We are left with a chilling vision of the sun turning into a Red Giant star as it expands - engulfing Mercury, Venus, Earth and Mars.
"The presence of debris means that the companion was either a red giant star or similar star that, prior to making its companion go supernova, had shed large amounts of material," said University of Washington astronomer Melissa Graham, who presented the discovery and is lead author on the accompanying paper accepted for publication in The Astrophysical Journal.
We'll start with one of the easier catches, NGC 7678, which is found 1.2[degrees] west of the pulsating red giant star 71 Pegasi (magnitude 5.3 to 5.6).
Sky watchers from the Middle East, Central Asia and Japan will have the best vantage point of seeing the moon eclipse the red giant star Aldebaran, which serves as the bull's eye.

The binary system usually consists of a white dwarf and a red giant star. If these two stars are close enough, material from the red giant star can be pulled off its surface and onto the white dwarf.
Thus, a red giant star is born--our sun will evolve into a red giant in about 5,000,000,000 years, and expand to engulf and incinerate Mercury, Venus, and possibly Earth.
