Lyra's Double Double Star (all night)
The constellation of Lyra is positioned high in the eastern sky during late evening in June. Keen eyes might reveal that the medium-bright star Epsilon Lyrae, which is located just a finger's width to the lower left (or one degree to the celestial east) of the very bright star Vega, is a close-together double star. Binoculars or a backyard telescope will certainly show the two stars. Examining Epsilon at high magnification will reveal that each of those stars is itself a double - hence its nick-name, 'the Double Double'. Each duo is a true binary star system, with the companions orbiting one another once every 600 and 1,200 years.
