The phenomenon was observed by the ESA's (European Space Agency) Integral space observatory, which saw a red giant star
revive its dead companion star with a flash of X-rays.
Our Sun will swell to become a similar red giant star
in about five billion years.
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.
A red giant star
(the far-future fate of our Sun) has a much weaker pull at its surface, so you'd be 50 times lighter.
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.
In about five billion years our Sun will become a red giant star
, swelling to immense proportions and engulfing Mercury and Venus.
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.
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.
50 Southwell Alpha Tauri, more commonly known as Aldebaran, is a red giant star
located in the zodiac constellation of Taurus some 65 light years (or 400 trillion miles) away from Earth.
In about 5 billion years, our sun will grow into a red giant star
