Nightscapes, Winter Outreach, and Wolf-Rayet Stars
In the February 2023 issue of Sky & Telescope, Alan Dyer shares his tips and tricks for creating incredible nightscapes and stunning panoramas. While we’re capturing bits and pieces of the sky from Earth, the European Space Agency’s Gaia mission is mapping stars along the entire celestial sphere. We’re covering the enormous contribution this space observatory has made to astronomy so far. Even as Gaia takes us into the future of star maps, we’re celebrating their history with a look at the astronomer who introduced 16 of our modern constellations. From constellations to star maps, we’re on the path to an improved picture of what our galaxy looks like from the outside. Recently, astronomers charted a previously unknown structure, a bridge between the Local Arm and the Perseus Arm that they’re calling the Cepheus Spur.
These rare jewels create powerful winds and mesmerizing dust spirals.
