We can"t see the first stars yet, but we can see their direct descendants
If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations of stars after that. So ou.....»»
Photonic crystals could be exactly what Breakthrough Starshot is looking for

Webb identifies tiniest free-floating brown dwarf
Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. In a quest to find the s.....»»
The positions of stars on an ancient navigation device tell us when it was made
Astrolabes serve two purposes. First, they are useful as an astronomical tool, especially for finding a ship's latitude. But second, they are works of art in themselves. Besides having to be precise, many are beautiful. They are even seeing a resurge.....»»
Discovery of magnetic liquid crystal: First direct observation of spin quadrupole moments in a spin-nematic phase
Liquid crystal is a state of matter that exhibits properties of both liquid and solid. It can flow like a liquid, while its constituent molecules are aligned as in a solid. Liquid crystal is widely used nowadays, for example, as a core element of LCD.....»»
