travel from there (previously). This past March, BBC Future put out a really big infographic, which also takes a moment to load, but then you can see all sorts of things, from the surface of Earth out to the edge of our solar system.
Take a photographic journey into the past with Illustrated Past, which offers glimpses of life in Brittany, a trip to Tunis and Algiers, scenes of Dutch daily life. These examples are excerpts from the Dutch book, De Aarde en haar Volken (Project Gutenberg), or The Earth and its Peoples (Google auto-translation). Where the 1906 edition featured photos from around the world, the 1877 edition featured etchings (Gutenberg; Google translation).
From Earth to the Solar System (FETTSS) is a collection of images curated by NASA that portray an attempt to understand the origin and evolution of the solar system, by looking to the skies and investigating extreme situations on earth, like high-altitude lakes and an acidic river. [more inside]
