I gazed at the full moon, hanging low and bright oe’r the trees last night, warm and inviting on that September night. The late summer sky is no less beautiful now than when it was at the beginning. The moon, with the southern stars of summer, Antares in Scorpio and Sagittarius to the east, are[…]
Supernova 1987a was the closest supernova to be observed since Kepler’s supernova in 1604. It was one of the first objects observed with the newly deployed Hubble Space Telescope in 1991 and thus, the first -and closest supernova- to be observed with a modern observing platform. Although it is named and designated according to the[…]
This is the fifth installment of our ten-part series on the brightest stars and, with it, we’re pleased to present the red supergiant star, Betelgeuse, the right shoulder of Orion, the hunter.
