How old is our universe

Answered By: Abraham Jenkins Date: created: Oct 02 2021

13.77 billion yearsThe universe is (nearly) 14 billion years old, astronomers confirm.

What will happen when the sun dies

Answered By: Hugh Powell Date: created: Sep 05 2022

After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. Astronomers aren’t sure exactly how close the Sun’s outer atmosphere will come to Earth.

What is the longest living star

Answered By: Oscar Brooks Date: created: Jul 22 2021

Red DwarfsRed dwarf stars make up the largest population of stars in the galaxy, but they hide in the shadows, too dim to be seen with the naked eye from Earth. Their limited radiance helps to extend their lifetimes, which are far greater than that of the sun.

What happens before a star dies

Answered By: Herbert Miller Date: created: Nov 22 2021

When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This entire process will take a few billion years.

Why do stars twinkle

Answered By: Gabriel Henderson Date: created: Dec 24 2021

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.

Will our Sun become a black hole

Answered By: Jordan Peterson Date: created: Jun 22 2022

No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.

Answered By: Cameron Lewis Date: created: Dec 13 2021

A hypergiant (luminosity class 0 or Ia+) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds. The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.

Do stars explode when they die

Answered By: Carlos Hayes Date: created: Aug 14 2021

Stars die because they exhaust their nuclear fuel. The events at the end of a star’s life depend on its mass. … Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.

How many years a star can live

Answered By: Leonars Harris Date: created: Sep 11 2022

Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.

Can stars live longer than 10 billion years

Answered By: Neil Carter Date: created: Jul 30 2022

A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long. Stars begin their lives as dense clouds of gas and dust. … If the star is less massive than several times the mass of the sun, it will eventually become a white dwarf.

Do brighter stars die faster

Answered By: Eric Ward Date: created: Jul 30 2022

Heavier stars thus burn their fuel much faster than less massive ones do and are disproportionately brighter. … A massive star such as the red Betelgeuse in Orion, in contrast, approaches its demise much more quickly. It has been spending its fuel so extravagantly that it cannot be older than about 10 million years.

Question: What Are 4 Causes Of Erosion?

What are 4 things that cause erosion? Liquid water is the major agent of erosion on Earth.Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.. What are the human activities that cause soil erosion? Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land. How can erosion be prevented? Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water.
