Delta Cephei: Astronomy’s Royal Gem Fit for a King
The variable star Delta Cephei lies in the constellation Cepheus and is a one of the most important and historical stars in astronomy. Delta Cep makes the basis for all Cepheids, which Henrietta Leavitt discoveed that their luminosities are directly related to their periods of pulsation. This led to our being able to measure greater distances starting when Edwin Hubble uncovered the distance to the Andromeda Galaxy after finding a Cepheid in the galaxy.

Barnard’s Star: Chasing the Red Dwarf Through Ophiuchus
Barnard’s Star, located under six light-years away in Ophiuchus, is a red dwarf with a surface temperature of 3,200 K and extraordinary proper motion, moving over 10 arcseconds per year. Discovered to host four exoplanets, it fascinates astronomers as a rare opportunity to observe significant stellar movement within a human lifetime. Article shows a photograph of it in 2019 amongst the stars. The star is also known as Runaway Star, HIP 87937, LFT 1385, Proxima Ophiuchi, V2500 Ophiuchi.
