Hidden on the reverse side of the painting "Head of a Peasant Woman," which Van Gogh completed in 1885, was a previously unknown self-portrait of the Dutch painter staring back at them. The hidden self-portrait had been obscured by layers of glue and cardboard that had been attached to the back of the canvas; museum officials suspect the materials were applied sometime during the early 20th century to help protect the artwork for an upcoming exhibition, National Galleries representatives said in a statement.

The mine, located near Manchester in a village called Alderley Edge, was once a source of cobalt, an element mined for the brilliant blue pigment imbued on pottery and glass. Cobalt mining was a lucrative trade for England in the 19th century. But imports from other countries became cheaper than English cobalt, so this particular mine, owned by Sir John Thomas Stanley in the early 1800s, was abandoned around 1810.

But is that really true? In fact, is it possible to see any human-made structure from beyond Earth's atmosphere? To answer that question, first we need to define where Earth's atmosphere ends and outer space begins. The Kármán line, named after physicist Theodore von Kármán, is widely considered the boundary between Earth and space. Typically, it's defined as 100 kilometers (62 miles) above our planet's surface. So, what can be seen from that far up? On a clear day, would someone at the Kármán line be able to see the Great Wall of China or the Great Pyramid of Giza, for example?

The supply mission, named CRS-25, blasted off from NASA's Kennedy Space Center in Florida aboard a SpaceX Falcon 9 rocket. After just 2.5 minutes of flight, the first stage of the rocket detached, making a safe, upright landing five minutes later on SpaceX's drone ship "A Shortfall of Gravitas" in the Atlantic Ocean. The second stage of the rocket continued upward into orbit, propelling itself and the uncrewed Dragon resupply craft mounted on its nose.
