According to the space agencies, NGC 2022 is a red giant star
. Massive stars or those that are like the Sun enter this stage when they can no longer convert hydrogen into helium inside their cores.
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.
"Our sun will one day balloon out to become a red giant star
, wiping out Mercury and Venus and maybe Earth, before it becomes a white dwarf," lead author Boris GEnnsicke, an astronomer at the University of Warwick, told Space.com.
ISLAMABAD -- Chilean astronomer Maritza Soto has discovered a planet three times as large as Jupiter orbiting a red giant star
larger than the Sun and located some 290 million light years from Earth.
The star Kepler-56 is becoming a red giant star
Overhead in the night sky you can expect to observe Jupiter the biggest planet in our solar system, the Orion Nebula where stars are created, the Antromeda Galaxy, and Belelgeux a red giant star
700 times the size of our Sun.
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.
