John Seach of Chatsworth Island, New South Wales, Australia, discovered a nova in the constellation Sagittarius last month. The University of Liverpool confirmed it as Nova Sagittarius 2015 Number 2, estimating gas being ejected at more than 6.2 million mph (10 million km/h). This is the brightest nova in Sagittarius since 1898 and brightest elsewhere in the sky since Nova Centauri 2013 peaked in December 2013,
While you are out, be sure to look for Saturn up and to the right of the orangey star Antares (Greek for “rivaling Mars”, which it is often mistaken for). Those binoculars or small telescope can reveal Saturn’s rings that are tipped toward Earth (and will be for the next 10 years).
If you prefer evening to pre-dawn hours, the International Space Station will again be visible over central North Carolina this week after sunset. Monday look to the west at 8:47 p.m. for a pass lasting a little more than 5 minutes before setting in the NNE, on Tuesday look WSW at 7:53 p.m. for a pass reaching 43º above the horizon before setting in the NE 6 minutes later, and finally look to the WNW.
