Paleontologists have found three lacewing larvae with large forward-directed stemmata (eyes in holometabolans) in 100-million-year-old Kachin amber from Myanmar. These specimens demonstrate the convergent evolution of highly developed simple eyes in at least two additional lineages of lacewings, showcasing the enormous diversity of lacewing larvae in the Cretaceous period.

The Sun as seen by Solar Orbiter in extreme ultraviolet light from a distance of roughly 75 million km. The image is a mosaic of 25 individual images taken on March 7, 2022 by the high resolution telescope of the Extreme Ultraviolet Imager (EUI) instrument. Taken at a wavelength of 17 nanometers, in the extreme ultraviolet region of the electromagnetic spectrum, this image reveals the Sun’s upper atmosphere, the corona, which has a temperature of around a million degrees Celsius.
