How do stars fight?

How do stars fight?

Like humans, stars grow old and eventually die. Also like humans, stars sometimes fight with their closest friends. During the battle, one of the stars grew so large it was able to engulf the other, which then spiraled and caused the original star to shed its outer layers.

What exactly is a star?

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.

How does a star’s life begin?

All stars begin their lives from the collapse of material in a giant molecular cloud. These clouds are clouds that form between the stars and consist primarily of molecular gas and dust. When the protostar starts fusing hydrogen, it enters the “main sequence” phase of its life.

How old are the stars we see?

For the most part, the stars you see with the naked eye (that is, without a telescope) are still alive. These stars are usually no more than about 10,000 light years away, so the light we see left them about 10,000 years ago.

What are the 5 stages of a 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.

What are the 6 stages of a star?

Formation of Stars Like the Sun


What are the 7 stages of a star?

Can a star turn into a planet?

Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen.

Do Dead stars still shine?

After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a “black dwarf.”

Why do stars twinkle?

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.

What is star death?

When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. This may be millions of kilometres across – big enough to swallow the planets Mercury and Venus. After puffing off its outer layers, the star collapses to form a very dense white dwarf.

What phase of life does a star go through?

If the star is big enough to fuse hydrogen atoms into helium, it will enter the phase that our Sun is in, called the main sequence phase. A star will enjoy most of its life in the main sequence phase.

What is the meaning of the Bronze Star?

The Bronze Star is a 1½-inch diameter star made of bronze and it hangs from a red ribbon with a vertical blue stripe surrounded by thin vertical white stripes. On the reverse of the star is the inscription, “HEROIC OR MERITORIOUS ACHIEVEMENT,” along with the recipient’s name.

How many people have been awarded the Bronze Star?

The Bronze Star was awarded in the following conflicts: 1 World War II: 395,380 recipients. 2 Korean War: 30,359 recipients. 3 Vietnam War: 719,969 recipients: 549,343 for achievement and service and 170,626 for valor. 4 Operation Iraqi Freedom: 102,345 recipients: 99,886 for achievement and service and 2,459 for valor.

What is the best hypothesis about the length of Star Life?

Choose from the following hypotheses regarding length of star life: 1) The bigger a star is, the longer it will live. 2) The smaller a star is, the longer it will live. Now, for whichever hypothesis you chose, type a 1-3 sentence explanation for why you think this is so. To find out if you are correct, read the following explanation carefully
