So, just how do they know how far the stars are? Stellar Parallax (Friedrich Bessel, 1838) is a method that uses plain old trigonometry but is limited to only 400 light years. Standard Candles (Henrietta Leavitt, 1908) extends that distance to the far reaches of the universe using Cephied Variables (super bright twinkling stars). But you know what's more mind blowing than these inconceivable distances? The stars we do see are no longer there and are mere glimpses into the cosmic past.
Yep. Mind blown.
