Depending on its size, the star becomes either an average star or a massive star. The average star then becomes a red giant, a planetary nebula, and ends its life as a white dwarf. The massive star turns into a red supergiant, goes supernova, and ends up as a neutron star or a black hole – again, depending on its size.

What is the lifespan of a red supergiant star?

around 3 to 100 million years
Red supergiants are usually 10 to 40 times or more massive than our Sun, and they typically have a lifespan of around 3 to 100 million years.

What is the life cycle of a red supergiant?

Depending on its size, the star becomes either an average star or a massive star. The average star then becomes a red giant, a planetary nebula, and ends its life as a white dwarf. The massive star turns into a red supergiant, goes supernova, and ends up as a neutron star or a black hole – again, depending on its size.

Are red giant stars old?

But these giant stars are just going through a natural phase of life, getting old and dying. By the time our sun, for example, ends its life as a white dwarf, it will have lived for ten billion years.

What happens when a red supergiant dies?

The supergiant explodes as a supernova. The outer layers are blown off into space leaving behind the star’s core, which begins to shrink.

What is a red supergiant for kids?

A red supergiant star is a larger and brighter type of red giant star. Red supergiants are often variable stars and are between 200 to 2,200 times bigger than the Sun. An example of a red supergiant star is Antares. 119 Tauri, Betelgeuse, Mu Cephei, and VV Cephei are other famous examples of red supergiants.

Will Earth survive the red giant phase?

Earth may just outrun the swelling red giant but its proximity, and the resulting rise in temperature, will probably destroy all life on Earth, and possibly the planet itself.

How long is protostar stage?

between 100,000 and 10 million years
During this time, and up until hydrogen burning begins and it joins the main sequence, the object is known as a protostar. This stage of stellar evolution may last for between 100,000 and 10 million years depending on the size of the star being formed.

What are the 7 stages of star?

The formation and life cycle of stars

  • A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula.
  • Protostar. As the mass falls together it gets hot.
  • Main sequence star.
  • Red giant star.
  • White dwarf.
  • Supernova.
  • Neutron star or black hole.

Will the Sun explode in 2022?

Luckily for us here on Earth, the eruption on February 15, 2022 occurred on the farside of the sun, the side facing away from our planet. But ESA and NASA predict geomagnetic storms are possible in the next few days as the active region on the sun responsible for the blast turns toward us.

What does a red supergiant do?

These enormous, cool stars are red supergiants. Supergiants burn all the helium in their cores within a few million years. They then start to burn the carbon. This continues with heavier and heavier elements until the star contains a core of iron.

What are the characteristics of red supergiants?

Red supergiants have the largest radius of all known stars. They have low surface temperatures (for stars!) of below 4,100 K. This causes them to shine with a red colour. The star Betelgeuse in the constellation of Orion is a red supergiant. Red supergiants evolve from large main sequence stars that contain more than 8 times the mass of our Sun.

What is the largest red supergiant star?

Red supergiant star. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares are the brightest and best known red supergiants (RSGs), indeed the only first magnitude red supergiant stars .

How do stars become red supergiants?

At various points in a star’s life, different things will happen depending on the size of the star. Only large stars with a mass of about ten solar units will go on to become red supergiants. The famous star, Betelgeuse, is a red supergiant star in the constellation Orion.

How big do stars have to be to become supergiants?

Only large stars with a mass of about ten solar units will go on to become red supergiants. The famous star, Betelgeuse, is a red supergiant star in the constellation Orion.
