This 429 million-year-old trilobite eye is similar to those of modern insects

Eyes don’t typically appear in the fossil record, but researchers were able to study the well-preserved and fossilized internal structure of a 429 million-year-old trilobite eye. Surprisingly, they found that the structure of the eye was nearly identical to the compound eyes of modern bees, dragonflies and crustaceans, according to the new study. The study…

Astronomers find galaxy similar to Milky Way more than 12 billion light-years away

Our Milky Way galaxy has a bit of a look-alike in an unlikely place: the early universe.
