In determining the distance of the sun the astronomer only employs a principle which you daily take advantage of in estimating distance ... of the moon there is however no doubt that the red flames belong to the sun. The sun is encircled by rings of zones, corresponding to the rings of Saturn. The rings ... more, recent science has actually discovered well known substances in the incandescent atmosphere of the sun, bringing the flame into close analogy to terrestrial combustion. The following metals have already been ...

... collapse will initiate a rise in temperature which will then force additional hydrogen surrounding the Sun's spent core to begin fusing into helium which will rapidly elevate the temperature, causing it to expand into a Red Giant star. Our Sun has now entered the Red Giant phase as new-found internal energy reserves drive its ... of contraction and expansion happens again, but only briefly, for a few million years. The Sun will now rapidly expand to almost within reach of Earth's orbit, and then, at ...

... in its orbit. Slowly they began to draw themselves together the same way that our Sun did. However, because they were so much smaller and less dense than the dust-cloud that formed the Sun, they did not generate the same intense heat and pressure that is needed to create ... generally unlikely to find water or ice on those planets that form close to a sun because they will be very hot and will usually also lack atmospheres that are dense ...

... powered by various sources like a coal burning fire. But the times calculated for the Sun if it were burning like a giant lump of coal could not account for the ... soon go out The mystery remained until the twentieth century when scientists discovered that the Sun was powered by fusion-the conversion of hydrogen into helium with the enormous release of energy. Nuclear fusion has provided the Sun with enough energy for its first 4.6 billion years and will allow it to ...

... of their extreme mass and size. If Betelgeuse were dropped in the position where our Sun is, it would extend all the way out beyond the orbits of Mars and reach ... -an astonishing 600 million miles across Now once you understand that fact, and that the Sun is a small stable star with the next closest star over 4.28 light years away, you can easily see that the Sun will have very little influence over the life of the other 400 billion stars found ...

... 872,000 miles across. About 109 Earths could fit across the diameter of the Sun. Because the Sun is a ball of gas, it is slightly distorted and rotates faster at the ... oblate at the equator but for practical purposes in normal discussions, you can consider the Sun to be round.

... is moving in space. Just as the Earth has a yearly orbit around the Sun, our Sun also orbits the center of our Milky Way Galaxy once every 230 million years. It is amazing to think about the fact that the last time our Sun passed through this area of the Milky Way Galaxy was when the dinosaurs were still ... gas that formed in this region of space and eventually gravitationally collapsed to form the Sun and all the planets, comets and asteroids in our solar system. ---- Answer provided by Jim ...

A review of some of the new results from SOHO is given here, with a ... include a rather unexpected feature of the nature of so-called active regions on the Sun, the discovery of new solar phenomena, such as solar tornadoes and jets, a new view of the nature of the quiet Sun, and a new insight into the way the Sun ejects vast clouds known as coronal mass ejections into space.
