Newly spotted red giant could be one of the oldest stars in the universe

The video discusses the discovery of a red giant star located 500 light years from Earth, which may be one of the oldest stars in the cosmos. According to a study published in the Monthly Notices of the Royal Astronomical Society, this red giant is likely a descendant of the first stars created by the Big Bang, which are believed to be extinct. The red giant has the lowest iron content ever detected, suggesting it is much older than metallic stars. The first stars were composed of hydrogen and helium, and their supernova explosions created metal elements. This explains why the red dwarf, a progeny of the first stars, contains minimal iron.

What is the significance of the star located 500 light years from Earth?

• It is the largest star ever discovered.

• It might be one of the oldest stars in the cosmos.

• It is the closest star to Earth.

Why is the red giant star considered a descendant of the first stars?

• It has a high amount of iron.

• It is located in the galactic core.

• It has the least amount of iron ever detected.

• It is the hottest star in the galaxy.

What elements were the first stars primarily made of?

• Iron and nickel

• Silicon and magnesium

• Hydrogen and helium

• Carbon and oxygen

What happens when the first stars die?

• They turn into black holes.

• They explode into supernovas.

• They become neutron stars.

• They shrink into white dwarfs.

Why does the red dwarf contain so little iron?

• It is a newly formed star.

• It is a direct progeny of the first stars.
