Has the Sun's surface tempurature changed?

Answer 1

Yes the temperature of the sun keeps on increasing and finally it will develp into a red giant eating up the first 4 planets. When the sun is using up its last bit of energy it will burn very hot and finally form a white dwarf and gradually forms a black hole

Answer 2

The sun is a typical star of intermediate size and luminosity. Sunlight and other radiation are produced by the conversion of hydrogen into helium in the sun's hot, dense interior . Although this nuclear fusion is changing 600 million metric tons of hydrogen into helium each second, with a net conversion to energy of at least 4 million tons of mass, the sun is so massive (2 × 1030 kg, or 4.4 × 1030 lb) that it can continue to shine at approximately its present brightness for several billion years. This stability has allowed life to develop and survive on earth.
For all the sun's steadiness, it is an extremely active star. On its surface dark sunspots bounded by intense magnetic fields come and go in cycles of approximately 11 years; sudden bursts of charged particles from solar flares can cause auroras and disturb radio signals on earth; and a continuous stream of protons, electrons, and ions leaves the sun and moves out through the solar system, spiraling with the sun's rotation. This solar wind shapes the ion tails of comets and leaves its traces in the lunar soil, samples of which were brought back from the moon's surface by piloted U.S. Apollo spacecraft and unmanned Soviet Luna spacecraft .

Answer 3

Yes the sun’s surface energy output has risen over the last century. The Sun’s output varies over time, thus hot eras and ice ages. We are currently in a time of rising temperature where the ice caps are slowly receding thus less solar energy is reflected into space and temperatures rise even more. This cycle has been going on for billions of years and will for billions more.

Answer 4

The Suns emission of energy fluctuates in cycles, with occasional bursts known as solar flares. As it does so, a constant stream of particals - the solar wind - is flung out into space.
The sun spots are dark patches on the surface where temps fall to around 3,700 deg C. Their number varies in an 11 yr cycle. Surface temp 5,600 deg C, Core temp 15.6 million deg C.

Answer 5

Thats what the sun spots are,the sun is like billions of nuclear bombs expoding every second ,so the answer to your question would be yes and no because these spots are like the nuclear waste cooled and then dissapear and scatter into outer space,thats why it gives of deadly radiation wich our ozone layer blocks that deadly radition from the cooled solar spots on the sun

Answer 6

Actually the suns temperature is constantly increasing as it burning more and more hydrogen.It is said that after 5 billion years it will grow extremely big and will swallow the first three planets that is mercury,Venus and EARTH due to its increased gravity!!!!!!!!!!!!!!

but after another 5 billion years it will have no more hydrogen and will become a white dwarf star!

Answer 7

The surface temperature is in a state of constant change

Answer 8

Yes, the Sun is slowly cooling, but we have several billion years yet before we need to worry.

Answer 9

i think that that the sun temperature may have changed because their have been said according to ancient god that one day it will come then their the sun will not exist.

so by this means we can say that the temperature of the sun may have decreased.by this mean

Answer 10

Since when?
